Continuation Trouble Shooting Guide

3d. Excessive vent exhaust or defective air/vent switch.

3d. Excessive negative pressure exerted by the exhaust system on the vent will prevent N.O. combustion air/vent switch from closing. Provide means to relieve pressure and close the N.O. switch. If combustion air/vent switch will not close, replace switch.

3e. Ignition module or igniter may be defective.

3e. Disconnect igniter leads from ignition module. Make sure 24V is present across ignition terminals on the igni- tion module during the ignition cycle. If not, replace ignition module. Check resistance reading across igniter leads. If circuit is open, or reading is greater than 30 ohms, replace the igniter. A new igniter will measure between 1 to 6 ohms at room tem- perature.

3f. Gas valve or the ignition module may be defective.

3f. During the ignition cycle, 24V should be present at the MV1 and GND termi- nals for about 5 seconds. If no 24V is measured, replace the ignition mod- ule. If 24V is present, replace the gas valve.

4.Unit energized, pump and blower running.

Ignitor is glowing.

Burners will not stay lighted.

4a.	Improper ground	4a.	Check ground connections inside
			control box.
4b.	Loose wiring.	4b.	Check all connections and wire nuts.
4c.	Remote sensor	4c. Check wire connection to remote sen-
			sor.
4d.	Insufficient gas pressure.	4d.	Check gas pressure at outlet of valve
			under load, pressure should be:
			3.5 in. W.C.for Natural gas
			10.5 in. W. C. for Propane gas.
