Model EZ-1/2/3 oil burners — Instruction manual
Annual start-up & service
Perform the following
This burner must be started and serviced at least annually
by a qualified service technician. Failure to properly maintain
and service the burner could result in severe personal injury,
death or substantial property damage.
• Discuss burner/appliance operation with user to determine any problems
that may have occurred during the previous season and to verify user
is aware of proper operation and care of the burner/appliance.
• Review proper operation of the appliance/burner unit with the user.
• Turn off power to appliance.
• Remove combustion head assembly to clean and adjust if necessary.
(See procedure on page 10.)
• If the inside surface of the air tube and/or retention ring need to be
cleaned, clean them with a vacuum cleaner with brush attachment
while the combustion head assembly is out of the burner.
• Replace the oil nozzle with the correct size.
• Inspect and adjust the ignition electrodes and insulators per instructions
on pages 10 and 11 of this manual. Replace if proper spacing cannot
be achieved or if components are damaged.
• Close the housing cover plate and secure in place.
• Inspect the fuel line oil filter. Replace if necessary.
Oil line filters — Use a non-bypassing filter to prevent nozzle
plugging caused by poor oil filtration. Non-bypassing filters
prevent small foreign particles from bypassing the filter, a
common problem with fiber element type filters. Another
problem of some filters is the fiber from filter element tears
can break away and plug the nozzle or fuel unit.
• Perform the complete checkout procedures of pages 10 to 13, including
system inspection and checks.
• Inform the user of any problems found.
Verify burner/appliance operation
Check burner/appliance/controls operation
• Test operating and limit controls on appliance as specified in appliance
instructions.
• Check operation of the primary control by forcing lockout to occur.
For primary controls that enter latch-up after multiple lockouts, force
latch-up to occur as well. Reset primary control per control data sheet
instructions after each test.
• Start and stop the burner several times, allowing the primary control to
sequence through normal operation. Verify correct operation of burner
and primary control throughout.
Verify vent system operation
• Verify vent is operating correctly and flue products are properly ex-
hausted from building. If the building contains any exhaust fans or
conditions that could affect vent performance, check burner/appliance/
vent operation with exhaust fans (or other conditions) operating.
Combustion/ventilation air
• Verify combustion/ventilation air openings are not/will not be obstructed.
• Verify air opening louvers are full open.
• If louvers are motor-operated, verify motor and end switch are inter-
locked with appliance/burner wiring to prevent operation of the burner
if the air louvers are not fully opened.
Prepare burner for normal operation
• Cycle burner off with appliance controls.
• Turn off power to the appliance.
• Seal the appliance flue damper test opening.
• Verify all components and wires are in place and burner is ready for
operation.
• Restore power to the appliance.
Train the user
• Train the user to operate the burner and appliance under normal
conditions.
• Explain procedure to shut down burner/appliance when required.
• Review rear cover of this manual (and the appliance manual) with the
user.
• Verify the user is aware of all procedures specified in the manuals.
• Verify user will not store or use combustible liquids or materials or
contaminants in the vicinity of the burner/appliance.
