To avoid dangerous accumulation of fuel gas, turn off gas supply at the heater’s service valve before starting installation, and perform gas leak test after completion of installation. -- 2. Do not force the safety control button. Use only normal hand pressure to depress the safety control button. Never use any tools.
CARRYING HANDLE ASSEMBLY 1. Fasten the carrying handle to the heater case top using the four (4) sheet metal screws provided. See Fig.1. FIG. 1 HANDLE SCREW 2. The handle may also be fastened to the side of the case top for stacking during storage. Do not stack more than two high. ALTERNATE HANDLE LOCATION HOSE AND REGULATOR ASSEMBLY 1. Always use approved pipe thread compound suitable for use with propane gas on the threaded connections. 2. Assemble the components together as shown in Fig.2.
Start-Up Instructions Refer to Fig.3 and follow steps 1 - 5 on initial start-up. For normal start-up, follow steps 2 and 3. 1. Open all manual fuel supply valves and check for gas leaks using approved leak detectors. 2. Connect the heater’s electrical cord to an approved electrical supply. The fan motor will start and the igniter will spark. 3. Fully depress the button on the safety control valve. The burner will light.
Variable Heat Output 1. This heater has a heat adjustment valve for varying heat output located on the side of the heater. See Fig.4. THIS IS NOT A MANUAL GAS SHUT OFF VALVE. FIG. 4 2. The valve can be adjusted to deliver either minimum heat or maximum heat. When the valve handle is parallel to the gas flow, the valve is completely open to deliver maximum heat output. See Fig. 5. 3.
Cleaning Instructions WARNING Fire, Burn, and Explosion Hazard ■ This heater contains electrical and mechanical components in the gas management, safety and airflow 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 property damage. 1. Before cleaning, shut off all gas supply valves and disconnect electrical supply. 2.
