INSTALLATION REQUIREMENTS

The installation must conform to the requirements of the authority having jurisdiction or, in the absence of such requirements, to the National Fuel Gas Code, ANSI Z223.1latest edition.

This installation must also conform to the additional requirements in this Slant/Fin Instruction Book.

NATURAL GAS-FIRED BOILER LOCATION

Provide a level, solid foundation for the boiler. Location should be as near as possible to chimney or outside wall so that the flue pipe from boiler is short and direct. (See Appendix A for vent terminal location restrictions.) The location should also be such that all boiler components are protected from water (dripping, spraying, rain, etc.) during appliance operation and service (circulator replacement, control replacement, etc.).

WARNING LIQUEFIED PETROLEUM (L.P.) PROPANE GAS-FIRED BOILER LOCATION

REQUIRES SPECIAL ATTENTION Liquefied Petroleum (L.P.) propane gas is heavier than air. Therefore, propane boilers, piping, valves should NOT be installed in locations where propane leaking from defective equipment and piping will "pool" in a basement or other space below the leak.

A spark or flame from the boiler or other source may ignite the accumulated propane gas causing an explosion or fire. Provide a level, solid foundation for the boiler. Location should be as near the chimney as possible so that the flue pipe from boiler to chimney is short and direct.

The UNIFORM MECHANICAL CODE ma y be in effect in your geographic area.

The following precautions are cited by the 1994 UNIFORM MECHANICAL CODE, section 304.6:

"LPG Appliances. Liquefied petroleum gas-burning appliances shall not be installed in a pit, basement or similar location where heavier-than-air-gas might collect. Appliances so fueled shall not be installed in an abovegrade under-floor space or basement unless such location is provided with an approved means for removal of

unburned gas." Consult Chapter 5 of the 1994 UNIFORM MECHANICAL CODE for design criteria of the "approved" means for removal of unburned gas.

MINIMUM CLEARANCES FROM COMBUSTIBLE CONSTRUCTIONS

A. Minimum clearances to the exterior surfaces of the boiler

shall be as follows: MINIMUM ALCOVE AND CLOSET CLEARANCE

For Combustible Recommended Surface Front 6" 18" Rear 0" 0" Left Side 0" 5" Right Side 0" 5" Top 5" 18" Flue Connector:

Enclosed — 2" 6" Uninclosed — 1" 6"

B. Provide accessibility clearance of 8" on sides requiring

servicing and 18" on sides used for passage.

C. All minimum clearances shown above must be met. This

may result in increased values of some minimum clearances in order to maintain the minimum clearances of others.

D. Clearance from hot water pipes shall be 1 inch**.

** At points where hot water pipes emerge from a floor, wall or ceiling,

the clearance at the opening through the finished floor boards or wall or ceiling boards may be not less than 1/2 inch. Each such opening shall be covered with a plate of uncombustible material.

Construction for Service

VENTING APPLICATION

The Lynx LX-85 is a sealed combustion type boiler, it may be installed and vented either as a direct vent boiler which all air for combustion is obtained directly from outside or as a non-direct vent boiler which air for combustion is taken from inside the boiler room.

The Lynx LX-85 boiler must be vented by 3" diameter PVC/CPVC schedule 40 pipe, or the proper 3” diameter stainless steel venting system (see “vent material” on page 6) through the roof or sidewall. An optional adapter is available for connecting stainless steel venting to the boiler vent outlet. See the Lynx LX-85 Parts List, publication # LX-10PL.

BOILER ROOM AIR SUPPLY AND VENTILATION

An ample supply of air is required for combustion and ventilation. When buildings are insulated, caulked and weather-stripped, now or later on, direct openings to outside may be required and should be provided. If the boiler is not near an outside wall, air may be ducted to it from outside wall openings.

Provisions for combustion and ventilation air must be made in accordance with section 5.3, Air for Combustion and Ventilation, of the National Fuel Gas Code, ANSI Z223.1-latest edition, or applicable provisions of the local building codes. The following recommendation applies to buildings of energy-saving construction, fully caulked and weatherstripped.

INSTALLATION IN ENCLOSED BOILER ROOM REQUIRES TWOUNOBSTRUCTED OPENINGS FOR PASSAGE OF AIR INTO THE BOILER

ROOM.

ADDITIONAL REQUIREMENTS FOR THE COMMONWEALTH OF MASSACHUSETTS

4. Air drawn from inside the building; one opening near the floor and one opening near the ceiling, each opening with a minimum FREE air passage area of 1 square inch per 1000 Btuh of total appliances’ input.

