ZERO CLEARANCE INSTALLATION - SPECIFICATIONS (Cont.)
Cooling Vents
Located on the top rear corners of the fireplace are two 6" diameter air duct collars that must
be connected to 6" diameter air ducts that terminate outside. The purpose of the these air
ducts is to provide cooling air for the zero clearance fireplace and the air cooled chimney
system. Air is drawn into the ducts and circulated around the zero clearance fireplace. It then
exits through the outer liner of the chimney system, keeping the zero clearance fireplace and
chimney enclosure cool. The duct terminations must be located so they can not be
accidentally blocked in any manner (i.e. snow drifts). The table below details the maximum
horizontal run the duct may travel in relation to its vertical rise (see the illustration below):
When the vertical rise is between:
The maximum horizontal run can be:
6' and 10'
5'
3' and 6'
15'
1' and 3'
20'
0' and 1'
25'
NOTE 1: As an option to drawing air from outside, the cooling air duct terminations can be
installed to draw air from a crawl space, attic, or garage. Check with your local building
inspections department to determine if this is acceptable in your area. In certain areas this
type of installation requires a certain type of duct termination like one with a fire curtain.
NOTE 2: The maximum number of elbows that can be used in the system are two.
WARNING:
FAILURE TO VENT SYSTEM PROPERLY COULD CAUSE AN
EXTREME FIRE HAZARD.
Vertical cooling vent
terminations must terminate a
minimum of 10' away from the
chimney termination.
