FIREBOX BRICK REPLACEMENT
This furnace comes from the factory with the firebrick in-
stalled. However, if brick replacement is necessary, follow
these instructions. Before furnace operation, remove the
brick retaining strip. This piece is used during shipping to
reduce brick damage.
For model 1602, there are 6 full brick and 1 half brick per
side. Install the half brick first by putting the bottom of the
brick in first and let it rest against the firebox side and fire
grates. Then slide it to the rear. After that, install the #2, #3,
#4, #5 & #6 brick, sliding the 6th brick forward to allow for
the 7th brick. Repeat for opposite side.
For model 1802, there are 8 full brick and 1 half brick per
side. Install the brick in the same manner as previously in-
structed for the model 1602.
NOTE: Prior to operation, be sure to remove the brick
retaining strips.

FIREBRICK AND BAFFLE REPLACEMENT
BAFFLE/BRICK REPLACEMENT
If baffle replacement is necessary, slide the baffle out until
you can access the nuts thru the flue outlet. Once the
nuts have been removed, slide the baffle off the rod and
thru the opening in the firebrick. You may have to remove
one of the firebrick to make baffle removal easier.
For model 1602, there are 4 full brick and 1 half brick in the
top of the furnace. Install the brick by inserting one end of
the brick angled upward and then allowing the opposite
end to rest on the firebox lip. Lay the brick between the
spacer and firebox back. Slide the baffle to the rear and
let it rest on that half brick. After installing brick #2 in the
front, install #3 and slide it under the baffle. Finally install
bricks #4 and #5.
For model 1802, there are 6 full brick in the top of the fur-
nace. Install the brick in the same manner as previously
instructed above.
