2.3 Locating the Furnace (Fig S101-1, Fig S101-4)
The location of the furnace must be as close as possible to the tile-lined brick chimney,
or factory-built solid-fuel approved chimney (ULC S629). Keep in mind also the day-to-
day operation, and place for ease of fueling and cleaning. KERR recommends
installation if possible, in a central location in relation to the outlet registers and the use
of large warm air ducts to improve heat distribution during a power failure.
It is important to provide adequate combustion air to the furnace. It may be necessary
to add a ventilator to an exterior wall of a closed furnace room or an airtight basement.
The furnace must be installed so that the clearances as shown in Fig S101-1, or those
of local authorities are met. If the furnace must be installed on a combustible floor, a
non-combustible base must be built as shown in Fig S101-4. Two layers of hollow
masonry block (4” thick) are placed at right angles to each other so that the ventilation
holes of one layer are opposite to those of the other layer. Also there must be a
minimum of one layer of fireproof board and one layer of 26 gauge galvanized metal
beneath the masonry blocks. This base must extend beyond the furnace to a minimum
distance of 18 in (457 mm) in front and 8 in. (204 mm) on all sides.
2.4.1 Combustion Air Supply
Air inlets of at least 200 square inches free area (1.5 in
2
/1000Btu) must be provided to
the room occupied by the wood fired or oil fired furnace. These fresh air inlets must
provide or allow free access of fresh outside air to the furnace. 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 furnace 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 furnace or burner and the barometric draft regulator.
It is important to provide adequate combustion air to the furnace. It may be necessary
to add a ventilator to an exterior wall of a closed furnace room or an airtight basement.
Operating a wood or oil fired appliance with inadequate combustion air could be
hazardous.
