4.Using a deep

9/16” socket wrench, remove the main burner orifice. A 7/8” back-up wrench must be used on the manifold, located below the housing to ensure that the aluminum tubing

does not twist or kink. Replace the correct burner orifice using pipe thread compound.

5.Loosen nut and replace with appropriate injector

6.Reinstall the burner ensuring that the Venturi tube fits over the orifice.

NOTE: Check and adjust, if necessary, the primary air to 7/16” for propane and 1/4” for natural gas. Replace the

screws.

7.Turn on the gas supply and check for gas leaks by brushing on a soap and water solution.

Do not use open flame.

8.Replace the log set. Then light the pilot and main burner to ensure that the gas lines have been purged.

9.Replace the glass viewing door and cast front. Turn on

the electrical supply to the stove.

It is important to periodically perform a visual check of the pilot and the burner flames. Compare them to the figures below. If any flames appear abnormal call a qualified service

person.

VENTURI ADJUSTMENT

Remove the 2 screws securing the burner. Natural gas models have air shutters set to 0.188" open (3/16"). Propane models have air shutters set to 0.375" open (3/8").

After making adjustments replace the burner ensuring that the venturi tube fits over the orifice and replace the screws.

Air shutter adjustment must only be done by a

qualified gas installer!

Closing the air shutter will cause a more yellow flame, but can lead to carboning. The flame may not appear yellow immediately; allow 15 to 30 minutes for the final flame colour to be established.
