• Remove the ash shelf by undoing the screw at each end, pull
shelf towards you.
• Remove one screw from the cover plate located below the
ash shelf. Loosen the other screw (do not remove) swing the
cover plate out of the way and tighten screw down to hold it in
place.
• With along screwdriver rotate spring clips to open or close the
shutter to the desired setting.
The venturies allows the amount of air coming into the fireplace to
be adjusted in order to accommodate different climates and venting
arrangements. Start the pilot and then the burner. Make sure the
pilot flame is burning normally and none of the burner ports are
plugged. Let the fireplace burn for roughly fifteen minutes and
then examine the flames, compare the flames to Figure 37.
The ideal flame will be blue at the base and light orange above. The flames should be of medium height. If the
flames look like this, no venturi adjustment is needed. If the flames are fairly short and mostly blue, the fireplace
is getting too much air. Therefore, the venturies should be closed slightly until the correct flames are achieved.
Flames that are very orange, with tall, dark, stringy tips, are not getting enough air. Open the venturi until the
flames clean up. If the venturi is opened, or closed all the way, and the correct flames cannot be attained, turn off
the gas and contact the dealer.
Warning: Incorrect venturi adjustment may lead to improper combustion, which is a safety hazard. Contact the
dealer if there is any concern about the venturi adjustment.
