- Page 12 1 - Thermostat Closed, Fan Does Not Operate If the thermostat is closed (on) and heater does not operate, check the following: Check the building’s main circuit breaker or fuse box. The problem may be a blown fuse or circuit. Thermostat Operation: Verify the thermostat is allowing power to be sent to the heater.
- Page 13 2 - Thermostat Closed, Fan Operates, No Glo-Bar Energization (This step is applicable for all models) Locate any disconnected or loose wires and repair. The normally open Burner Pressure Switch is located on the fan side of the heater (pg. 8, pic. 1 ). This switch must be closed before the glo-bar can be energized.
- Page 14 If steps 2.3.1 - 2.3.4 were performed and the heater still won’t properly function, the exhaust pressure switch is faulty. 2.4 (This step is applicable for DX & XTS models only) Check the Circuit Board (pg. 8, pic. 3). Use a volt meter to ensure that power is actually entering the circuit board.
