3.0 Installation
Placement of infra-red tube heaters is influenced
by many factors. Aside from safety factors,
considerations such as the number of elbows that
are allowed, maximum flue lengths and ducting of
combustion air are a few examples. It is critical that
all guidelines and instuctions are followed.
3.1 Design Considerations and Prechecks
NOTE: The effective infra-red surface temperature
of a person or object may be diminished with wind
above 8 km/h. The use of adequate wind barrier(s)
may be required.
NOTE: When heated, materials high in
hydrocarbons (solvents, paint thinner, mineral
spirits, formaldehydes, etc.) can evaporate. This
may result in odors or fumes being emitted into the
environment. To correct this problem, clean the
area and/or introduce additional ventilation.
Heaters installed and serviced in accordance with
the installation manual do not emit odors into the
environment. See notice on page 30 for additional
information.
• Has the building’s heat loss been evaluated?
• Does the design meet the needs of the space?
• Have all clearance to combustible situations been
observed?
• Have recommended mounting heights been
observed?
• Is the supply (burner) end of the heater located
where more heat is required?
• Is it best to offset the heaters and/or rotate the
reflectors towards the heat zone?
• Are protective guards, side shields, ‘U’ or ‘L’
reflector covers needed?
• Does the heater require outside fresh air for
combustion?
• Is the enviroment harsh or contaminated
(requiring outside air for combustion)?
• Are chemicals or vapor a concern (requiring
outside air for combustion)?
To ensure a properly designed heating system, a
heating layout should be developed for the correct
placement of the burner control box, radiant
tubing, flueing and combustion air intake ducts.
Inspect and evaluate the mounting conditions, flue
locations, gas supply and electrical wiring. Refer to
the chart below for the recommended distances for
the model being installed.
When designing an infra-red radiant heating system, consider the following:

3.2 Recommended Mounting Heights (Industrial/Commerical Applications)
NOTE:
Factory recommended mounting heights are listed as a guideline. If infra-red heaters are mounted too low or too
high, they may result in heat discomfort or lack of heat. It is generally recommended to observe the recommended
mounting heights to optimize comfort conditions. However, certain applications such as spot heating, freeze
protection, outdoor patio heating or very high ceilings may result in the heaters being mounted outside of of the factory
recommended mounting heights. Clearances to combustibles must always be maintained.

3.3 Hanger Placement and Suspension
WARNING
Improper suspension of the heater may result in collapse and being crushed. Always
suspend the appliance from a permanent part of the building structure that can
support the total weight and force of the heater.
WARNING
Failure to maintain the published clearance to combustibles may result in fire and/or
explosion, property damage, serious injury or death. Always maintain clearances and
post signs where needed.
Suspension of the heater must conform to applicable codes referenced in the Safety section and these
instructions.
1Remove unit from packaging and discard all transit protection materials.
NOTE: All packaging material are external of the burner and tubular exchangers.
2Lay radiant tubing out in the following order. Position tubes in their approximate locations. Figure 3.7.
• Primary combustion chamber.
• Radiant emitter tubes.
IMPORTANT! 152-163 MJ/h models must use the titanium alloy treated combustion chamber
as the first tube connected to the burner control box. The combustion chamber has an orange
identification sticker located on the swaged end of the tube.
3Mark locations for hanging points. Figure 3.7.
NOTE: If the available hanging points do not allow for the recommended spacing (or if an
alternative hanging method is utilized) then additional hangers may be necessary.
• The spacing between the burner control box mounting brackets and the first hanger should be
approximately 711mm.
• The space between the first two hangers placed on the first tube should be approximately
2692mm.
• The space between hangers thereafter, one per tube, should be approximately 2946mm.

Suspension of the heater must conform to applicable codes referenced in the Safety section and these
instructions.
3Prepare the mounting surface. If necessary, weld blocks, drill holes, etc. Figure 3.8.
NOTE: The burner control box and radiant tubes should be in straight alignment and level.
4Fasten beam clamp, screw hook, or other type of suspension anchor to hanging point.
5Attach and close S-hook and double-loop chain to anchor. Check that it is securely attached.
NOTE: Threaded rod and turnbuckles may be used.
6Attach hangers to chains. Adjust chain lengths until radiant tubing is level and equal weight distribution
is achieved. NOTE: Chains must be straight up and down. Do not install chains at an angle as this can
result in tube warpage or separation.

U-Tubes can be mounted at a
15, 30 or 45 degree angle with two
suspension points, using two Brass Knuckle
(P/N: BK) fittings, double-loop chains and S-hooks.
U-Tubes can be mounted from a single suspension
point using a Single Mounting Bracket (P/N: SMB)
with five S-hooks and double-loop chains.

3Slip-fit the radiant tube sections together until tightly connected (install swaged end of each tube towards
exhaust end). NOTE: If it is difficult to mate the tubes, they may be installed incorrectly.
4Center tube clamps over the seams where two radiant tube sections connect. If necessary, rotate tube
clamps so they will not interfere with the reflector end caps during expansion and contraction of the
heater while operating.
5Tighten tube clamp bolts to secure. When proper compression is obtained (30-44 Nm), the tube seam
will create a visible mark on the tube clamp. NOTE: Excessive torque may damage the tube clamp.
6Determine the location of the burner control box and note the placement of the mounting chains.
Figure 3.13 •Tube Connections
Optional U-Bend or Elbow Accessory Configurations
A 180 degree U-bend or 90 degree accessory fitting may be installed in the radiant tube heater system.
Refer to page 19 for minimum distance requirements from the burner control box.
When installing a U-bend or Elbow Accessory Fitting:
• The top clearance of an uncovered (no reflector) U-bend or elbow accessory fitting to combustibles is
458mm.
• If operating the heater un-vented, separate the intake air to the heater from its exhaust products a
minimum of 1220mm; further separation may be necessary. Combustion air may also be supplied.
• A maximum of one 180° U-bend or two 90° elbows can be installed on a heater.
• Omit one 840mm section of turbulator baffle. Refer to Baffle Assembly section.