IF BOILERS ARE INSTALLED ADJACENT TO OTHER FUEL BURNING EQUIPMENT, THE AREA OF FREE OPENINGS MUST BE APPROPRIATELY INCREASED TO ACCOMMODATE THE ADDITIONAL LOAD.

B. DIRECT VENT INSTALLATION

Adequate air supply should be provided to prevent overheating of the boiler controls and boiler room. Openings for passage of air into the boiler room for direct-vent installation must be at least

⁄2 of the openings required for the non-direct vent as mentioned above.

If additional non-direct vent appliances are installed in the same space and adequate air openings are provided for them, there are no additional air openings required for the Lynx LX-85.

For both direct and non-direct installation, the following must be considered:

- Openings must never be reduced or closed. If doors or

windows are used for air supply, they must be locked open.

- Protect against closure of openings by snow and debris.

Inspect frequently.

- No mechanical draft exhaust or supply fans are to be

used in or near the boiler area.

- Boiler area must never be under negative pressure. The

flow of combustion and ventilating air to the boiler must not be obstructed.

VENT AND AIR INTAKE MATERIALS

The vent piping for direct or non-direct vent installation must be 3” diameter PVC/CPVC schedule 40 pipe, or UL listed single wall 3” diameter AL29-4C* stainless steel material. The air intake piping for direct vent installation must be 3" diameter PVC/CPVC schedule 40 pipe. The following manufacturers’ systems are approved for use within a specified minimum and maximum equivalent vent length in this manual.

Sealant

When joining the various components of the listed stainless steel vent systems, the manufacturers’ instructions should be closely followed to insure proper sealing. Use sealant specified by vent system manufacturer for sealing of pipe and fittings, if required. When joining the PVC/CPVC pipe and fittings, follow the instructions provided in this manual. All connections must be liquid and pressure tight. DO NOT use galvanized flue pipe or any plastic-type materials other than PVC/CPVC Schedule 40.

The vent and air intake connections on the boiler are designed to accommodate either PVC/CPVC Schedule 40 pipe or the listed stainless steel vent systems (by inserting the optional adapter specified in the Lynx LX-85 Parts List, publication # LX-10PL, for stainless steel venting). Built-in sealing rings are provided, so no additional sealant is required. The application of liquid soap to the outer end of the vent pipe (or adapter, if used) will aid in installing it. Make sure the pipes are round and burr-free, and push down into the appropriate step of the connector or adapter, until snug. (See Figure 5).

FLUE GAS VENTING REQUIREMENTS

The Lynx LX-85 series boiler is a high efficiency, mechanically forced draft boiler and, therefore, requires different venting arrangements than natural draft, lower efficiency boilers.

THE FOLLOWING INSTRUCTIONS MUST BE CAREFULLY READ AND FOLLOWED IN ORDER TO AVOID ANY HAZARDOUS CONDITIONS DUE TO IMPROPER INSTALLATION OF THE AIR INTAKE AND FLUE GAS VENTING SYSTEM.

The vent piping installation MUST be in accordance with these instructions and with ANSI Z223.1-latest edition NATIONAL FUEL GAS CODE, Part 7, Venting of Equipment. Other local codes may also apply and must be followed. Where there is a conflict between these requirements, the more stringent case shall apply. The use of a vent damper is NOT permitted on this boiler series.

PVC/CPVC PIPE GENERAL ASSEMBLY METHOD

The following are the recommended methods for cutting, cleaning and connecting PVC and CPVC pipe, for both the vent and air intake piping system:

1. When laying out the piping system, work from the boiler

vent and air intake adapter to the point of outside termination.

2. Cut the PVC/CPVC pipe to the required lengths, and

pre-assemble the entire system, before sealing. Disassembly after sealing, to make any corrections, will not be possible.

3. Once the pre-assembled PVC/CPVC pipe vent and air

intake system is verified to be of the proper length pipe and fitting orientation, begin disassembling and preparing the pipes and fittings for the sealing process. This can be done section by section, or the complete vent and air intake system can be disassembled. It is recommended to mark the various parts, before complete disassembly, to eliminate the possibility of errors during re-assembly.

4. De-burr the inside and outside of every PVC/CPVC pipe, to

ensure that they engage fully into the fittings, and flow is not compromised. A small chamfer on the outside of each pipe can particularly aid in the final assembly process.

5. Wipe or knock out any debris from inside the PVC or

CPVC pipe, which may have accumulated there from the cutting process or storage. Debris can cause operational problems with the boiler combustion components.

6. Thoroughly clean the outside ends of each pipe, and the

inside of each fitting. The surfaces must be dry for the sealing agents to work properly. Handle the prepared pipe lengths away from the cleaned ends, and handle the cleaned fittings, from the outside, to avoid contamination.

