NOTE - For installation on combustible floors, the furnace
shall not be installed directly on carpeting, tile, or other
combustible material other than wood flooring.
Accessibility and service clearances must take preceĆ
dence over fire protection clearances.
For installation in a residential garage, the furnace must
be installed so that the burner(s) and the ignition source
are located no less than 18 inches (457 mm) above the

physical damage by vehicles. When a furnace is installed
in a public garage, hangar, or other building that has a
hazardous atmosphere, the furnace must be installed acĆ
cording to recommended good practice requirements
and current National Fuel Gas Code or CAN/CGA B149.1
and B149.2 standards.
When the furnace is used with cooling units, it shall be
installed in parallel with, or on the upstream side of, cool-
ing units to avoid condensation in the heating compartĆ
ment. With a parallel flow arrangement, a damper (or othĆ
er means to control the flow of air) must adequately
prevent chilled air from entering the furnace. If the dampĆ
er is manually operated, it must be equipped to prevent
operation of either the heating or the cooling unit, unless it
is in the full HEAT" or COOL" setting.
When installed, the furnace must be electrically grounded
according to local codes. In addition, in the United States,
installation must conform with the current National ElecĆ

Field wiring connections must meet or exceed specificaĆ
tions of type T wire and withstand a maximum temperaĆ
ture rise of 180°F (82°C).
G32V unit must be installed so that electrical components
are protected from water.
When the furnace is installed so that supply ducts carry
air circulated by the furnace to areas outside of the space
containing the furnace, return air shall be handled by a
duct(s) sealed to the furnace casing and terminating outĆ
side space containing furnace.
