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.
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.
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 test-
ed 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.
-‘’
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.
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 or ThermoControl Plus controller that senses radi-
ant heat, then set the control 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 the site and provides most economical operation.
Unoccupied (night) set-back of 9°F (5°C) is recommended. Do not turn the system ‘Off’.

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.
’
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.

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.

* GUIDELINE MOUNTING HEIGHTS are typical to provide optimum comfort in general space
heating applications. Variance to these typical heights can occur in some applications:
• Higher mounting heights due to structure or application requirements
• Lower mounting heights for area or ‘spot’ heat, or in areas with greater infiltration losses
(near overhead doors, etc)
: Single or multiple heater placement must be such that continu-
ous operation of heater(s) will not cause combustible material or materials in
storage to reach a temperature in excess of the ambient temperature in the

Inadequate or improper suspension of the tube heater can result in collapse of
the system, property damage, and personal injury or death.
It is the installer’s responsibility to ensure that the hardware and structural sup-
ports from which the heater is suspended are sound and of adequate strength
to support the weight and expansion forces of the heater.
Consider that the heater will expand in length as much as 1/2 inch (12.5 mm) or more for every
10 ft (3 m) of system length – typically the greater the firing rate, the greater the expansion.
1) Survey the available structural supports, considering the system configuration and heat re-
quirements of the area to establish the optimum heater location.
a) Locating a heater directly under joists or beams, or installing supplemental steel support
rail or angle iron can substantially reduce labor and materials
2) Hardware with a minimum 60 lb. (30 kg) work load must be used at each heater suspension
point. A #8 Jack Chain or equivalent is typically used for suspending the heater.
a) Connect to the structure using typical hardware as illustrated in FIGURE 6 (below) or by
other mechanically sound means
b) If rigid devices such as 3/8” threaded rods are used for suspension, swing joints or other
means must be provided to allow for system expansion - approximately ½ inch to 1 inch
for every 10 ft (1 cm to 2.5 cm for every 3 m) of system length.
3) Tube system hangers must be located:
i: Straight in line
ii: At a common height (level)
NOTE: It is important that the
tubes in the system are in-
stalled in alignment horizontal-
ly (level) and vertically (in line)
– this will ensure system integ-

• Also lay the vent end tube on to the first two hangers - check tubes for turbulator la-
bel to ensure the correct tube is located at the vent end
NOTE: INSTALL THE FIRST AND SECOND TUBES (FROM BURNER) WITH THE WELDED SEAM
ALONG THE TUBE LENGTH FACING DOWNWARD
3) Fasten flanged tube to hangers with ‘U’ bolts:
• All tubes on the burner-side of the heater are bolted to the hangers with ‘U’ bolts
• Tubes on vent-side simply rest in the hanger notch and do not fasten to the hanger.
4) Install Flame Rectifier (EXCEPT input 80/60); install igniter - See Figure 8A previous page.
5) Bolt burner to flange on first tube section - See Figure 8B previous page.
6) Slide a Torctite tube coupler over the swaged end of the first tube, then join the second tube
over the swage in the first tube -
7) Slide the Torctite coupler into position across the center of the tube joint - SEE FIGURE 9
: TOURQUE THE COUPLER BOLTS TO 40 ft-lbs
8) Subsequent lengths of tube can then be installed on both sides of the hangers by joining
them together swaged portion inside the next tube and locking the joints using the Torctite
coupler. SEE FIGURE 9.
9) Install Turn Box: See Fig 12B
• The Turn Box has “long” and “short” tube legs
• The ‘long’ leg attaches to the burner-run tubes
• The ‘short’ leg attaches to the vent-run tube side - tubes end short of burner for con-
nection of vent pipe

---‘’-: After burner and tubes have been installed, slide the double-
wide reflectors one at a time onto the hangers. Fasten the FIRST hanger nearest the burner to
the reflector with a sheet metal screw up through the hole in the tab at each end of the hanger.
SEE FIGURE 12A
As each successive reflector is installed, the ends of the reflectors will overlap to provide con-
tinuous coverage over the entire tube system. The overlapping joints
with sheet metal screws - Note that for both horizontal and angle mounting, the
tube must be level along its length. Improper mounting can result in overheating of controls
and combustible materials.
Reflector extensions can be added to the heaters as an option. See Figure 15 and instructions
