EDX Series 3.0 Installation •Design Considerations and Prechecks
3.0 Installation
Design Considerations and Prechecks
Placement of infrared heaters is influenced by many factors. Aside from safety factors, considerations such as
the number of heater or flue elbows that are allowed, maximum flue lengths, ducting of combustion air, and
combining exhaust flues are a few examples. All installation manuals along with national, state, provincial, and
local codes address these issues. It is critical that you read, understand, and follow all guidelines and
instructions.
To ensure a properly designed heating system, a layout should be developed for the correct placement of the
heating appliance, flues, and combustion air intake ducts. Inspect and evaluate the mounting conditions, flue
locations, gas supply, and wiring. Refer to Chart 3.1 on page 10 for the recommended mounting heights and
coverages for the model being installed.
NOTE: In outdoor applications, the effective infrared 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 28 for additional information.
WARNING
!
Improper installation, adjustment, alteration, service, or maintenance can cause
property damage, serious injury, or death.
Read and understand the installation, operating, and maintenance instructions
thoroughly before installing or servicing this equipment.
Only Gas Safe Registered Gas Engineers and service personnel may install or service
this equipment.
When designing an infrared radiant heating system, consider the following:
• Has the building’s heat loss been evaluated?
• Does the design meet the needs of the space?
• Have all clearances 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 environment harsh or contaminated (requiring outside air for combustion)?
• Are chemicals or vapor a concern (requiring outside air for combustion)?

10
EDX Series
3.0 Installation •Recommended Mounting Heights
NOTE: Factory recommended mounting heights are listed as a guideline. If infrared 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 the factory
recommended mounting heights. Clearances to combustibles must always be maintained.

Hanger Placement and Suspension
Suspension of the heater must conform to applicable codes referenced in the Safety section and these
instructions.
1Lay radiant tubing out in the following order. Position tubes in their approximate locations (see Figure
3.4).
• Primary combustion chamber.
• Radiant emitter tubes.
IMPORTANT! 43,9–60,0 kW 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.
2Mark locations for hanging points (see Figure 3.4).
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 71 cm.
• The space between the first two hangers placed on the first tube should be approximately 269 cm.
• The space between hangers thereafter, one per tube, should be approximately 295 cm.
WARNING
!
Improper suspension of the radiant tube heater may result in collapse and being crushed.
Always suspend from a permanent part of the building structure that can evenly support the
total force and weight of the heater.
Failure to maintain minimum clearances to combustibles may result in fire and/or explosion,
property damage, serious injury, or death. Always maintain minimum clearances.

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 3.8 •Tube Connections
A 180° U-Bend or 90° accessory fitting may be installed in the radiant tube heater system. Refer to page 18
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 46
cm.
• If operating the heater unvented, separate the intake air to the heater from its exhaust products a
minimum of 122 cm; further separation may be necessary. Outside 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 84 cm section of turbulator baffle. Refer to Baffle Assembly section.

Reflector Assembly
To install the reflectors:
1Attach reflector center supports onto radiant tubes.
2Slide each reflector section through the hangers and adjust the reflector tension spring into the V-groove
on the top of the reflector. The reflectors should overlap approximately 10 cm.
3To prevent the reflectors from shifting, secure the reflector sections together using sheet metal screws
except at the expansion joint (see page 22). NOTE: Installer to provide sheet metal screws.
4Attach reflector end caps, polished side inward, to each end of the reflector run.
Reflectors and reflector accessories direct infrared energy to the floor level. The reflector assembly
depends on the heater configuration, proximity to combustibles, and the space surrounding the heater.
Before you begin assembly, determine if the use of reflector accessories is necessary (see page 21).
