SECTION 1. General Information

1.1 Introduction

This manual provides installation and operation instructions for the Lite2 Model LG pool and spa heater. Read these installation and operation instructions completely before proceeding with the installation. Consult the Jandy factory, or local factory representative, with any questions regarding this equipment.

Certain sections of this manual are specific to either United States or Canadian installations, and are labeled as such.

The Lite2 model LG heater is a self contained standing pilot unit and requires no external power.

The Lite2 heater is specifically designed for heating fresh water swimming pools and spas, and with proper installation and care, they will provide years of reliable service. Do not use the heater to maintain pool or spa water temperature below 70°F. Do not use it as a heating boiler or general service water heater or to heat salt water. Consult your dealer for the appropriate Jandy products for these applications.

1.2 Consumer Information and Safety

The Lite2 Pool/Spa heater is designed and manufactured to provide many years of safe and reliable service when installed, operated and maintained according to the information in this manual and the installation codes referred to in later sections. Throughout the manual safety warnings and cautions are identified by the " comply with all of the warnings and cautions.

1.2.1 Spa/Hot Tub Safety Rules

The following “Safety Rules for Hot Tubs,” recommended by the U.S. Consumer Product Safety Commission, should be observed when using the spa.

" symbol. Be sure to read and

WARNING

The U.S. Consumer Product Safety Commission warns that elevated water temperature can be hazardous. Consult heater operation and installation instructions for water temperature guidelines before setting temperature.

1. Spa or hot tube water temperature should never exceed 104°F (40°C). One hundred degrees Fahrenheit (100°F [38°C]) is considered safe for a healthy adult. Special caution is recommended for young children.

2. The drinking of alcoholic beverages before or during spa or hot tub use can cause drowsiness which could lead to unconsciousness, and subsequently result in drowning.

3. Pregnant women take note! Soaking in water above 102°F (38.5°C) can cause fetal damage during the first three months of pregnancy (which could result in the birth of a braindamaged or deformed child). If pregnant women are going to use a spa or hot tub, they should make sure the water temperature is below 100°F (38°C) maximum.

4. The water temperature should always be checked with an accurate thermometer before entering a spa or hot tub. Temperature controls may vary by as much as 4F° (2C°).

5. Persons with a medical history of heart disease, diabetes, circulatory or blood pressure problems should consult their physician before using a hot tub or spa.

6. Persons taking any medication which induces drowsiness (e.g., tranquilizers, antihistamines, or anticoagulants) should not use spas or hot tubs.

7. Prolonged immersion in hot water can induce hyperthermia.

Hyperthermia occurs when the internal body

temperature reaches a level several degrees above the normal body temperature of 98.6°F (37°C). Symptoms include dizziness, fainting, drowsiness, lethargy, and

Page 2

an increase in the internal body temperature. The effects of hyperthermia include:

• Lack of awareness of impending hazard

• Failure to perceive heat

• Failure to recognize need to leave spa

• Physical inability to leave spa

• Fetal damage in pregnant women

• Unconsciousness resulting in a danger of drowning

1.2.2 Swimming Pool Energy Saving Tips

Water Pik Technologies offers the following

recommendations to help conserve fuel and minimize the cost of operating your pool heater without sacrificing comfort.

1. The American Red Cross recommends a maximum water temperature of 78°F (25°C). Use an accurate pool thermometer. A difference of 4F° (2C°) , between 78°F and 82°F (26°C and 28°C), will use as much as 40% more gas.

2. Carefully monitor the water temperature of your pool in the summertime. You can reduce heater usage due to warmer air temperatures.

3. Find the proper setting on the pool heater temperature control and use the TEMP-LOK to discourage further adjustments.

4. Set the filter time clock to start the pump no earlier than 6:00 AM during the pool heating season. This is the time when nightly heat loss balances.

5. If the pool is only going to be used on weekends, reduce the heater temperature control setting by 8 or 10 degrees during the week. Reset it to the desired temperature level a day or so before you plan to use the pool.

6. During the winter or when on vacation for longer than a week, shut down the heater by following the shutdown instructions found on the inside of the heater.

7. Where possible, shelter the pool from prevailing winds with well-trimmed hedges or other landscaping, cabanas, or fencing.

8. Always use a pool cover when practical. Besides providing a valuable safety feature, a pool cover will reduce heat loss, conserve chemicals, and reduce the load on filter systems.

1.3 Warranty

The Lite2 heater is sold with a limited factory warranty. Details are specified on the back cover of this manual.

Make all warranty claims to an authorized Jandy representative or directly to the factory. Claims must include the heater serial number and model (this information can be found on the rating plate), installation date, and name of the installer. Shipping costs are not included in the warranty coverage.

The warranty does not cover damage caused by improper assembly, installation, operation or field modification. Also, damage to the heat exchanger by corrosive water, is NOT covered by the warranty. See Section 8.1 for maintaining proper pool water chemistry.

NOTE: Keep this manual in a safe place for future reference when inspecting or servicing the heater.

1.4 Codes and Standards

The Lite2 pool and spa heater is design certified by CSA (Canadian Standards Association) as complying with the latest edition of the “Standard for Gas Fired Pool Heaters”, ANSI Z21.56 in the USA and CSA-4.7 in Canada.

All Jandy heaters must be installed in accordance with the local building and installation codes as per the utility or authorities having jurisdiction. All local codes take precedence over national codes.

2.3.3 Flooring

The heater shall be installed on a level floor of

noncombustible construction or on fire-resistant slabs or arches. Noncombustible flooring is defined as flooring material and surface finish not capable of being ignited and burning and with no combustible materials against the underside. Acceptable materials are those consisting entirely of a combination of steel, iron, brick, tile, concrete, slate, glass or plaster. Do not install the heater directly on a combustible wood or carpet floor without placing a noncombustible platform between the floor and the heater.

The heater can be installed on a combustible floor if a noncombustible base assembly, available from Jandy, is used. See the heater rating plate or the Parts List (Section 11) of this manual for the appropriate base part number. Heaters must never be

installed directly on carpeting.

As an alternative to the Jandy noncombustible base plate, in the United States, the National Fuel Gas Code allows a heater to be placed on a combustible surface when there is a platform under the heater made of hollow masonry no less than 4 inches (102 millimeters [mm]) thick, covered with sheet metal at least 24 gauge thick and extending beyond the full

m) horizontally or four (4) feet (1.22 m) vertically between the heater exhaust point and any door, glass opening, or gravity inlet to a building. In Canada, the heater must be installed so that the exhaust point of the heater is at least ten (10) feet (3.0 m) from any building opening (see Figure 3).

Model LG Pool and Spa Heater

WARNING

United States

Do not install the heater with the top of the vent assembly within 4 feet (1.22 m) horizontally and 4 feet (1.22 m) vertically of any opening into a building.

Canada

Do not install the heater with the top of the vent assembly within 10 feet (3.05 m) of any opening into a building.

The top surface of the heater must be at least three(3) feet above any forced air inlet, or intake ducts located within ten(10) feet horizontally.

If the heater is installed under an overhang, there must be a minimum clearance of 5 feet (1.5 m) above the top of the heater and the structure should not overhang the heater more than 12 inches (0.30m). The area under the overhang must be open on three sides. This prevents combustion gases from being diverted into living areas through doors, windows, or gravity inlets.

Page 7

Figure 3. Outdoor Heater Installation.

If the heater is installed close to a structure, protect it from rain water runoff with rain gutters on the roof or other measures. Do not locate the heater near irrigation sprinkler systems that could spray water on it. Water from sprinklers may cause damage to controls and electronic components.

