Clearances to Combustibles
Combustible items: Moving Objects:
• Wood • Paint • Overhead doors
• Paper • Parked vehicles • Vehicle lifts
• Fabric • Gasoline • Cranes
• Chemicals • Storage racks • Hoists
• Plastics
A critical safety factor to consider before installation is the clearances to combustibles. Clearance to
combustibles is dened as the minimum distance you must have between the tube surface, or reector,
and the combustible item . Considerations must also be made for moving objects around the tube heater.
The following is a partial list of items to maintain clearances from:
• Vehicle parking areas
• Vehicles with lifts or cranes
• Storage areas with stacked materials
• Lights
• Sprinkler heads
• Overhead doors and tracks
• Dirty, contaminated environment
• Gas and electrical lines
• Combustible and explosive materials
• Chemical storage areas
• Areas of high chemical fume concentrations
• Provisions for accessibility to the heater
• Adequate clearances around air openings
• Combustion and ventilating air supply
Hazards:
For maximum safety the building must be evaluated for hazards before installing the heating system.
Examples of hazards include, but are not limited to:
If you are unsure of the potential hazards, consult your local re marshal, re insurance carrier or other
qualied authorities on the installation of gas red tube heaters for approval of the proposed installation.
Safety Signs and Labels
It is important to provide warnings to alert individuals to potential hazards and safety actions. ANSI Z83.20
and CSA 2.34 require you to post a sign “specifying the maximum permissible stacking height to maintain
the required clearances from the heater to the combustibles” near the heaters thermostat or, in absence of
such thermostats, in a conspicuous location. Contact Brant Radiant Heaters Ltd. or an authorized dealer
for Clearance Safety Limit Signs(P/N: BR-SIGN).
Safety warning labels must be maintained on the tube heater. Illustrations of the safety labels, and their
locations, are pictured in the Series Manual. 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 combustibles. Signs must either be posted adjacent to the heater
thermostats or, in the absence of such thermostats, in a conspicuous location.
WARNING
!
Placement of explosive objects, ammable objects, liquids and vapours close to the
heater may result in explosion, re, property damage, serious injury or death. Do not
store or use explosive objects, liquids and vapour in the vicinity of the heater.

When installing the tube heating system, the minimum clearances to combustibles for your model tube
heater and system conguration must be maintained. Refer to Chart 2.4 below to determine the required
distances for your model.
The stated clearances to combustibles represents a surface temperature of 90°F (50°C) above room temperature.
Building materials with a low heat tolerance (such as plastics, vinyl siding, canvas, tri-ply, etc.) may be subject to
degradation at lower temperatures. It is the installer’s responsibility to ensure that adjacent materials are protected
from degradation.

3.0 Installation
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 trained, qualied gas installation and service personnel may install or service
this equipment.
Design Considerations and Prechecks
Placement of infrared heaters is inuenced by many factors. Aside from safety factors, considerations
such as the number of heater or vent elbows that are allowed, maximum vent lengths, ducting of
combustion air and combining exhaust vents are a few examples. This installation manual, along with
national, 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 burner control box, tubes, vents and combustion air intake ducts. Inspect and evaluate the mounting
conditions, vent locations, gas supply and wiring.
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 recommended mounting heights been observed?
• Have all clearance to combustibles situations 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 reectors towards the heat zone?
• Are extra guards, side shields, ‘U’ or ‘L’ reector covers required?
• Does the heater require outside fresh air for combustion?
• Is the environment harsh or contaminated (requiring outside air for combustion)?
• Are chemicals or vapours a concern (requiring outside air for combustion or additional ventilation)?
IMPORTANT: Fire sprinkler heads must be located at an appropriate distance from the heater to avoid an
inadvertent discharge. This distance may exceed the published clearances to combustibles. Certain
applications may require the use of high temperature sprinkler heads or the relocation of the heaters.
CAUTION
!
Fire sprinkler systems containing propylene glycol, antifreeze or other potentially ammable
substances shall not be used in conjunction with this heater without careful consideration for and
avoidance of inadvertent discharge hazards. For further information consult NFPA 13. Always
observe applicable provinces and local codes.

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. The heaters themselves, when installed
and serviced in accordance with the installation manual, do not emit foul odors into the environment.

Factory recommended mounting heights are listed as a guideline. If infrared heaters are mounted too low
or too high, they may result in discomfort or lack of heat. Brant Radiant Heaters Ltd. generally
recommends observing 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.

• 10 ft. primary combustion chamber.
• Radiant emitter tubes.
Important! 150,000-200,000 BTU/h models must use the 10 ft. titanium alloy treated combustion
chamber as the rst tube downstream of the burner control box. The combustion chamber has a
yellow identication label located on the swaged end of the tube (remove label prior to starting up
heater).
2
Mark locations for hanging points.
NOTE: If the available hanging points do not allow for the recommended spacing then additional
hangers (P/N: TP-19B) may be necessary.
• The spacing between the burner control box mounting brackets and the rst hanger should be
approximately 2’-4”(0.7 m).
• The space between the rst two hangers placed on the rst tube, should be approximately
8’-10”(2.7 m).
• The space between hangers thereafter, one per tube, should be approximately 9’-8”(3 m).
Hanger Placement and Suspension
Improper suspension of the 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 re and/or
explosion, property damage, serious injury or death. Always maintain minimum
clearances and post Clearance Safety Limit signs (P/N: BR-SIGN) where needed.

Optional Elbow or U-Bend Accessory Conguration
A 90 degree elbow or 180 degree U-bend accessory tting may be installed in the radiant tube heating
system. Refer to Chart 3.3 on page 21 for minimum distance requirements from the burner control box.
When installing an Elbow or U-Bend Accessory Fitting:
• The top clearance of an uncovered (no reector) elbow or U-bend accessory tting to combustibles
is 18 in (0.4 m).
• If operating the heater unvented, separate the intake air to the heater from its exhaust products a
minimum of 4 ft., further separation may be necessary. Combustion air may also be supplied.
• A maximum of two 90° elbows or one 180° U-bend can be installed on a heater.
• Omit one 36 in. section of turbulator bafe. Refer to Bafe Assembly section on page 25.
3Slip-t the radiant tube sections together until tightly connected (install the swaged end of each tube
towards exhaust end). NOTE: If it is difcult to mate the tubes, they may be installed incorrectly.
4Center tube clamps over the seam where two radiant tube sections connect. If necessary, rotate tube
clamps so they will not interfere with the reector end caps during expansion and contraction of
the heater.
Tighten tube clamp bolts to secure. When proper compression is obtained (40-60 ft-lbs. torque) 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.
