Safety Precautions WARNING Asphyxiation Hazard ■ Do not use this heater for heating human living quarters. ■ Lack of proper ventilation air will lead to improper combustion. ■ Do not use in unventilated areas. ■ Improper combustion can lead to carbon monoxide poisoning leading to serious injur y or death. Symptoms of carbon monoxide poisoning can include headaches, dizziness and difficulty in breathing. ■ The flow of combustion and ventilation air must not be obstructed.
WARNING Burn Hazard ■ High surface and discharge temperatures. ■ Do not touch the heater or come within safe clearances given on dataplate. ■ Use extreme caution when lighting the heater or adjusting heat levels. ■ Failure to follow this warning and come too close to the heater can result in burns or ignition of clothing. ■ Burns cause serious injury or death. 1.
Installation and Assembly Instructions GENERAL WARNING Fire and Explosion Hazard Can cause property damage, severe injury or death To avoid dangerous accumulation of fuel gas, turn off gas supply at the heater service valve before starting installation, and perform gas leak test after completion of installation. 1. Read all safety precautions and follow L. B. White recommendations when installing this heater.
12 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. 16. Eventually, like all electrical/mechanical devices, the thermostat can fail. Thermostat failure may result in an underheating condition.
HOSE AND REGULATOR ASSEMBLY Propane Gas 1. Connect rigid end of hose to regulator and tighten securely. FIG. 2 2. Install hose adapter to gas inlet of heater. Tighten adpater securely. Connect end of hose with nut to hose adapter. Tighten hose nut securely. See Fig 3. FIG. 3 Natural Gas -- Connect the components and regulator at the heater’s gas inlet as shown in Fig. 4. Ensure flow arrow on regulator body is in direction of gas flow. Tighten all securely. FIG.
HEIGHT ADJUSTMENT This heater includes a height adjustment feature, allowing the user to change the elevation of the heater for greater heat direction. See Fig. 6 for location of adjustment on front base of heater. FIG. 6 KNOB To adjust the heater’s discharge outlet height: -- Loosen knob -- Lift heater slightly at blower outlet end -- Pull leg to desired setting -- Tighten knob. WARNING Burn Hazard ■ Do not adjust height while heater is operating or hot.
Start-Up Instructions 1. Connect the heater’s electrical cord to an approved electrical outlet. 2. Open the gas supply valve. For LP heaters, this is located on the cylinder or tank. 3. Set thermostat on heater to a setting above room temperature. The heater will start and the burner will ignite. ■ It is normal for air to be trapped in gas hose on new installations. You may need to recycle the heater before air is finally purged from the line and ignition takes place. 4.
Cleaning Instructions WARNING Fire, Burn, and Explosion Hazard ■ This heater contains electrical and mechanical components in the gas management, and safety systems. ■ Such components may become inoperative or fail due to dust, dirt, wear and aging. ■ Periodic cleaning and inspection as well as proper maintenance are essential to avoid serious injury or property damage. 1. Before cleaning, shut off all gas supply valves and disconnect electrical supply. 2.
Service Instructions GENERAL WARNING Burn Hazard ■ Heater surfaces are hot for a period of time after the heater has been shut down. ■ Allow the heater to cool before performing service, 4. Remove the fan guard and motor/fan assembly for access to barrel components. 5. The auto reset limit switches, and thermostat can be tested by disconnecting the leads at the component, and placing a jumper connecting the leads together.: maintenance, or cleaning.
AUTO RESET LIMIT SWITCHES There are two auto reset limit switches on this heater. One is located on the burner plate. The other is located on the underside of the combustion chamber. Either will cut off power to the gas control valve if the heater should overheat. FIG. 11 P Switch mounted on burner plate. See Fig. 10. -- Remove the screws, spacers and nuts holding the switch to the burner plate. N FIG. 10 NUTS,SCREWS, SPACERS HEIGHT ADJUSTMENT LEG TESTING The switches should be tested annually.
IGNITER MAINTENANCE 1. 2. REMOVAL Using a small wire brush, reach down the barrel of the heater and brush the igniter electrode. Remove any build up. 1. Disconnect the ignitIon cable from the igniter. See Fig.16. FIG. 16 Periodically check the gap. Gap should be 3/16 as shown in Fig. 15. FIG. 14 IGNITION CABLE MOUNTING NUT IGNITOR ELECTRODE MOUNTING SCREW 2. Remove the igniter mounting screw and nut. See Figs. 14 and 16. FIG. 15 3/16 in. BURNER ORIFICE 1.
THERMOSTAT 1. Remove knob and thermostat mounting screws. See Fig. 19. 2. Remove the base bottom from the heater. 3. Slide the thermostat sensing bulb from the cable tie at the wiring harness.See Fig. 20. FIG. 20 FIG. 19 BULB THERMOSTAT SCREWS IGNITION CONTROL 1. Disconnect the LED wire harness from the circuit board, if applicable. 2. Disconnect the ignition cable and remove the nuts securing the control to the side of the heater’s base. See Fig. 21. 3.
GAS PRESSURE CHECKS ■ The following explains a typical procedure to be followed in checking gas pressures. ■ The gas pressures will vary depending upon fuel type. ■ Consult the dataplate on the heater or page 4 in this 3. Position the heater upright. Lower the height adjustment leg to elevate the heater and prevent pinching of gauge hose See Fig. 24. FIG. 24 manual for specific pressures to be used in conjunction with this procedure.
