Pre-installation considerations

Codes and standards

• Install burner in accordance with NFPA 31, Stan­dard 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 au­thorities 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

supplied with burner.

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.

Control Supple-

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.

Combustion and ventilation
air openings

See appliance manual and

Burning Equipment

practice in Canada, refer to

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 (vol­ume of space less than 50 cubic feet per 1,000 Btuh
input of all appliances in space), two permanent open­ings 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 appli­ances 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 out­side 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.

• If QB-180 or QB-300 Oil Burner is
received separately for field installation,
proceed to page 5,

• If QB-180 or QB-300 Oil Burner is
received installed on the boiler, proceed
directly to page 8,

Fuel pumps and oil lines

General

All installations must comply with national or local
codes and ordinances.

Oil line must be piped properly to
avoid risk of serious personal injury,
death or substantial property damage.
Follow these recommendations:

• When installing oil lines, use
continuous runs of heavy-wall
copper tubing.

• Be sure all connections are airtight.
Flared fittings are recommended.
Do not use compression fittings.
Do not use Teflon tape.

• Use an oil filter of adequate size for
all installations. Install filter inside
building between tank shutoff valve
and burner. For easy servicing,
locate shutoff valve and filter near
burner.

• Long or oversized inlet lines may
require the pump to operate dry
during initial bleeding period. In
such cases, assist priming by
injecting fuel oil into pump gearset.

• Never exceed 3 psi pressure to inlet
side of pump. Pressure over 3 psi
may damage shaft seal and allow it
to leak oil.

port. Do not use easy flow air bleed valve. It contains
higher pressure than operating pressure.

Setting pump pressure with gauge in easy flow air bleed
valve will result in wrong operating pressure.

Average cutoff pressure is 120 psig. Check cutoff
pressure by installing pressure gauge in nozzle port of
fuel pump. Run burner for short time. Shut off burner.
Gauge shows cutoff pressure.

Figure 5 Fuel pump — Typical

Solenoid valve

Solenoid valve supplied in nozzle line is a non-delay
valve and provides instant oil supply shutoff to nozzle.

Vacuum gauge

Vacuum gauge may be installed in either of the ¼" inlet
ports. Vacuum is total of all pressure drops in system
from tank to pump inlet.

Two-pipe oil systems (Figure 7)

Use two-pipe installations when fuel must be lifted
greater than 8 feet.

Burner fuel pump — A single-stage pump is limited

to a fuel lift height of no more than 10 feet. For greater
lifts install a two-stage pump on the burner.

Fuel suction line vacuum must not exceed 12" Hg

for a single-stage pump or 17" for a two-stage pump.

Bypass plug must be used with two-pipe installations.

Remove plug from plastic bag attached to fuel pump.
Remove ¼" plug from return port. Insert bypass plug.
Attach return and inlet lines.

Weil-McLain Limited Warranty

for QB-180 and QB-300 Burners

RESIDENTIAL OIL-FIRED BURNERS

3-Year Limited Warranty

Weil-McLain warrants that its residential oil-fired burn­ers are free from defects in material and workmanship
for three years from the date of installation. If any parts
are found to be defective in manufacture, Weil-McLain
will provide replacement of such defective parts with
the following exceptions:

• nozzles

• cad cell

The provisions of this warranty for the above parts
are limited to 12 months from the date of installa­tion or 18 months from the date of manufacture,
whichever date occurs first.

This warranty does not cover:

1. Workmanship of any installer of Weil-McLain’s resi-
dential oil-fired burners. In addition, this warranty
does not assume any liability of any nature for un­satisfactory performance caused by improper in­stallation.

2. Filters, strainers or any other routine maintenance
part as supplied through the contractor.

3. Any costs for labor for removal and reinstallation
of the alleged defective part, transportation to Weil­McLain, if necessary, and any other materials nec­essary to perform the exchange.

4. Unsatisfactory performance or damage caused by
improper burner adjustments, control settings, care
or maintenance.

5. Burners operated with combustion air contami­nated externally by chemical vapors or with im­proper fuel additives.

This warranty extends only to the first retail purchaser
of the burner and only to a burner that has not been
moved from its original installation site.

THE WARRANTY DESCRIBED ABOVE IS IN LIEU
OF ALL OTHER WARRANTIES, EXPRESS OR IM­PLIED, INCLUDING BUT NOT LIMITED TO ANY
IMPLIED WARRANTIES OF FITNESS FOR A PAR­TICULAR PURPOSE AND MERCHANTABILITY.
WEIL-McLAIN EXPRESSLY DISCLAIMS AND EX­CLUDES ANY LIABILITY FOR CONSEQUENTIAL,
INCIDENTAL, INDIRECT OR PUNITIVE DAMAGES
FOR BREACH OF ANY EXPRESS OR IMPLIED
WARRANTY.

For prompt warranty claims, notify the installer who,
in turn, will notify the Weil-McLain distributor from
whom he purchased the burner. If this action does not
result in warranty service, contact Weil-McLain Con­sumer Relations Department, 500 Blaine Street, Michi­gan City, Indiana 46360-2388, with details in support
of the warranty claim. Alleged defective part or parts
must be returned through trade channels in accordance
with the Weil-McLain procedure currently in force for
handling returned goods for the purpose of inspec­tion to determine cause of failure. Weil-McLain will
furnish new part(s) to an authorized Weil-McLain dis­tributor who, in turn, will furnish the new part(s) to
the heating contractor who installed the burner. If you
have any questions about the coverage of this warranty,
contact Weil-McLain at the address above.
