10.4 RESTRICTING VERTICAL VENTS - MODEL GDS60-1
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. Specifi c instructions are included with the kit.
