1.8 ELECTRICAL POWER FAILURE (Fig S101-3)
If no one is home during a power failure, the damper will automatically close and some
gravity heating will take place. Combustion air will continue to enter through the
secondary air holes and a fire should be maintained.
IMPORTANT – This furnace is CSA certified for operation under Power Failure only if
optional gravity air inlet kit is installed.
For optimum heating during a power failure follow the procedure listed below:
For Power Failure operation remove the power failure gravity air inlet cover before
starting or refueling during power failure. The cover is an option available from your
KERR dealer. The kit must be installed on the cabinet side directly opposite to the entry
of the blower or oil furnace “S” connection ductwork.
Manually open the blower compartment access door of wood or connected oil furnace
to allow gravity flowing air to all areas. (Check with your installer).
Place a coin under the damper flap in such a way that it will fall clear when power is
restored.
Maintain a careful watch on the furnace temperature. If it should exceed 200º F (95º C)
close the damper door.
Do not leave the furnace unattended in this position.
Refuel frequently with small loads to maintain a small fire at ½ normal maximum
volume.
Do not expect to maintain maximum comfort under no power conditions.
Do not allow anyone who is unfamiliar with the operation of the furnace to attend it
during a power failure.
