5 - Thermostat Closed. Fan & Glo-Bar Operate. Ignition Occurs.
Refer to steps 4.6 - 4.7.
5 - Thermostat Closed. Fan Operates. Switch Light, Valve Light & Glo-Bar
Energized. After 45 Secs., Glo-Bar Shuts Off. No Ignition.
5.1
Be sure that the gas valves inside and outside of the heater are turned to the ON position.
5.2
Locate and confirm that the gas orifice is not plugged with dirt, spider webs or rust.
5.3
Bypass both the Burner & Exhaust Pressure Switches (pg. 19, #6) and then test the voltage coming from the
Circuit Board to the Gas Valve (pg. 8, pic.6) using a volt meter. If there is 120 volts, the gas valve is faulty. If
there is less than 102 volts or no voltage at all, the circuit board is faulty.
5.4
The inlet pressure entering the system may be too high. The maximum value for both natural and propane is
14" W.C.P. Correct this problem by either adjusting the building's regulator down to 14" W.C.P. or by using
step-down regulators in the building's piping system.
NOTE: THE GAS VALVE IS ONLY RATED FOR 1/2 POUND (14 INCHES) OF PRESSURE.
IF USING A HIGH-PRESSURE REGULATOR, BE SURE IT IS LOCKING UP PRIOR TO THE
INLET PRESSURE REACHING 1/2 POUND.
Usually, a heater lacking in efficiency has improper gas pressure, dirty parts or is a misapplication of the heater
itself.
6.1
If the manifold pressure is not high enough, (a minimum of 3.5" natural and 10" propane) the heater will not
deliver the desired amount of heat. Check the Manifold Pressure (pg. 8, pic. 6 and pg. 19, #1 & #2).
6.2
Locate and confirm the orifice is not plugged with dirt, spider webs or rust.
6.3
Check the burner assembly to make sure it is clear of any obstructions.
6.4
Be sure the reflector is in place and clean. Use a soft cloth and aluminum cleaner to clean the reflector.
6.5
Be sure the fan is clean and able to supply the appropriate amount of air to the heater. Clean any obstructions from
the air-intake pipe and cap. Clean the squirrel cage. Oil the motor (SAE-20). Examine and clean the fan blades.
Refer to warnings on cover prior to servicing the unit. Bypass safety pressure switches for supervised troubleshooting purposes only.
*Do not leave switches bypassed while the heater is unattended or for normal operations.
Burner Cycles Off. Burner Recycles.