Avoid locations where wind deflection off nearby structures might cause downdraft conditions. Where downdraft conditions exist, locate the heater at least 3 feet (0.91 m) from vertical surfaces (e.g., nearby buildings and walls). The addition of a vent cap may be necessary.

In Florida it is required that the heater be securely fastened to the equipment pad. Use a size 1/4" x 1-1/2" long stainless steel Tapcon® type concrete screws and washers at each of the four tabs located at the base of the heater. Mounting the appliance in this manner meets the applicable requirements of the Florida Building Code.

Mounting screws are not provided with this heater. After placing the heater on the equipment pad, drill a hole in the concrete at each of the four tabs on the feet of the heater. (The correct size drill bit is usually provided with the concrete screws when purchased). Place a screw in each of the holes and fasten the heater to the equipment pad (see Figure 4).

Do not over torque the screws.

Figure 4. Anchor Heater To Equipment Pad

2.3.5. Indoor and Outdoor Shelter Installations

An outdoor shelter (Canada only) is an unoccupied enclosure which does not communicate directly with occupied areas. All indoor installations and outdoor shelter installations require the addition of a factory approved drafthood. The drafthood must be installed without modification and in accordance with all local, state, provincial and national codes.

These codes, standards and Water Pik Technologies require that the heater be properly vented as outlined in this manual. Proper ventilation of exhaust and combustion air are essential for the safe and

efficient operation of the heater (See Section 3). An approved draft hood may be purchased from your local Jandy distributor. See Section 11 (Parts List) of this manual for the correct part number for you model and size heater.

In general, these requirements specify that the room in which a heater is installed should be provided with two permanent air supply openings; one within 12 inches (305mm) of the ceiling, the other within 12 inches (305mm) of the floor. All indoor installations must have openings to outside air for combustion, ventilation, and dilution of flue gases from inside the building (see Figure 5 and Table 3). Water Pik Technologies does not recommend indoor installations that do not provide combustion air from outside the building.

All outdoor shelter installations (Canada only) must have uninterrupted openings to outside air for combustion and ventilation. The installation must be in accordance with the latest edition of CAN/CSAB149.1. Water Pik Technologies does not recommend outdoor shelter installations that depend on internal air for combustion. Combustion air should be ducted to the heater from outside the structure.

Outside Air Supply: When combustion air is supplied directly through an outside wall, each opening should have a minimum free area of one square inch per 4,000 BTU/h (1.2kW) input of the total input rating of all appliances in the enclosed area. If air is provided

through horizontal ducts, each opening and duct must provide one square inch of flow area for each 2000

SECTION 3. Venting

BTU/h (0.6 kW). These requirements are summarized in Table 3. Note that the areas specified are net free areas and should be increased by 50 percent when the openings are covered by screens, louvers, grills or

other protective covers (see Figure 5 and Table 3).

The heater location must provide sufficient air supply for proper combustion and ventilation of the surrounding area as outlined in the latest edition of ANSI standard Z223.1 or in Canada, CAN/CSAB149.1, and any local codes that may be applicable.

Note: In Canada, follow Canadian Standard, CAN/CSA-B149.1 or local codes.

Exhaust Fans or Vents: Any equipment which

Model LG Pool and Spa Heater

exhausts air from the room where the heater is installed can deplete the combustion air supply or reverse the natural draft action of the venting system. This could cause flue products to accumulate in the room. Additional air must be supplied to compensate for such exhaust.

The information in Table 3 is not applicable in installations where exhaust fans or blowers of any type are used. Such installations must be designed by qualified engineers.

If a blower or fan is used to supply air to the room, the installer should make sure it does not create drafts which could cause nuisance shutdowns of the pilot.

The heater must be completely isolated and protected from any source of corrosive chemical fumes such as those emitted by trichlorethylene, perchloroethylene, chlorine, etc.

WARNING

Do not store any chemicals, cleaners, or other corrosive material near combustion air openings or in the room. Avoid locating dryer vents in the vicinity of combustion air openings. Failure to prevent corrosive materials from mixing with combustion air can result in reduced heater life and unsafe heater operation.

3.2.2. Indoor and Outdoor Shelter Installations

WARNING

Vent pipe diameter must be as required by the National fuel Gas Code ANSI Z223.1 or the Canadian Installation Codes for Gas Appliances CAN/CSA-B149.1. Undersize pipe can result in inadequate venting and oversize pipe can result in vent condensation. In either case the result can be release of combustion products to the indoors. This can cause serious injury or death by carbon monoxide poisoning or asphyxiation.

3.2 Vent Pipe Sizing and General Installation

3.2.1. Outdoor Installations

For outdoor installations, exhaust venting

considerations will determine the placement of the heater (See Section 2.3.4). If the heater cannot be placed so as to meet the requirements stated in Section

2.3.4, a vent pipe and cap may be added to the heater

to move the exhaust vent opening to a position that complies with the requirements. When the heater is installed in areas of high wind or when unavoidably installed near a vertical obstruction where downdrafting may occur, it may be desirable to add a vent cap directly to the top of the heater. In all cases, vent pipes and caps must be of the same diameter as the exhaust outlet of the heater. Approved vent caps may be obtained through your Jandy distributor.

All indoor installations and outdoor shelter installations require the addition of a factory approved drafthood. The drafthood must be installed without modification.

All vent installations must be made in accordance with all local, state or provincial codes and with:

1. Chapter covering "Venting of Equipment" of the

national Fuel Gas Code, ANSI 223.1 latest

edition , or the applicable provisions of the local

building codes.

2. In Canada , CAN/CSA-B149.1.

Avoid long horizontal runs of the vent pipe, and 90° elbows, reductions and restrictions. Horizontal runs should have at least a 1/4 inch rise per foot (20mm per meter) in the direction of flow.

Avoid terminating heater vents near air conditioning or air supply fans. The fans can pick up exhaust flue products from the heater and return them inside the building, creating a possible health hazard.

Do not locate the vent terminal where flue products could strike against building materials and cause degradation.

Vent opening should be well away from trees or other obstructions that would prevent free air flow to and from vent terminal. Do not terminate the vent under decks, stairways, or car ports.

Be sure to support all venting so that connections

Page 10

will not separate and so that the weight of the vent pipe does not rest on the heater draft hood. All connections should be made with rustproof sheet metal screws. Do not weld or fasten the vent pipe to the heater draft hood. The draft hood and heater top must be easily removable for normal heater service and inspection.

The draft hood outlet is to be connected to an unobstructed vent pipe of the same diameter, terminating outside the building. The vent must terminate at least two (2) feet (0.61 m) above the highest point of the roof or other object that is within ten (10) feet (3.05 m) of the vent termination. The vent pipe must have a listed vent cap which allows a full equivalent opening for flue products (see Figure 5). The top of the vent cap must be at least five feet in vertical height above the drafthood outlet.

Type “B” double wall or equivalent vent pipe is recommended. However, single wall metal vent pipe may be used as specified in the latest edition of the National Fuel Gas Code ANSI Z223.1 or in Canada CAN/CSA-B149.1

IMPORTANT NOTE: Do not use sheet metal screws at the snap lock joints of Type B gas vents.

WARNING

The Lite2 pool and spa heaters are designed for use with either natural gas or LP gas. Check the rating plate on the inner panel to be sure that the heater is configured to use the type of gas being supplied. DO NOT

ATTEMPT TO CONVERT THIS HEATER FOR USE WITH ANY OTHER TYPE OF

FUEL.

1. Gas piping installation must be in accordance with the latest edition of ANSI Z223.1 and all local codes. In Canada, the installation must be in accordance with CAN/CSA-B149.1 and all local codes that apply.

