Oil Tank and Piping
PLACEMENT & VENTING
Furnace installation shall conform to the required installation code for oil-fired equipment
(USA: NFPA 31, Canada: CAN/CSA B139).
FLOOR SUPPORT COMBUSTIBLE – If required, support furnace on five (5) concrete blocks.
Make sure the center of the furnace base is supported. For a furnace
installed on a combustible floor, consult the applicable code and authorities
having jurisdiction on this application. The floor must support the weight.
CHIMNEY/VENT Connect the furnace to a chimney/vent system of size and condition required
by the NFPA 31 (USA) or CAN/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 min. 1/4” per foot
upward slope. Vent/flue pipes MUST NOT pass through a ceiling. Maximum
flue gas temperature is 575°F.
PRESENCE OF CONDENSATION
IN THE CHIMNEY OR FLUE PIPE
Presence of condensation in your chimney or flue pipe is not normal, all
necessary precautions should be taken to prevent condensation build-up in the
flue pipe and inside the chimney. Make sure that the chimney size is according
to the tables in CAN/CSA B139 / NFPA 31.
Note: Base temperature — the temperature of the flue gases at the base of
the chimney flue, measured within the vent at the base tee or vent connector
thimble, with the barometric damper shut, after the appliance flue-gas
temperature has stabilized.
