ICP 8MPT Installation Insrtuctions page 6

The filters used to clean the circulating air during the °
construction process must be either changed or thor-
oughly cleaned prior to occupancy.
The furnace, ductwork and filters are cleaned as neces-
sary to remove drywall dust and construction debris from
all HVAC system components after construction is com-
)leted.
Dimensions and Clearances (*8MPT/*8MPV)
After construction is complete,verify proper furnace op-

InstallationPositions
This furnace can be installed in an upflow, horizontal (either teft or
right) or downflow airflow position. DO NOT install this furnace on
its back. For the upflow position, the return air ductwork can be at-
tached to either the left or right side panel and/or the bottom. For
horizontal and downflow positions, the return air ductwork must be
attached to the bottom. The return air ductwork must never be at-
tached to the back of the furnace.
Furnace Installation
Inspect the rating plate to be certain the model number begins with
"*8MPV" or "*8MPT'. This identifies the unit as a multi-position
furnace and can be installed in a Upflow, Horizontal Right, Hori-
zontal Left or Downflow position.
Upflow
No modifications are required for upflow installation. (See
