ABNORMAL OPERATION

A. NOTHING WORKING

NO VOLTAGE ACROSS:

4 & 1 1. High Limt has tripped and is OPEN. Determine reason for tripping of high limit

2.Bad Transformer

3.Loose or broken connections

4.Blown fuse or circuit breaker

5.Disconnect switch off

6.Harness not plugged into appliance receptacle

B.DAMPER HAS OPENED, NO COMBUSTION VOLTAGE ACROSS:

4 & 1; 4 & 2; 4 & 3: 1. Check for power at ignition module terminals. If 24VAC power is present damper

	2.	is working properly.
		Defective component in appliance after the flue damper.
	3.	If 24 VAC is not present at the ignition module, look for loose or broken
	4.	connections between damper and ignition module.
		If the connections from damper to ignition module seem proper, replace damper
		assembly. If a damper assembly is not available, place the service switch in the
		hold open position. This should keep the damper in the open position and allow
		the customer to have automatic heat, until a replacement damper can be installed.
C. DAMPER ROTATES	Change the entire damper assembly.
CONTINUOUSLY
D. DAMPER STICKS	1. Make sure no screws obstruct the damper blade.
	2.	Make sure damper pipe assembly is not egg shaped.
	3.	Make sure damper rod is not rubbing on pipe assembly.

IMPORTANT: DAMPER MUST BE OPEN BEFORE COMBUSTION TAKES PLACE. If all steps have been tried and damper problems persists call State Technical Center at 1-800-821-2017.
