Model EZ-1/2/3 oil burners — Instruction manual

8.  Maintenance procedures

Maintenance/service procedures

  Turn off power to appliance when servicing burner. Failure to comply 

could result in severe personal injury, death or substantial property 
damage.

Cleaning blower wheel

1.  The blower wheel accumulates dust and debris from normal operation. You will 

need to clean the wheel blades periodically to prevent reduction in airflow.
•  Inspect the blower wheel by removing the blower wheel access cover. See 

Figure 18.

•  To remove the cover, open the ignitor plate and loosen the blower wheel 

access cover screw about three turns.

•  Inspect the blower wheel to see if it needs to be cleaned. Dirt and lint on 

the wheel reduce air flow, and must be removed if the burner is to operate 
correctly.

2.  To clean blades, remove the two bolts securing the motor to blower housing.

a.  Slide the motor out and rotate to remove and access blower wheel.
b.  Use a brush and vacuum to clean each blade and the blower housing 

interior.

c.  Replace motor/wheel in blower housing and secure with the two bolts.
d.  Push wire slack back into junction box.

Replacing blower motor or wheel

1.  If either the blower wheel or motor must be replaced, remove the two bolts 

securing the motor to housing.

2.  Disconnect the motor wires in the burner junction box.
3.  Loosen the Allen screw securing the blower to the motor shaft and remove the 

wheel.

4.  When assembling the replacement assembly, slide the wheel onto the motor 

shaft and use feeler gauges to set a space of 3/64 inch between the blower 
wheel and the motor face.

5.  Replace the motor/wheel assembly in the housing, wire the motor leads and 

secure the motor with the two bolts.

Motor maintenance

•  The Carlin PSC motor is constructed with permanently-lubricated bearings, 

and requires no oiling. Should you replace the original motor with another type 
of motor, occasional oiling may be required, depending on motor design and 
manufacturer’s recommendations.

•  Any time you replace a component or disassemble any part of the burner for 

service/maintenance, perform a complete operational test after reassembly to 
verify the burner operates correctly. Failure to verify operation could result in 
severe personal injury, death or substantial property damage.

Checking ignitor

 

Never  test  an  ignitor  by  placing  a  screwdriver  (or  other  metallic 
object) across the high voltage clips. Check 40700 & 40900 ignitors 
only by observing spark at appliance ignition electrodes, with fuel 
supply OFF. Using any other method could cause ignitor damage 
and severe personal injury.

1.  Checking 41000 ignitors only:

•  Disconnect electrical power to burner.
•  Remove hold down clips or screws. Lift ignitor mounting plate to the full-

open position. Set high voltage clips to a ½” to ¾” gap.

•  Carefully energize ignitor and check for spark arcing at the high voltage 

terminals. If spark jumps the gap, ignitor is good.

Ceramic fiber materials

  The appliance may contain ceramic fiber and/or fiberglass materi-

als. Ceramic fiber materials, such as chamber liners, may contain 
carcinogenic particles (chrystobalites) after exposure to heat. Airborne 
particles from fiberglass or ceramic fiber components have been 
listed as potentially carcinogenic by the State of California. Take the 
following precautions when removing, replacing and handling these 
items.

 

Avoid  breathing  dust  and  avoid  contact  with  skin  or  eyes. Wear 
long-sleeved, loose-fitting clothing, gloves and eye protection. Use 
a NIOSH N95 certified respirator. This respirator meets requirements 
for protection from chrystobalites. Actual job requirements or NIOSH 
regulations may require other or additional protection. For information, 
refer to the NIOSH website, http://www.cdc.gov/niosh/homepage.
html.

 

Ceramic fiber removal: To prevent airborne dust, thoroughly wet 
ceramic  fiber  with  water  before  handling.  Place  ceramic  fiber 
materials in a plastic bag and seal to dispose.

 

Avoid blowing, tearing, sawing or spraying fiberglass or ceramic fiber 
materials. If such operations are necessary, wear extra protection 
to prevent breathing dust.

 

Wash work clothes separately from other laundry. Rinse clothes 
washer  thoroughly  afterwards  to  prevent  contamination  of  other 
clothing.

 

NIOSH First aid procedures:

 

Eye exposure — irrigate immediately

 

Breathing — fresh air.
