CLEARANCE TO COMBUSTIBLE MATERIALS in inches (mm)
TOP FRONT BACK FLOOR SIDES ACCESS SIDE
6(152) 6(152) 6(152) 3(76) 6(152) 18(457)
All units installed on the floor have a minimum clearance of 3" (76mm) provided by the base frame
of each individual unit.
For service it is advisable to maintain a minimum 24' clearance on the side opposite the controls
side. If this unit is to be operated within a confined space or within a building of unusually tight
construction, air for combustion and ventilation must be obtained from outdoors or other spaces
freely communicating with the outdoors. Refer to current United States and Canadian Fuel Codes.
Ducts connected to the furnace shall have removable access panels on both the upstream and
downstream sides of the furnace. These openings shall be accessible when the furnace is installed
and shall be sized to allow for the observation of smoke or reflected light inside the casing to
indicate the presence of leaks in the heat exchanger. The covers for the openings shall be attached
in such manner as to prevent leaks.
WARNINGS
Ø The furnace must not be operated in the presence of hazardous atmospheres
containing flammable vapours or combustible dust, chlorinated vapours or
halogenated hydrocarbons, or in applications with airborne substances
containing silicone. When such vapours mix with products of combustion,
highly corrosive compounds result, which will result in the premature failure
of the heat exchanger and other components. In such an event the warranty is
void.
Ø The duct furnace is not certified or suitable for use in drying process
applications. Use in such application voids any warranty and as the
manufacturer disclaims any responsibility for the duct furnace and/or
application.
Ø The use and storage of gasoline or other flammable liquids in the vicinity of
the appliance is hazardous.