7. Re-assembly of the PVC or CPVC pipe should be done in

sections, to avoid the primer and cement drying before the parts are engaged.

8. For each joint, first apply a coat of primer to the outside

sealing surface of the pipe and the inside sealing surface of each fitting. Use only the primer type that is specified for either the PVC or CPVC pipe that is bing utilized.

9. Before the primer dries, apply a coat of cement over it. A

second coat of cement can be applied, if necessary, but must be done quickly and in a manner that avoids unnecessary build-up that would cause obstruction inside the system. Use only the cement type that is specified for either the PVC or CPVC pipe that is being utilized.

10. Before the cement dries, insert the pipe into the fitting. A

slight twisting motion while pushing the pipe into the fitting will aid in distributing the cement evenly and ensuring the parts fully engage.

11. Quickly wipe the excess cement from the outside areas of

the joint. Discard any rags used to avoid later getting the cement on hands, clothes and equipment.

VENT AND AIR INTAKE RESTRICTIONS

1. Maximum allowed equivalent vent and air intake length for

all of the approved vent and air intake materials is 100 equivalent feet.

2. Equivalent of vent or air intake length is sum of the

straight pipe lengths and equivalent length of elbows as shown in the table on this page.

Figure 6.

3. The vent termination is in addition to the allowed equivalent lengths.

4. Minimum vent length is 2 feet of straight pipe, plus one 90˚ elbow that is required.

5. Vent length restriction is for both direct and non-direct vent installations.

EXAMPLE: Boiler model LX-85 is to be installed. The combustion air is provided by air intake piping directly to the boiler (direct-vent installation). The vent piping will be PVC and installation location will require the use of 4 elbows for the vent to run the termination. The air intake piping will also be PVC, and also will require the use of 4 elbows.

In this case, the maximum straight pipe vent length that can be utilized with the 4 elbows would be: 100’ - (4’ x 5’) = 80’. Since the air intake pipe also is PVC and requires the use of 4 elbows, the maximum straight pipe air intake length that can be utilized is also 80 feet.

If the air for combustion were taken from the boiler room (non-direct vent installation), still the maximum straight vent length would be 80 feet.

6. The LX-85 boiler is equipped with a built-in condensation drain and trap. The trap must be filled with water. DO NOT operate the boiler without filling the trap with water to prevent flue gas discharge into space. The drain must dispose of possibly large quantities of condensate, which may require a neutralizing system. Refer to the “Condensate Drainage” section of this manual. No additional condensation drain and trap is required on the vent piping system itself.

7. The horizontal vent pipe must be sloped upward from the boiler at a pitch of at least 1/4” per 1 foot of run, so that the condensate from the vent system runs to the boiler vent adapter pipe, then out the built-in condensation drain and trap.

8. The horizontal vent and air intake pipes must be supported

with pipe straps, at intervals no greater than 5 feet, when PVC/CPVC pipe is utilized. This support spacing applies also to stainless steel vent pipe, unless the manufacturer’s instructions permit otherwise. The vertical vent and air intake pipes also must be supported, wherever the building construction provides allowance for it, such as ceiling or roof passage openings where a firestop and support or braces can be affixed.

9. Minimum clearances of vent pipes from combustible

constructions must be maintained (see Page 4). No clearance is required between the vent and air intake pipes of this boiler.

10. Common venting with other appliances or another Lynx

boiler is not allowed.

VENT TERMINATION LOCATION AND CLEARANCES

1. The venting system shall terminate at least 3 feet above any forced air inlet located within 10 feet.

2. The venting system shall terminate at least 4 feet below, 4 feet horizontally from, or 1 foot above any door, window or gravity air inlet into any building. The bottom of the vent terminal or air intake terminal shall be at least 12 inches above grade or the normal snow level whichever is greater.

3. Through the wall vents shall not terminate over public walkways or over areas where condensate or vapor could create a nuisance or hazard or could be detrimental to the operation of regulators, relief valves or other equipment. Minimum clearance of 4 feet horizontal distance is maintained, from electric meters, gas meters, regulators and relief equipment.

4. Vent termination must not be located in any confined space (i.e. window wells, alcoves, narrow alleys) or under any overhang or deck. Vent termination should not allow flue gas discharge towards neighbor’s windows or where personal injury or property damages can occur.

B. NON-DIRECT VENT - VERTICAL VENTING

Figure 9 shows typical venting through the roof. The vent pipe must pass through the ceiling, floor and the roof vertically through a 6" minimum diameter cutout. A fire stop is required for each ceiling and floor penetration. For roof passage, an appropriate UL listed roof flashing must be used.

