INSPECTING
AND CLEANING
MAINTENANCE
WARNING: Turn off heater and
let cool before cleaning.
CAUTION: You must keep
control areas, burner and
circulating air passageways of
heater clean. Inspect these areas
of heater before each use. Have
heater inspected yearly by a
qualified service person. Heater
may need more frequent cleaning
due to excessive lint from
carpeting, pet hair and bedding
material, etc.
CLEANING BURNER
INJECTOR HOLDER AND
PILOT AIR INLET HOLE
The air shutter slots allow the proper
amount of air to mix with the gas. This
provides a clean burning flame. Keep
these slots clear of dust, dirt, lint and
pet hair. Clean these air inlet slots prior
to each heating season. Blocked air
slots will create soot. We recommend
that you clean the unit every three
months during operation and have
heater inspected yearly by a qualified
service person.
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 PSI. Your local
computer store, hardware store or home
center may carry compressed air in a
can. You can use a vacuum cleaner in
the blow position. If using compressed
air in a can, please follow the
directions on can. If you don’t follow
directions on can, you could damage
the pilot assembly. NOTE: For
Townsend II See (Figure 11, page
12). For Hepplewhite See (Figure 14,
page 14). Removing access door and
top grates of your stove will make
cleaning easier.
1. Shut off unit, including pilot.
Allow unit to cool for at least thirty
minutes.
2. Inspect burner, pilot and slots in
air shutter for dust and dirt.
3. Using Phillips head driver loosen
set screw on air shutter and rotate
shutter toward rear of unit. NOTE:
Before rotating shutter mark the
position of shutter so you can
LOGS
If you remove logs for cleaning,
refer to Installing Gas Logs.
For
Townsend II
(Figure 13, page
13). For Hepplewhite (Figure 15,
page 15), to properly replace logs.
MAIN BURNER
Periodically inspect all burner flame
ports with the heater running. All
slotted burner flame ports should be
open with flame present. Some burner
flame ports may become blocked by
debris or rust, with no flame present. If
so, turn off heater and let cool. Either
remove blockage or replace burner.
Blocked burner flame holes will create
soot.
move it back to the correct position
after cleaning.
4. Opening the shutter as in step 3,
allows you to inspect the orifice.
After cleaning the area adjust air
shutter to the original position.
5. Blow air through the slots and
holes in the burner.
6. Blow air into the primary air holes
on the injector holder.
7. In case any large clumps of dust
have now been pushed into the burner
repeat steps 3 and 4.
Clean the pilot assembly also. A yel-
low tip on the pilot flame indicates
dust and dirt in the pilot assembly.
There is a small pilot air inlet hole
about two inches from where the pilot
flame comes out of the pilot assembly
(See Figure 22). With the unit off,
lightly blow air through the air inlet
hole. You may blow through a drink-
ing straw if compressed air is not
available.
