If so, backwash or clean WARNING: Check the heater for possible rodent filter. (To tell if your filter is dirty, look to see if the nests after long periods of non-use.
WINTERIZING THE POOL & SPA HEATER COLD WEATHER OPERATION Heaters installed outdoors in freezing climate areas IMPORTANT FREEZE INFORMATION may be shut down for the winter. Observe the follow- ing procedure for winterizing the heater: MODERATE CLIMATE: Heater operation can contin- ue during short-term cold spells.
PART TWO INSTALLATION AND SERVICE INSTRUCTIONS SECTION 1 - RECEIVING EQUIPMENT The manufacturer recommends that this manual be reviewed thoroughly before installing your pool/spa heater. If there are any questions that this manual does not answer, please contact the factory or your local represen- tative.
SECTION 2 - GENERAL SPECIFICATIONS These heaters are design-certified and tested under the latest requirements of the ANSI Z21.56 / CSA 4.7 Standard for Gas-Fired Pool Heaters. All heaters can be used either indoor or outdoors. The appropriate top designated for each type of use is required. If necessary, the top can be changed at a later date to change from outdoor to indoor or vice versa.
CLEARANCES ALL HEATERS For clearances from combustible surfaces, see the When installed according to the listed minimum clear- chart below. ances from combustible construction, the pool heater can still be serviced without removing permanent CLEARANCE FROM construction around the heater. COMBUSTIBLE CONSTRUCTION However for ease of servicing, we recommend a clear- INDOOR INSTALLATIONS:...
Heaters must not be installed under an overhang of less than three 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 the heaters installed under overhangs with the use of gutters.

The power vent assembly is a fan-assisted combustion system designed for application to models 206-407. The unit, when installed as directed, is capable of operating in applications such as through-the-wall venting and reduced horizontal and vertical vent pipe sizes in new and current installations.
For protection against rain or blockage by snow, the GAS SUPPLY CONNECTIONS vent pipe must terminate with a vent cap which com- plies with the local codes or, in the absence of such codes, to the latest edition of the National Fuel Gas Code, ANSI Z223.1 (Canada - CAN/CSA-B149).
GAS PRESSURE REGULATOR ELECTRONIC IGNITION GAS VALVES-CONTINUED The gas pressure regulator is preset at 4.0 in. WC for natural gas (3.1 in. WC for Lo NOx), and 10.5 in. WC. for propane gas. The pressure at the gas valve, taken with a manometer, should be about 4.0 in.
required, use a silicon base such as AquaLube etc. POLYMER HEADERS (STANDARD MODELS) Before attaching the 2-inch unions to the inlet/outlet There are two sets of flange gaskets supplied with header, make sure the O-rings are properly seated in your heater. Use the appropriate gaskets for all your the grooves.

PLUMBING—WATER CONNECTIONS Single Pool Heater Installation Multiple Pool Heater Installation The heater requires water flow and positive 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.
HEAT EXCHANGER REVERSAL PROCEDURE - STANDARD MODELS 1. Remove right and left side access panels (Figure 1). 2. Disconnect wires at high limit, AGS (automatic gas shut-off), and pressure switch on the in/out header (Figure 2). 3. AFT Models: Remove the thermostat temperature sensor by loosening the compression fitting nut (Figure 3).
ELECTRICAL WIRING CAUTION: Heater must be electrically grounded and NOTE: If it is necessary to replace any of the original bonded. Bonding lug is provided loose with the wiring, use 105°C wire or its equivalent, and/or 150°C heater. Install bonding lug on lower right or left side wire or its equivalent, like the original wiring.
TRANSFORMER WIRING 120 VAC WIRING For 120 VAC input power to the unit, connect the black wire to the “L1” or hot leg of the power supply. Connect the white wire to the “Ret” or neutral leg of the power supply. Attach the wire nut to the red wire. There should be no connection to the red wire for 120 VAC operation.
CONTROL PANEL REMOVAL CONTROL ADJUSTMENTS - MILLIVOLT MODELS The water temperature is controlled by the heater ther- 1. Remove screw from front door. Set aside door for mostat on the upper front panel of the heater. The serviceability. control center contains an On/Off switch and one ther- mostat.
THERMOSTAT OPERATION - ADVANCED FLAME TECHNOLOGY (AFT) BOARD Program button LCD Display Temp Buttons Mode Button The pool heater touchpad, located on the upper front the pilot flame current using a bar graph and numeri- panel of the heater, allows the user to select either cal display.
Program Button Fahrenheit or Celsius 1) Remove the four screws holding the control cover, Refer to step one above to access the program and swing the panel down so the back side of the screen. Press the Mode button until Fahrenheit or board is visible (see page 31).
NOTE: The LCD temperature display may not agree with the temperature reading of your pool or spa ther- mometer. The heater reads the water temperature at the inlet. Due to the circulation characteristics of any pool or spa, the water temperature at the inlet to the heater may differ from that observed at a given location in the pool or spa.
REMOTE CONTROL INSTALLATION AND OPERATION CAUTION: Before installing remote controls to the AFT thermostat model heaters, read the following: The digital thermostat model is remote-ready in most cases. The digital liquid crystal display (LCD) shows the actual pool temperature, operating status, and service codes (See examples below). The touch pad on the con- trol panel allows you to select the desired pool or spa temperature.
REMOTE CONTROL WIRING Important Installation Notes for Remote or External Wiring Configuration • Remote wiring must be run in a separate conduit. • Remote wiring must not be run parallel to high voltage lines. • For runs of under 30 feet, remote wiring should have stranded conductors with a minimum of 22 AWG, 600V, cable twisting 1.5 to 2.5 in.
