Heater Expansion
It is a normal condition that during heat-up and cool-down a radiant
heater will expand and contract. Allowances for heater expansion
must be made in the gas connection and heater suspension. Im-
proper installation, alteration, or adjustment can result in property
damage, injury or death.
WARNING
Venting
Inadequate venting of a heater may result in asphyxiation, carbon
monoxide poisoning, injury or death. When used indoors, this heater
is indirectly vented from the space. Venting must be in accordance
with all local, state, provincial, and national codes (ANSI Z223.1/NFPA 54 in USA; B149.1 in
Canada) and as indicated in this manual. Refer to Section 13
Gas Connection
Improper installation, connection, or adjustment can result in property
damage, toxic gases, asphyxiation, injury or death. Use an approved
stainless steel flexible gas connector (field supplied) to connect to the
gas supply to the heater in accordance with all local, state, provincial, and national codes
(ANSI Z223.1/NFPA 54 in USA; B149.1 in Canada) and as indicated in this manual.
WARNING
WARNING
WARNING Start-up ‘Smoke’ & Discoloration Condition
During start-up, the heating of material coatings used in the production process of the heater
may create a small amount of smoke during the initial period of operation. This condition is
normal and temporary .
Ensure that there is sufficient ventilation to adequately clear any ‘smoke’ from the space.
Notify site management and safety personnel to ensure that alarm systems are not unduly activated.
Under certain conditions in some locations/environments, surface discoloration may occur on the
heater body due to heat, and products of combustion discharging from the heater. Some discolora-
tion is a normal occurrence and may be the result of the deposit of ambient air borne particulate or
gases within the space that have passed through combustion creating ‘smoke’. The combustion of
fuel gas in a clean environment will not cause any discoloration deposits. Surface discoloration does
not affect the operation or performance of the heater nor the manufacturer’s warranties.

Clearance to Combustibles
Location of flammable or explosive objects, liquids or vapors close to the heater may cause fire
or explosion and result in property damage, injury or death. Do not use, store or locate flamma-
ble or explosive objects, liquids or vapors in proximity of the heater.
The clearance to combustible material represents the minimum dis-
tance that must be maintained between the outer heater surface and a
nearby surface. The stated clearance to combustibles represents a
surface temperature of: Installed Indoor = 90F° (50C°) above room tem-
perature; Installed Outdoor = 117F° (65C°) above ambient temperature.
It is the installer’s responsibility to ensure that building materials with
a low heat tolerance which may degrade at lower temperatures are
protected to prevent degradation. Examples of low heat tolerance ma-
terials include vinyl siding, fabrics, some plastics, filmy materials, etc.
In locations used for the storage of combustible materials, signs must be posted to specify the
maximum permissible stacking height to maintain the required clearances from the heater to
the combustibles. For your convenience, a sign is supplied with this heater - see page 8 for de-
tails. Such signs must either be posted adjacent to the heater thermostats or in the absence of
such thermostats in a conspicuous location.
In addition to stored or stationary material, consideration must also be given to moveable ob-
jects such as cranes, vehicles, and overhead doors, and structural objects such as electrical
and gas lines, electrical fixtures, and sprinkler heads.
Heaters must be located an appropriate distance from sprinkler heads. This distance may be
greater than the certified clearance to combustibles. Check the temperature rating of the sprin-
kler heads and locate heaters at a safe distance - in some instances the sprinkler heads may
need to be replaced by higher temperature heads.
It is beyond the scope of these instructions to consider all conditions that may be encountered.
Consult local authorities such as the Fire Marshall, insurance carrier, or safety authorities if you
are uncertain as to the safety or applicability of the proposed installation.
Refer to Figure 1 and Table 1 NEXT PAGE for the certified clearances to combustibles
for the appropriate model input/size.

The clearance to combustible material represents the minimum distance that must be main-
tained between the outer heater surface and a nearby surface. The stated clearance to com-
bustibles represents a surface temperature of: Installed Indoor = 90F° (50C°) above room
temperature; Installed Outdoor = 117F° (65C°) above ambient temperature.
It is the installer’s responsibility to ensure that building materials with a low heat toler-
ance which may degrade at lower temperatures are protected to prevent degradation.
Examples of low heat tolerance materials include awnings, vinyl siding, fabrics, some plastics
and plastic coatings, filmy materials, etc.

from the heater to any vehicles parked below the heater.
Overhead heaters shall be installed at least 8 ft (2.4 m) above the floor.
4. INSTALLATIONS OTHER THAN SPACE HEATING
Use for process or other applications that are not space heating will void the C.S.A. certification
and product warranty. Process application requires field inspection and/or certification by local
authorities having jurisdiction. Process application design should be provided by local experi-
enced process design experts.
5. PRE INSTALLATION SURVEY
It is recommended that a full heating design including heat loss calculation be conducted on
the structure or area to be heated. Heater sizing and placement must consider available
mounting height, sources of greatest heat loss, and obstructions on the site. The certified clear-
ances to combustibles with respect to stored material, moveable objects (cranes, vehicles, lifts,
overhead doors, etc), structural components, and sprinkler system heads. Consideration must
also be given to ventilation fan placement (outdoor heaters do not require ventilation). Carefully
survey the area to be heated, and for best results place heaters in the coldest area(s) and at
sufficient spacing to provide uniform radiant heat coverage.
