The flame should be blue with a well-defined pattern.

4" MAX

MAIN BURNER FLAME

Fig. # 8144.1

1. Spa or hot tub water temperatures should never exceed 104°F (40°C). A temperature of 100°F (38°C) is considered safe for a healthy adult. Special caution is suggested for young children.

2. 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.

Pregnant women beware!

102° F (39°C) can cause fetal damage during the first three months of pregnancy, (resulting in the birth of a brain damaged or deformed child). Pregnant women should stick to the 100°F (38°C) maximum rule.

4. Before entering the spa or hot tub, users should check the water temperature with an accurate thermometer; spa or hot tub thermostats may err in regulating water temperatures by as much as four degrees Fahrenheit (2.2°C).

5. Persons with a medical history of heart disease, circulatory problems, diabetes, or blood pressure problems should obtain a physician's advice before using pools or hot tubs.

6. Persons taking medications which induce drowsiness, such as tranquilizers, antihistamines, or anticoagulants, should not use spas or hot tubs.

Soaking in water over

Fig. # 8958

PILOT BURNER FLAME

A yellow or "floating" flame indicates restricted air openings or incorrect orifice size. Should this occur, shut the heater off and contact your installer or gas supplier.

WATER PRESSURE SWITCH

A water pressure switch is provided in the heater to shut off the burners in the event that water supply to the heater is interrupted. It is very important to verify that the switch electrically opens and shuts off the gas valve when water flow to the heater is interrupted. Otherwise, rapid and severe damage will likely occur to the heater. (The water pressure switch should be checked and adjusted for proper operation by a qualified service person at the time of installation and periodically checked thereafter. Refer to pressure switch servicing instruction in Section 4 of this manual.)

WARNING:

Operation of the heater without water circulation will cause rapid and severe damage to the heater.

SECTION 3 / MAINTENANCE AND CARE PROCEDURES

To be followed one month after start-up and then

semi-annually.

1. Inspect top of heater and draft hood for soot, (a sticky black substance around finned tubes, baffle and open flue gas passageways).

CAUTION:

surfaces completely prior to cleaning. Do not use steel wire brush.

2. Clean main burners and pilot burner of dust and lint.

3. Inspect and operate all controls, gas valve and pressure relief valve.

Soot may be combustible. Wet sooted

Page 7

4. Make visual check of the burner and pilot flame. Flame pattern on the main burner and pilot is indicated in the previous illustration. Yellow flame means restriction of the air openings. Lifting or blowing flame indicates high gas pressure. Low flame means low gas pressure. Should this occur, shut the heater off and contact your gas supplier or qualified service agency.

5. On indoor heaters, clean room intake openings to assure adequate flow of combustion and ventilation air.

CAUTION:

Combustion air must not be contaminated corrosive chemical fumes which can damage the heater.

6. Keep area around heater clear and free from

combustible materials and other flammable and corrosive vapors and liquids.

BASIC TIPS IF HEATER WILL NOT FIRE:

1. If you have no electrical power; it may be your "circuit breakers" have tripped. Try re-setting them.

2. if you have electrical power but the heater will not fire

check the following:

3. The time clock must be moved to the "ON" position.

4. Your pump strainer basket may be full. If so remove debris.

5. your filter may be dirty. If so, backwash or clean filter. (To tell if your filter is dirty, the gauge pressure will be higher than usual).

6. The pump amy have lost it's prime. It may be running dry, check the pressure gauge on the filter. If there is no pressure; then you are not moving water (or your gauge is broken). Try to get the pump to run at it's normal flow rate.

COLD WEATHER OPERATION MODERATE CLIMATE: Heater operation can con-

tinue during short term cold spells. When temperatures are below freezing, flow (continuous pump operation) must be maintained.

CAUTION: Do not use the heater to maintain water temperatures just above freezing or for freeze protection. When heaters are used during freezing weather care must be taken to avoid freeze ups. Continuous pump operation is a must. Additional protection may be required. The heater is not warranted against freeze ups.

COLD CLIMATE: Prolonged operation with water temperatures below 50°F is not recommended. When starting the heater with pool temperatures below 50°F, operate the heater continuously until higher temperatures are reached. Operating the heater for prolonged periods with pool water below 50° can seriously damage the heater, and is not covered by the warranty.

For cold climate areas please follow the winterizing procedures listed below.

WINTERIZING THE SPA HEATER

When heaters installed outdoors in freezing climate areas are to be shut down for the winter, observe the following step-by-step procedure:

1. Turn off gas valve, manual gas valve, and electrical supply to the heater.

2. Open drain cock located on the inlet/outlet header, (under water pipes). Remove drain changer inspection panels on the side opposite water piping to gain access to the plug on the return header.

POOL & SPA WATER CHEMISTRY

Chemical imbalance can cause severe damage to your heater and associated equipment. Maintain your water pH between 7.4 and 7.8 and total alkalinity between 100 and 150 p.p.m. If the mineral content and dissolved solids in the water become too high, scale forms inside the heat exchanger tubes, reducing heater efficiency and also damaging the heater. If the pH drops below 7.2, the heater will be severely damaged. This will result in corrosion of the heat exchanger. Heat exchanger damage resulting from

chemical imbalance is not covered by the warranty.

