Motor maintenance
The PSC motor is constructed with permanently-lubricated bearings, and requires no oiling.
CAUTION: 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.
WARNING: CHECKING IGNITOR
Never test an ignitor by placing a screwdriver (or other metallic object) across the high voltage
clips. Check the 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.
Carefully energize ignitor and check for spark arcing at the high voltage terminals. If spark jumps the
gap, ignitor is good.
Tank maintenance
If it becomes necessary to drain the fuel tank there is a drain plug located on the bottom of the tank.
WARNING: CERAMIC FIBER MATERIALS
The appliance may contain ceramic fiber and/or fiberglass materials. 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.
