COMMERCIAL SWIMMING POOL HEATERS
MODEL P – SIZES 514-1223
SUGGESTED SPECIFICATIONS
1. The heater shall be Raypak Model
with BTU input, output. The heater shall be
design certified, ASME inspected and stamped for 160 PSI working pressure, complete with manufacturer’s
data report. The heater shall be equipped with 125 PSI, ASME pressure relief valve. The water tube heat
exchanger shall be of single level horizontal grid design constructed with nine tubes, 1”x.065” wall integral
cupro nickel fin tubes with fins spaced at seven per inch, and extra heavy galvanized steel gull baffles
secured tightly to the tubes above the point of tangency of the fins. Each end of the tubes shall be rolled into
an ASME fire box steel tube sheet and sealed to bronze headers with silicone “O” rings with a temperature
rating over 500°F. The headers shall be precision machined for easy removal and the “O” rings seals shall
positively prevent boiler water from reaching the steel tube sheets. They shall be of high pressure bronze with
integral bronze baffling to direct water through the heat exchanger in two passes.
2. The heat exchanger shall be capable of withstanding a 1000 PSI hydrostatic pressure. The heaters shall be
secured to the tube sheets by properly spaced stud bolts and flange nuts. The heat exchanger shall be readily
cleanable from either the right side or the left side of the heater, and cleanable on the right side without
removing external piping.
3. The heat exchanger shall be explosion proof on the waterside. It shall have 100% copper and bronze
waterways to positively protect the heater from galvanic action (electrolysis).
4. The heater shall be equipped with a 24V main electric gas valve, a factory calibrated pressure switch, a pool
thermostat, and a high limit switch. Electronic Intermittent Pilot Ignition is standard.
5. The heater shall be equipped with stainless or aluminized steel burners mounted in an easily removable
burner drawer. The burners shall be capable of quiet ignition and extinction, and equipped with fixed primary
air ports for atmospheric gas firing and capable of complete combustion.
6. The heater shall be equipped with a Unitherm Governor Bypass Valve to automatically control the internal
water temperature between 105° and 115°F.
7. The heater shall be rated at least 82% thermal efficiency by a recognized independent gas appliance test laboratory,
independent of the manufacturer.
