Pre-installation considerations
Codes and standards
•
Install burner in accordance with NFPA 31, Stan-
dard for Oil-Burning Equipment and all local codes
and regulations of authorities having jurisdiction.
In Canada, refer to CSA B139, Installation Code for
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
ment

Underwriters Laboratories has certified this burner
to comply with ANSI Standard 296.6 and has listed
it for use with No. 1 or No. 2 fuel oil as specified in
ASTM D396.
Chimney or vent
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

Control Supple-
supplied with burner.
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.
Combustion and ventilation
air openings
See appliance manual and
NFPA 31
for details. For recommended
Burning Equipment
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),
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.
