SAFETY INSTRUCTIONS (Continued) Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and dangerous operation. Connect heater to 120 Volt, 60 Hz., 1 Phase power only. Verify proper operation after servicing. Do not allow children to play on or around heater or associated equipment. Never allow children to use the pool or spa without adult supervision. Read and follow other safety information contained in this manual prior to operating this pool heater.
SEQUENCE OF OPERATION DESCRIPTION OF THE HEATER Exhaust Gas 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 control, the burner controller supplies power to the combustion air blower through a series of safety interlocks.
3. Pregnant women beware! Soaking in water above 102°F (39°C) can cause fetal damage during the first three months of pregnancy (resulting in the birth of a brain-damaged or deformed child). Pregnant women should follow the 100°F (38°C) maximum rule. 4. Before entering the spa or hot tub, users should check the water temperature with an accurate thermometer; spa or hot tub thermostats may err in regulating water temperature. 5.
11. Turn on all electric power to the appliance. 12. Press either the POOL ON or SPA ON button switches on the operating control. 13. Set the thermostat to desired setting (NOTICE: Set point must be above actual water temperature or burner will not fire). See OPERATING CONTROL below. 14. The blower should come on immediately, and after about 20 seconds, the burner should fire. When operating for the first time, the burner may not fire on the first try because of air in the gas line.
The five operating switches are: After start-up, the outlet water pipe should feel slightly warmer than the inlet pipe. If it feels hot, or if you hear the water in the heater boiling, there may not be enough water flow to the appliance. Make sure that the filter is not plugged. If water temperature remains high but the unit continues to operate, turn off the appliance and call your service technician. POOL ON Press this button to govern heater operation by the pool temperature setting.
CARE AND MAINTENANCE Explosion hazard. Purging the system with compressed air can cause components to explode, with risk of severe injury or death to anyone nearby. Use only a low pressure (below 5 PSI), high volume blower when air purging the heater, pump, filter, or piping. 4. Remove the Water Pressure Switch. Plug the port in the manifold to prevent bugs and dirt from getting into the manifold. 5. Drain the plastic inlet/outlet manifold through the outlet pipe.
HEATER CLEARANCES – OUTDOOR INSTALLATION INSTRUCTIONS If the heater is located under a roof or deck overhang, there must be at least three feet (3’) clear space between the bottom of the overhang and the top of the heater exhaust vent. The heater must be at least six inches (6”) from the nearest wall (clearance for service access will depend on the installation). If the heater is under a roof or deck overhang, the space around the heater must be open on three sides.
CONTROL PANEL INDEXING INSTALLATION IN A GARAGE OR UTILITY ROOM 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. 2. Pull hair pin clips. 3. Depress plastic clips on the control panel assembly.
The minimum net free area in square inches shall be as follows: The heater is design certified by CSA International for installation on combustible flooring. For installation on carpeting, 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. On an indoor installation, the exhaust discharges into a vent pipe.
rior of the 4” end of the metal Flue Collar. Attach the metal Flue Collar to the Vent Body using the RTV supplied with the kit, following the instructions included with kit. Do not use a draft hood with this heater. 3. Attach the vent pipe to the metal Flue Collar with sheet-metal screws. VERTICAL VENTING - NEGATIVE PRESSURE (See Figures 11 and 12) Vent the heater vertically in a negative pressure (positive draft) system in accordance with the National Fuel Gas Code, ANSI Z223.1, and local codes.
6. See Table 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. HORIZONTAL OR VERTICAL VENTING POSITIVE PRESSURE (SPECIAL GAS VENTING) (See Figures 13 and 14) Vent the heater either horizontally or vertically using one of the 4-inch Special Gas Vent Pipes listed on Page 14 (Table 5). Install the vent pipe in accordance with local codes and the provisions of the National Fuel Gas Code, ANSI Z223.
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 manufacturer’s instructions. Pipe support must allow the vent pipe free movement out and back, from side to side, or up and down as necessary, without putting a strain on the heater or vent body. Slope horizontal pipe runs up from the heater at least 1/4” per foot. Install Listed condensate drains at low points where condensate might collect.
• 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 least 4 feet horizontally from electric meters, gas meters, regulators and relief equipment • At least 7 feet above grade adjacent to walkways or similar traffic areas. Allow at least 3 feet vertical clearance over vent termination when terminating under an overhang or deck.
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 contains no shut-off valves or other flow restrictions that could prevent flow through the heater (except as noted below). To switch flow between the pool and spa, use a diverter valve. Do not use any valve that can shut off the flow.
WATER FLOW RATE Maximum and minimum water flow rates required by the heater are listed below: Table 8: Maximum and Minimum Flow Rate in GPM Model 200 333 400 Minimum Flow 20 33 40 Maximum Flow 120 120 120 Cool Water In If the water flow rate to the heater is above 120 GPM, it must be reduced by installing a manual bypass valve (Figure 17). After installing the valve, adjust the valve to bring the flow rate within the acceptable range.
NOTICE: When the heater is mounted more than five feet above or two feet below the deck level, a Pressure Switch is no longer adequate. A Flow Switch must be installed instead. NOTICE: Heater operation with incorrect Pressure Switch setting may cause operation with no water flow. Operation of the heater without sufficient water flow may severely damage it. Verify proper operation of the water pressure switch at the start of every season and every six months thereafter by the following steps: 1.
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 reducing couplings or valves in the drain pipe. The drain pipe must be installed so as to allow complete drainage from the valve and drain line. The relief valve should be tested at least once a year by lifting the valve lever.
GAS CONNECTIONS PRESSURE TESTING 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. The gas supply must be installed in accordance with the National Fuel Gas Code, ANSI Z223.1, and all applicable local codes. Install a manual shut-off valve and a sediment trap and union located outside the heater jacket (Figure 22).
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 lowvoltage Fireman’s Switch that switches off the heater at least 15 minutes before shutting off the pump. NOTICE: When using a timer and Fireman’s Switch, the heater’s power supply should come from the load side of the timer.
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 TEMPERATURE 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). 3. Push the Max. Temp. Set Point button on the back of the control board (see Figure 26).
