    CAUTION: Propane gas is heavier than air and will settle on the ground. Since propane can accumulate in confined areas, extra care should be exercised when lighting propane heaters. OPERATING INSTRUCTIONS AND SHUT-OFF PROCEDURES A. This appliance is equipped with an ignition device which automatically lights the pilot.

  • Page 6: After Start-Up

    AFTER START-UP Feel the inlet and outlet pipes. Outlet pipe should be only slightly warmer than the inlet. It should not be hot. WARNING: Should overheating occur or the gas supply fail to shut off, turn off the manual gas control valve to the appliance.

  • Page 7: Section 3 / Maintenance & Care Procedures

    SECTION 3 / MAINTENANCE AND CARE PROCEDURES To be followed one month after start-up and then semi-annually. 1. Inspect top of heater and draft hood for soot, (a sticky black substance around finned tubes and "V" baffles), and open flue gas passageways.

  • Page 8: Cold Weather Operation

    COLD WEATHER OPERATION MODERATE CLIMATE: Heater operation can con- tinue during short term cold spells. When temperatures are below freezing flow, (continuous pump operation) must be maintained. CAUTION: Do not use the heater to maintain water temperatures just above freezing or for freeze protec- tion.

  • Page 9: Part Two - Installation/Service Instructions

    When ordering under warranty conditions, you must also specify date of installation. Raypak recommends that this manual be reviewed thoroughly before installing your Raypak pool/spa heater. If there are any questions that this manual does not answer, please contact the factory or your local Raypak Representative.

  • Page 10: Clearances

    CLEARANCES WARNING: The heater shall not be located in an area where water sprinklers, or other devices, may cause water to spray through the cabinet louvers and into the heater. This could cause heavy internal rusting or damage some electrical components, and this would void the warranty. ALL HEATERS For clearances from combustible surfaces, see the following chart.
  • Page 11 Heaters must not be installed under an overhang of less than three (3) feet from the top of heater. Three (3) sides must be open in the area under the overhang. Roof water drainage must be diverted away from the heaters installed under overhangs with the use of gutters: The point from where the flue products exit the heater must be a minimum of four (4) feet below, four (4) feet horizontally from or one (1) foot above any door, window or gravity inlet to a building.

  • Page 12: Combustion Air

    INDOOR HEATERS The design is also certified for indoor installation when equipped with the approved draft hood. Locate heater as close as practical to a chimney or gas vent. Heater must always be vented to the outside. See Vent Piping Section for venting details.

  • Page 14: Gas Supply Connections

    GAS SUPPLY CONNECTIONS Gas piping must have a sediment trap ahead of the heater gas controls, and a manual shut-off valve lo- cated outside the heater jacket. All gas piping should be tested after installation in accordance with local code Heater Jacket Manual Shut-Off Valve...

  • Page 15: Plumbing For Water Connections

    PLUMBING FOR WATER CONNECTIONS LOCATION The VERSA heater requires water flow and posi- tive pressure to fire and operate properly. It must therefore be installed downstream of the discharge side of the filter pump. A typical installation is plumbed as follows: 1.
  • Page 16 UNITHERM GOVERNOR OPERATION The patented Unitherm Governor is a thermostatic mixing valve specifically designed to maintain constant heater internal temperature between 105°-115°F de- spite continually changing flow rates from the filter and changing pool temperatures. This narrow range is needed to prevent damaging condensation on the burn- ers which will occur if the heater runs for any length of time below 100°F.

  • Page 17: Electrical Wiring

    NOTE: To avoid water damage or scalding due to valve operation, drain pipe must be connected to valve outlet and run to a safe place of discharge. Drain pipe must be the same size as the valve discharge connection throughout its entire length and must pitch downward from the valve.

  • Page 22: High Limits

    PRESSURE SWITCH The pressure switch, or heater actuator, insures that the heater operates only when the filter pump is in operation. It is factory set at 1.75 PSI for deck level installations. When the heater is located below the level of the spa or pool, it may be necessary to reset the pressure switch to compensate for the no-flow static head.

  • Page 23: Pilot Safety (Iid Units)

    PILOT SAFETY (Millivolt System) The heaters equipped with the standing pilot (millivolt system), have pilot generators which act as a safety device to shut off the flow of gas to the main burners and the pilot burner in case the pilot flame is extinguished.
