INSTALLING YOUR FURNACE
FIGURE 2 - MINIMUM CLEARANCES
11. Be sure to provide adequate clearance and service
access. The front of the furnace must face the
open room.
12. Choose a location for the thermostat (optional) about
5-feet above the floor on an inside wall. The
thermostat wire supplied with your furnace is 20-feet
long, which should be enough to run up through the
attic of a single-story home, so the thermostat can be a
maximum of 16-feet from the furnace measure in a
straight line, or about 8-feet from the furnace if the wire
is run under the floor. Use heavier wire size if more than
20-feet of wire is required. The thermostat should be
sensing average room temperature.
AVOID THE FOLLOWING:
HOT SPOTS
COLDSPOTS:
Concealed pipes or ducts

13. After picking a location that meets the requirements,
inspect the wall, floor and outside areas. Make sure
there are no pipes, wiring, or anything else that would
interfere with furnace, vent, or thermostat installation.
If required, move them or pick a new location.
RECESSED INSTALLATION CLEARANCE NOTE:
A
portion of the furnace that is recessed into a wall up to
10” maximum recess may have (0) zero inch clearance to
combustibles.