When venting multiple appliances through one common duct, each appliance must have it’s own vent temperature limit switch. All vent limit switches must be wired in series so as to prevent any appliance from firing in the event of a blocked vent. Refer to ANSI Z223.1 or, in Canada, to CAN/CSA-B149.1 for more information on multiple venting.

3.2.3 Inspection and Replacement of Existing Vent System with New Components

If the Lite2 is being installed to replace an existing pool heater, it is recommended that a new appropriate venting system be installed with the new heater. However, if an existing venting system must be used, be sure to carefully inspect the venting system to ensure that it is in good condition and continues to be appropriate for the Lite2 heater. Replace any parts that are not in good and serviceable condition with new parts before completing the pool heater installation.

SECTION 4. Gas Connections

2. Check the gas supply to be sure that it is the same as the gas indicated on the heater’s rating plate. Lite2 LG heaters, as shipped from the factory, are certified to operate within the altitude range indicated on the rating plate. If a field conversion to a different altitude range should be necessary, manifold kits are available for changing the altitude range of the heater. See Table 1 in section 1.7.1 of this manual to determine the correct altitude designation for your heater. Refer to Section 11 “Parts List” to order the correct part number of the manifold kit needed. When changing the altitude range of the heater, be sure to fill out the altitude conversion label, included in the kit. Apply the label on the inner panel of the heater, next to the original rating plate.

CAUTION

Permanent damage to the gas valve will occur if the following procedures are not followed.

4.1 Gas Supply and Piping

Review the following general instructions before

continuing the installation.

3. Use the figures in Table 4 to size the gas inlet piping from the gas meter to the heater. Check all local codes for compliance before installing the heater.

Notes:

*1. These numbers are for natural gas (0.65 Sp. Gr.) and are

based on 1/2 inch (13mm) water column pressure drop. Check supply pressure with a manometer, and local code requirements for variations. For liquefied petroleum gas, reduce pipe diameter one size, but maintain a3/4inch (19mm) minimum diameter.

2.Check supply pressure and local code requirements before proceeding with work.

3.Pipe fittings must be considered when determining gas pipe sizing.

NOTE: The maximum inlet gas pressure must not exceed the specified value. The minimum value listed is for the purpose of input

adjustment. Refer to Table 5.

8. Before operating the heater, test the complete gas supply system and all connections for leaks using a soap solution. Do not use an open flame.

CAUTION

Some leak test solutions (including soap and water) may cause corrosion or stress cracking. Rinse the piping with water after testing.

Figure 6. The proper design for a sediment trap/drip leg.

4. Install a sediment trap (drip leg) ahead of the gas controls (see Figure 6). Fit the trap with a threaded cap which can be removed for cleaning.

5. Install a manual gas shutoff valve for service and safety. Do not use a restrictive gas cock. DO NOT USE FLEXIBLE GAS PIPING, it will restrict the gas flow to the heater.

6. Disconnect the heater and its individual shutoff valve from the gas supply system during pressure testing of the system at pressures higher than 1/2 pounds per square inch (psi) (3.45 kilopascals [kPa]). If the test pressure is equal to or less than 1/2 psi (3.45 kPa), close the manual shutoff valve on the heater during the piping pressure test.

7. If the gas supply pressure is less than required, check for undersized pipe between the meter and the heater, a restrictive fitting, or an undersized gas meter. Gas supply pressures to the heater are listed in Table 5.

4.2 Manifold Pressure

Confirm that gas supply pressure is correct. If the gas supply pressure is less than required, check for undersized pipe between the meter and the heater, a restrictive fitting, or an undersized gas meter. Gas supply pressures to the heater, when it is operating, are listed in Table 5.

CAUTION

Manifold gas pressure for the Lite2 Lg natural gas heaters should be set at 4" WC. Propane heaters should be set to 9" WC.

The manifold pressure may be checked by connecting a manometer to the pressure port on the outlet side of the valve. You will need to remove the 1/8"

Page 12

NPT protective plug form the port and install the appropriate 1/8" NPT fitting to connect your manometer. The pressure will be zero when the heater is not running. When the heater is operating the manifold gas pressure should be 4.0" WC for natural gas heaters and 9.0" WC for LP gas heaters.

To adjust the manifold gas pressure, first remove the slotted cap on the top of the gas valve to the right of the control knob. Under the slotted cap is a slotted plastic screw which increases the manifold pressure when turned clockwise and decreases the manifold pressure when turned counterclockwise.

After measurements, and adjustments if necessary, have been made, make sure to replace the 1/8" NPT plug on the manifold pressure ports, and the cap on the manifold pressure adjustment screw. It is extremely important to replace these parts before leaving the installation. Failure to do so can result in damage to property or injury or death.

With the heater firing, the pressure must be within the range shown in Table 5. Also check the pressure with the heater off.

4.3 Special Precautions for LP Gas

LP Gas is heavier than air and can therefore more readily collect or “pool” in enclosed areas if provision for proper ventilation is not made. Installation of pool heaters in enclosed areas such as pits is not recommended. However, if such an installation is required be sure to pay special attention to proper ventilation for LP gas. Locate heaters a safe distance from LP gas cylinders and filling equipment. In the United States, consult the "National Fuel Gas Code" (NFPA 54 / ANSI Z223.1, latest edition) or in Canada,

the "Natural Gas and Propane Installation Code" (CAN/CSA-B149.1), and any local codes and fire protection authorities about specific installation restrictions in your area.

SECTION 5. Water Connections

5.1 Water Piping

Figure 7 illustrates typical piping for pool equip-

ment in pool/spa combination pools.

For normal installations, do not install a shutoff valve or any kind of variable restriction in the water piping between the heater outlet and the pool/spa. In special installations where a shut-off valve, diverter valve or other variable restriction is required in the plumbing between the heater outlet and the pool, Water Pik Technologies recommends the installation of a pressure relief valve on the heater (see Section

5.6).

Arrangement of pool system components other than as illustrated in these diagrams can affect the operation of the heater’s water pressure switch. Location of the heater above or below the pool water surface can also affect operation of the switch. In general, the pressure switch can be adjusted to accommodate this effect if the heater water connections are no more than six feet below the pool water surface and no more than 15 feet above it. See instructions for pressure switch adjustment (Section

7.5) in the heater start-up section of this manual for more information about this.

Note that when pool equipment is located below

Note: When using metal pipe as heat sink, join metal and PVC/CPVC, using metal male and PVC/CPVC female connection.

Figure 7. Typical installation.

Model LG Pool and Spa Heater

Page 13

the pool surface a leak can result in large scale water loss or flooding. Water Pik Technologies cannot be responsible for such water loss or flooding or the damage caused by it.

For special installations such as water connections below the water level of the pool, or for other questions contact the Jandy Technical Service department at (707)-776-8200 ext 260.

5.2 Check Valve Installation

The heater must be protected from backsiphoning of water, which can result in dry starts. If there is any chance of back-siphoning, provide a check valve between the pool and the filter pump inlet.

When an automatic chemical feeder is installed in the plumbing, it must be installed downstream of the heater (see Section 5.7). A check valve must be installed between the heater and the chemical feeder to prevent back-siphoning of chemically saturated water into the heater where it will damage the components.

5.3 Automatic Flow Control Valve

The inlet/outlet header of the Lite2 comes equipped with an automatic flow control valve. The automatic flow control valve maintains the proper flow through the heater at rates up to approximately 125 Gallons Per Minute (GPM) (474 liters per minute [LPM]). If the filter system flow rate is higher than approximately 125 GPM (474 LPM), install a manual bypass valve (see Figure 7), then perform a temperature rise test (see Section 7.6) and adjust the flow using the bypass valve until the proper temperature rise is obtained.

