Operation

!WARNING

Improper operation of the heater may result in explosion, fire, shock and carbon monoxide poisoning. Follow all

guidelines and warnings in this manual and national, state, provincial and local codes. Always conduct safety checks before operating the heater. Do not operate the heater in unsafe conditions.

Important! Before operating the heater, conduct the following safety procedures:

•Check for any possible gas leaks.

•Alert all persons about the hazards of high surface temperature and to keep a safe distance away in order to avoid burns and possible clothing ignition.

•Provide supervision when young children are in the area of the heater.

•Check to make sure clothing isn’t hung from the heater and that flammable materials are not placed on or near the heater.

•Check that all guards or protective devices are in place and secure.

•Check the hose assembly for excessive abrasion, wear or damage. If necessary replace.

•Check control compartment, burners and circulating air passages for debris. If necessary, clean the debris.

Sequence of Operation:

Starting Circuit:

When voltage is applied to L1 and L2, a circuit is completed from L1 via the blower motor to L2. The blower fan is mounted in the control box and rated to supply sufficient air for combustion. Air pressure generated by the blower will cause the normally open pressure switch to close. Another circuit is completed from L1 to the spark ignition module and back to L2. After a seven (7) second pre-purge, the spark electrode and gas valve are energized simultaneously. The trial for ignition is fifteen seconds.

Running Circuit:

After ignition, the flame rod monitors the flame. As long as a flame is present, the valve is held open. If the flame is lost, the control acts to close the valve within one second, and a new trial sequence identical to that at start-up is initiated. If proof of flame is not established within the 15 second trial for ignition, the unit will retry two additional times before entering lockout mode. If lockout occurs, the control can be reset by briefly interrupting the power source.
