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
surface’s temperature does not exceed 90 degrees above
the ambient temperature.
For specific dimensions, refer to the submittal drawing
for the specific fan type.
Installation of the heater (1) in airplane
hangars must be done in accordance with
the Standard for Aircraft Hangars, ANSI/NFPA
409, and (2) public garages must be done in
accordance with the Standard for Parking
Structures, ANSI/NFPA 88A, or the Standard
for Repair Garages, ANSI/NFPA 88B, and with
CAN/CSA B149.1 Natural Cas and Propane
Installation Codes.
NOTICE! Adequate building relief shall be provided
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
interlocking a powered exhaust system; or by a
combination of these methods.
NOTICE! All indoor and outdoor units require
that the air to the heater is ducted directly from
the outdoors. Recirculation of room air is not
permitted.
NOTICE! The heater inlet shall be located in
accordance 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, consult
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
Rotating Parts & Electrical Shock Hazard
Improper installation and handling can
result in electric shock, possible injury due
to coming in contact with moving parts, as
well as other potential hazards.
Disconnect electric power before working
on unit.
Follow proper lockout / tagout procedures to
ensure the unit cannot be energized while
being installed or serviced.
A disconnect switch should be placed
near the fan in order that the power can
be swiftly cut off, in case of an emergency
and in order that maintenance personnel
are provided complete control of the power
source.
Verify that the power source is compatible
with the equipment. Grounding for the motor
is required. All field-installed wiring must
be completed by qualified personnel. All
field installed wiring must comply with local
electrical and safety codes, National Electric
Code(NEC), the National Fire Protection
Agency (NFPA 70), and Canadian Electric
Code (CEC) – when in Canada.
Do not allow the power cable to kink
or come in contact with oil, grease, hot
surfaces, or chemicals. Replace cord
immediately if damaged.
Never open blower access doors while the
fan is running.
Failure to follow these instructions could
result in death, serious injury or property
damage.
