Failure to follow these instructions can result in death, electric shock, injury or property damage.

The heater is equipped with a dual direct spark ignition system.

12.1 Sequence of Operation

Turn OFF electric power to heater.

Turn OFF manual gas valve in the heater supply line.

12.3 To Start Heater

1.Turn the thermostat up, the blower motor will energize.

2.When the motor approaches nominal running RPM, the pressure switches will close and acti- vate the ignition module.

3.After a 45 second purge period, the ignition module then opens the gas valve and energizes both spark igniters. The light will be illuminated at any time the gas valve is energized.

4.When both flames are established, the sparking sequence ceases.

5.If both flames are not established during the ignition sequence, the ignition module closes the gas valve and purge begins. The module will try two additional times for ignition with purge between trials. If ignition is not established dur- ing either of these trials, the module will lock out.

6.After lock out has occurred, the ignition module must be re-set by turning down the thermostat (disconnecting power) for five seconds, and rais- ing it again to the desired temperature.

7.When the thermostat is satisfied, all power to the heater is shut off.

12.2 To Shut Off Heater

Set thermostat to lowest setting.

Turn gas valve and electric power OFF and wait five minutes for unburned gases to vent from heater. Turn ON main gas valve.

Turn ON electric power.

Set thermostat to desired temperature. Burner should light automatically.

12.4Pre-Season Maintenance and Annual Inspection

To ensure your safety and years of trouble-free operation of the heating system, service and annual inspections must be done by a contractor qualified in the installation and service of gas-fired heating equipment.

Turn off gas and electric supplies before performing service or maintenance. Allow heater to cool before servicing.

Before every heating season, a contractor qualified in the installation and service of gas-fired heating equipment must perform a thorough safety inspection of the heater.

For best performance, the gas, electrical, thermostat connections, tubing, venting, suspensions and overall heater condition should be thoroughly inspected.

NOTE: Gas flow and burner ignition are among the first things that should be inspected. Please see Page 51, Section 12.5 for suggested items to inspect.