5.4 Reversible Water Connections

Water Pik Technologies ships the Lite2 heater with the water connections on the right side. The Lite2 heater can be installed with the water connections on either side. It could be necessary, or helpful, to switch the connections to the left side to improve access for installation and service. Perform this modification before installing the heater using the following procedures:

1. Remove heater door.

2. Remove all 8 hex-head screws fastening the top

and lift the top assembly straight up (see Figure

8).

3. Remove rainshield assembly and set it aside.

4. Remove screws that fasten the gap closures to

the jacket and put them aside. Remove gap

closures.

Figure 8. Heat exchanger reversal.

Figure 9. Flue collector hold-down brackets.

Page 14

5. Remove the screws securing the two flue collector hold down clamps and remove the clamps (see Figure 9). Remove flue collector.

6. Remove the three rubber jacket/plug grommets and drain plugs (see Figure 8). One is located under the water connections on the right side. The other two are on the left side of the heater.

7. Tag and disconnect the white wire on the pressure switch (PS) and the white wire on the Fireman's switch terminal which leads to the high limit switch.

8. Remove plastic tie wraps and pull the white wires out of the front compartment through the vestibule cover and coil them on the heat exchanger.

9. Unscrew the brass compression fitting securing the pressure switch to the inlet/outlet header. Remove tube from header and gently bend it out of the way.

Figure 10. Temperature sensing bulb.

10. Loosen the screw securing the temperature sensing bulb retainer bracket. Slide the retainer bracket off the bulb flange and remove the bulb from the header (see Figure 10). Pull pressure switch tube through the hole in the vestibule cover and into the vestibule (controls compartment), then pull thermostat bulb assembly through same hole (see Figure 11).

11. When removing the heat exchanger from the heater, the end baffles of the heat exchanger (installed only on sizes 125 BTU, 175 BTU and 250 BTU) must be removed. There are two baffles covering part of the front and rear tubes of the heat exchanger. Each baffle is held in place by two screws which mount to the top of the combustion chamber wall. Remove the screws and the baffles before attempting to lift the heat exchanger out of the heater (see Figure

12).

CAUTION

It may be necessary to have help lifting the heat exchanger out and replacing it.

Figure 11. Vestibule covers.

12. Lift the heat exchanger assembly out of the heater. Reinstall heat exchanger 180 degrees (inlet/outlet header left) from it's original position.

Figure 12. Heat exchanger and end baffles.

Model LG Pool and Spa Heater

Page 15

13. After replacing the heat exchanger into the heater, the end baffles must be replaced. Each one is held in place by two screws which mount to the top of the combustion chamber wall. Reinstall the baffles on the front and rear of the heat exchanger before continuing with the "Reversible Water Connections" procedure.

14. Remove pressure switch retainer (plastic cable clamp) from the inner panel (allow pressure switch to float).

15. Reroute the pressure switch tube and thermostat bulb assembly through hole in left side of vestibule cover in reverse order.

16. Reinstall the temperature sensing bulb in the header, and fasten it with the retainer bracket and screw.

17. Reinstall the compression fitting at the end of the pressure switch tube into inlet/outlet header and tighten the fitting.

18. Route the white wiring from the high limit switches beside the heat exchanger and down to the original location following the pressure switch tubing. Secure white wires to the pressure switch tube with plastic wire ties.

27. Install plastic tie wraps on wiring in the vestibule (controls compartment).

28. Install heater door.

5.5 Connections at Heater

The heater has 2" NPT universal header cou-

plings. You can connect threaded 2" NPT iron pipe, unthreaded 1 1/2" iron or copper pipe or unthreaded 2" copper pipe using the appropriate seals included with this heater (see Figure 13). However, by installing the appropriate pipe adapters, other sizes may be used.

Plastic piping (PVC Schedule 40) can be con-

nected to the heater if local codes allow it, by using the CPVC nipples included with your heater.

To install plastic piping (see Figure 14):

1. Remove CPVC nipples from plastic bag.

2. Screw CPVC nipples into metal flange until tight, using Teflon™ tape on plastic threads.

3. Prepare the end of the pipe with the proper adapter, PVC/CPVC primer and glue. Follow the manufacturer’s instructions provided with the primer and glue for preparation procedures and curing times.

19. Connect the white wire labeled PS to the pressure switch and the other white wire to its original location on the Fireman's switch.

20. Reinstall the drain plugs and tighten securely. Replace jacket/plug grommets.

21. Install the flue collector assembly. Be sure the front and rear panels of the flue collector are installed into the grooves on the front and rear combustion chamber heat shield panels. Be sure the sheet metal panels are not pinching any wires.

22. Attach the flue collector hold down clamps to the clips located under the two center header bolts.

23. Replace the gap closures and tighten the screws securely.

24. Double-check to make sure the wiring is not pinched against sharp edges, or resting on the flue collector assembly.

25. Reinstall rainshield assembly.

26. Replace the top assembly. Make sure the tabs are outside the heater jacket. Fasten the top assembly with the hex-head screws.

Figure 13. Piping installation.

Page 16

Figure 14. Plastic piping connections.

5.6 Pressure Relief Valve

A pressure relief valve (PRV) is recommended in all installations and is mandatory in any installation in which the water flow can be shut off between the heater outlet and the pool/spa.

A pressure relief valve is not supplied with the heater. However, it may be required by local codes. The pressure rating of the valve should be at or below the lowest working pressure of any component in the filter system. Any pressure relief valve installed must comply with provisions of the Standard described in ANSI Z21.22 for the United States, or CSA 4.4 in Canada.

To install a pressure relief valve, do the following:

1. Remove the 3/4 inch (19 mm) brass plug located

on the top of the inlet/outlet header (see Figure

15).

2. Install the pressure relief valve in the threaded

hole from which the plug was removed.

3. Be sure that the exhaust port of the PRV is

plumbed so that any hot water is directed safely

away from any public areas and away from any

area occupied during servicing.

Figure 15. Thermometer and pressure relief valve.

5.7 Auxiliary Components, Chlorinators, Ozone Generators, and Sanitizing Chemicals.

The Lite2 heater is manufactured with materials

that are not compatible with high concentrations of ozone, chlorine, bromine, or other sanitizing chemicals. Heater damage caused by excessive chemicals or improper ozonization is not covered by the Water Pik Technologies warranty. Be sure to adhere to the following:

• When ozone is injected upstream of the heater, install an offgas mixing chamber, or an ozone bypass system between the heater and the ozone injector to prevent ozone and air from entering the heater.

• When chemical feeders are used, plumb the feeder downstream of the heater and install an inline check valve between the heater and the feeder (a minimum of 18" is required between the heater and the check valve).

• Never deposit chemicals directly in the pool skimmer.

SECTION 6. Electrical

WARNING

Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and dangerous operation. Verify proper operation after servicing.

Model LG Pool and Spa Heater

Page 17

6.1 Main Power

The Lite2 model LG heater does not require an external source of electrical power to operate. The power for the gas valve and safety circuit are generated by a thermopile. The thermopile generates a millivolt signal when heated by the pilot flame. Figure 17 shows the internal electrical wiring diagram and schematic of the heater.

6.2 Bonding

CAUTION

This heater must be connected to a bonding grid with a solid copper wire not smaller in diameter than 8 ga.

The National Electrical Code and most other codes require that all metallic components of a pool structure, including reinforcing steel, metal fittings and above ground equipment be bonded together with a solid copper conductor not smaller than a number 8 wire. The heater, along with pumps and other such equipment must be connected to this bonding grid. A special labeled bonding lug is provided on the right side of the heater to accommodate this requirement.

