Installation 9 InstructionsInstallation HEATER DESCRIPTION Figure t 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 flame holder.A sealed heat exchanger surrounds the Al- flame ,.flame holder,discharging exhaust gases out the flue. /---, Two inch PVC water piping connects directly to the manifold/header on the heat exchanger using 2 PVC slip unions.provided with the CPRS ,c heater.The outer manifold remains cool;no heat sinks are required. A thermal regulator and an internal bypass regulate the water flow g YP g �,, -� �• -� through the heat exchanger to maintain the correct outlet temperature.The heater operator control panel board assembly is located on top of the heater. F SEQUENCE OF OPERATIONx� S"JAiCe�-��" H8J1(ftg CSs.iS {Y An electronic temperature sensing thermistor in the manifold " , adapter inlet controls the heater operation. When the inlet water. temperature drops below the temperature set on the operating Figure 1. control,[lie burner controller supplies power to the combustion air blower through a series of safety interlocks.The interlocks consist of: •the pressure switch(PS),which senses that the pump is running; • the high.limit switch(HLS),which opens if the heat exchanger outlet temperature goes above 1351 I'(S7°C),and • the air flow switch(ATS),which senses the pressure drop acrossthe air metering orifice, •the automatic gas shut-off(AGS)switch,which opens if the heat exchanger outlet temperature goes above 1401 F (601 Q. •the stack flue sensor(SCS),which shuts down the heater if the flue gas temperature reaches 5001 F(2601 C). The air flow switch(AFS)senses the pressure drop across the air metering orifice.As soon as there is sufficient air flow, the AES closes,closing the circuit tothehot surface igniter(HSI),whi6 ignites the fuel mixture.Ott a call for heat,the blower and HSI are energized. In about 20 seconds,the gas valve opens and ignition occurs.The HSI then switches to a sensing mode and monitors the flame. The heater is equipped with a digital operating control that enables the user to pre-set:the desired pool and spa wafter temperatures.The control enables the user to select between pool and spa heating, and.features a digital display that indicates the water temperature, PUTTING THE HEATER INTO SERVICE If the heater is installed below the level of the pool,or more than.two feet above pool level,the pressure switch setting should be adjusted.See WATER PRESSURE SWITCH, in the SAFETY CONTROLS Section. Before putting the heater into service for the first time,follow the instructions under"BEFORE STAR:-UP"(page 32) in the front-of this manual. Check for proper operation of the heater by following the steps under "OPERATION INSTRUCTIONS." Damage to equipment caused by improper installation or repair will void the warranty.

Pool C) S a'`--1 Make sure that the outlet plumbing from the heater contains ` � p 01k r no shut-off.valves or other flow restrictions that could prevent ;cj Pum flow through the heater (except for below pool as noted t below,or winterizing valves where needed).To switch flow between the pool and spa,use a diverter valve.Do not use L 4 any valve that can shut off the flow. Do not use a shut-off From Pooh sway 3-Way valve to isolate the heater unless it is below the level of the Valve Figure S. Valve pool or spa. Install the chemical feeder downstream sof the heater. Install a chemicalresistant one-way check valve between the heater and the chemical feeder to prevent back-siphoning through the heater when the pump is off, NOTICE:If the heater is plumbed in backwards,it will cycle continuously..Make sure piping from filter is not reversed when installing heater. Connect the heater directly to 2" PVC pipe, using the integral unions provided. Heat sinks are not required. The low thermal mass of the heater will prevent overheating of the piping,connected.to the pump even if the heater shuts down unexpectedly. Occasionally a two-speed pump will not develop enough pressure on the low speed to operate the heater.In this case,run the pump at high speed only to operate the lieater.If this does not solve the problem,do not try to run the heater.Instead, correct the installation. Do not operate the heater while an automatic pool.cleaner is also operating.If the circulation.pump suction is plugged(for example by leaves),there may not be adequate flow to the heater.Do