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.
Check to ensure that any alarm system is not unduly activated during start up.
CAUTION
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 TruTemp thermostat 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.

* SUGGESTED GUIDELINE MOUNTING HEIGHTS are typical to provide optimum comfort in
general space heating applications. Variance from these typical heights can occur in some
applications:
• Higher mounting height due to structure or application requirements
• For ‘area’ or ‘spot’ heat, or in areas with greater infiltration rates (near overhead doors,
etc) where more intense heat is needed to provide better comfort then lower mounting
heights are recommended (minimum 8 ft [2.4 m] mounting height)
• It is recommended that Protective Guard JS-0502-UR-GK be installed on any heater
mounted with less than 8 feet from floor to bottom of heater (See Accessories - Page 41)

.
1. Survey the available structural support, considering the system configuration and heat re-
quirements of the area to establish the optimum heater location.
2. Hardware with a minimum 100 lb. (30 kg) work load must be used at each heater suspen-
sion point. A #2 Lion Chain or equivalent is typically used to suspend the heater.
b) If rigid hardware such as 3/8” threaded rod is used for suspension, swing joints or other
means must be provided to allow for system expansion - approximately ½ inch
3. The heater must be supported at all four mounting tabs on the hangers that are located
72 inches (183 cm) apart .
4. Locating a heater directly under joists or beams, and/or installing supplemental support
such as angle iron can ensure the integrity of the installation.
5. The heater can be mounted with the tube/reflector in a horizontal position, or at 30° facing
toward the area to be heated. The burner must always be level (length and width) to ensure
proper operation of air switches and gas valve.
6. Install the structural fastening hardware and any suspension hardware (chain, etc) prior to
removing heater from the carton. Ensure that the support hardware system is firmly fas-
tened to a structural member(s) of sufficient strength and integrity to support the weight of
the heater.
7. The heater comes fully assembled from the factory. For locations where there is con-
strained access for installation, removal of the burner assembly may assist in the installa-
tion of the tube/reflector assembly. Disconnect the spark wire from the igniter and remove
the four nuts that fasten the burner to the tube flange. Re-install the burner after the tube
system is installed. If the tube/reflector system is to be oriented up to a 30° mounting angle
(see below), the burner must be adjusted to a horizontal position for operation.
: See Figure 6 next page
8. The tube/reflector system can be oriented on the short axis from horizontal to an angle up
to 30 degrees in either direction with the burner in the upper or lower position. The heater
must be level along its length, and the burner positioned level across its width.
9. If the tube/reflector assembly is to be suspended at an angle up to 30°, the burner mounting
flange has a slot pattern that allows adjustment (rotation) of the burner to a horizontal posi-
tion for proper operation - BURNER MUST BE HORIZONTAL ACROSS THE WIDTH (see
Figure 6 below).
• Install the tube/reflector system as above, with tube/reflector assembly angled up to 30°
• Loosen the 4 nuts (2 or 3 turns) until burner studs can rotate within the flange slots
• CAUTION: Use care to ensure that the gasket between burner and flange rotates with
the burner and is not damaged
• Rotate burner to level position across its width
• Tighten the 4 nuts to secure the burner in the horizontal position
10. For seismic and high wind restraint see Sections 10-A & 10-B, page 19.

Seismic restraint requirements vary greatly by geographic region or area. The infor-
mation below is a guideline only for suspension of the heater. Adhere to specific seismic re-
quirements and specifications of local engineering authority.
In areas prone to earthquake, or specified on a project, install lateral and longitudinal seismic
restraints as suggested in Figure 7. If the heater location can be impacted by wind (near over-
head doors, aircraft hangars, outdoors, etc) refer to High Wind Restraint section -below.
These guidelines indicate attachment of suspension and restraint hardware to the heater. The
attachment of suspension hardware to the structure will be as required by site structural condi-
tions, installation codes, and/or local engineering specifications. Other types or systems of re-
straint that are specified by local or national codes, or by project engineering design specifica-
tions may be required .
All required seismic mounting hardware is field supplied by the installer according to local
specifications.
-
In areas with wind conditions that can impact the heater (outdoor, aircraft hangers, etc): in ad-
dition to lateral and longitudinal restraint the heater should be restrained from vertical move-
ment (lift).
Suspend the heater us-
ing 3/8” threaded rod
with 3” adjustment turn-
buckle at each hanger
location to restrain up-
and-down movement.
Install angled chains for
lateral and longitudinal
restraint.
Use Rod for Main Suspension

poisoning, injury or death. This heater must be connected to a vent to remove
products of combustion from the space. Seal all vent connections with high
temperature sealant. Venting must be in accordance with all local, state, provin-
cial, and national codes (ANSI Z223.1/NFPA 54 in USA) and as indicated below
in this manual.
-
It is the sole responsibility of the installer to adhere to all current local codes and/or ANSI
Z223.1 latest editions for all venting requirements, and practices.
It is a normal condition that during heat-up and cool-down a tube heater will expand and con-
tract. Allowances for heater expansion must be made in the venting. Improper installation can
result in property damage, injury or death.
• This heater has a positive vent pressure
• A vent termination cap is recommended for use with horizontal side wall vent
• All vent pipe and adapters will be supplied locally by others

• A minimum 12 inch (30 cm) length of minimum 26 gauge single walled 4” (10 cm) diameter
“C” vent pipe is to be installed on the swaged end of the tube before any vent elbow is fitted.
• Vent connections
must be secured with three (3) #8 sheet metal screws uniformly spaced around the circum-
ference of the vent pipe.
• When the vent pipe passes through a cold or unheated area where the ambient temperature
is likely to produce condensation of the flue gases, the vent pipe will be insulated with a suit-
able material as approved and specified by the insulation manufacturer to withstand tem-
perature up to 460°F (238°C).
• The vent system must be adequately supported to prevent sagging.