6.3 Auxiliary Time Clock Wiring

If you install a time clock to control the filter pump operation, it is recommended that the time clock have its own low voltage (Fireman’s) switch to turn off the heater before turning off the pump. The switch should shut off the heater about 15 minutes before the filter pump shuts off. This will allow for a more efficient operation by removing any residual heat contained in the heat exchanger back to the pool.

To install a time clock auxiliary switch into the heater wires (see Figure 16):

1. Remove heater door.

2. Remove the factory installed wire between

terminals 1 and 2 on the terminal strip (see

Figure 16).

The length of the wire between the heater and the time clock should not exceed 10-15 feet (4.57 m). The contact points of the time clock switch should be silver, or a low resistance alloy.

Figure 16. Time Clock Wiring.

SECTION 7. Operating Instructions

7.1 Normal Operation

The Lite2 model LG heaters are capable of automatic operation based on a call for heat at a preset temperature. The heater has an internal safety system which allows operation in a variety of conditions and prevents operation when certain adverse conditions are encountered.

When the heater's pilot is lit and the pilot generator is providing a millivolt signal to the safety circuit, water is flowing through the heater, and the temperature of the water entering the heater is below the temperature control setting, an operating cycle is initiated by the automatic control. The temperature control circuit is closed, activating the gas valve and the gas valve is opened. Gas flows through the burners, is mixed with air in the combustion chamber, and is ignited by the pilot. Operation will continue until the temperature of the water entering the heater reaches the temperature control setting.

If ignition is unsuccessful, or if the flame fails during normal operation, the temperature control circuit opens and shuts off the gas valve.

3. Connect the wires from the time clock auxiliary switch to the two terminals. Use American Wire Gage (AWG) No. 14 gauge stranded copper wire with a temperature rating of 221°F (105°C) or greater.

7.2 Start-Up

CAUTION

Do not use this heater if any part has been under water. Immediately call a qualified service technician to inspect the heater and replace any part of the control system and any gas control which has been under water.

CAUTION

Should overheating occur or the gas supply fail to shut off, turn off the manual gas control valve to the heater.

WARNING

Vent pipes, draft hoods, and heater tops get hot! These surfaces can cause serious burns. Do not touch these surfaces while the heater is in operation. Adding a vent cap reduces the temperature on the top.

WARNING

For your safety, when starting the heater, keep your head and face well away from the lower firebox opening to prevent any risk of personal injury.

CAUTION

Do not attempt repairs on the gas controls or appliance. Tampering is dangerous and voids all warranties.

CAUTION

Keep all objects off the top of the heater. Blocking air flow could damage the heater, and may void the warranty.

Be sure that there is water in the pool and that the surface level is above the skimmer or other inlet of the pool’s filter system.

Confirm that pool water is flowing normally through the pool system and equipment. With any new pool or spa installation, operate the filter pump with the heater off long enough to completely clean the water. This will remove any installation residue from the water. Clean the filter at the end of this operation before starting the heater. Start the heater in accordance with the Operating Instructions section of this manual, with particular attention to the lighting and shutdown instructions and temperature control operation.

When raising the temperature of a cold pool, remove all time clock settings. This lets the filter system and heater operate continuously until the water reaches the temperature setting on the temperature control. When that happens, the heater will automatically shut off, but the filter pump will keep running.

When the heater starts, immediately feel the outlet header of the heater to confirm that there is adequate water flow. The header should not be hot. Normally, water temperature will rise only a few degrees as it passes through the heater, and a “hot” header or pipe indicates low water flow.

Page 20

WARNING

When the heater is fired for the first time, the combustion chamber refractory binder material is driven out by the heat of the flame. White smoke and/or sharp odors may be emitted from the vent during this period. Do not inhale combustion product fumes at any time, and especially when these fumes are being emitted. This "burn-in" period will last only a few minutes.

7.3 Lighting and Shutdown Procedures

Before starting your heater, be sure that you are familiar with the setting and operation of the heater controls. Once the controls are set to your preferences, follow the instructions outlined on the following page.

Read and follow all safety instructions first.

A more detailed set of instructions of the operation of the LG controller follows in the next section.

NOTE: If your heater is configured to operate on LP gas and the LP tank runs out of fuel, turn off gas at the heater. After the tank is refilled, the heater must be relit following the instructions found on the inside of the heater. A copy of these instructions appear on the following page. DO NOT attempt repairs on the gas control or heater. Tampering is dangerous and voids all warranties.

WARNING

Do not attempt to operate the heater with the door off. Doing so may cause severe bodily injury.

Figure 18. Temperature controls.

7.4 Turning the Heater On/Off and Setting the temperature control

The temperature control (see Figure 18) is

calibrated at the factory and covers a range from approximately 70°F to 104°F (21°C to 40°C). Use an accurate pool thermometer to determine the best water temperature for your uses.

The Lite2 temperature control panel has a rocker

switch to turn the heater on and off. It also has a rotary dial to set the desired thermostat setting (see Figure

18). Once the heater has been lit by following the

safety and lighting procedures in Section 7.3, set the toggle switch on the control panel to "ON" to start the heater operation. If the heater senses that the pump is on and the thermostat setting is higher than the temperature of the pool/spa water, the pilot will ignite the main burners.

NOTE: The heater is designed to run only when the filter pump is running. If the heater does not immediately turn off when the pump turns off, turn the heater off at the control panel. The heater's pressure switch may need adjusting (see Section 7.5)

Once the pool/spa water temperature reaches

the thermostat setting, the heater will automatically stop firing. As the pool/spa water temperature falls below the thermostat setting the heater will once again start the heating cycle.

Rotate the thermostat dial clockwise to increase

the temperature setting and counterclockwise to decrease the setting. It may take several attempts to set the thermostat dial to the desired temperature. Be sure to use an accurate thermometer to measure water temperature. Once the desired temperature setting is found, loosen the screw on the Temp-Lok ring and rotate the ring until the stop rests against the knob. Tighten the screw to hold the knob in position. This will prevent accidental moving of the dial and possible overheating of the water.

DO NOT STORE OR USE GASOLINE OR OTHER FLAMMABLE VAPORS OR LIQUIDS IN THE VICINITY OF THIS OR ANY OTHER APPLIANCE. NOTE: SOME EXPOSED PARTS OF THIS HEATER MAY BE HOT WHEN OPERATING.

Page 22

Make sure the pool filter is clean before making any pressure switch adjustment. A dirty filter will restrict the water flow and the pressure switch cannot be adjusted properly. To adjust the pressure switch:

1. Set the control panel rocker switch to the OFF

position (see Figure 18).

2. Set the Pool temperature control to the Max

position.

3. Turn filter pump on. If a two-speed pump is

used, make sure it is at high speed.

Figure 19. Pressure switch adjustment.

IMPORTANT: The temperature controls

cannot be calibrated in the field. If the control is faulty, shut down the heater by following the procedures in Section 7.3 and have a qualified service technician replace the control. DO NOT use the thermostat switch to completely shut down the heater.

7.5 Water Pressure Switch Adjustment

CAUTION

The water pressure switch should be adjusted to turn the heater off when the pump is off. Setting the switch to close at too low of a flow can damage the appliance. Adjust the switch to turn the heater off, not on.

The pressure switch is preset at the factory for activation at 2 psi (14 kPa). Adjust the pressure switch only if any part of the filter system piping is 3 feet (0.91 m) or more above the top of the heater jacket.

Do not adjust the pressure switch if the heater is installed more than 15 feet (4.57 m) below or 6 feet (1.83 m) above the pool surface. Consult your local Jandy representative for recommendations.

On some installations, the piping from the heater to the pool is very short. The back pressure could be too low to trigger the pressure switch. If this happens, it may be necessary to install a directional fitting or elbows where the return line enters the pool. This will increase back pressure enough for the heater to operate properly.