11. DO NOT install a vent damper or similar devices in vent system or on the boiler.

12. DO NOT insulate venting system.

VENTING INSTALLATION

Only the approved PVC/CPVC and stainless steel materials listed on page 6 may be used for the venting system installation. If stainless steel vent systems are used, follow the manufacturer’s instructions, in conjunction with these instructions.

I. NON-DIRECT VENT INSTALLATION

The air for combustion is taken from the ambient air surrounding the boiler; therefore, ample supply of air is required for combustion and ventilation (see page 6.)

DO NOT use this installation method if the surrounding of the boiler is contaminated. See page 5 for the list of harmful contaminants and their sources, to avoid.

A. NON-DIRECT VENT SIDEWALL VENTING

Figures 7 and 8 show typical horizontal sidewall venting. For combustible wall passage of vent piping, a UL listed thimble or flashing and sealing boot must be used, providing the wall thickness from 3" minimum up to 12" maximum. The vent piping must terminate with a screened tee or elbow termination facing down.

CAUTION: Flue gasses exiting from the vent terminal will condense. Building materials in the area of the vent terminal should be protected from discoloration and degradation.

An existing chimney (see Figure 10) may be used as a chase for vertical venting. Other appliances CANNOT be vented into the same chimney or vent pipe with in the chimney.

The vertical vent piping must terminate with a screened tee, combination of 45˚ elbow and a 90˚ screened elbow termination or a rain cap termination.

II. DIRECT VENT INSTALLATION

Air intake piping from outside to the boiler air intake connector provides the air for combustion. The boiler surrounding may be contaminated (See page 5). Piping the air intake to the outside can prevent contaminants from the boiler surrounding from entering the combustion air supply.

A. SIDEWALL DIRECT VENTING

Figures 11 and 12 show typical sidewall direct venting, using a Slant/Fin vent/air intake termination. There are 2 different models of vent/air intake termination available. One is designed specifically for PVC/CPVC venting, and the other is designed specifically for stainless steel venting systems. Only these 2 models of vent/air intake termination are approved for this method of installation. Refer to the Slant/Fin Lynx LX-85 Parts List (publication number LX-10PL) for the appropriate model for the vent material to be used.

CAUTION: Flue gasses existing from the vent terminal will condense. Building materials in the area of the terminal should be protected from discoloration and degradation, in addition to the requirements of the vent termination location and clearances stated in this manual.

VENTING AND AIR INTAKE SYSTEM REGULAR INSPECTION

A. Inspect the system regularly for condensation, corrosion,

sagging and/or physical damage. A qualified professional should service the boiler annually and include such an inspection at that time. The homeowner should look over the system monthly for damage, water stains, any signs of rust, other corrosions or separation of the vent and air intake piping (if direct-vent).

B. Should an inspection turn up signs of condensation,

corrosion, sagging or damage, the boiler should be shut down immediately and the condition should be corrected by a qualified professional.

CONDENSATE REMOVAL SYSTEM

The Lynx LX-85 is equipped with a built-in condensation drain and trap. The trap must be filled with water. DO NOT operate the boiler without filling the trap with water to prevent flue gas discharge into space. If the trap is disassembled for inspection, it must be reassembled and filled with water as before.

A 3/4” PVC tee, located on the left rear of the boiler jacket, is provided to run the condensate liquid from the boiler. Connect the plastic tubing that will be run to the drain to the bottom take-off of the tee. Leave the top take-off of the tee open, to act as a vacuum breaker. If the building drain is above the bottom portion of the tee, a condensate removal pump will be required. This pump must have an overflow switch, and be compatible with the acidic condensate liquid, as must all fittings and the tubing used in this condensate removal system. (See Figure 15).

No part of the condensate removal system can be exposed to freezing temperatures, or any other conditions that could cause blockage. DO NOT run drain tubing to the outside of the building. In addition, certain jurisdictions or drain pipe materials may require a neutralization unit to be installed in the condensate removal system. Any piping other than plastic types will be subject to corrosion or deterioration from the acidic condensate, which may have a pH level as low as 3.0. A condensate filter containing lime, marble, or phosphate chips can neutralize the condensate to a pH level above 6.5, which is safe for all drain piping materials. (See Figure 15). The neutralizing filter

medium will require periodic changing, to ensure it’s affectiveness. Replacing the medium on an annual basis is recommended, or refer to the manufacturer’s instructions for systems that are available for neutralizing condensate.

COMMONWEALTH OF MASSACHUSETTS SPECIAL REQUIREMENT

When the Lynx-85 is installed and used in the Commonwealth of Massachusetts, a neutralization unit MUST be installed in the condensate removal system.

