Operation and Maintenance, To Start Heater

SECTION 14: OPERATION AND MAINTENANCE

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

14.1 Sequence of Operation

1.Turn the thermostat up. When the thermostat calls for heat, the pump will start immediately. After a short period, the burners will begin their ignition sequence. Sparking will begin at the electrodes and the gas valve will be energized 45 seconds later.

2.The flame will be sensed by the flame sensing rod and the electrode is de-energized.

3.If a flame is detected, the gas valve remains open. When the call for heat is satisfied, the burner shuts off. On CRV-Series systems equipped with the optional ROBERTS GORDON® System Control, or ROBERTS GORDON® ULTRAVACTM, the pump will continue operation for a post-purge period of two minutes.

4.If no flame is detected, the module will close and a purge period begins. If a flame is not established, a second purge and warm-up will take place and then a third trial cycle will begin. After three trials, the module will lockout for one hour or until reset.

5.A reset is accomplished by removing power from the module for at least 5 seconds (thermo- stat cycle is required) or automatically after 1 hour.

14.2 To Shut Off Heater

Set thermostat to lowest setting. Turn OFF electric power to heater.

Turn OFF manual gas valve in the heater supply line.

14.3 To Start Heater

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.

14.4Pre-Season Maintenance and Annual Inspection

WARNING

Explosion Hazard

Service and annual inspection must be done by a contractor qualified in the installation and service of gas-fired heating equipment or your gas supplier.

Turn off gas and electrical supplies before performing service or maintenance.

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

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 52, Section 14.5 for suggested items to inspect.
