Clearance to Combustible / Service Clearances

The minimum distance required between the heater and

adjacent combustible surfaces is 42 inches (1066.8 mm),

on the controls side of the unit, to ensure the adjacent sur-

face's temperature does not exceed 90 degrees above the

ambient temperature.

NOTICE! Adequate building relief shall be provid-

ed so as to not over pressurize the building when

the heating system is operating at its rated capacity.

It should be noted that this can be accomplished by

taking into account, through standard engineering

methods, the structure's designed infiltration rate; by

providing properly sized relief openings; or by inter-

locking a powered exhaust system; or by a combina-

tion of these methods.

NOTICE! All indoor and outdoor units require that

the air to the heater is ducted directly from the out-

doors. Recirculation of room air is not permitted.

NOTICE! The heater inlet shall be located in accor-

dance with the applicable building code provisions for

ventilation air.

NOTICE! Field constructed intake accessories

should be properly designed to minimize the entry of

snow and rain.

NOTICE! If in doubt regarding the application, con-

sult the heater manufacturer.

Indoor Hanging Arrangement

1. Install threaded hangers from ceiling supports. When

locating hangers, allow enough room to open access

panel(s). Two nuts must be used on the end of each

threaded hanger. Ceiling supports are not supplied.

2. Using sheet metal screws, attach the weatherhood/

thru-wall / filter section to the damper / burner sec-

tion. The flange on the weatherhood / thru-wall / filter

section should overlap the flange on the damper /

burner section.

3. Raise the unit into place

4. Using two nuts per hanger, fasten the unit supports

to the hangers under the unit. Appropriate unit sup-

ports, such as the optional hanging bracket kit or

c-channel and angle iron (not included) should be

used.

5. Attach ductwork to unit using self-tapping screws

NOTICE! In order to prevent the unit from swinging

and to provide a safe environment for service and

maintenance, additional measures may be needed to

secure the unit.