NOTE: If using a two-speed pump, the heater should not be allowed to fire on low speed.

4. Set the rocker switch to ON. Heater should start.

5. Pry out the top rubber dust plug on the top of the pressure switch.

6. Use a 7/32 inch (5.55 mm) Allen wrench to turn the adjustment screw very slowly clockwise until the heater goes off (see Figure 19).

7. Slowly turn the pressure switch adjustment screw counterclockwise one-quarter turn. The heater should come back on.

8. Check the adjustment by turning the filter pump OFF. The heater should shut off immediately. If it does not, restart the filter pump and repeat Steps 6 and 7. Check the adjustment again.

9. Return the pool temperature control to the desired temperature.

7.6 Temperature Rise

The automatic flow control valve (see Section

5.2) maintains the proper flow through the heater at

rates up to approximately 125 gallons per minute (GPM) (475 liters per minute [LPM]).

A temperature rise test confirms proper water

flow through the heater. The temperature rise is the difference between the temperature of the pool or spa water before and after heating, as measured in the header. Perform the following temperature rise test when the installation is complete:

1. Make sure the pool filter is clean.

2. Set the rocker switch on the temperature control panel (see Figure 18) to OFF.

3. Turn the filter pump OFF.

4. Remove the drain plug located on the inlet/outlet header of the heater and replace it with a Pete's plug (see Figure 15).

Model LG Pool and Spa Heater

Page 23

5. Insert a pocket thermometer (see Figure 14) through the Pete's plug into the header.

6. Turn the filter pump ON and wait 3 minutes. The heater remains OFF. This allows water from the pool to reach the heater.

7. Record the temperature indicated by the thermometer (cold water).

8. Turn the heater ON following the lighting instructions found on the inside of the heater.

9. Allow the heater to run for about 3 minutes. Record the new temperature reading (heated water).

10. Subtract the first temperature reading (cold water) from the second temperature reading (heated water). The difference between the two readings is the temperature rise. The tempera- ture rise should be within the range shown in Table 6.

11. If the temperature rise is below the minimum range indicated, two possibilities arise:

a. The supply gas volume is too low. b. The system's water flow exceeds 125 GPM

(475 LPM), and requires a manual bypass valve for proper operation (see Figure 7).

12. If the temperature rise is above the maximum, there is not enough water flowing through the heater. Check for clogging in the water filter or restriction in the water pipes.

13. If the temperature rise is within the correct range, complete the procedure as follows:

a. Turn heater OFF. b. Wait 3 minutes, turn filter pump OFF. c. Remove thermometer and Pete's plug. d. Replace the drain plug.

7.7 Adjusting the Manual Bypass Valve

If a manual bypass valve is installed, use the

following procedures to adjust the bypass valve:

1. Clean pool filter.

2. Remove drain plug located on the inlet/outlet header of the heater and replace it with a Pete's plug.

3. Insert a pocket thermometer (see Figure 15) through the Pete's plug into the header.

4. Close manual bypass valve.

5. Turn on the temperature control to the OFF position.

6. Repeat steps 6 through 10 of the temperature rise test (see Section 7.6).

7. If the temperature rise is below the minimum stated in Table 6, open the manual bypass valve until temp rise climbs between the min. and max. range for your size heater. If the minimum temperature rise stated in Table 6 cannot be reached with the manual bypass fully open, then the gas supply volume is too low.

CAUTION

Operating the heater with the temperature rise above maximum or below the minimum can damage the heater and may void the warranty.

Table 6. Temperature Rise and Minimum Flow Rates

Minimum Minimum Maximum

Size GPM (LPM) °F (°C) °F (°C)

125 20 (76) 27 (15) 36 (20) 175 20 (76) 33 (19) 42 (24) 250 25 (95) 33 (19) 42 (24) 325 30 (114) 28 (16) 38 (21) 400 30 (114) 30 (17) 39 (22)

8. If the temperature rise is above the maximum, there is not enough water flowing through the heater. Check for clogging in the water filter or restriction in the water pipes.

9. Once the temperature rise is within the correct range, safety wire the handle of the manual bypass valve in place and tag the valve to prevent change in the water flow.

SECTION 8. Maintenance

8.1 Water Chemistry

The mineral content of swimming pool water

increases daily due to natural evaporation and the addition of sanitizing chemicals. If the mineral concentration in the pool gets too high, the excess minerals will deposit on the walls of the pool, in the filter system, and in the heater tubes.

Page 24

Figure 20. Heater drain locations.

The proper chemical balance in spa water is more critical than in a swimming pool heater operation. Due to the spa’s size, high water temperature and heavy usage, chemical values in a spa can vary greatly. This chemical imbalance can result in unsanitary water conditions, and affect the life of the heater.

Proper chemical balances are necessary for sanitary bathing conditions as well as ensuring your heater’s long life. Kits are available from your local pool supply dealer for making the various tests for mineral content. One of these kits will detect copper in the system. This is usually a warning that corrosion is taking place, possibly due to a low pH value combined with other chemistry problems. The condition can be corrected by changing the spa water and closely monitoring the pH factor and chemical properties of the water. Be sure to keep your chemical levels within the values indicated in Table 7.

Water Pik Technologies does not warrant heat exchangers damaged by corrosive chemical levels or excess dissolved solids in pool or spa water.

For spas, it is also necessary to perform water changes in addition to chemical treatment. It is recommended to change the spa water every 60 days for light usage and every 30 days if usage is heavy.

CAUTION

Do not operate this heater outdoors at temperatures below 20 degrees Fahrenheit (°F) (-7 degrees Celsius [°C]).

8.2.1 Spring and Fall Operation

During periods when the pool is only going to be used occasionally, turn the temperature control down to the MIN setting. This prevents the pool water from becoming chilled, and minimizes the time required to raise the pool water back up to the desired temperature.

In areas subject to only short freeze periods, turn off the heater and run the pump continuously for the length of the freeze period.

If the heater is not going to be used for a long period of time, shut it down completely. Follow the instructions found on the inside of the heater, or page 21 of this manual.

10. Inspect the external surfaces of the heat exchanger tubes for black carbon soot buildup by placing a mirror between and under the burners when the heater is firing. Remove any soot that has collected on the tubes, and correct the cause.

NOTE: After installation and first start-up, check the heat exchanger for black carbon soot buildup after the following periods of operation: 24 hours, 7 days, 30 days, 90 days, and once every 6 months thereafter.

11. Conduct a normal operating cycle and observe that the sequence proceeds as intended.

CAUTION

For your safety, when starting the heater, keep your head and face away from the burner area opening to prevent any risk of personal injury.

5. Make sure that the pressure switch operates properly by shutting the filter pump off and on a few times. The burner should go off immediately after the pump stops. An ignition sequence should start shortly after the pump is turned back on.

6. Make a visual check of the main burner flame. The flame can be seen in a mirror arrangement held beneath the burners. The flame should be a. Blue in color. b. 1 to 4 inches (25mm to 102mm) above burner

Professional Maintenance, Service and Diagnostic Trouble Shooting

WARNING

SERVICING SAFETY

Some of the servicing procedures for the Lite2 model LG pool heater are hazardous because they involve fuel gas, moving parts and procedures which require testing or temporary bypass of safety controls. For this reason, the heater must be serviced only by a qualified professional service technician.

IMPROPER SERVICE HAZARD

The Lite2 model LG pool heater incorporates unique design features. Incorrect service of this heater can result in personal injury or damage to property. To avoid such hazards, the heater must be serviced only by a qualified professional service technician.

10.1 General Information

A qualified professional technician must service the Lite2 model LG pool heater using Water Pik Technologies, Inc. service procedures. Before calling for service, however, the owner should check for obvious problems. The other components in the pool system, including pump, filters and strainers, water valves, gas supply and time clocks have an effect on heater operation.

