2.8.2 Burner with Outdoor Combustion Air Kit
Certain burners are designed to function with combustion air
taken directly from the outside. Follow the instructions
provided with the burner, the fresh-air supply kit or the side-
wall venting kit.
2.9
OIL TANK
WARNING
Fire and explosion hazard.
Use only approved heating type oil in this furnace.
DO NOT USE waste oil, used motor oil, gasoline or
kerosene.
Use of these will result in death, bodily injury and/or
property damage.
CAUTION
When a 0.75 USGPH or smaller nozzle is used, a 10 micron
or finer filter, must be installed on the oil supply line to the
furnace inside the building where the unit is located.
This is a requirement in order for the heat exchanger warranty
to remain in force.
Check your local codes for the installation of the oil tank and
accessories.
At the beginning of each heating season or once a year,
check the complete oil distribution system for leaks.
Ensure that the tank is full of clean oil. Use No.1 or No.2
Heating Oil (ASTM D396 U.S.) or in Canada, use No.1 or No.2
Furnace Oil.
A manual shut-off valve and an oil filter shall be installed in
sequence from tank to burner. Be sure that the oil line is clean
before connecting to the burner. The oil line should be
protected to eliminate any possible damage. Installations
where the oil tank is below the burner level must employ a
two-pipe fuel supply system with an appropriate fuel pump. A
rise of 2.4 m (8') and more requires a two stage pump and a
rise greater than 4.9 m (16') an auxiliary pump.
Follow the pump instructions to determine the size of pipe
needed in relation to the rise or to the horizontal distance.
2.10

DUCTING

WARNING
Poisonous carbon monoxide gas hazard.
DO NOT draw return air from inside a closet or utility
room. Return air MUST be sealed to the furnace
casing.
Failure to properly seal ducts can result in death,
bodily injury and/or property damage.
The ducting must be designed and installed according to
approved methods, local and national codes as well as
good trade practices.
When ducting supplies air to a space other than where
the furnace is located, the return air must be sealed and
also be directed to the space other than where the
furnace is located.
2.10.1 Air filter
A properly sized air filter must be installed on the return
air side of the unit. Refer to the Technical Specifications,
Table 6 for the correct dimensions. Also refer to Section
2.2 and the instructions supplied with the filter.
2.11 SUPPLY AIR ADJUSTMENTS
(4 SPEED MOTORS)
On units equipped with 4-speed blower motors, the
supply air must be adjusted based on heating/air
conditioning output and the static pressure of the duct
system. For the desired air flow refer to the following table
as well as the air flow tables based on static pressure in
the Technical Specifications section of this manual.

To effect the adjustment, the RED (for heating) and BLUE
(for cooling and heat pump) wires can be changed on the
motor. Also, refer to the position of the wires on the
electronic board of the unit and consult the wiring
diagrams. If the heating and air conditioning speeds are
the same, the RED wire must be moved to "UNUSED
LEADS" on the electronic board and the jumper provided
with the BLUE wire must be used between the "HEAT"
and "COOL" terminals.
The blower start/stop delays can be adjusted by
positioning the DIP switches on the electronic board as
shown in the following figures. The recommended blower
ON delay is 60 seconds and blower OFF delay 2 minutes:
