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
according to these instructions.
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
representative or the factory.
Gas Inlet Pressure Nat Gas Propane
Maximum Pressure ½ psig ½ psig
Minimum Pressure 6” W.C. 11” W.C.
Manifold Pressure 5” W.C. 10” W.C.
It is important 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, and 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 available from your heater supplier. 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.
