Air Band Adjustment
Air band adjustment may be necessary based on fuel and location.
1) To adjust air band, loosen screw and rotate air-band open or closed until desired ame is attained.
2) Re-tighten Screw to re-secure Air Band in newly adjusted position.
Burner Flame Adjustment
Due to the difference of ow in nozzles even those of the same size it will be necessary to adjust the
pump pressure High and Low when changing nozzles. When making adjustments always start with the
high setting. (See Figure 4A)
1. Set Air Band at 1.25 to start.
2. Start the Radiant Heater and allow to run for 5 minutes.
3. Check the heat transfer disk on the front of the heater is it glowing bright orange or is it dull. This
can best be seen in a shady location and not in direct sun.
4. If it is bright orange check the side prole of the transfer disk and make sure no ames are coming
through the openings of the transfer disk.
5. If ames are coming through the face of the transfer disk the pressure is too high and will need to be
turned down.
6. If the heat transfer is dull orange the pressure will need to be turned up to achieve the desired glow.
7. Make sure the ames do not come through the face of the heat transfer disk.
Turning the adjustment screw clockwise will increase the fuel pressure. Turning the adjustment screw
counterclockwise will decrease the fuel pressure. The top screw changes the pressure for the low setting,
and the bottom changes it for the high setting (See Figure 4A).

Annual Maintenance and Service Procedures
NOTE: Maintaining and Cleaning your heater at the end of each heating season is important to prolong
the life of your radiant heater and keep it operating in peak condition.
Replace lter element after 200 hours (approximately 12 tanks of fuel).
Clean the blower wheel
The blower wheel accumulates dust and debris from normal operation. You will need to clean the wheel
blades periodically to prevent reduction in airow.
1. Inspect the blower wheel by removing the blower wheel access cover.
a. To remove the cover, open the ignitor plate and loosen the blower wheel access cover screw
about three turns.
b. Inspect the blower wheel to see if it needs to be cleaned. Dirt and lint on the wheel reduce air
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.
3. Replace motor/wheel in blower housing and secure with the two bolts.
4. 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.
WARNING: Turn off power to appliance when servicing burner. Failure to comply could result
in severe personal injury, death or substantial property damage.

User's Manual: Radiant Heater
WARNING: CERAMIC FIBER MATERIALS
The appliance may contain ceramic ber and/or berglass materials. Ceramic ber materials,
such as chamber liners, may contain carcinogenic particles (chrystobalites) after exposure
to heat. Airborne particles from berglass or ceramic 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-tting
clothing, gloves and eye protection.
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.
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
Motor maintenance
The PSC motor is constructed with permanently-lubricated bearings, and requires no oiling.
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.
Use a NIOSH N95 certied 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 ber removal
To prevent airborne dust, thoroughly wet ceramic ber with water before handling. Place ceramic ber
materials in a plastic bag and seal to dispose. Avoid blowing, tearing, sawing or spraying berglass or
ceramic 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.
