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 thermostat (TruTemp or ThermoControl Plus) 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.

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.

WARNING
WARNING “”
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.

Installation must conform with all local, state, provincial and national code requirements includ-
ing the current latest edition ANSI Z223.1 (NFPA 54) in the U.S.A. and B149.1 installation
code in Canada, for gas burning appliances and equipment. The latest edition Electrical Code
ANSI/NFPA N0 70 in the U.S.A. and PART 1 CSA C22.1 in Canada must also be observed.
The heating system must have gas piping of the correct diameter, length, and arrangement to
function properly. For this reason, a layout drawing is necessary.
This heater must be mounted with at least the minimum clearances between the heater and
combustibles as shown in FIG-1, TABLE 1, Page 3. It is the installer’s responsibility to ensure
that building materials with a low heat tolerance which may degrade at lower temperatures are
protected to prevent degradation. Examples of low heat tolerance materials include vinyl sid-
ing, fabrics, some plastics, filmy materials, etc.
Positioning of lights, sprinkler heads, overhead doors, storage areas, gas and electrical lines,
parked vehicles, cranes and any other possible obstruction or hazard must be evaluated prior
to installation.
: The lower ‘jaw’ of the burner cabinet swings down to provide
convenient service access to burner components. Provide a minimum clearance from any wall
or obstruction of 6 inches (15 cm) to the access end of the burner housing, and a minimum of
24 inches (61 cm) to any ONE side to allow servicing of burner, blower and controls. (see Fig-
ure 2) - the minimum clearances to combustibles must always be maintained.

The radiant tube heater can be installed in configurations as illustrated in FIGURE 4 (below)
with a maximum of two 90° tube system elbows per heater. The use of elbows reduces the to-
tal maximum vent allowable by 5 feet for each 90°. (See Section 11 : Flue venting)
The 90° elbow kit (JS-0528-UE) is complete with one 90° elbow, one tube coupler, and one re-
flector end cap. For a 180° elbow two x 90° kits combine to create a 180°. The reflector must
be end-capped each side of an elbow - See FIGURE 6
: : A minimum length of straight radiant tube must be
connected to the burner prior to any elbow as follows:
• 200 Mbh (60 kW) = 30 ft (7.6 m) prior to elbow
• 160 Mbh (45 kW) & 130 Mbh (38 kW) = 20 ft (6 m) prior to elbow
• 90 Mbh (23 kW) = 15 ft (4.6 m) prior to elbow
• 60 Mbh (18 kW) a minimum of 10 ft (3 m) straight tube before elbow.

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) Tube system hangers must be located: A) straight in line; B) at a common height (level);
and C) at appropriate distances along the heater length - .
a) NOTE: It is important that the tubes in the system are installed in alignment horizontally
(level) and vertically (in line) – this will ensure system integrity
3) Hardware with a minimum 90 lb. (41 kg) work load must be used at the first burner end
hanger, and with a minimum 60 lb. (27 kg) at all other hanger suspension points. A #2 Lion
Chain (equivalent or heavier gauge) is typically used to suspend the heater.
a) Connect to the structure using typical hardware as illustrated in FIGURE 5 (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.
4) Hangers are provided to suspend the tube/reflector system – see FIGURES 6 & 7
• The hangers supplied with the heater be used for heater suspension, and 2 hang-
ers are required for each tube/reflector section
• To orient the reflector from horizontal to 30°, hangers can be suspended from either of
two eye loops in the hanger - see FIGURE 6
• Hangers are positioned along the system length as indicated in FIGURE 7 & Page 41
• Dimensions from air intake to vent end are listed on Page 42

In areas prone to earthquake, or as specified on a project, install lateral and longitudinal seis-
mic restraints as indicated in Figure 15. If the heater location can be impacted by wind
(outdoors, aircraft hangars, etc) refer to High Wind Restraint Section 9.5, Figure 16.
These restraint systems indicate typical suspension of and attachment to the heater. Attach-
ment of suspension hardware to the structure will be as required by site structural conditions,
installation codes, and/or local engineering design requirements. Other material or systems of
restraint may be specified by local or national codes, or by project engineering specifications.
Schwank / InfraSave offers optional items: #2 Lion Chain 115 lb work load x 200 ft roll (PN: JL-
0800-XX); and Safety Snap Hooks (PN: JL-0800-SH = pkg 24; JL-0800-SH-B = pkg 100).
Any and all other required seismic mounting hardware is field supplied by the installer.
-LATERAL, LONGITUDINAL, AND VERTICAL
In areas with wind conditions (aircraft hangers, etc) in addition to lateral and longitudinal re-
straint the heater must be restrained from vertical movement. Suspend the heater using 3/8”
threaded rod with 3” adjustment turnbuckle through a safety ring at each hanger location.
