Vertical installations may display a very active
fl
ame. If this appearance is not desirable, the vent exit must
be restricted using a restrictor vent kit. Refer to “ACCESORIES” in the “REPLACEMENTS” section 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. Speci
fi
c instructions are included with the kit.
