Heater Expansion
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. Refer to Section 13
WARNING
Venting
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. Refer to Sections 11 & 12
Gas Connection
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 tested
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. Refer to Section 13
WARNING
WARNING Start-Up ‘SMOKE’ Condition
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.
IMPORTANT THERMOSTAT SETTING FOR COMFORT
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.

Clearance to combustibles
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.
The clearance to combustible material represents the minimum dis-
tance that must be maintained between the outer heater surface and
a nearby surface. The stated clearance to combustibles represents a
surface temperature of 90F° (50C°) above room temperature. It is the
installer’s responsibility to ensure that building materials with a low
heat tolerance which may degrade at lower temperatures are pro-
tected to prevent degradation. Examples of low heat tolerance mate-
rials include vinyl siding, fabrics, some plastics, filmy materials, etc.
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.
Refer to Figure 1 and Table 1 for the certified clearances to combustibles for the appro-
priate model input/size.
WARNING
WARNING Tube “GLOW”
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.

VENT END CLEARANCE: Clearances from the vent pipe are determined by local or national
installation codes, but must not be less than 6 inches (15 cm). For ‘unvented’ installation, a
minimum distance of 48 inches (122 cm) is required from the end of heater to a combustible
surface.
In locations used for the storage of combustible materials: Signs
must be posted specifying the maximum permissible stacking height to
maintain the required clearances from the heater to the combustibles.
The signs must be posted either adjacent to the IR heating system thermostats or in the ab-
sence of such thermostats, in a conspicuous place.
For your convenience a “peel and stick” sign
is provided with this heater. Use a permanent
marker to record the required dimensions on
the sign.
To calculate the value ‘H’: (H= T- C)
 Measure the on site distance between bottom of
the heater and the floor = ‘T’ inches (cm).
 Refer to Table 1 to get the value ‘C’ that corre-
sponds to the model you are installing
 Subtract the clearance below the heater ‘C’ from
‘T’ to get value ‘H’.
 Enter this value ‘H’ on the sign.
Refer to the information for the heater model
being installed in Figure 1 and Table 1 to get
the values for dimensions ‘S’, ‘F’ and ‘B’.
WARNING
Post this sign as instructed above.
NOTE that in the above table the clearances are measured from the reflector.
It is the installer’s responsibility to ensure that building materials with a low heat tol-
erance which may degrade at lower temperatures are protected to prevent degrada-
tion. Examples of low heat tolerance materials include vinyl siding, fabrics, some
plastics, filmy materials, etc.

WARNING
Improper installation, adjustment, alteration, service or maintenance can cause
property damage, injury or death. Read and understand this installation and
operation manual thoroughly prior to assembly, installation, operation or service to
this appliance.
This heater must be installed and serviced only by a trained gas service technician.
Do not store or use gasoline or other flammable vapours and liquids in the vicinity
of this or any other gas fired appliance.
Failure to comply could result in personal injury, death, fire and/or property damage.
Do not store or use gasoline or other flammable vapours and liquids in the vicinity
of this or any other gas fired appliance.
5. PRE INSTALLATION SURVEY
It is recommended that a full heating design including heat loss calculation be conducted on
the structure or area to be heated. Heater sizing and placement must consider available
mounting height, sources of greatest heat loss, and the certified clearances to combustibles
with respect to stored material, moveable objects (cranes, vehicles, lifts, overhead doors, etc),
sprinkler system heads, and other obstructions on the site. Consideration must also be given to
vent / duct placement and the allowable combined lengths of vent and duct. Carefully survey
the area to be heated, and for best results place burner and combustion chamber in the coldest
area(s) .
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.

6. MOUNTING CLEARANCES
This heater must be mounted with at least the minimum clearances between the heater and
combustibles as shown in FIG-1, TABLE 1, Page 7. 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.
Ensure adequate clearance around the air intake at the burner to allow sufficient com-
bustion air supply to the heater.
6A. SERVICE CLEARANCE: 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 below) - the minimum clearances to combustibles must always be maintained.
For guidelines to heater placement refer to TABLE 2 (next page).
FIGURE 2

IMPORTANT: 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 ambient temperature plus 90F°
(50C°).
It is the installer’s responsibility to ensure that building materials with a
low heat tolerance which may degrade at lower temperatures are pro-
tected to prevent degradation. Examples of low heat tolerance materials
include vinyl siding, fabrics, some plastics, filmy materials, etc.

7. SUSPENDING THE SYSTEM - GENERAL
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.
Refer to Sections 13 & 14
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) 116” (295 cm) apart.- see Figure 6 next page.
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 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 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) Two types of hangers are provided to suspend the tube system – see FIGURES 6 & 7
a) Plate hangers support the tubes and reflectors at each end of the system
b) Webbed hangers support tubes and reflectors at each tube junction