Confirm that the LG heater control switch is set to 'ON' and that the temperature control knob is set high enough to make the heater operate. Make sure the pump is operating, that the filter and strainers are not clogged, that there are no mis-positioned water valves, that the gas is not shut off and that time clocks are properly adjusted. Also be sure that there is no blockage of the vent or louvers which supply combustion air to the burners.

10.2 Natural-Draft Combustion System

The Lite2 model LG pool heater has an atmospheric combustion system. This system is illustrated in Figure 23.

As the heated exhaust gases rise out of the combustion chamber, flow is created through the system and fresh combustion air is drawn into the heater through the louvers cut into the front and sides of the heater. Gas is forced through an orifice into the open end of a burner. When the gas flows into the burner, a “negative” pressure is created at the opening of the burner. This negative pressure pulls air into the burner with the gas and mixes the two together. As the gas/air mixture flow through the burner ports it is ignited in the combustion chamber. Hot combustion products then rise through a highly efficient heat exchanger. Combustion products then enter a flue collector and are directed to the outdoors through the grate top of the heater or a vent pipe and cap.

10.3 Heater Components and Their

Operation

1. Gas Valve / Regulator - The gas valve controls

gas flow into the manifold. It provides flow only

when the temperature controls require heat and

only if all safety controls enable operation. It is

also a positive pressure regulator. It regulates

the gas pressure in the manifold to specifications

addressed earlier in this manual. This is neces-

sary for proper operation of the burner system.

2. LG Temperature Control- The Jandy LG

controller is an electronic control which senses

water temperature by means of a thermistor and

controls heater operation to bring the water to the

desired temperature. The desired temperature is set by rotating a knob on the face of the control panel. To achieve accurate water temperatures, the pool/spa water must be monitored with an accurate pool thermometer.

3. Pilot/Pilot Ignition

The LG heater relies on a standing pilot to ignite the burners when the temperature control calls for heat. When lit the pilot receives a constant flow of gas from the gas valve. If the pilot exstinguishes, the gas valve is automatically signalled to stop the flow of gas to the pilot and the burners to prevent a gas build up in the heater. Igniting the pilot is achieved by means of a piezo spark igniter mounted on the inner front panel of the controls compartment of the heater.

4. Pilot Generator (Thermopile) - The pilot

generator is a device, that when heated by the flame of the pilot, generates a small electrical voltage of approximately 750 millivolts. The voltage is placed across the temperature controller and safety circuit of the heater. If this current is broken at any time, the gas valve is immediately shut off and the heater stops firing. This voltage is also used to activate the gas valve's pilot coil which allows gas to flow to the pilot after the gas valve knob is released.

BURNER TRAY SHELF

5. Limit Switches - Two limit switches prevent

excessive water temperature - one within the heat exchanger and one for water leaving the heater. If either senses excessive temperature, burner operation is interrupted.

6. Water Pressure Switch - This control senses

whether or not water is available to the heater by measuring back pressure inside of the heat exchanger. If the pool water pump fails or the water filter is blocked, the pressure switch prevents operation of the burner.

7. Fusible Link - This is a single-use switch which

detects abnormal temperature in the component vestibule. It is a fusible link which is held to the inner panel just above the burner tray by a sheet metal bracket. Excessive temperature in the component compartment, possibly due to a blocked flue or flame roll-out, will cause the link to fail. This opens the safety circuit which shuts off the gas valve and shuts the heater down.

10.4 Electrical Troubleshooting

This section describes procedures for checking the pilot generator and control components of the heater one at a time and in the order they appear in the control circuit.

Page 30

Note: Pump must be running during the troubleshooting procedure.

These procedures require a voltmeter with a minimum 0-1000 mVDC range. Figure 24 shows the pilot generator and control circuits, and where to take measurements. Location numbers and letters in circles have been added, and will be referenced in the following sections.

As stated at the beginning of this manual, some of these procedures are hazardous. Only a qualified service technician should service the heater.

During the trouble shooting procedure, the filter pump must be on, the pilot on the heater must be lit, the ON/OFF switch on the heater must be in the ON position and the control knob must be turned to the maximum setting so that there is a call for heat. We recommend turning the gas valve control knob to the "PILOT" position to prevent the main burners from firing throughout the procedure. Before starting the procedure, be sure that the pilot has been lit for at least 2 minutes and that the pilot generator (thermopile) is positioned correctly within the flame of the pilot.

The pilot generator also operates the pilot coil of the gas valve, allowing gas to flow to the pilot when the gas valve knob is released from the pilot lighting position (see Section 7.3 "Lighting and Shutdown Procedures"). If the pilot will not stay lit when the gas valve knob is released, check the pilot generator output as described in Section 10.4.2 and replace if necessary. If the pilot generator output is sufficient, then check the gas valve as outlined in Section 10.4.1.

10.4.1 Gas Valve

The gas valve consists of two separate internal operating valves. The main valve supplies gas to the main burners for heater operation. The pilot valve supplies gas to the pilot when the pilot generator activates the pilot coil.

If the pilot will not stay lit after following the lighting instructions in Section 7.3, check for the following:

• Pilot generator output

• Correct type of gas supplied

• Correct gas supply pressure

• Air in the gas line

• Pilot coil wire connections clean and tight

If the pilot will not stay lit after checking the items listed above, the pilot coil may be causing the fault. Replace the gas valve.

If the main burners will not light after following the lighting instructions in Section 7.3, check the voltage reading between the PP terminal on the gas

valve (test point 1) and the TH terminal on the gas valve (test point 17). If the meter shows less than 220mVDC then there is a problem with the pilot generator, the sensors in the safety loop or the control panel. Follow the trouble shooting procedure as outlined in sections 10.4.2 through 10.4.7.

If the meter shows more than 220mVDC at test

point 17, then check for the following:

• Correct type of gas supplied

• Correct gas supply pressure

• Correct gas manifold pressure

• Correct orifice size

• Air in the gas line

If the main burners will not stay lit after checking the items listed above, the gas valve may be causing the fault. Replace the gas valve.

10.4.2 Pilot Generator

The pilot generator generates a 700-750mVDC signal when heated by the pilot flame. When the pilot generator is connected to the heater's control components, there will be some voltage drop in the circuit so that the measured voltage will be less than 750mVDC. But the measured voltage should never be below 500mVDC when the ON/OFF switch is in the "OFF" position or 220mVDC when the ON/OFF switch is in the "ON" position.

With the pilot generator connected to the gas valve and the ON/OFF switch in the OFF position, place the red lead of the voltmeter on the PP terminal (test point 1) of the gas valve. Place the black lead of the meter on the PP/TH terminal (test point 2) of the gas valve. The meter should show a minimum of 500mVDC. If the meter show less than 500mV, check for partial shorts, loose or corroded connections or partially broken wires between the pilot generator and the gas valve.

If the wires and connections are sound, check the pilot generator output. Disconnect the pilot generator from the gas valve. The pilot will go out. Light the pilot while pressing down on the gas valve control knob. Continue holding the knob for at least one minute. Immediately measure the voltage between the two wires of the pilot generator. If the meter does not show at least 700mV, replace the pilot generator.

10.4.3 Fusible Link

Check the voltage going to the safety circuit. Be sure that the pilot generator is correctly wired to the gas valve, the pilot is light and the control knob on the gas valve is in the "PILOT" position. Leave the red voltmeter lead in place at test point 1. Touch the black lead of the meter to the terminal of the fusible link where the white wire from the gas valve is connected (test point 3).