GAS PIPING

A. Local installation codes apply. The pipe joint compound

used on threads must be resistant to the action of liquefied petroleum gases.

B. The gas supply line to the boiler should run directly from the

meter for natural gas or from the fuel tank for L.P. propane gas. A manual gas supply shut-off valve is provided on the boiler’s gas supply pipe. (See Figure 3, on page 3). Local codes may specify a manual main gas supply shut-off valve to be 5’ above the floor, and a disconnection union at the gas piping entrance to the boiler. In this case, unless the boiler is wall mounted at the right height, the gas supply shut-off valve must be relocated to the specified location. If the gas supply pipe must be upsized for flow considerations, then the same size main gas supply shut-off valve must be used.

Selecting pipe size for natural gas:

1. Measure or estimate the length of piping from the meter to the installation site.

2. Consult gas supplier for heating value of gas (Btu/cu. ft.).

3. Divide boiler rated input by heating value to find gas flow in piping (cu. ft. per hour).

4. Use table below to select proper pipe size.

EXAMPLE: Boiler model LX-85 is to be installed. Distance from gas meter to the boilers is 30 ft. Heating value of natural gas is 1020 Btu/cu. Ft. Select proper pipe size.

Gas flow = 85,000 Btu/hour

1020 Btu/cu. ft.

= 83 cu. ft. per hour

Lynx Model LX-85

At 30 ft. length of pipe, match required capacity from table on this page (choose higher capacity, in this case is 152 cu. ft. per hour). Required pipe size is

⁄4".

Improper gas pipe sizing will result in flame outages, insufficient heat and other installation difficulties. For more information and also if other appliances are to be attached to the piping system, see Appendix C of National Fuel Gas Code ANSI Z223.1-latest edition.

C. The boiler and its gas connection must be leak tested

before replacing the boiler in operation. Use liquid soap solution for all gas leak testing. DO NOT use open flame. This boiler and it’s individual shutoff valve must be disconnected from the gas supply piping system during and pressure testing of that system at test pressures in excess

⁄2 PSIG. This boiler must be isolated from the gas supply piping system by closing its individual manual shutoff valve during any pressure testing of the gas supply piping system at test pressures equal to or less than

⁄2 PSIG.

D. All gas piping used should be inspected thoroughly for

cleanliness before makeup. A sediment trap is integrally provided, as illustrated on page 3.

E. The minimum and maximum gas supply pressure (at the

inlet of gas valve) are shown on the boiler rating plate for the type of gas used. Gas supply pressure should never be less than minimum or more than maximum pressure when the boiler or any other appliance is turned on or off.

At pressure drop of 0.3 in. water, specific gravity = 0.6.

ELECTRICAL WIRING

All field wiring to the boiler is connected to the 2 sets of terminal strips, located in a junction box behind the jacket top panel. (See Figure 3, on page 3)

DANGER: Before wiring always turn off electric power supply. Otherwise, shock or death can result.

Boiler must be electrically grounded in accordance with the requirements of the authority having jurisdiction, or, in the absence of such requirements, with the National Electrical Code, ANSI/NFPA 70-latest edition.

Proper polarity is critical for the power supply connections. Reversed polarity will cause system lockout. Proper grounding is critical for boiler operation, connect the ground wire to the green ground screw next to the line voltage terminal strip.

2. Circulator(s)

A set of terminals are provided for the boiler loop circulator. Only wire this circulator to these terminals, additional circulators for the space heating system loop require the use of relays and a separate power source.

For multiple zoning, either zone valves or circulators may be used.

For zone valve system (See Figure 17a).

For pump zoning system (See Figure 17b, c, d, e).

DO NOT use boiler transformer to power external accessories like zone valve and relays, overload and/or burned out transformer and boiler malfunction can result. Use separate transformer to power such components.

A second set of terminals are provided for the domestic hot water tank circulator (if used). The boiler loop circulator is always de-energized when the DHW tank circulator is energized, or vice-versa, depending on the priority feature selected.

3. SPACE HEATING THERMOSTAT(S)

Install thermostat on an inside wall and away from any heat sources, sunshine and drafts. A set of terminals are provided for connection of 24 volt style thermostats, relays or zone valve end switches (isolated contacts). (See wiring diagrams Figure 16a,17a, 17 b, 17c, 17d, 17e).

Thermostat heat anticipator: For a non-zoned system set thermostat heat anticipator to 0.1 Amps, for zoned system set to match power requirements of zone valves or relays. Refer to manufacturer’s instructions and specifications. Also see instructions with thermostat.

4. DOMESTIC HOT WATER TANK THERMOSTAT

A set of terminals are provided for connection of the DHW tank thermostat (if used). (See wiring diagram Figure 16a).

5. OUTDOOR AIR SENSOR

A set of terminals are provided for connection of an outdoor air sensor (if this method is used). (See wiring diagram Figure 16a).

1. Power Supply

A separately fused circuit is recommended. Use standard 15 Amp. fuse or breaker and 14 gage conductors in BX cable or conduit.

Provide disconnect means and overload protection as required. See boiler wiring diagram (Figure 16a) boiler control (Figure16b) and ladder diagram (Figure 16c).

The outdoor air sensor that is supplied with the boiler is a 12k ohm type. Mount on an outside wall, shielded from direct sunlight or flow of heat or cooling from other sources. See instructions provided with sensor.

6. LOW WATER CUTOFF

A set of terminals are provided for connection of a LWCO. If this device is used, remove the factory installed jumper from these terminals. (See wiring diagram Figure 16a).

WATER PIPING

1. Connection of system to boiler:

Primary/secondary piping of the system is recommended, to ensure the proper flow through the boiler. (See Figures 20 through 22). The boiler loop piping must be the same diameter as the water outlet (supply) and inlet (return) piping connections provided on the boiler, particularly on longer loops. See page 2 for piping connection size.

2. Circulator Pumps:

The boiler loop piping must utilize the Taco 0011 circulator that is supplied with the boiler, to ensure the proper flow through the boiler. Refer to Figure 19 for the boiler water side pressure drop and Table 2 for the recommended pump models for the domestic hot water system. Install the pumps in the orientation shown in Figures 20 through 22.

3. Relief Valve(supplied with boiler):

Tee the relief valve into the boiler water outlet (supply) piping as close to the water outlet (supply) connection as possible. (See Figure 18). The relief valve’s discharge piping must be the same size or larger than the relief valve’s outlet, and must terminate 6” minimum from floor with a plain (no threads) end. Place a bucket under pressure relief valve discharge. Make sure discharge is always visible. DO NOT hard-pipe to drain piping, or any place where freezing could occur. No shut-off valve is permitted between the relief valve and boiler, or in the discharge line.

4. Air Control System:

An appropriately sized diaphragm-type expansion tank must be used to control the system pressure. See boiler volume data on page 2, and the recommended location in Figures 20 through 22. An air vent is recommended to be installed on an air separator in close proximity to the expansion tank.

5. Cold Water Fill:

A pressure reducing (fill) valve, with a shut-off valve upstream of it, should be installed in close proximity of the expansion tank. (See Figures 20 through 22). Use a back flow check valve in the cold water supply as required by local codes.

6. Low Water Cutoff:

On a hot water boiler installed above radiation level, the boiler must be provided with a low water cutoff device at the time of installation by the installer (see Figure 18 for piping arrangement).

7. Water Treatment and Freeze Protection:

A good water treatment program will not only extend the useful life of this boiler but it will also save much of the time and expense of repairs made necessary by preventable occurrences. A reputable water treatment company should be consulted to evaluate and determine the best overall treatment program for your boiler equipment.

The heat exchanger is made of aluminum, so the system water must be maintained between 7.0 and 8.5 PH level. Thoroughly flush the system, before connecting the boiler, to remove any sediment or glycol.

Anti-freeze is sometimes used in hydronic systems to protect against freeze-up in the event of power failure or boiler shut down in the cold winter. Use RhoGard

(Propylene glycol with Pro-Tek 922 inhibitor) by Rhomar Water Management, Inc. Follow the manufacturer’s

instructions for proper application and proper mixture for minimum ambient temperature. Any use of anti-freeze

other than that supplied b y Slant-Fin or specifically approved and/or recommended for use by Slant-Fin will void the warranty.

Never use any types of automotive or standard gylcol freeze protection fluids. Never use Ethylene Glycol as it is toxic to humans.

8. Piping a heating - cooling system to a water boiler and chiller:

Figure 22 illustrates a method of piping a heating-cooling system to a water boiler and a chiller. Hand valves (shown) or automatic valves must be installed to prevent circulation of chilled water in the boiler or hot water in the chiller.

The air control system and pressure control system must operate with chiller only, or the boiler only, being valved to the piping system. Separate control devices on the boiler and chiller may be used, or a single set of air and pressure controls on the common piping may be preferred.

If the boiler is used to supply hot water to heating coils in air handling units, flow control valves or other devices must be installed to prevent gravity circulation of water in the coils during the cooling cycle.

IV. CHECK COMBUSTION AND FUEL INPUT RATE

A. Remove the boiler jacket top panel, by removing the 2

screws near the back and lifting as the top panel is slid toward the back. Remove the boiler jacket front panel, by pulling forward from the top, and lifting off the pivots at the bottom. (See Figure 26a).

