Duct Installation Instructions
Determine the route for the heat duct using the illustration below as a guide.
NOTE:
Air flow through the duct is affected by
length and number of bends. Keep the
length and number of bends to the minimum
to maximize performance.
Blower Box
When the duct penetrates the
fireplace enclosure vertically and the
top of the enclosure is within 36" of
the top of the fireplace, a firestop
spacer that maintains a 1/2"
clearance between all sides of the
duct and any combustible material
must be used.
1/2"
Attach the blower box to the framing or floorboards of the home following the instructions below.
Wall or Ceiling Mounting

framing members for the
blower assembly.
16"*
5-1/4"
* This blower was designed for framing on 16" centers. Construct additional framing if needed.
If the blower is installed prior to the drywall only a 14" opening is required. If installed after the
drywall is in place, the drywall to the sides of the blower will need to be patched.
