APPENDIX 4 - INSTALLING THE FRESH AIR INTAKE KIT
During operation, the fireplace requires fresh air for combustion and draws air out of the house. It may starve
other fuel burning appliances such as gas or oil furnaces. As well, exhaust fans may compete for air, causing
negative pressure in the house, resulting in smoke entering the house from the fireplace. This situation is
aggravated in modern airtight houses. To overcome this problem, we strongly recommend that you bring fresh
air to the fireplace. Check with local authorities having jurisdiction in your area, it may be mandatory.
Fresh air intake kit installation
Follow these instructions to install a fresh air intake kit:
The insulated flexible pipe length (D) should be sufficient
and have a configuration to avoid condensation.

extreme wind and away from automobile exhaust fumes, gas meter and other vents.
