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. Refer to 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.
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.
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 17. 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.
