Installation Recommendations for Cold Environments
If you live in the area depicted in black in the illustration to the
right (or in Canada), we recommend the following steps be
taken to minimize cold air infiltration.
Insulated Chimney is Strongly Recommended
Insulated chimney does not require cooling ducts and is
therefore preferred for cold environments. This is the
number one method for improving cold weather performance.
Use "P" Trap & Insulated Duct in the Cooling Duct.
If using air-cooled chimney, we recommend insulating the
intake duct and putting in a "P" trap to help prevent air
circulation when the fireplace is not in use. A typical "P" trap
design is shown in the illustration to the right.
Use Bi-Metallic Damper with Air-Cooled Chimney
If using air-cooled chimney, we recommend the use of the bi-
metallic damper. This component (part # 250-01741) is an 18"
section of Duravent pipe that is installed at the top of the
chimney, directly below the cap. It has a heat-activated damper
that helps reduce cold air from entering the cooling ducts while
the fireplace is not in operation.
Use Outside Air "P" Trap and Insulated Duct
We recommend putting in a "P" trap in the outside air duct (used to supply air to the firebox) to prevent air
circulation when the fireplace is not in use. A typical "P" trap design is shown in the illustration above. In
addition, you should insulate the outside air duct to help reduce air circulation when the fireplace is not in
use.
Daily Requirements for Homeowners
HUMIDITY – If the home is equipped with a humidistat, make sure it is set correctly. The chart below

to eliminate condensation on the front of the fireplace.
OTHER ITEMS
Make sure the bypass is shut when the fireplace is not in use.
Slide the air control fully closed when fireplace is not in use.
Minimize the use of exhaust fans in the home when the fireplace is not in use.
