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,
creating 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.
