CONTROLS

WARNING: Installation, adjustment and service of heater controls including timing of various operating functions must be performed by a qualified installer, service agency or the gas supplier. Failure to do so may result in control damage, heater malfunction, property damage, personal injury, or death.

WARNING: Turn off the power to the heater before installation, adjustment or service of the heater controls. Failure to do so may result in heater malfunction, property damage, personal injury, or death.

CAUTION: This appliance has provisions to be connected to more than one (1) supply source. To reduce the risk of electric shock, disconnect all such connections before servicing.

CAUTION: Risk of electric shock. More than one

(1) disconnect switch may be required to de- energize the equipment before servicing.

Ignition Control Module

The interrupted proved ignition device conserves ener- gy. When additional heat is needed, the combustion air blower starts to purge all air from the combustion chamber for about 15 seconds. On proof of air flow, the air proving switch closes and the igniter is ener- gized, eliminating the fuel costs of maintaining a constant pilot.

To ensure safe operation, the gas valve cannot open until the igniter is verified as capable of igniting the gas. The ignition module is an electronic device which closes the main gas valve within 8/10 of a second whenever the flame is interrupted. The main burner is automatically lit when the device is powered and pre- purged. The unit performs its own safety check.

Modulating Temperature Control (Optional)

This heater can be equipped with a Raypak modulat- ing temperature control. For operation with this control, refer to the Temp-Tracker Installation and Operating Instructions, Raypak Catalog number 5000.66 (P/N 241177).