Vent piping the same size or larger than the draft hood outlet is recommended, however, when the total vent height is at least ten (10) feet (draft hood relief opening to vent terminal), the vent pipe size may be reduced as specified in Part 11 of the National Fuel Gas Code, ANSI Z 223.1. As much as possible avoid horizontal runs of vent pipe and too many elbows. If installation requires horizontal runs, the vent pipe must have a minimum of 1/4 inch per foot rise and should be supported at not less than five foot intervals. Plumbers tape, crisscrossed, will serve to space both horizontal and vertical piping. Gas vents supported only by the flashing and extending above the roof more than five feet should be securely guyed or braced to withstand snow and wind loads. We recommend use of insulated vent pipe spacer through the roofs and walls.

For protection against rain or blockage by snow, the vent pipe must terminate with a vent cap which complies with the local codes or, in the absence of such codes, to the latest edition of the National Fuel Gas Code, ANSI

Z223.1.

The discharge opening must be a minimum of two feet vertically from the roof surface and at least two feet higher than any part of the building within ten feet. Vent stack shall be at least five feet in vertical height above the draft hood outlet. The vent cap location shall have a minimum clearance of 4 feet horizontally from, and in no case above or below, unless a 4-foot horizontal distance is maintained, from electric meters, gas meters regulators and relief equipment.

The weight of the vent stack or chimney must not rest on heater draft hood. Support must be provided in compliance with applicable codes. The heater top and draft hood must be readily removable for maintenance and inspection. Vent pipe should be adequately supported to maintain proper clearances from supported to maintain proper clearances from combustible construction.

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 Flue Gas Code ANSI Z 223.1.

PLUMBING FOR WATER CONNECTIONS

LOCATION

The VERSA heater requires water flow and positive pressure to fire and operate properly. It must therefore be installed downstream of the discharge side of the filter pump. A typical installation is plumbed as follows:

1. The inlet side of the filter is plumbed directly to the discharge side of the filter pump;

2. The outlet side of the filter is then plumbed to the inlet of the heater; and

3. The outlet of the heater is plumbed to the return line to the pool or spa. The pump, filter and heater are thus plumbed in series.

Plumbing from the heater back to the pool must not have any valves or restriction that could prevent flow when the pump is operating. To do so will void the warranty.

FLOW RATES

MIN.GPM: 20, MAX.GPM: 115*

*When flow rates exceed 115 GPM an external auxiliary bypass valve is required. See External auxiliary bypass valve section for details.

NOTE: High chemical concentration from feeders and chlorinators that are out of adjustment will cause very rapid corrosion to the heat exchanger in the heaters. Such damage is not covered under the warranty.

INTERNAL AUTOMATIC BY-PASS VALVE

A built-in automatic by-pass valve is provided in the in/out header. The internal by-pass valve automatically responds to changes in water pressure in the piping system. Proper amount of water flow is maintained through the heater under varying pressures dictated by the conditions of the pump and filter.

Fig. # 8078.0

CAST IRON HEADER

The inlet/outlet header accepts a 1-1/2" pipe thread. The header will accept either copper and galvanized pipe or CPVC adapters.

CAUTION: Never install PVC directly in header flanges. The initial connection must be made with a higher temperature material such as CPVC or Copper. PVC may be utilized immediately after the initial connection.

AUTOMATIC CHLORINATORS AND CHEMICAL FEEDERS

All chemicals must be introduced and completely diluted into the pool or spa water before being circulated through the heater. Do not place chlorine tablets or bromine sticks in the skimmer. High chemical concentrations will result when the pump is not running (i.e. overnight).

Chlorinators must feed downstream of the heater and have an anti-siphoning device to prevent chemical backup into the heater when the pump is shut off.

EXTERNAL AUXILIARY BYPASS VALVE

(Where required)

An auxiliary bypass valve should be used when flow rates exceed 115 GPM (usually a high performance pump size larger than 2 HP will exceed this flow rate). This valve is required to complement the function of the automatic bypass valve, particularly when starting the heater in winter or early spring when the spa or pool temperature is down below 55°F. It also serves to eliminate needless pressure drop through the heater and accompanying reduction in the flow rate to the spa jets, etcetera.

PRESSURE SWITCH

The pressure switch, or heater actuator, insures that the heater operates only when the filter pump is in operation. It is factory set at 1.75 PSI for deck level installations. When the heater is located below the level of the spa or pool, it may be necessary to reset the pressure switch to compensate for the no-flow static head. If it is necessary to reset the pressure switch, we recommend the following procedure: see next page please.

NOTE:

If heater is installed outside of the limits shown, a flow switch must be used in place of the pressure switch when mounted and wired adjacent to the heater.

