K. BURNER INSTALLATION
The burner mounts to the furnace on three mounting bolt studs, located on the burner mounting
plate, in the lower portion of the vestibule, directly in front of the heat exchanger.
The burner insertion depth has been fixed by the factory for the design-specified, combination of
the air tube length and the combustion chamber used with the furnace. The combustion chamber is
pre-positioned during the assembly process and held in place by the drum and mounting plate. The
burner insertion depth is not field-adjustable.
Should access to the chamber be necessary, refer to the exploded diagram, in the back of this
manual, to identify replacement parts.
To install and ready the burner for firing, follow the steps below for both furnace models.
1.
With electrical power connected to the furnace, turn off all electrical power to unit.
2.
Remove the front lower access panel.
3.
Mount the burner to the furnace. Install the flange gasket over the mounting studs and
secure the burner flange to the furnace using hex head machine screw nuts, provided in the
Parts Kit.
4.
Connect the red and white wires from the burner harness to the black, red and white
burner power leads found underneath the primary control. Then connect the two yellow
wires to the “T & T” terminals on the front of the primary control.
For the oil burner installation only:
5.
Determine whether an oil return line is required and connect the fuel oil piping to the
burner oil pump through the base of the unit.
6.
Turn on electrical power to the furnace. Cause or simulate a “call for heat” to bleed air
from the oil line at the oil pump. (Temporarily, connect the two thermostat leads to
cause the oil pump to run.)
7.
With all oil shutoff valves open, open the air-bleed valve on the oil pump and capture
the oil flow in a container until all traces of air in the line are gone.
8.
Close the air-bleed valve. Check for and correct any oil leaks. The furnace is now
ready for burner adjustment. Refer to the following “BURNER OPERATION AND
ADJUSTMENT”
section.
L. BURNER OPERATION AND ADJUSTMENT
:
NEVER burn garbage or refuse in the furnace. NEVER try to ignite oil or gas by
tossing burning papers or other material into your furnace.
:
If you do not follow these instructions exactly, a fire or explosion may result
causing personal injury, loss of life or property damage.
