INST ALLA TION, OPERA TION AND SER VICE MANUAL Model SR Pool and Spa Heater Natural Gas/LP Gas TO INST ALLER: Affix these instructions adjacent to the heater .
SAFETY INSTRUCTIONS ( Continued ) Do not attempt to adjust the gas flow by adjusting the reg- ulator setting. Risk of fire or explosion from incorrect fuel use or faulty fuel conversion. Do not try to run a heater set up for natural gas on LP gas (Propane) or vice versa.
DESCRIPTION OF THE HEA TER FIGURE 2 Figure 2 is a diagram of the heater showing how it operates. Precisely matched orifice plates meter the air and gas into the mixer . The blower draws the air and gas through the mixer and forces it into the burner’ s flameholder .
WHA T TO DO IF YOU SMELL GAS • Do not try to light any appliance. •D o not touch any electrical switch; do not use any phone in your building. • Immediately call your gas supplier from a neighbor ’ s phone. Follow the gas supplier ’ s instructions.
6. T urn the knob on the gas control clockwise ( ) to the black line, depress slightly , and turn to “OFF” position. See Figure 4. FIGURE 4: T urning gas control OFF 7. W ait five (5) minutes to clear out any gas. If you then smell gas, ST OP! Follow “B” in the “Before Startup” instructions (Page 4).
The five operating switches are: POOL ON Press this button to govern heater operation by the pool temperature setting. SP A ON Press this button to govern heater operation by the spa temperature setting. OFF Press this button to switch off the heater .
CARE AND MAINTENANCE MAINTENANCE INSTRUCTIONS Risk of fire or explosion from flammable vapors. Do not store gasoline, cleaning fluids, varnishes, paints, or other volatile flammable liquids near heater or in the same room with heater . The following maintenance is recommended every six months and at the start of every swimming season: 1.
INST ALLA TION INSTRUCTIONS Risk of fire, explosion, or asphyxiation if heater is improperly installed, adjusted, serviced or maintained. These instructions are for licensed, certified, trained and experienced installers only . Be sure your installer or service technician holds all required licenses or certification for your area.
CONTROL P ANEL INDEXING The exhaust discharges vertically from outside the vent cover . The heater control panel assembly on top of the jacket can be turned to any of six positions for convenient access to the panel as follows: 1. Unbolt and separate the jacket halves.
The heater is design certified by CSA International for installation on combustible flooring. For installation on car- peting, the heater must be mounted on a metal or wood panel that extends at least three (3) inches beyond the base of the heater . If the heater is installed in a closet or alcove, the entire floor shall be covered by the panel.
VERTICAL VENTING - NEGA TIVE PRESSURE (See Figures 1 1 and 12) V ent the heater vertically in a negative pressure (positive draft) system in accordance with the National Fuel Gas Code, ANSI Z223.
6. See T able 4 for height of vent termination above the roof. 7. Do not run the heater vent into a common vent with any other appliance. 8. Fire Hazard.
4. Install vent pipe so that it can expand and contract freely as the temperature changes. Support the vent pipe according to applicable codes and vent manufac- turer ’ s instructions.
• at least 4 feet below or horizontally from, or 1 foot above, any doors or windows or gravity air inlet to a building • At least 3 feet above any forced air inlet located within 10 feet • At le.
A manual bypass valve should be installed across the heater when the pump flow exceeds 120 GPM. See instructions below for setting of the manual bypass. Make sure that the outlet plumbing from the heater con- tains no shut-off valves or other flow restrictions that could prevent flow through the heater (except as noted below).
17 WA TER FLOW RA TE Maximum and minimum water flow rates required by the heater are listed below: T able 8: Maximum and Minimum Flow Rate in GPM If the water flow rate to the heater is above 120 GPM, it must be reduced by installing a manual bypass valve (Figure 17).
18 WA TER PRESSURE SWITCH Hazardous pressure. Do not bypass the W ater Pressure Switch or render it inoperable. Switch Settings The water pressure switch turns off the burner if the water flow is interrupted.
19 To avoid water damage or scalding from operation of the relief valve, install a drain pipe in the outlet of the pressure relief valve that will direct water discharging from the valve to a safe place for disposal. Do not install any reduc- ing couplings or valves in the drain pipe.
20 GAS CONNECTIONS The heater requires a gas supply of not less than 4” wc and not more than 14” wc. Gas supply pressures outside of this range may result in improper burner operation. A minimum inlet pressure of 4” wc is required to maintain input rating.
Connect the hot lead of the power supply to the black wire, the neutral lead to the white wire, and the ground wire to the green wire (See Figure 23). A time clock controlling the filter pump should have a low- voltage Fireman’ s Switch that switches off the heater at least 15 minutes before shutting off the pump.
6. Reinstall and bolt up the jacket halves. The fuse for the Fireman’ s Switch is 1.25 amp 1-1/4x1/4” fast blow fuse, available locally . MAXIMUM TEMPERA TURE SET POINT 1. Unbolt and remove upper jacket halves (see Figure 3, Page 5). 2. Depress clips and remove control board assembly dome (see Figure 9, Page 10).
23 Start here for directions to specific T roubleshooting Chart Hazardous voltage. Can shock, burn or kill. Disconnect power before servicing any components.
24 Heater Will Not Fire - A Start GO TO “HEA TER WILL NOT FIRE - B” Page 25 Heater should fire on demand for heat. Check Fireman’s Switch circuit connections (time clock, wiring, external controller relay).
25 Heater Will Not Fire - B Start Increase POOL/SP A tempera- ture setting on Membrane Pad above actual water tem- perature. Heater should fire on demand for heat. If not, and no other red LED’s light, replace Control Board. Service pump/filter and elimi- nate other flow obstructions.
26 Heater Will Not Fire - C Start Go to “INITIAL TROUBLESHOOTING” Continue to observe heater for several minutes. Cycle heater on and off several times. Observe for delayed or rough ignition, poor combus- tion, premature extinction of flame, evidence of boiling, or operation of any diagnostic LED.
27 Heater Will Not Fire - D Start Gas flows during igni- tion try , but burner does not fire. Check for 120 V AC at Igniter leads during ignition try . Check for 120 V AC between S1 and S2 terminals on Ignition Control Module during ignition try . Check for 120 V AC between L1 and L2 terminals on Ignition Control Module.
28 Diagnostic LED’ s: AGS, AFS, HLS, PS, THERMIST OR Do not jumper a safety switch to remedy a failed switch. NOTE: ES1 is a spare and should be jumpered. Service pump and filter to restore proper flow . After ser- vicing, verify proper operation of Pressure Switch (PS).
29 Diagnostic LED’ s: SFS Replace Heater Membrane Pad Assembly , reset power to Heater and retry . Heater should fire. Replace Heater Membrane Pad Assembly , reset power to Heater and retry . Heater should fire. Replace Heater Control Board with new style board, reset power to Heater and retry .
30 Burner T roubleshooting SYMPTOM CAUSE REMEDY Loud, high-pitched whine Flame is too rich. V erify pressure tap between gas valve and blower inlet. T urn to Page 19 and verify that the gas regulator setting is 0.2”wc below the blower inlet pressure.
