FURNACE LOCATION

This furnace is design certified for installation in an alcove,
closet, basement, attic, garage or utility room. The 50-125
MBH models may be installed in an upflow, downflow or hori-
zontal position on either side. The 150 MBH model may be
installed in an upflow or a horizontal left or right position. It is
certified only for use in a home constructed on-site or a man-
ufactured home completed at the final site. This furnace is not
design certified to be installed outdoors, in a mobile home,
trailer or recreational vehicle.
The furnace should be located as close to the chimney or
vent as possible and as close to the center of the warm air
distribution system as possible.
When the furnace is installed in a residential garage it must
be located and installed such that it will be protected from
damage by vehicles. The furnace must be installed so that
the burners are a minimum of 18" above the floor.

When the furnace is installed in the horizontal position, line
contact is permissible. The line formed by the intersection of
the top and sides of the furnace may be in contact with com-
bustible material.
Do not install the furnace on its back. Doing so
could cause a fire, resulting in damage, injury or
death.
Provide sufficient space around and in front of the furnace for
service and cleaning. Allow a minimum of 24 inches from the
front of the furnace for service clearance. If the furnace is to
be installed in a close clearance closet, the door should be of
adequate size to allow for removal of the furnace should it
become necessary.
Failure to maintain proper clearances to combus-
tible materials can cause a fire, which could result
in damage, death or personal injury.
NOTE:
This furnace must be installed so the electrical com-
ponents are protected from water.
