WARNINGS - Pay Attention to These Terms DANGER: Indicates the presence of immediate hazards which will cause severe personal injury, death or substantial property damage if ignored. WARNING: Indicates the presence of hazards or unsafe practices which could cause severe personal injury, death or substantial property damage if ignored. CAUTION: Indicates the presence of hazards or unsafe practices which could cause minor personal injury or product or property damage if ignored.
WATER CHEMISTRY • NOTE: Corrosive water voids all warranties. • Chemical imbalance can cause severe damage to your heater and associated equipment. Maintain your water chemistry according to Table A. If the mineral content and dissolved solids in the water become too high, scale forms inside the heat exchanger tubes, reducing heater efficiency and damaging the heater. If the pH drops below 7.2, this will cause corrosion of the heat exchanger and severely damage the heater.

INSTALLATION Clearances less than these may require removal of the heater to service either the heat exchanger or the burner tray. In either case, the heater must be installed in a manner that will enable the heater to be serviced without removing any structure around the heater. Installation Codes Installations must be in accordance with local, state, provincial, and national codes, laws, regulations and ordinances.
Fig. 4: 130A Dimensions Heater with Outdoor Stackless Top In areas of daily high winds, it may be necessary to replace the outdoor stackless top with a stack adapter in combination with a wind-resistant/weather-proof outdoor stack. See Fig. 5. Heaters must not be installed under an overhang of less than 3 ft from the top of the heater. Three sides must be open in the area under the overhang. Roof water drainage must be diverted away from heaters installed under overhangs with the use of gutters.
Indoor Installation All Air From Inside the Building The heater is design-certified for indoor installation when equipped with the approved drafthood. Each opening shall have a minimum net free area of 130 sq. in. All Air From Outdoors NOTE: For Canada, indoor installation is restricted to an enclosure that is not occupied and does not directly communicate with an occupied area. Refer to the latest edition of CAN/CGA-B149 for specific requirements.
4 ft Minimum 4 ft Minimum 4 ft Minimum 3 ft Minimum 1 ft 10 ft Minimum Minimum Forced Air Inlet Fig. 7: Outdoor Installation Clearances and inspection. Vent pipe should be adequately supported to maintain proper clearances from combustible construction. Type "B" double-wall or equivalent vent pipe is recommended. However single-wall metal vent pipe may be used as specified in the latest edition of the National Flue Gas Code ANSI Z223.1 (Canada - CAN/CGAB149).
Gas Pressure Adjustment Locations Gas Pressure Adjustment (field supplied) A. (field supplied) Fig. 10A: Honeywell DSI VR 8205 Gas Valve (field supplied) Gas Pressure Adjustment Fig. 9: Gas Line Sediment Trap NOTE: Do not use Teflon tape on gas line pipe thread. A flexible pipe sealant suitable for LP gases is recommended. Gas Pressure Regulator If adjustment is needed, remove seal and turn adjustment screw clockwise to increase pressure or counter-clockwise to decrease pressure. B. Fig.
Electronic Ignition Gas Valves Plumbing from the heater back to the pool or spa must not have any valves or restriction that could prevent flow when the pump is operating. Heater must be located so that any water leaks will not damage the structure of adjacent area. PVC pipe may be glued directly into optional or field-supplied header unions. Manual Shut-Off Valve Flow Rates Manometer Model No. Min.
High-temperature CPVC header flanges and header flange nuts are available as an option. If there is any possibility of back-siphoning when the pump stops, it is recommended that a check valve (or valves) also be installed in the system. From Heater To Heater Full Port Ball Valve or Globe Valve Internal Automatic Bypass Valve A built-in automatic bypass valve is provided in the In/Out header. The internal bypass valve automatically responds to changes in water pressure in the piping system.
If required, this needs to be installed in a field-supplied fitting external to the heater. The valve shall be installed in a vertical position. Do not over-tighten. Install pressure relief valve hand tight plus 1/2 turn. When installing a remote switch, do not exceed 10 ft of wiring from the heater. Use 18-gauge stranded wire. WARNING: To avoid water damage or scalding due to relief valve operation, drain pipe must be connected to valve outlet and run to a safe place of discharge.
Control Adjustments—Millivolt Installation Instructions—240 Volt The pool or spa water temperature is controlled by the thermostat on the upper front panel of the heater. The control center contains an On/Off toggle switch and a thermostat. The switch functions as a means for turning the heater On or Off. CAUTION: This appliance has provisions to be connected to an alternate supply source. To reduce the risk of electric shock, disconnect all connections before servicing. 1.

FOR YOUR SAFETY READ BEFORE OPERATING WARNING: If you do not follow these instructions exactly, a fire or explosion may result causing property damage, personal injury or loss of life. A. This appliance is equipped with an ignition device which automatically lights the burners. Do not try to light the burners by hand. B. BEFORE OPERATING, smell all around the appliance area for gas. Be sure to smell near the floor because some gas is heavier than air and will settle on the floor.
FOR YOUR SAFETY READ BEFORE OPERATING WARNING: If you do not follow these instructions exactly, a fire or explosion may result causing property damage, personal injury or loss of life. *If you cannot reach your gas supplier, call the fire department. A. This appliance has a pilot that must be lit by hand. When lighting the pilot, follow these instructions exactly. B. BEFORE LIGHTING, smell all around the appliance area for gas.
Post Start-Up Inspection Feel the inlet and outlet pipes. Outlet pipe should be only slightly warmer than the inlet. It should not be hot. Igniter Minimum Spark Gap is 0.15” - 0.18” WARNING: Should overheating occur or the gas supply fail to shut off, turn off the manual gas control to the appliance. 3/8” Nominally from burner surface With the heater on, remove the door and make a visual check of the pilot and burner. The flame should be blue with a well-defined pattern. Fig.
Winterizing the Pool/Spa Heater Yellow flame means restriction of the air openings. Lifting or blowing flame indicates high gas pressure. Low flame means low gas pressure. Should these occur, shut the heater off and contact your gas supplier or qualified service agency. Heaters installed outdoors in freezing climate areas may be shut down for the winter. Observe the following procedure for winterizing the heater. 5.
2. Turn adjustment knob counter-clockwise 1/4 turn. High Limits 3. Turn pump off and on several times. Heater should shut off immediately. If it does not, repeat the above steps. The heater is equipped with two automatic high limits. Both are located in the In/Out header. Both are set to open at 135°F. NOTE: If heater is installed outside of the limits shown, a higher pressure rated (11 psi) switch may be used.
