Heater Expansion
It is a normal condition that during heat-up and cool-down a tube
heater will expand and contract. Allowances for heater expansion
must be made in the gas connection, venting and combustion air
ducting. Improper installation, alteration, or adjustment can result in
property damage, injury or death. Refer to Section 13
WARNING
Venting
Inadequate venting of a heater may result in asphyxiation, carbon
monoxide poisoning, injury or death. This heater may be directly or
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 Sections 11 & 12
Gas Connection
Improper installation, connection, or adjustment can result in property
damage, toxic gases, asphyxiation, injury or death. Using an ap-
proved flexible gas connector in the USA or Type 1 hose connector in
Canada, the gas supply to the heater must be connected and tested
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
WARNING
WARNING Start-Up ‘SMOKE’ Condition
During start up, the heating of material coatings used in the production process of tubes and
reflectors will create 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 and safety personnel to ensure that alarm systems are not unduly activated.
IMPORTANT THERMOSTAT SETTING FOR COMFORT
Infrared radiant (IR) heating system provide comfort with the effect of radiant heat and ambient
air heat.
If your IR system is controlled with a thermostat (TruTemp or ThermoControl Plus) that senses
radiant heat, then set the thermostat to the desired comfort temperature (ie: 65°; 68°; 20°C).
If your IR system is controlled with a standard 24V or 120V thermostat that senses only air tem-
perature, then start with a thermostat setting that is 5° to 7°F (3° to 5°C) lower than the desired
comfort temperature. Some trial and error setting may be required to ‘fine tune’ the comfort tem-
perature that best suits your site and provides most economical operation.

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 90F° (50C°) above room temperature. It is the
installer’s responsibility to ensure that building materials with a low
heat tolerance which may degrade at lower temperatures are pro-
tected to prevent degradation. Examples of low heat tolerance mate-
rials 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. 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 objects such as cranes, vehicles, and
overhead doors, and structural objects such as sprinkler heads, electrical and gas lines, and
electrical fixtures.
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 for the certified clearances to combustibles for the appro-
priate model input/size.
WARNING
WARNING Tube “GLOW”
It is a normal condition that the combustion tube (1st tube) can appear to “glow red”. For inputs
up to 150,000 Btuh, the top surface of the tube can appear red where heat is trapped between
the reflector and the tube. The stainless steel tube used for inputs 175,000 and greater can ap-
pear to entirely glow red. The tube material is designed into the heater because it can with-
stand the high temperature of combustion, and the “red glow” is a normal occurrence.

VENT END CLEARANCE: Clearances from the vent pipe are determined by local or national
installation codes, but must not be less than 6 inches (15 cm). For ‘unvented’ installation, a
minimum distance of 24 inches (61 cm) is required from the end of heater to a combustible
surface.
In locations used for the storage of combustible materials: Signs
must be posted specifying the maximum permissible stacking height to
maintain the required clearances from the heater to the combustibles.
The signs must be posted either adjacent to the IR heating system thermostats or in the ab-
sence of such thermostats, in a conspicuous place.
For your convenience a “peel and stick” sign
is provided with this heater. Use a permanent
marker to record the required dimensions on
the sign.
To calculate the value ‘H’: (H= T- C)
 Measure the on site distance between bottom of
the heater and the floor = ‘T’ inches (cm).
 Refer to Table 1 to get the value ‘C’ that corre-
sponds to the model you are installing
 Subtract the clearance below the heater ‘C’ from
‘T’ to get value ‘H’.
 Enter this value ‘H’ on the sign.
Refer to the information for the heater model
being installed in Figure 1 and Table 1 to get
the values for dimensions ‘S’, ‘F’ and ‘B’.

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 the certified clearances to combustibles
with respect to stored material, moveable objects (cranes, vehicles, lifts, overhead doors, etc),
sprinkler system heads, and other obstructions on the site. Consideration must also be given to
vent / duct placement and the allowable combined lengths of vent and duct. Carefully survey
the area to be heated, and for best results place burner and combustion chamber in the coldest
area(s) .
Installation must conform with all local, state, provincial and national code requirements includ-
ing the current latest edition ANSI Z223.1 (NFPA 54) in the U.S.A. and B149.1 installation
code in Canada, for gas burning appliances and equipment. The latest edition Electrical Code
ANSI/NFPA N0 70 in the U.S.A. and PART 1 CSA C22.1 in Canada must also be observed.
The heating system must have gas piping of the correct diameter, length, and arrangement to
function properly. For this reason, a layout drawing is necessary.
