lOcATION Of The uNIT

Air conditioning Applications

If the furnace is used in conjunction with air conditioning, the fur-

nace shall be installed in parallel with or upstream from the evapora-

tor coil to avoid condensation in the heat exchanger. In a parallel in-

stallation, the dampers or air controlling means must prevent chilled 

air from entering the furnace. If the dampers are manually operated, 

there must be a means of control to prevent the operation of either 

system unless the dampers are in the full heat or full cool position. 

The air heated by the furnace shall not pass through a refrigeration 

unit unless the unit is specifically approved for such service.
The blower speed must be checked and adjusted to compensate for 

the pressure drop caused by the evaporator coil. Refer to page 18 of 

this manual,  for recommended wiring and electrical connections of 

the air conditioning controls.

combustion Air

If the furnace is installed in a closet or utility room, two openings 

must be provided connecting to a well-ventilated space (full base-

ment, living room or other room opening thereto, but not a bed-

room or bathroom). One opening shall be located above the level of 

the upper vent opening and one opening below the combustion air 

inlet opening in the front of the furnace. Each opening shall have 

a minimum free area of 1½ square inches per 1,000 Btu/h of total 

input rating of all appliances installed in the room.
For furnaces located in buildings of unusually tight construction, 

such as those with high quality weather stripping, caulking, windows 

and doors, or storm sashed windows, or where basement windows 

are well sealed, a permanent opening communicating with a well 

ventilated attic or with the outdoors shall be provided, using a duct 

if necessary. The duct opening shall have a free area of 1½ square 

inches per 1,000 Btu/h of total input rating of all appliances to be 

installed. When a furnace is installed in a full basement, infiltration 

is normally adequate to provide air for combustion and draft opera-

tion. Furnace rooms under 65m³ (2295 ft

3

)  should automatically be 

treated as confined space.

chimney Venting

The flue pipe should be as short as possible with horizontal pipes 

sloping upward toward the chimney at a rate of one-quarter inch to 

the foot. The flue pipe should not be smaller in cross sectional area 

than the flue collar on the furnace. The flue pipe should connect to 

the chimney such that the flue pipe extends into, and terminates 

flush with the inside surface of the chimney liner. Seal the joint 

between the pipe and the lining. The chimney outlet should be at 

least two feet above the highest point of a peaked roof. All unused 

chimney openings should be closed. Chimneys must conform to 

local, provincial or state codes, or in the absence of local regulations, 

to the requirements of the National Building Code.

NOTICE

THE FURNACE IS APPROVED FOR USE WITH TYPE L 

VENT OR EQUIVALENT.

!

  

CAUTION

CHIMNEY VENTED VERSIONS OF THE FURNACE 

MUST BE CONNECTED TO A FLUE HAVING SUFFI-

CIENT DRAFT AT ALL TIMES TO ENSURE SAFE AND 

PROPER OPERATION OF THE APPLIANCE.

NOTICE

THE RECOMMENDED FLUE DRAFT PRESSURE IS 

-0.02 IN. W.C. (See 

Figure 2

)

The flue pipe must not pass through any floor or ceiling, but may 

pass through a wall where suitable fire protection provisions have 

been installed. Refer to the latest edition of CAN/CSA B-139 for 

rules governing the installation of oil burning equipment. In the 

United States, refer to the latest edition of NFPA 31 for regulations 

governing the installation of oil burning equipment.

See Page 11, (Oil Burner Setups) of this manual for burner set-up.
