CLEANING AND MAINTENANCE

WARNING: Turn off heater and let cool before
servicing.
For maintenance of the inside cabinet or to access the
burner and pilot assembly for cleaning or service. Remove
the four screws(two located on each side) that secure
the front shell to the unit (Figure 6). Gently lift up on the
front shell to disengage the hooks and pull forward to
remove it. You will now be able to access all of the internal
components of the appliance.
CAUTION: You must keep control areas, burner and
circulation air passageways of heater clean. Inspect these
areas of heater before use. Have the heater inspected
yearly by a qualified service person. Heater may need
more frequent cleaning due to excess lent from carpeting,
bedding material, pet hair, etc.
Make sure grille guard is in place before running heater. If
screen or grille guard is removed for servicing it must be
replaced prior to operating the heater.
WARNING: Failure to keep the primary air opening(s)
of the burner(s) clean may result in sooting and
property damage.
CLEANING ODS/PILOT AND BURNER
•
Use as vacuum cleaner, pressurized air or small soft
bristled brush to clean.
CLEANING BURNER PILOT AIR HOLE INLET
We recommend that you clean the unit every 2,500 hours
of operation or every three months. We also recommend
that you keep the burner tube and pilot assembly clean and
free of dust and dirt. To clean these parts we recommend
using compressed air no greater than 30 psig.
This can be done by using a vacuum cleaner in the blow
position or using compressed air in a can. If using canned
air please follow the directions on the can. If you don't
follow directions on the can you could damage the burner
or pilot assembly. In addition, the directions below should
also be followed.
1. Shut off the unit, including the pilot. Allow the
unit to cool for at least thirty minutes.
2. Inspect burner and pilot for dust and dirt.
3. Blow air through the port/slots and holes in the
burner.
A yellow tip on the pilot flame indicates dust and dirt in the
pilot assembly. To clean the pilot assembly find the small
pilot air inlet hole about two inches from where the pilot
flame comes out of the pilot assembly (see figure 16). With
the unit off, lightly blow air through the air inlet hole. You
may blow through a drinking straw if compressed air is not
available.
