4 - Thermostat Closed. Fan & Glo-Bar Operate. Ignition Occurs.
There are two possibilities:
1) The Burner cycles for 8 seconds and shuts off.
4.1
The polarity could be incorrect. Check the systems wiring (pg. 19, #3) (See installation-operation
manual wiring diagram).
4.2
The heater senses flame through ground. Therefore, the unit might not be properly grounded. The
wiring should be inspected (pg. 19, #4).
4.3
There may be loose connections somewhere within the heater, or, the Circuit Board may be faulty.
4.4
The gas pressure is too low. Check the manifold (section 6.1) pressure (pg. 8, pic. 6 & pg. 19, #2) for
appropriate pressure.
4.5
The flame rod might be faulty (pg. 8, pic. 7). Check for visible damage.
NOTE: IF THE PROBLEM IS EITHER THE CIRCUIT BOARD OR THE FLAME
ROD, ONE OR BOTH MIGHT NEED REPLACING.
2) The Burner cycles for more or less than 8 seconds and shuts off.
4.6
Follow steps 4.1 - 4.5.
4.7
The Exhaust Pressure Switch is located on the valve side of the heater (pg. 8, pic. 4). *Bypass this switch
(pg. 19, #6). If the heater works with the exhaust pressure switch bypassed, the problem is with this switch
or what it is sensing and you should continue with step 2.3.1 (located on page 13). If bypassing this switch
does not cause the heater to work, continue with step 2.4 (located on page 13).
4 - Thermostat Closed. Fan Operates. Switch Light &
Disconnected Valve Wire - The wire between the circuit board and the gas valve may be disconnected.
Inspect and reconnect if necessary.
Faulty Circuit Board - If the valve wire is connected properly, the circuit board is faulty and must be
replaced.
NOTE: If the Valve Wire is properly connected and the heater fires, the valve light is faulty.
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 & will not Recycle.
Glo-Bar Energized. No Valve Light.
