12.0 adjustments

12.1 restricting vertical vents

Vertical installations may display a very active flame. 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 flame pattern
and creating a more traditional gentle flame appearance. Specific 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 door installed, including 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 flame 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 flame appearance; it is recommended to
adjust the shutter in 1/8" increments.
WARNING
!
• Air shutter adjustment must be done by a qualified installer
Regardless of air shutter location closing the air shutter will cause a more yellow flame, but can lead to
carbonization. Opening the air shutter will cause a more blue flame, but can cause flame lifting from the
burner ports. The flame may not appear yellow immediately, allow 15 to 30 minutes for the flame colour to
be established.
