Oil-Burning Equipment. Regulations of these au-
thorities take precedence over instructions in this
manual.

All wiring must comply with National Electrical
Code and local ordinances; in Canada, CSA C22.1
Canadian Electrical Code Part One and any local
codes. Refer to wiring diagram in
Control Supple-
ment

Pre-installation considerations
1
Combustion and ventilation
air openings
See appliance manual and
NFPA 31
,
Standard for Oil-
Burning Equipment
for details. For recommended
practice in Canada, refer to
CSA Standard B139
.
Adequate combustion and ventilation
air must be provided to assure proper
combustion and reduce risk of flue gas
leakage and carbon monoxide
emissions, leading to severe personal
injury or death.
When the boiler is installed in a confined space (vol-
ume of space less than 50 cubic feet per 1,000 Btuh
input of all appliances in space),
two
permanent open-
ings must be provided:
•
One near the top of the enclosure
•
One near the bottom.
•
Each opening must have a free area of not less than
one (1) square inch per 1,000 Btuh (140 square inch
per gph), of the total input rating of all the appli-
ances in the space.
When building is of unusually tight construction, has
a kitchen ventilating system, exhaust fans, clothes dryer
or vented fireplaces, it may be necessary to duct out-
side air directly to the burner in order to support clean
combustion. Weil-McLain QB-A1 Outside Air Kit, part
number 644-500-056, provides outside air directly to
the burner.
Chimney or vent
Inspect existing chimney or vent
before installing new burner. Failure to
do the following will cause severe
personal injury or death.
•
Clean chimney, including removal
of blockage.
•
Repair or replace damaged pipe or
liner.
•
Repair mortar and joints.
Set the over-fire draft to the appliance manufacturer’s
recommended setting if available, or to -0.01" to -0.02"
water column. Install barometric control in breeching,
per control manufacturer’s instructions, when excess
draft needs to be relieved or to comply with applicable
codes and regulations. Use draft gauge to adjust proper
opening.
