For many people, a wood fire is as much a part of the holiday season as lights, decorated trees, and gift giving. Whether the wood fire is a supplemental or principal source of heat, it is extremely important that it be safe and efficient, says the Minnesota Department of Commerce.
Combustion air is a major consideration.
Wood-burning fireplaces and stoves use large amounts of air in the combustion process. Without an outdoor air inlet, the wood fire will take combustion air from the indoors, creating the potential of dangerous backdrafting of gases from the stove or fireplace or from a furnace, water heater, or other fuel-burning appliance in the home. If you do not have an outdoor air inlet for your stove or fireplace, you can install one yourself. For instructions on installing a combustion air inlet, call the Department's Energy Information Center at the number below and ask for a free copy of the Combustion Air guide. Operating a stove or fireplace properly reduces fire hazards.
