FIREBOX BRICK REPLACEMENT
This furnace comes from the factory with the rebrick 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 rst by putting the bottom of the
brick in rst and let it rest against the rebox side and re
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.
NOTE: Prior to operation, be sure to remove the brick
retaining strips.

FIREBRICK AND BAFFLE REPLACEMENT
BAFFLE/BRICK REPLACEMENT
If bafe replacement is necessary, slide the bafe out until
you can access the nuts thru the ue outlet. Once the
nuts have been removed, slide the bafe off the rod and
thru the opening in the rebrick. You may have to remove
one of the rebrick to make bafe 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 rebox lip. Lay the brick between the
spacer and rebox back. Slide the bafe 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 bafe. Finally install
bricks #4 and #5.
