The heater shall be Raypak Model with BTU input, output. The heater shall bedesign certified, ASME inspected and stamped for 160 PSI working pressure, complete with manufacturer’sdata report. The heater shall be equipped with 125 PSI, ASME pressure relief valve. The water tube heatexchanger shall be of single level horizontal grid design constructed with nine tubes, 1”x.065” wall integralcupro nickel fin tubes with fins spaced at seven per inch, and extra heavy galvanized steel gull bafflessecured tightly to the tubes above the point of tangency of the fins. Each end of the tubes shall be rolled intoan ASME fire box steel tube sheet and sealed to bronze headers with silicone “O” rings with a temperaturerating over 500°F. The headers shall be precision machined for easy removal and the “O” rings seals shallpositively prevent boiler water from reaching the steel tube sheets. They shall be of high pressure bronze withintegral 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 besecured to the tube sheets by properly spaced stud bolts and flange nuts. The heat exchanger shall be readilycleanable from either the right side or the left side of the heater, and cleanable on the right side withoutremoving external piping.3. The heat exchanger shall be explosion proof on the waterside. It shall have 100% copper and bronzewaterways 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 poolthermostat, 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 removableburner drawer. The burners shall be capable of quiet ignition and extinction, and equipped with fixed primaryair 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 internalwater 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.
