This must be carried out by an AUTHORIZED REPRESENTATIVE OF WOLF STEEL LTD. or a QUALIFIED GAS INSTALLER in accordance with local codes or in the absence of local codes with the requirements of the provincial / state authorities having jurisdiction and in accordance with the requirements of the CAN1-B149 Installation Code in Canada and the ANSI Z223.1 National Fuel Gas Code in the United States.

VENTURI ADJUSTMENT

Remove the 2 screws securing the burner. Natural gas models have air shutters set to 0.031" open (1/32"). Propane models have air shutters set to 0.063" open (1/16").

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

Closing the air shutter will cause a more yellow flame, but can lead to

FIGURE 66 carboning. The flame may not appear yellow immediately; allow 15 to 30 minutes for the final flame colour to be established.

Air shutter adjustment must only be done by a qualified gas installer!

For fuel conversion refer to the instructions included with your conversion kit.
