BE AWARE THAT MODIFYING OR REMOVING BAFFLES REDUCES
THE UNIT’S EFFICIENCY.
Note: See
Base temperature
definition inside NFPA-31 and CAN/CSA
B139 codes.
The base temperature of the chimney shall be measured after the unit has
been in operation for a minimum of 5 minutes or long enough for the flue
gas temperatures to have reached equilibrium. Install a thermometer in
the vent pipe as close as possible to the entry point of the vent pipe into
the chimney, at the base “T”, the barometric damper must be completely
shut and the flue gas temperature reading is stable. The base temperature
must be within the values indicated in table 1 or 2 of the CAN/CSA B139
code for Canadian installations or values indicated in the NFP-31 code for
USA installations.
ELECTRICAL
Wire according to the National Electrical Code (Canadian Electrical Code
in Canada) or local codes. Use a separately fused #12 electrical line
directly from the service panel to the furnace junction box. Install a
manual shut-off switch at the door or stairway to furnace room so
furnace can be shut off remotely.
COMBUSTION &
VENTILATION AIR
Oil-fired appliances shall be connected to vents having sufficient draft at all
times to provide safe and proper operation of the appliance.
Oil combustion appliances must be installed only when sufficient
combustion air is available to ensure appropriate combustion and
circulating air temperatures as per NFPA-31 code in the USA and CAN/CSA
B139 code in Canada. If the construction of the building cannot allow for
enough air infiltration through natural infiltration of the building to satisfy
combustion air requirements and circulating air requirements outside air
must be brough inside the space surrounding the oil combustion appliance.
ADDITIONAL
CONSIDERATIONS
Keep clear space around the appliance. Do not stack items or box in the
appliance within the required clearances to combustibles.
To ensure proper operation of the appliance it is important to maintain a
free flow of air through the return air registers.
Contact an authorized service representative before any remodeling of the
residence to ensure that the furnace is sized properly and the heating
ducts are suitable for any new additions.
