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 and Assembly Instructions GENERAL -- Check all pipe connections, hose connections, fittings and adapters upstream of the gas control with approved gas leak detectors. WARNING Fire and Explosion Hazard Can cause property damage, severe injury or death -- In the event a gas leak is detected, check the components involved for cleanliness and proper application of pipe compound before further tightening.
13. The heater must be installed so as not to interfere with or obstruct normal exits, emergency exits, doors and walkways. 14. Railing, fencing or suitable substitute materials must be used to keep the heating equipment from any people using and visiting the structure. 15. Eventually, like all electrical/mechanical devices, the thermostat can fail. Thermostat failure may result in an underheating condition.
HOSE AND REGULATOR ASSEMBLY 1. Connect rigid end of hose to gas inlet at heater and tighten securely. See Fig.2. FIG. 2 2. Thread hose adapter to regulator outlet. Connect end of hose with swivel nut to hose adapter. Tighten both securely. See Fig 3. FIG. 3 CONNECTING PROPANE REGULATOR TO PROPANE GAS TANK 1. At the inlet of the regulator is a male nut and stem called a POL. Remove the cap from the POL but do not discard it. Insert POL stem into the valve on the tank.
Start-Up Instructions 1. Connect electrical cord to an approved electrical outlet. 2. Set thermostat on heater to desired temperature. 3. Open the fuel supply valves. Check for gas leaks using an approved leak detector. 4. Position the heater’s power supply switch to ON. The heater will start. ■ 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. 5.
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, maintenance, or cleaning. ■ Failure to follow this warning will result in burns causing injury. WARNING Fire and Explosion Hazard ■ Do not disassemble or attempt to repair any heater components or gas train components. ■ All component parts must be replaced if defects are 4.
AIR PROVING SWITCH 1. Remove fan blade from motor if necessary. 2. Remove screw securing switch assembly to bottom barrel of heater. Rotate the switch so its paddle can be pulled down through the hole. See Fig.6. 3. When installing the replacement switch, ensure mounting bracket’s tab is positioned in hole adjacent to mounting screw hole. FIG. 6 SCREW TAB BACKFLASH SWITCH REPLACEMENT Remove the screws holding the switch to the side of the barrel. See Fig. 7. FIG. 7 2.
IGNITER The tip of the igniter is exposed to a harsh environment consisting of high temperatures and combustion products. Periodic servicing is required. 2. Remove the igniter mounting screw and nut. When replacing, ensure ignitor is positioned as shown in Fig.10, and its gap is set to 3/16 inch. See Fig. 11. FIG. 10 MAINTENANCE 1. Using a small wire brush, reach into the outlet of the heater and brush the igniter electrode. Ensure any buildup is removed. 2. Test the igniter.
THERMOSTAT 1. Open the clip holding the thermostat bulb to the fan guard. Remove bulb from fan guard and fan guard from heater. FIG. 14 3. Unlock the bushing at the thermostat bulb’s access hole at the barrel bottom. See Fig. 16. Guide the bulb down through the hole. Handle the replacement thermostat carefully to prevent damage to the capillary and bulb. FIG. 16 BUSHING 2. Remove knob and thermostat mounting screws. See Fig. 15. FIG. 15 SCREWS IGNITION CONTROL 1.
GAS CONTROL VALVE 1. Loosen the compression nut from the half-union fitting at the gas control valve outlet. See Fig. 18. FIG. 18 2. Remove the screws adjacent to the gas inlet of the heater.
