2.4.1Combustion Air Supply
Air inlets of at least 200 square inches free area (1.5 in2/1000Btu) must be provided to the room occupied by the wood fired or oil fired boiler. These fresh air inlets must provide or allow free access of fresh outside air to the boiler. At no time, or under any circumstances can a wood or oil burning appliance, be starved of combustion air.
The appliance must at all times be able to maintain the approved stack draft. The barometric draft regulator must be installed on the boiler smoke pipe in the same room or at least in such a way that there is unrestricted free passage of air between the combustion air inlet to the boiler or burner and the barometric draft regulator.
It is important to provide adequate combustion air to the boiler. It may be necessary to add a ventilator to an exterior wall of a closed boiler room or an airtight basement.
Operating a wood or oil fired appliance with inadequate combustion air could be hazardous.
