8. 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 airfl ow.
• Inspect the blower wheel by removing the blower wheel access cover.
• 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 fl ow, 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. Install 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 space between the blower wheel and the
motor face. This space must be:
201CRD – 1/8” 301CRD – 1/8”
5. Install 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 the ignitor
Never test an ignitor by placing a screwdriver (or other metallic
object) across the high voltage clips. Check 40700 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.
Ceramic fi ber materials
The appliance may contain ceramic fi ber and/or fi berglass
materials. Ceramic fi ber materials, such as chamber liners, may
contain carcinogenic particles (chrystobalites) after exposure
to heat. Airborne particles from fi berglass or ceramic fi ber
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-fi tting clothing, gloves and eye protection.
Use a NIOSH N95 certifi ed respirator. This respirator meets
requirements for protection from chrystobalites. Actual job
requirements or NIOSH regulations may require other or ad-
ditional protection. For information, refer to the NIOSH website,
http://www.cdc.gov/niosh/homepage.html.
Ceramic fi ber removal: To prevent airborne dust, thoroughly
wet ceramic fi ber with water before handling. Place ceramic
fi ber materials in a plastic bag and seal to dispose.
Avoid blowing, tearing, sawing or spraying fi berglass or ceramic
fi ber 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.
