Page 20WARNINGWhen the heater is fired for the first time, thecombustion chamber refractory binder materialis driven out by the heat of the flame. Whitesmoke and/or sharp odors may be emitted fromthe vent during this period. Do not inhalecombustion product fumes at any time, andespecially when these fumes are beingemitted. This "burn-in" period will last only afew minutes.7.3 Lighting and Shutdown ProceduresBefore starting your heater, be sure that you arefamiliar with the setting and operation of the heatercontrols. Once the controls are set to your preferences,follow the instructions outlined on the following page.Read and follow all safety instructions first.A more detailed set of instructions of the opera-tion of the LG controller follows in the next section.NOTE: If your heater is configured to operateon LP gas and the LP tank runs out of fuel, turnoff gas at the heater. After the tank is refilled,the heater must be relit following theinstructions found on the inside of the heater. Acopy of these instructions appear on thefollowing page. DO NOT attempt repairs on thegas control or heater. Tampering is dangerousand voids all warranties.WARNINGDo not attempt to operate the heater with thedoor off. Doing so may cause severe bodilyinjury.7.4 Turning the Heater On/Off andSetting the temperature controlThe temperature control (see Figure 18) iscalibrated at the factory and covers a range fromapproximately 70°F to 104°F (21°C to 40°C). Use anaccurate pool thermometer to determine the bestwater temperature for your uses.The Lite2 temperature control panel has a rockerswitch to turn the heater on and off. It also has a rotarydial to set the desired thermostat setting (see Figure18).Once the heater has been lit by following thesafety and lighting procedures in Section 7.3, set thetoggle switch on the control panel to "ON" to start theheater operation. If the heater senses that the pump ison and the thermostat setting is higher than the tem-perature of the pool/spa water, the pilot will ignite themain burners.NOTE: The heater is designed to run onlywhen the filter pump is running. If the heaterdoes not immediately turn off when the pumpturns off, turn the heater off at the control panel.The heater's pressure switch may needadjusting (see Section 7.5)Once the pool/spa water temperature reachesthe thermostat setting, the heater will automaticallystop firing. As the pool/spa water temperature fallsbelow the thermostat setting the heater will once againstart the heating cycle.Rotate the thermostat dial clockwise to increasethe temperature setting and counterclockwise todecrease the setting. It may take several attempts to setthe thermostat dial to the desired temperature. Be sureto use an accurate thermometer to measure watertemperature. Once the desired temperature setting isfound, loosen the screw on the Temp-Lok ring androtate the ring until the stop rests against the knob.Tighten the screw to hold the knob in position. Thiswill prevent accidental moving of the dial and possibleoverheating of the water.Figure 18. Temperature controls.
