CGTH USE AND CARE MANUAL

2.Turn off all electric power to the heater if service is to be performed.

3.Turn off the manual gas valve in the heater

supply line.

7.Reset is accomplished by removing power from the heater for at least five seconds.

8.With a three-try module, when the flame is established and then lost on the first or second trial, the gas valve will automatically turn off. A purge and trial for ignition will then occur.

5.6Sequence of Operation

1.When the thermostat calls for heat, the blower motor will energize.

2.When the motor approaches nominal running speed, the pressure switch closes and activates the ignition module which in turn initiates the purge.

3.The ignition module then energizes the spark igniter.

4.When sparking begins, the gas valve is ener- gized.

5.If a flame is detected, the gas valve remains open. When the call for heat is satisfied, the sys- tem control mechanism de-energizes and the gas valve is turned off.

6.If no flame is detected, the gas valve is closed, and a purge period begins. After the purge period, the ignition module energizes the spark igniter and the gas valve. If a flame is still not established, a third and final purge/ignition sequence is begun. After three failed attempts, the system control mechanism will lock out for a period of one hour or until the unit is reset.

5.7 Venting

As mentioned on Page 5, Section 3.7, it is the Installer’s Responsibility to properly vent (exhaust) the heater outside. Please make sure your heater is vented. If it is not vented, do not use the heater. Immediately call your installer.

Your heater may be vented in one of three ways: horizontal through the wall, horizontal with an elbow through the wall or vertical through the roof. You should know the way your heater is vented. Refer to the following drawings to determine the type of vent- ing you have. If you are not sure, please contact your installer.

WARNING

Carbon Monoxide Hazard

Heater must be exhausted outside. Use materials supplied.

This heater needs fresh air for safe operation and must be installed so there are provisions for adequate combustion and ventilation air.

Failure to follow these instructions can result in death or injury.
