HORIZONTAL UNITS
1. Position the unit to minimize long runs of duct or runs of
duct with many turns and elbows.
2. Unit can be mounted left or right side airflow configuration.
3. Position the unit on adequate supports or by using support
brackets (see Figure 8) and connect supply plenum.
4. If summer air conditioning is desired, position the indoor coil on
the supply air side of the unit. Insure that no air can bypass
this coil.
5. Secure the four angle brackets (shipped with (-)801P units) to
the return air opening. See Figure 9. Connect the return air
ducting to the return air opening at the top of the unit. Make the
connection air tight to prevent entraining combustion gases
from an adjacent fuel-burning appliance.
NOTE: Do not block furnace access with support rods. Main-
tain clearances recommended in Figure 8. Allow enough
space for proper service maintenance or replacement of the
heat exchanger and blower assembly.
