PLACEMENT & VENTING
Furnace installation shall conform to the required installation code for oil-fired equipment (USA:
NFPA 31, Canada: CSA B139).
FLOOR SUPPORT COMBUSTIBLE – If required, support furnace on five (5) concrete
blocks. Make sure the center of the furnace base is supported.
Approved for installation on combustible floors in the upflow position and
downflow position (with the optional sub-base). Not approved for
installation on combustible floor in horizontal applications. For horizontal
applications, use railing type support (not supplied) to keep the furnace
in position. Make sure that all clearances are respected.
CHIMNEY/VENT
Connect the furnace to a chimney/vent system of size and condition
required by the NFPA 31 (USA) or CSA B139 (Canada) code. Furnace
is approved for factory built chimney type “L” vents. Breech is certified
for 5” vent pipe. Keep vent/flue pipe as short as possible with a
minimum upward slope of ¼’’ per foot. Vent/flue pipes MUST NOT pass
through a ceiling. Maximum flue gas temperature is 575°F.
CONDENSATION
If you have condensation in your chimney, make sure that the
chimney size is according to the tables in CSA B139 / NFPA 31.
The temperature at the entrance of the chimney can be increased
by insulating the flue-pipe between the furnace and the chimney
base. If this is not sufficient, consider cutting or removing some
flue baffles in the furnace. BE AWARE THAT REMOVING BAFFLES
REDUCES THE UNIT EFFICIENCY AND A MODIFIED UNIT IS NO
LONGER ENERGY STAR APPROVED.
COMBUSTION &
Install openings and ductwork to the furnace room providing fresh
VENTILATION AIR outside combustion and circulation air for cooling the furnace casing, as
installation code requires (USA NFPA 31, Canada CSA B139). If
installed in a closed room, provide two free air ventilation openings of at
least 8” x 12” (96 sq. in.) free flow area near ceiling and floor. Oil burners
must have sufficient air to allow vent systems to operate properly.
DRAFT
Use approved draft control supplied for 5” pipe. Set specified draft
minimum pressure of -0.01” wc.
ELECTRICAL
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.
CLEARANCES
Before placing unit, review installation clearances as shown on furnace
operating decal or section PRODUCT INFORMATIONS.
LOCATION
Install the furnace close to chimney and central to ductwork.