B. Lift the control panel up over the jacketing, by removing the

2 screws in front, and folding at the hinge while lifting upward from the bottom. Position the notches in the side brackets onto the jacket side panel pivots, to secure in place. (See Figure 26b).

C. Remove the heat exchanger enclosure front cover, by

unlatching the 2 top corners and lifting as the cover is pulled forward from the top. (See Figure 26c).

D. Start and run the burner at the maximum firing rate, by

using the “System Test” mode in the “Viewing and changing system setting” menu. Refer to Table 5 on page 32.

1. Measure the CO, and CO2of the flue gas. A flue sample port is provided in the vent pipe (See Figure 3 on page 3). The length of certain combustion analyzer probes may require that the control panel be lowered, in order to insert the probe into the flue sample port. The CO should not exceed 100 ppm, when the combustion is correct. The CO2 should be in the range listed in Table 6.

4. If the fuel input is not at the rate specified on page 2 at the maximum firing rate, then the blower speed should be adjusted to attain the specified input rate. This can be done by using the “Change blower RPM for high input” mode in the “Viewing and Changing System Setting” menu. Refer to Table 5 on page 32. Increasing the blower rpm will increase the fuel input rate, and decreasing the blower rpm will decrease the fuel input rate.

E. In the “System Test” mode in the “Viewing and Changing

System Setting” menu, use the “down” push button to switch to the minimum firing rate. Refer to Table 5 on page 32.

1. Measure the CO and CO2of the flue gas. The CO should not exceed 30 ppm, when the combustion is correct. The CO2should be in the range listed in Table 6.

If the CO2 is not within the range specified for that gas type at the minimum firing rate, then adjust the gas valve offset to the nominal valve shown in Table 6. (See Figure 26d) for the location of the offset adjustment. Remove the cap that covers the offset screw

Turn the offset clockwise to increase the CO2value. Turn the offset counter-clockwise to decrease the CO2value. Replace the offset cap when adjustment is complete.

2. If the CO2is not within the range specified for that gas type at the maximum firing rate, then adjust the venturi throttle to the nominal value shown in Table 6. Turn the throttle clockwise to decrease the CO value. Turn the throttle counter-clockwise to increase the CO2value. See Figure 26d.

3. Once the correct combustion is confirmed at the maximum firing rate, check the fuel input rate on the gas meter.

BTUH INPUT = cu. ft. metered in 3 minutes x

3. Once the correct combustion is confirmed at the minimum firing rate, check the fuel input rate of the gas meter. BTUH Input = cu. ft. metered in 3 minutes x heating valve of the gas * x 20.

4. If the fuel input is not at the rate specified on page 2 at the minimum firing rate, then the blower speed should be adjusted to attain the specified input rate. This can be done by using the “Change blower RPM for low input” mode in the “Viewing and Changing System Setting” menu. Refer to Table 5 on page 32. Increasing the blower rpm will increase the fuel input rate, and decreasing the blower rpm will decrease the fuel input rate.

F. Exit the “System Test” mode, once the combustion and fuel

input rate has been checked and adjusted, if necessary. Refer to Table 5 on page 32.

G. Replace the heat exchanger enclosure front cover, and

secure the 2 latches. Lower the control panel back in place, and secure with the 2 screws. Replace the jacket top panel, and secure with the 2 screws. Replace the jacket front panel, engaging the top area clips to secure..

CARE AND MAINTENANCE

This section must be brought to the attention of the owner by the installer so that the owner can make the necessary arrangements with a qualified service agency for the periodic care and maintenance of the boiler. The installer must also inform the owner that the lack of proper care and maintenance of this boiler and any fuel burning equipment may result in a hazardous condition. Installer should discuss contents of the User’s Information Manual (Publication LX-UIM) with the owner.

A trained and qualified service technician should perform the inspection listed in these instructions before each heating season and at regular intervals.

I. GENERAL MAINTENANCE

A. Safety check, see page 38.

B. Vent and air intake system inspection

1. Check for obstruction, condensation, corrosion and physical damage.

2. Check outside termination. Screen and louvers should be free of any debris and must be cleaned as required.

3. Perform “Venting and Air intake System Regular Inspection”, see page 16.

C. Piping

Check the following:

1. Water piping and accessories for leaks. Slightest leaks should be corrected.

2. System to be full of water and pressure to remain stable at correct setting on gauge.

II. ANNUAL MAINTENANCE

IMPORTANT: The spark ignitor must be replaced at the

beginning of each heating season.

III. INSPECTION DURING HEATING SEASON

A. Check water pressure regularly and add water slowly to

system when needed. If much water is added, venting may be necessary. Regular loss of water from boiler system may indicate either a system leak, or a faulty air control system, or a faulty automatic fill valve.

