12.1 restricting vertical vents
Vertical installations may display a very active fl ame. If this appearance is not desirable, the vent exit in the
appliance must be restricted using a restrictor vent kit. Refer to the "replacements" section of the owner's
manual for the appropriate kit. This will reduce the velocity of the exhaust gases, slowing down the fl ame pattern
and creating a more traditional gentle fl ame appearance. Specifi c instructions are included with the kit.

12.2 venturi adjustment

This appliance is equipped with an externally adjustable air shutter that is not preset from factory. Any
adjustments made to the shutter must be done with the burner and all media installed into the appliance. It is
important to operate the appliance and verify that the air shutter is opened to the correct amount to prevent
either fl ame lifting or carbonizing. To open or close the shutter, pull the rod away from the appliance or push the
rod towards the appliance respectively.
Small adjustments on the shutter can have a drastic effect on the fl ame appearance; it is recommended to
adjust the shutter in 1/8" increments.
WARNING
!
• Air shutter adjustment must be done by a qualifi ed installer.
Regardless of air shutter location, closing the air shutter will cause a more yellow fl ame, but can lead to
carbonization. Opening the air shutter will cause a more blue fl ame, but can cause fl ame lifting from the burner
ports. The fl ame may not appear yellow immediately, allow 15 to 30 minutes for the fl ame colour to be established.
