1. Do not attempt to install, repair, or service this heater or the gas supply line unless you have continuing expert training and knowledge of gas heaters. Qualifications for service and installation of this equipment are as follows: a. To be a qualified gas heater service person, you must have sufficient training and experience to handle all aspects of gas-fired heater installation, service and repair.
Installation Instructions GENERAL 7. WARNING Fire or explosion hazard. Can cause property damage, severe injury or death. 1. To avoid dangerous accumulation of fuel gas, turn off the gas supply at the heater service valve before starting installation, and perform gas leak test after completion of installation. 2. Do not force the gas control pilot button. Use only normal hand pressure to depress the pilot button. Never use any tools.
9. Light according to instructions on heater or within owner's manual. 10. Make sure the heater has the proper gas regulator for the application. A regulator must be connected to the gas supply so that gas pressure at the inlet to the gas valve is regulated within the range specified on the dataplate at all times. Contact your gas supplier, or the L.B. White Co., Inc. if you have any questions. 11. This heater can be configured for use with either propane gas vapor withdrawal or natural gas.
Start-Up Instructions WARNING Burn Hazard ■ Close the manual main burner valve before lighting the pilot. ■ Failure to do so will result in the main burner igniting ATTENTION On new installations it may take a short time for gas to purge out any air in the pilot line before the pilot stays lit. 3. Keep the pilot button depressed for about 30 seconds to allow the thermocouple to warmup so the pilot stays lit after the pilot button is released. 4.
Cleaning Instructions WARNING Fire, Burn, and Explosion Hazard ■ This heater contains mechanical components used in the gas management and safety systems. ■ Such components may become inoperative or fail due to dust, dirt, wear or aging. ■ Periodic cleaning and inspection as well as proper maintenance are essential to avoid serious injury or damage. 1. Before cleaning, shut off all gas supply valves. 2. The heater should have dir t or dust removed periodically: a.
Service Instructions GAS PRESSURE CHECKS ATTENTION 2. Attach the pressure gauge to this point. See Fig.3. ■ This procedure is to be done once a year prior to the 3. Open fuel supply valves to heater. heating season, anytime the heater is moved from one job location to the next, or after servicing the heater. WARNING ■ Do not disassemble the pilot safety control valve. ■ Do not attempt to replace any components of the pilot C. READING PRESSURES 1. Start the heater.
PILOT ASSEMBLY 1. Shut off gas supply to heater. 6. Reassemble by reversing above steps. 2. Let the heater cool down. B. Thermocouple (See Fig. 4) 3. Remove screws that secure barrel assembly to base of heater. 1. Pull back sharply on the thermocouple’s lead or its body. It will then pop out of its mounting hole. 4. Remove barrel assembly from base, exposing burner and pilot assembly. 2.
IGNITER and ELECTRODE Servicing of the igniter and electrode is needed when a spark at the electrode is not seen. This may happen with hard use over a long period of time, or due to dust and dirt accumulation. If you do not see a spark being generated at the electrode check the following areas: A. Igniter 1. Pull the wire from the push button igniter. 2. Place a metal object, (such as a screwdriver tip) about 1/8 in. from igniter. 3. Push the igniter’s button several times.
Troubleshooting PROBLEMS 1. Pilot will not light. CAUSES * Propane gas tank is empty. * Fill tank. REMEDIES * Fuel supply valves closed. * Open fuel supply valves. * Excess flow valve in P.O.L. fitting on regulator is closed. * Close propane cylinder valve. Wait 5 minutes and open cylinder valve slowly. * Pilot button not fully pushed in. * Push in pilot button completely. * Pilot orifice is plugged. * Clean or replace pilot orifice.
