Assembling Filter Box
The cold air return filter box can be assembled
with the filter frame on either side or the back, pro-
vided there is access to the combustion blower and flue
area.
It is not recomended that the filter frame be installed
on the same side as the ash door due to the need to
access the combustion blower, filter, and flue pipe for
service.
1. Place the bottom on the floor. The edge closest
to the knockouts will be the edge towards the furnace.
See Fig. 4.
2. Place the desired vertical panel inside the bot-
tom tray and hold into place with one Tek screw in the
bottom middle hole. (solid panel shown) See Fig 4.
