VR8304 INTERMITTENT PILOT COMBINATION GAS CONTROL

Service

WARNING

Fire or explosion hazard. Can cause property damage, severe injury, or death.

Do not disassemble the gas control; it contains no replaceable components. Attempted disassembly or repair may damage the gas control.

CAUTION

Do not apply a jumper across or short the valve coil terminals. Doing so may burn out the heat anticipator in the thermostat or damage the electronic module.

IMPORTANT

Allow 60 seconds after shutdown before re- energizing the step-opening module to ensure lightoff at steppressure.

IF MAIN BURNER WILL NOT COME ON WITH CALL FOR HEAT

1.Ensure the gas control knob is in the ON position.

2.Adjust the thermostat several degrees above room temperature.

3.Using an AC voltmeter, check for 24V at gas control.

•If pilot lights, measure across MV/PV and MV.

•If pilot does not light, measure across MV/PV and PV before safety lockout occurs.

4.If voltage is incorrect or not present, check control circuit for proper operation.

5.If 24V is present, replace the gas control.

INSTRUCTIONS TO THE HOMEOWNER

WARNING

Fire or explosion hazard. Can cause property damage, severe injury, or death.

Follow these warnings exactly:

1.Pilot flame is lit automatically. Do not light the pilot flame manually.

2.Before lighting the pilot burner flame, smell around the appliance for gas. Be sure to smell close to the floor because LP gas is heavier than air.

3.IF YOU SMELL GAS:

•Turn off the gas supply at the appliance service valve on LP gas systems, turn off gas supply at the gas tank.

•Do not light any appliances in the house.

Automation and Control Solutions

•Do not touch electrical switches or use the phone.

•Leave the building and use a neighbor’s phone to call your gas supplier.

•If you cannot reach your gas supplier, call the fire department.

4.Do not force the gas control knob. Use only your hand to push down or turn the gas control knob. Never use tools. If the gas control knob will not operate by hand, the gas control should be replaced by a qualified service technician. Force or attempted repair may result in a fire or explosion.

5.The gas control must be replaced in case of any physical damage, tampering, bent terminals, miss- ing or broken parts, stripped threads, or evidence of exposure to heat.

IMPORTANT

Follow the operating instructions provided by the manufacturer of your heating appliance. The information below will be of assistance in a typi- cal gas control application, but the specific con- trols used and the procedures outlined by the manufacturers of your appliance may differ, requiring special instructions.

STOP! READ THE WARNINGS ABOVE!

The pilot flame is lit automatically. If the appliance does not turn on when the thermostat is set several degrees above the room temperature, follow these instructions.

1.Set the thermostat to its lowest setting to reset the safety control.

2.Disconnect all electric power to the appliance.

3.Remove the gas control access panel.

4.Push in the gas control knob slightly and turn

clockwise to OFF.

5.Wait five minutes to clear out any unburned gas. If you then smell gas, STOP! Follow Step 3 in the Warnings above. If you do not smell gas, continue with the next step.

6.Turn the gas control knob counterclockwise to

PILOT.

7.Turn the gas control knob counterclockwise to ON.

8.Replace the gas control access panel.

9.Reconnect all electric power to the appliance.

10.Set the thermostat to the desired setting.

11.If the appliance does not turn on, set the gas con- trol knob to OFF and contact a qualified service technician for assistance.

Turning off the Appliance

VACATION SHUTDOWN—Set the thermostat to the desired room temperature while you are away.
