COMBUSTION AIR
Insure adequate combustion air allowing for all other exhausting type appliances in the dwell-
ing (range hoods, dryers, etc). Outside combustion air can be connected directly to the com-
bustion air inlet on either side of the lower front cover. Cut an opening 3 1/2" x 9 1/2" (Fig 1A).
Use a 4"x10" to 6" round boot to connect outside air duct. Minimum duct for outside air is 6"
with not more than 2 90o elbows in line, keep this outside air line as short as practical. If you
do not use outside combustion air you must cover the opening cut in the lower front cover
with the mesh screen provided in the furnace accessory kit.
LOCATION RE FLUE
The Chimney must be an approved chimney for use with solid fuel fired appliances, It must be
in good repair, free from leaks and obstructions. If using a masonry chimney, it must meet the
minimum standards of the building code of Canada.
The wood flue must always enter the
chimney below the oil flue. You must comply with the local authority having jurisdic-
tion and CSA installation standard B365-M87.
DO NOT OPERATE THE VC120 WITH A
DRAFT OF OVER .06 INCHES WATER COLUMN. HIGHER DRAFT LEVELS MAY CAUSE
THE FIRE TO BURN OUT OF CONTROL AND CREATE A FIRE HAZARD.
Flue pipe between the furnace and the chimney should be as short and direct as possible and
have a minimum rise of 1/4" per running foot. The chimney connector must be attached to
either an approved masonry chimney or one of the listed factory built chimneys suitable for
use with solid wood fuel. All joints must be tight and fastened with sheet metal screws. Place
the small (crimped) end of the pipe into the furnace collar and into each preceding length of
pipe to insure that any creosote which might form will run back down into the furnace see fig
10 below..
WARNING: Chimney connector is to be used only within the room, between the stove
and ceiling/wall. Never use a chimney connector to pass through a combustible ceil-
ing or wall. Always maintain the minimum clearances to combustibles as required by
the applicable building codes.
Recommended draft is .04 in. water COLUMN. It is unsafe
to operate the furnace with more than .06 in. water column draft. Use a barometric control if
necessary to achieve this.
