2. Install the louver panels in the desired location(s) with the self-tapping screws provided. Holes
are pre-drilled in the furnace cabinet to accommodate installation of the panels.
3. Adjust the louvers for the desired air flow direction.
ATTENTION: DO NOT restrict the flow of the hot air from the furnace by closing the louvers,
or the furnace will not operate properly.
4. Install the blank covers over the remaining air discharge opening(s) on the furnace cabinet.
• When determining the
placement of the air discharge
louvers, you also need to consider
the required clearances from
combustibles as stated in

supplied with (2) louver sections
which may be installed together
on one side or the bottom OR the
louvers may be split for partial air
discharge on each side and/or
bottom. If a side contains only