TWO SPEED PUMPS

In some cases, the flow on the low-speed is insufficient to operate the heater. This is apparent when the pressure switch cannot be further adjusted or if the heater makes banging noises. In these cases, the pump must be run at high speed when heating the water.

CAUTION:

Do not operate the heater without the func-

tion of a properly adjusted pressure switch.

1. Shut off main electrical power switch to heater.

2. Remove inspection panel.

3. Remove defective high limit and replace with a new high limit.

4. Replace inspection panel.

PILOT SAFETY

PILOT SAFETY (Millivolt System)

The heaters equipped with the standing pilot (millivolt

system), have pilot generators which act as a safety device to shut off the flow of gas to the main burners and the pilot burner in case the pilot flame is extinguished. The pilot burner must be manually relighted to place the heater in operation again. Refer to the lighting instructions provided on the heater label.

PILOT SAFETY (IID Units) ELECTRIC IGNITION

The heater employs a pilot safety which closes the

main gas valve within 8/10ths of a second whenever the pilot flame is interrupted. Pilot flame is automatically lit when the device is powered. Unit performs its own safety check and opens the main valve only after the pilot is proven to be lit.

Extension Pieces (2) Auger with Carbide Tip Wire Brush

TUBE CLEANING PROCEDURE

Establish a regular inspection schedule, frequency depending on local water condition and severity of service. Do not let the tubes clog up solidly. Clean out deposits over 1/16" in thickness.

The heater may be cleaned from the return header side, without breaking pipe connections. It is preferable, however, to remove both headers for better visibility through the tubes and to be sure the ground-up lime dust does not get into the system.

Note that you do not remove the top panel or the heat exchanger, generally.

After reaming, mount the wire brush in place of the auger and clean out debris remaining in the tubes.

Another method is to remove the heat exchanger, ream tubes and immerse heat exchanger in non-inhibited de-scale solvent for severe scale build-up.

outside each tube sheet. A loose tube will sometimes pull toward the roller. Attach drill motor to tube roller, holding it straight and level. Proceed to expand tube until the tool begins to grab. At this point, 1/2" to 1" should be exposed on the tool shank. Reverse drill motor or wrench out by hand. Care should be exercised to avoid applying excessive torque during rolling operation and to avoid thinning out any part of the tube wall excessively over .015". Use same procedure at the opposite end of the tube.

Apply line pressure test, and re-roll, if necessary

before re-assembly of the heater.

DESOOTING PROCEDURE

CAUTION:

EXTREME CARE. NEVER USE A WIRE BRUSH.

SOOT IS COMBUSTIBLE. EXERCISE

Fig. # 8154.0

TUBE REPLACEMENT PROCEDURE

On Raypak units, tube replacement may be effected without rolling, as a temporary means of repair, providing there are two or more tubes rolled in to act as stays on the left and right sides. The "O" rings should provide a seal up to 125 PSI working pressure. Use 3/ 8" heavy duty reversible drill motor or large to power the tube roller. If a reversible drill is not available, after rolling the tube in, remove the drill motor and wrench out the roller. A tube roller is available from the factory.

Shut gas and power off to the unit, close the system off and drain the heater. Remove the draft diverter. Remove the access panel and jacket top. Lift flue collector off. Remove "V" baffles over tube(s) to be replaced. If no pipe unions have been provided, use the header as a union, remove the flange nuts off the inletoutlet header, break gas connection and slide heater away from piping to allow room to work. Pull wedge clips out of control wells and remove sensing bulbs. Remove flange nuts of the return header and remove header. Lift heat exchanger straight up and inspect "O" ring seals at this time. Unless severed they are reusable. The tube may be cut out the a hacksaw or hammer and chisel adjacent to both tube sheets, leaving studs in the tube sheets. Then proceed to collapse studs in the tube sheets with a chisel or screwdriver. Use caution not to cut into the tube sheet. Replacement tubes will have the fins stripped off longer on one end. The long end is inserted into the opening of the tube sheet first; then the short end is fitted through the opposite tube sheet. If the tube ends become dented or bent, straighten at least (4) inches back from the tube and by means of a tapered punch.

Insert tube roller into tube opening up to stop against tube, then push center rod in until roller is tight. Be careful to keep replacement tube squared up 1/8"

Soot can clog areas between fins and cause eventual tube failure. Any sign of soot at the base of the burners or around the outer jacket indicates a need for cleaning.

1. Disconnect top portion of unit. (See heat

exchanger

removal procedure steps 1 through 6).

2. Remove burner tray (See burner tray removal

procedure.)

3. Take a garden hose and wash heat exchanger,

making sure soot is removed completely from be-

tween fins. Avoid excessive water against refrac-

tory.

NOTE:

In extreme cases it may be necessary to remove the heat exchanger completely for cleaning. The simplest method is steam cleaning at the local car wash. DO NOT WIRE BRUSH.

COMBUSTION CHAMBER REMOVAL

1. Remove heat exchanger (See heat exchanger

removal procedure).

2. Lift up and remove front and rear refractory shield.

3. Remove refractory panels.

4. Reverse above procedure to re-install.
