INSTALLATION

Since some municipalities have additional local codes it is always best to consult with your local authorities and the CAN/CGA B149 installation code.

For USA installations follow local codes and/or the current National Fuel Gas Code, ANSI Z223.1.

When using copper or fl ex connectors use only approved fi ttings. Always provide a union so that gas lines can be easily disconnected for servicing. Flare nuts for copper lines and fl ex connectors are usually considered to meet this requirement.

Important:Always check for gas leaks with a soap and water solution or gas leak detector. Do not use open flame for leak testing.

Note: To properly check gas pressure, both inlet and manifold pressures should be checked using the valve pressure ports on the valve.

1)Make sure the unit is turned OFF.

2)Loosen the "IN" and/or "OUT" pressure tap(s), turning counterclockwise with a 1/8" wide fl at screwdriver.

3)Attach manometer to "IN" and/or "OUT" pressure tap(s) using a 5/16" ID hose.

4)Turn the unit ON.

5)The pressure check should be carried out with the unit burning and the setting should be within the limits specifi ed on the safety label.

6)When fi nished reading manometer, turn off the unit, disconnect the hose and tighten the screw(clockwise)witha1/8"flatscrewdriver.

Note: Screw should be snug, but do not over tighten.

ADJUSTMENT

The burner aeration is factory set but may need adjusting due to either the local gas supply or altitude. Open the air shutter for a blue fl ame or close for a more yellow fl ame.

In order to adjust the aeration, the logs, grate and burners will need to be removed to be able to access the shutters.

Minimum Air Shutter Opening:

NG	Front Burner	1/4"
	Rear Burner	1/8"
LP	Front Burner	5/16"
	Rear Burner	1/4"

CAUTION: Carbon will be produced if air shutter

is tightly closed.

Note: Any damage due to carboning resulting from improperly setting the aeration controls is NOT covered under warranty.