FIGURE 4 SYSTEM CONFIGURATIONS
8. SYSTEMS INCORPORATING 90° ELBOWS AND 180° ELBOWS
A radiant tube heater can be installed in configurations as illustrated in FIGURE 4. (below) with
a maximum of two 90° elbows per heater. The use of elbows reduces the total maximum vent
allowable. (See Section 11 : Flue venting)
90° elbows (JS-0528-JZ) are shipped as a kit with one coupler, one reflector and one plate
hanger. For a 180° elbow, order 2 x 90° kits that connect to create a 180°. An optional kit
(JS-0504-JZ) to angle mount a reflector adjacent to an elbow is also available and must be or-
dered separately. The reflectors must be secured to each of the elbow plate hangers, See
PAGE 16 IMPORTANT: Models with input 100 Mbh x 20 ft (30 kW x 6 m) must only be in-
stalled as a straight system with no elbows allowed at the 10 ft (3 m) location.
Elbow Location / Input: A minimum run of straight radiant tube must be con-
nected to the burner before any elbow as follows: Inputs 200,000 and 175,000
= 25 ft (7.6 m); 150,000 = 20 ft (6 m); 130,000 and 110,000 = 15 ft (4.6 m); and
inputs 80,000 and 60,000 a minimum of 10 ft (3 m) straight tube before elbow.
JS-0504-JZ
Angle mounting of the reflector system either side of an el-
bow requires adapter JS-0504-JZ. The elbow always remains
in a horizontal orientation.

#11/A
Suspend with 3 chains in horizontal posi-
tion and continue installing the tubes and
reflectors to complete the system.
#11/B
When hanging a heater with a 180° el-
bow kit at 45° angle the vent run tubes
must be on top, with the burner on the
lower side.
JS-0504-JZ REFLECTOR ANGLE ADAPTER -JZ SERIES
1. A reflector angle adapter can be
installed on either side or both
sides of an elbow, depending
upon site requirements for an-
gling of reflectors
2. The angle adapter is installed on
the ‘flat’ side of the webbed
hanger (concave side of hanger
must face inward towards the el-
bow)
3. Rotate the angle adapter around
the tube to the desired angle of
the reflector - established by the
tube/reflector system hangers lo-
cated before or after the elbow
4. Align one of the holes in the angle adapter with the hole at top center of the elbow/tube
hanger
5. Bolt the angle adapter to the elbow/tube hanger through the aligned holes
6. The angle adapter will remain in place by resting on the tube
7. Attach reflector to the angle adapter with sheet metal screws

9. BURNER AND TUBE INSTALLATION
PRIOR TO PROCEEDING with the tube installation: Read and understand Section 8 -
“Suspending the System ”, and this section of “IMPORTANT SPECIAL NOTES”.
1. STS-JZ/IQ 100 x 20 ft: Special Tube Coupling - Refer to Section 9.1, Fig 15
2. STS-JZ/IQ 175 & 200:Special Tube Coupling -Refer to Section 9.2, Fig 16
These firing rates have an unpainted titanium alloy stainless steel first tube with a flange
(painted “white”), and an unpainted aluminized steel tube as the second tube; all subsequent
tubes are painted steel. The first tube (titanium alloy stainless steel ) will “glow red” while
heater is in operation - THIS IS A NORMAL CONDITION
3. IF a 90° or 180° elbow is to be installed in the system, refer NOW to Section 8 and the Elbow
Kit installation instructions supplied with the elbow kit
4. TURBULATORS: Also refer to Table page 23
155 Models (150,000 Btuh): 2 ft turbulator supplied in the Burner Kit and field installed:
 155 x 40 ft heater: Insert 2 ft turbulator in end of third tube, prior to the 10 ft turbulator
that is factory installed in the last tube (total 12 ft turbulator)
 155 x 50 ft heater: Insert 2 ft turbulator in the vent end of the last tube
 All other turbulators are factory installed inside tube(s) that are clearly labeled with in-
struction as to where the tube(s) must be installed
200,000 x 60 ft & 70 ft: Remove short piece of turbulator from the upstream end of
turbulator tube prior to installation (see sheet in Primary tube kit)
Turbulators typically install at the vent end of the heater except 175,000 & 200,000 x 70 ft -
the turbulator tube installs as the 6th tube in the system (50 to 60 ft).
ALL MODELS: INSTALL THE FIRST AND SECOND TUBES (FROM BURNER END) WITH THE
WELDED SEAM (ALONG THE TUBE LENGTH) FACING DOWNWARD
1) All hangers must be:
a) Suspended at the same height = horizontal alignment of tubes (level)
b) In a straight line = vertical alignment of tubes
c) Spaced 116" (295 cm) apart = correct spacing for reflector attachment
d) Orient hangers with the “cavity side” facing the burner end of the system (except the last
plate hanger at the vent end = the cavity side faces the vent)
2) Insert the swaged end of the first tube (tube with flange) through the 4" (10 cm) hole in the
first plate hanger (LOCATE WELDED SEAM FACING DOWNWARD)
a) Ensure the ‘cavity’ side of the hanger faces the burner end of the system
b) The distance between the tube flange and first hanger must be 4.5 inches (11.4 cm)
b) Slide a Torctite tube coupler past the swage onto the tube
 The final position of the coupler will be on the ‘burner-end’ side of the hanger
c) Guide the tube into the second hanger (webbed) – ensure the cavity side of the hanger
faces the burner end of the system
d) Position first plate hanger 2.5 inches (6.4 cm) from the tube flange – this provides access
to bolt the burner to the flange, and ensure correct spacing of consecutive system hangers