not rely on the pressure switch in this case, s BELOW POOL INSTALLATION If the heater is below water level,the pressure switch must.be adjusted.This adjustment must be done by a qualified service technician. See following CAUTION before installation. ACAUTION BELOW OR ABOVE POOL INSTALLATION The water pressure switch is set In the factory at 3.00 PSI(tt 0.75 PSI).This setting is for a heater installed at pool levet. If the heater Is to be installed more than V above or below,the water pressure switch must be adjusted by a qualified service technician. See page 34, Figure 29.. FLOW SWITCH If the heater Is installed more than 5'above the pool or more than 4'below the pool level,you will be beyond the limits of the pressure switch and a flow switch must be installed.Locate and Install the flow switch externally on the outlet. piping from the heater, as close as possible to the heater. Connect the flow switch wires in place of.the water pressure switch wires. P/N 472592 Rev.C 10-5-07 Section 3. Installation 13 GAS CONNECTIONS GAS LINE INSTALLATIONS Before installing the gas line,be sure to check which gas the heater has been-designed to burn.This is important because; different types of gas require different gaff pipe sizes.The rating plate on the Beater will indicate which gas the beater is designed to burn.'file tables,shown on page 14,show.which size pipe is required for the distance from the gas meter to the heater.The table is for natural gas at a specific gravity 'of.65 unci.propane at a specific gravity of 1,55. When Mzinggas lines,calculate three(3)additional Ifeet ofstraight pipe fprevery elbow used.When installing the gas line, avoid getting dirt,grease of,other foreign material in the pipe as this may cause damage to the.gas valve,which inay result in heater failure. The gas meter should be checked to make sure that it will supp y enough gas to the.heater and any outer appliances that may be used on the same meter: The gas line from the meter will usually be of a larger size than the,gas valve supplied with the heater; Therefore a reduction of the connecting gas pipe will he necessary. Make this reduction as close to the heater as possible. The heater requires a gas supply of not less than 4" (10.2cm) Nve and not more than 14" (35.6cm) we. Gas supply pressures outside of this range may result in improper burner operation.A minimum flowing or dynamic inlet pressure (while the heater is running)of 4"(10.2cm)we is required to.maintain input rating with no more than a 2"pressure drop between static and dynamic. The gas supply must be installed in accordance with the National Fuel Gas Coda, ANS1Z223.1, or standard CSS B149.1,Natural Gas and f?rupane Installation Codes,as applicable and all applicable local codes.Install a manual shut-off valve and a sediment trap and union located outside the heater panels,see Figure& Do not use a restrictive gas cock.The following fniiaimum gas pipe sizes are recommended for natural gas supply piping, see Table 2 on page 14.For low pressure LP gas,pipe size may be reduced by 114",with a minimum pipe size of 1f2". Check for compliance with local codes. The heater and any other gas appliances trust:be disconnected from the gas supply piping system during any pressure testing on that system, (greater than %z PSI).The heater and its Was connection must be leak tested before placing the heater in operation. Do not use flame to test the gas line. Use soapy water or another nonflammable method. NOTE A manual main shut-off valve must be installed externally to the heater.

The filter pump should run continuously when the heater is on,and for at least la minutes after the beater turns off.Any switches in the pump circuit(including circuit breakers) that can disconnect the pump must also disconnect the heater. 1 .. 7. Do not wire single-pole switches,including protective devices,into a t :. grounded line.The heater is not sensitive to polarity. Connect the L1 of the power supply to the black wire,the t,2 or neutral r lead to the red wire,and the ground wire to the greets wire.A time clock controlling the filter pump should have a low-voltage Fireman's Switch that switches off the heater at least 15 minutes beforeshutting off the � pump. Always use crimp t)pe connectors when connecting llvo.wires. Ac Plug i 120 Vast or 240 Volt a� Figure 20. P/N 472592 Rev.0 10-5-07 Section 3.
