Installation/Service Instruction
Receiving Equipment
On receipt of equipment it is suggested that a visual
inspection be made for external damage to the carton. If
the carton is damaged, a note should be made on the Bill
of Lading when signing for the equipment. Remove the
heater from the carton
. If there is damage, report the
damage to the carrier immediately
.
INSTALLATION INSTRUCTIONS
Important Notice
These instructions are intended for qualified personnel,
specifically trained and experienced in the installation of
this type of equipment and related system components.
Some states or provinces require installation and service
personnel to be licensed. If your state or province is
such, be sure your contractor bears the appropriate
license. Persons not qualified shall not attempt to fix this
equipment nor attempt repairs.
WARNING
Asphyxia, Explosion or Fire
Improper installation, adjustment,
alteration, service or maintenance may
create a hazard resulting in asphyxiation,
explosion or fire, or damage to the
equipment.
Code Requirements
Installation must be in accordance with local codes, or in
the absence of local codes, with the latest edition of the
National Fuel Gas Code, ANSI Z224 and National
Electrical Code ANSI/NFPA 70, and for Canada, the
latest edition of CAN/CGA-B149.1 and B149.2 and
Canadian Electrical Code, CSA C22.1 Part 1 and Part 2.
•
Heaters to be installed in Aircraft hangars must be
installed in accordance with American National
Standards for Aircraft Hangars, ANSI/NFPA
No. 409.
•
Heaters to be installed in Public Garages must be
installed in accordance with NFPA No. 88A,
Standards for Parking Structures.
•
Heaters must be installed so that minimum
clearances marked on the heaters will be
maintained from vehicles parked below the heater.
•
Each heater must be electrically grounded in
accordance with the National Electrical Code,
ANSI/NFPA 70, when an external electrical source
is utilized. In Canada, the CSA Canadian Electrical
Code, C22.1 Part 1 applies.
Gas Supply
The gas inlet supply pressure and manifold pressure required for
each heater are listed below. For gas supply line pressures in
excess of ½ psig, consult with your gas service provider or the
factory.

It is critical that the gas piping system be adequately sized
for all the gas appliances it serves.
Clearances
Each heater must be installed such that the following
“Minimum Clearance to Combustible Materials’ are maintained.
Combustible materials include wood, compressed paper, plant
fibers, plastic, Plexiglas or other materials capable of being
ignited and burned. Such materials shall be considered
combustible even though flame-proofed, fire retardant treated or
plastered. Additional clearance may be required for glass,
painted surfaces, vinyl siding or other materials which may be
damaged by radiant or convection heat.
Adequate space around each heater is required even when the
materials surrounding the heater are non- combustible to provide
adequate combustion air and ventilation of exhaust gases.
Heaters should never be located in a ceiling recess or soffit.
The stated clearance to combustible materials represents a
surface temperature of 90ºF (32ºC) above room temperature.
Building materials with a low heat tolerance (such as plastic, vinyl
siding, canvas, tri-ply, etc.) may be subject to degradation at
lower temperatures. It is the installer’s responsibility to assure
that adjacent materials are not subject to degradation.
In locations used for storage of combustible materials, signs
shall be posted to specify the maximum permissible stacking
height to maintain required clearances from the heater to
combustible materials.
OPTIONAL MOUNTING KIT (#12006):
Optional Mounting Kit is
included in some packages. Whether the mounting kit is used or
not, minimum clearance from combustibles must be observed as
follows:
WARNING:
The clearances shown below are also applicable to
vehicles parked below heaters.