B. Check venting system. See “Venting and Air Intake System

Regular Inspection” on page 16.

C. Check condensation drain trap to be full of water. Check for

deterioration of the tubing. Check that the trap is not plugged.

D. The combustion blower does not require or have provisions

for lubrication.

E. If required, lubricate the circulator as per the manufacturer’s

instruction.

IV. CLEANING

A. Heat Exchanger: In the unlikely event of flue passage or

water passage blockage, service to remedy situation must be performed only by an authorized Slant/FIn representative.

B. Burner: In the unlikely event of blockage or deterioration,

service to remedy situation must be performed only by an authorized Slant/Fin representative.

IF REPLACEMENT PARTS ARE NEEDED

3. Air-control system. Noise and air binding in radiation should not occur.

4. Low water cutoff for operation (see instruction furnished with unit).

D. Boiler Room Air Supply

Check air vents for continuous positive supply of air as required. Air needs are greatest in cold weather if boiler installation is non-direct vent method. Air vents must open and free of obstruction.

WARNING: The flow of combustion and ventilating air to the

boiler should not be obstructed.

When parts are needed, refer to boiler model and serial number shown on the boiler name/rating plate. Refer to publication number LX-10PL replacement parts for part numbers. Whenever possible refer to the original order by number and date.

Control identification and replacement should not be attempted by unskilled personnel. Only, simple easily - identified controls and parts may be obtained locally. All other control and parts should be identified by and ordered from Slant/Fin. Relief/Safety valves must be ASME rater for the pressure and gross output of the boiler.

For replacement parts, heating contractors should contact their Slant/Fin boiler distributor.

A conversion kit, complete with the appropriate orifice disk and conversion label, is available for performing this procedure. Refer to the Lynx model LX-85’s boiler’s parts list publication LX-10PL for the kit part number. This conversion kit can only be used for the LX-85 boiler. The following procedure for performing the conversion to Propane is intended for a Lynx boiler that is not yet installed. If the boiler is already installed, be sure to turn the gas and power supply off, before proceeding. Once the boiler is installed, the combustion should be checked, as per the instructions and specifications on page 36. The fuel input rate for Propane will be approximately as specified on page 2, when the supply pressure is in the range of 10” to 14” w.c.

1. Remove the boiler jacket top panel, by removing the 2 screws near the back and lifting as the top panel is slid toward the back. Remove the boiler jacket front panel, by pulling forward from the top, and lifting off the pivots at the bottom. (See Figure 26a).

2. Lift the control panel up over the jacketing by removing the 2 screws in front, and folding at the hinge while lifting upward from the bottom. Position the notches in the side brackets onto the jacket side panel pivots, to secure in place. (See Figure 26b).

3. Remove the heat exchanger enclosure front cover, by unlatching the 2 top corners and lifting as the cover is pulled forward from the top. (See Figure 26c).

4. Remove the gas valve cable, by turning the single screws on the plug end counter-clockwise until free. (See Figure 27).

5. Disconnect the gas valve supply pipe, by turning the nut at the valve inlet counter-clockwise until free. (See Figure 27).

6. Remove the 2 Torx or Phillips screws securing the venturi to the blower.

7. Remove the venturi/gas valve assembly, taking note of

the position of the gasket behind the venturi, for reassembly purposes.

8. Remove the 3 Torx or Phillips screws securing the gas valve to the venturi. (See Figure 27).

9. Remove the black rubber grommet from the gas valve, by where the venturi was attached.

10. Place the Propane orifice disk into the black rubber grommet, confirm the stamp on the orifice disk matches the number specified on page 2 of this manual for the boiler model being converted.

11. Replace the black rubber grommet, with the Propane orifice disk, into the gas valve pocket from which it was removed.

12. Reassemble the venturi to the gas valve, being careful that the grommet and orifice disk are kept in the proper positions until the screws are secured.

13. Reinstall and tighten the 2 Torx or Phillips screws that secure the venturi/gas valve assembly to the blower.

14. Re-connect the gas valve supply pipe, by aligning properly with the rubber gasket in place, and turning the nut at the valve inlet clockwise until tight.

15. Replace the gas valve cable and secure with the single screws.

16. Affix the Propane conversion label next to the boiler rating plate.

17. If the boiler is in the process of being installed, it is best to check the combustion and make any necessary adjustments before replacing the heat exchanger cover and jacket panels. See page 36 of this manual. If the boiler installation is to occur at a future time, the heat exchanger cover and jacket panels can now be reinstalled, and the combustion check should be performed after the boiler is installed.