Model LG Pool and Spa Heater

Page 31

If no voltage is detected at test point 3, the wire between the gas valve and the fusible link is broken. Replace the wire.

If there is a minimum of 220mV at test point 3, move the black meter lead to the other terminal of the fusible link (test point 4).

If no voltage is detected at test point 4, the fusible link has failed. This indicates higher than normal temperatures in the component compartment (vestibule). Normal component compartment temperature is well below 300

F. The fusible link is designed to fail at temperatures above 305°F. Excessive temperature might be due to a blocked flue or heat exchanger. Clean the heat exchanger and clear the flue and vent of any restrictions. Sometimes the fusible link fails due to flame roll-out. Flame roll-out may be caused by delayed ignition or downdrafting in windy areas. Thoroughly investigate the causes for flame roll-out and correct the problem when replacing the fusible link.

10.4.4 Fireman Switch and External Interlocks

Check the voltage going to the external device. Touch the black lead of the meter to the fireman switch terminal strip where the white wire from the fusible link is connected (test point 5). The meter should read at least 220mV. If the voltage is less than 220mV, there may be a bad connection or wire between the fusible link and the terminal strip. The wire may need to be replaced. If voltage of 220mV or more is detected at test point 5, move the black lead of the meter to the fireman switch terminal strip connection where the white wire from the high limit is connected (test point 6). The meter should read at least 220mV. If there is no voltage, the time clock switch or other external interlock may be mis-adjusted, misconnected or defective. Correct this external problem.

10.4.5 Limit Switches

Since the limit switches are not easily accessible, you can check the voltage going into the component after the limit switches in the circuit. If voltage is detected there, then the limit switches are closed and are operational.

Check the voltage going to the water pressure switch. Leave the red voltmeter lead in place at test point 1. Touch the black lead of the meter to the terminal of the water pressure switch where the white wire is connected (test point 11).

If the voltage is less than 220mV, there may be a bad connection, a partial short or a faulty sensor. If there is no voltage, one of the limit switches is open. This is normally due to excessive water temperature, which should be thoroughly investigated before

replacement of limit switches. Excessive water temperature may be caused by low water flow. Water flow deficiency may be due to obvious problems such as a defective pump or blocked water filter. Alternatively, excessive water temperature may be due to over-firing, or to a problem with the water piping or the heater's internal bypass control. Over-firing might be a result of an incorrect gas orifice or supply of propane gas to a heater intended for natural gas.

If there are no such fundamental problems, identify which of the switches is open. Limit switch access is through the limit switch cover on the inlet/ outlet header. Remove the cover and retainer bracket from the high limit switches and remove the limit switches from the wells. Move the black lead of the meter to the terminal on the 150°F limit switch (test point 7) that is connected to the fireman switch terminal block. Less than 220mV at this point means that the wire between the terminal block and the limit switch has a poor or broken connection or a partial short. Replace the wire assembly. If at least 220mV is detected at test point 7, then move the black lead of the meter to the other terminal of the 150°F limit switch (test point 8). Low or no voltage here means that the limit is open and must be replaced.

If 220mV or more is detected at test point 8, move the black lead of the meter to the terminal on the 135°F limit switch (test point 9) that is connected to the 150°F limit switch. Less than 220mV at this point means that the wire between the two limit switches has a poor or broken connection or a partial short. Replace the wire assembly. If at least 220mV is detected at test point 9, then move the black lead of the meter to the other terminal of the 135°F limit switch (test point

10). Low or no voltage here means that the limit is open and must be replaced. If voltage is detected at test point 10, move the black lead of the meter to the terminal of the water pressure switch where the white wire from the high limits is connected (test point 11). Less than 220mV at this point indicates that the wire connecting the high limits to the water pressure switch is faulty or poorly connected. Correct the problem or replace the wire.

Note: The limit switches have different trip points, and it is important that replacements are correct. The 150°F switch has a red dot on the top of the brass fitting, and must be installed in the lower (horizontal) well in the header. The 135°F switch has no dot and must be installed in the upper (vertical) well in the header.

10.4.6 Water Pressure Switch

If the meter shows at least a 220mV signal at test point 11, move the black lead of the meter to the other terminal on the water pressure switch (test point 12).

If there is no voltage, the pressure switch contacts are open. This is almost always due to a water flow deficiency, the most common one being a blocked water filter or defective pump. However, sometimes it is due to blockage of the copper siphon loop tube or mis-adjustment of the switch. Investigate thoroughly, referring to Section 7.5 on “Water Pressure Switch Adjustment”. If there is no problem with the pool system or pressure switch adjustment, replace the pressure switch.

10.4.7 Temperature Control Circuit

The temperature control circuit consists of four major components which must all be working correctly for the signal to be transmitted to the gas valve. The four components are the ON/OFF toggle switch, the variable temperature control (potentiometer), the temperature sensor (thermistor) and the temperature control board. Use the following procedure to check each component for functionality.

Check the temperature control as a complete circuit before checking each component individually. With the red lead of the meter still at test point 1, place the black lead of the meter on the TH terminal of the temperature control circuit board (test point 16). If the meter shows more than 220mV at the pressure switch (test point 12) but not at test point 16, then one of the components of the temperature control circuit is faulty. Proceed with the following sections to test the components.

10.4.7.1 ON/OFF Toggle Switch

Remove the temperature control panel from the bezel on the front of the heater to gain access to the switch. Be sure that the toggle switch is in the "ON" position. Place the black lead of the meter on the toggle switch terminal (test point 13) that is connected to the pressure switch. Less than 220mV at this point indicates that there is a problem with the black wire that connects the pressure switch to the toggle switch. If at least 220mV is detected at test point 13, move the black meter lead to the other terminal on the toggle switch (test point 14). A reading of less than 220mV here indicates a faulty switch. If the reading is more than 500mV, turn the switch "OFF" and then "ON" again to be sure that the internal contacts are working correctly. The volt meter reading should drop to zero when the switch is "OFF" and return to at least 220mV when the switch is placed back in the "ON" position.

10.4.7.2 Variable Temperature Control

The variable temperature control is a 0-10,000 ohm variable resistor. Set your ohmmeter to the 0-20K

range. Remove the temperature control wires from the control circuit board. Place one lead of the meter on each of the wires (test points 18 & 19). With the control set to MIN the meter should read near 10,000 ohms. Now turn the control to the MAX position. The meter should read close to zero. If the meter shows an open circuit, or readings outside of the range stated above, replace the controller. If the control is working correctly, reconnect the wires to the circuit board.

10.4.7.3 Temperature Sensor

The temperature sensor is a 0-20,000 ohm thermistor. Set your ohmmeter to the 0-20K range. The meter readings will depend on the temperature of the water in the header. See the chart below for approximate readings at various temperatures.

To test the temperature sensor, circulate water through the heater for 5 minutes. Remove the temperature sensor wires from the temperature control board. Place one lead of the meter on each wire of the temperature sensor (test points 20 & 21). Record the reading. Measure and record the water temperature of

the pool near the inlet of the filter system. Find the temperature in the chart that is closest to your temperature reading of the pool water. Compare your ohmmeter reading to the resistance number in the chart. Remember that this is an approximate reading and numbers may vary. If your reading is close to the numbers indicated in the chart then the temperature sensor is working correctly. Reconnect the wires to the circuit board. If your reading is vastly different or outside of the ranges shown the temperature sensor should be replaced.

10.4.7.4 Temperature Control Circuit Board

With the red lead of the meter still at test point 1, place the black lead of the meter on the TH/PP terminal of the temperature control circuit board (test point

15). If there is more than 220mVDC at this point but not at the TH terminal of the temperature control circuit board (test point 16) as tested in section 10.4.7, then the control circuit board is faulty. Replace the board.
