3.4 PLACEMENT, VENTING & VENTILATION
Furnace installation shall conform to the required installation code for oil-fired
equipment (USA: NFPA 31, Canada: CSA B139).
FLOOR SUPPORT
If required, support furnace on 5 concrete blocks. Make sure the
NON-COMBUSTIBLE
center of the furnace base is supported. For a furnace installed on
a combustible floor, a fire-resistant heat shield, which satisfies the
requirements of the authorities having jurisdiction, must be placed
between the furnace base pan and the floor to create a non-
combustible base. The floor must be strong enough to carry the
weight.
CLEARANCES
Before placing unit, review installation clearances as shown on
furnace operating decal
or “GENERAL SPECIFICATIONS”.
LOCATION
Install the furnace close to chimney or vent and central to
ductwork.
CHIMNEY/VENT
Connect the furnace to a chimney/vent system of size and
condition required by the installation code. THIS FURNACE IS
APPROVED FOR FACTORY BUILT CHIMNEY TYPE “A” OR
TYPE “L” VENT. See operating decal for approved vent/flue pipe
sizes. Maximum flue gas temperature is 575°F.

This Furnace is approved for Kerr Direct Vent.
WALL-VENTING
COMBUSTION &
Install openings and ductwork to the furnace room to provide fresh
VENTILATION AIR
outside combustion air and circulation air for cooling the furnace
casing as installation code requires (USA: NFPA31, Canada: CSA
B139). If installed in a closed room, provide two free air ventilation
openings of least 170sq. in. each free flow area near ceiling and
floor. Oil burners must have sufficient air to allow vent systems to
operate properly. See furnace operating decal. Not applicable to
Direct Vent installation.

Wire according to the National Electrical Code (Canadian
Electrical Code in Canada) or local codes. Use a separately fused
#12 electrical line directly from the service panel to the furnace
junction box. Install a manual shut off switch at the door or
stairway to furnace room so furnace can be shut off remotely.

See NFPA 31 (USA) or CSA B139 (Canada) code. Breech is
certified for 5” vent pipe. Keep vent/flue pipe as short as possible
with min. 1/4” per foot upward slope. Use approved fitting through
