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 flammable 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
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).

10
UHE / EIH I&O Manual
IM100205
RD: MAY 2013
RL: 03D
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 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.
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) - the minimum clearances to combustibles must always be maintained.

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.
Refer to “Clearance to Combustibles” information on pages 6 to 8, and
Figure 1 and Table 1.
*RECOMMENDED 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)

7. SYSTEMS INCORPORATING 90° ELBOWS AND 180° ELBOWS
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 10 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
IMPORTANT: Location of Elbow vs. Input: 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.

8. SUSPENDING THE SYSTEM - GENERAL - details in Section 9
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) at appropriate distances along the heater length - see Figure 7 page 15.
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 FIGURE 6
 The hangers supplied with the heater must be used for heater suspension
 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
 Dimensions from air intake to vent end are listed in TABLE 3

9. INSTALLATION OF TUBE/REFLECTOR SYSTEM
PRIOR TO PROCEEDING with the tube installation: Read and understand Section 8 -
“System Suspension”, and Fig.1 & Table 1 Clearances to Combustible Materials
Confirm that the Burner Kit and Tube Kit(s) on site are the proper match - see Section 26
i) UHE/EIH 160 & 200: Special Tube Kit & Coupling - Refer to Section 9.1, Fig 13
 160,000 Btuh models must use primary tube kit TK-P160-UL
 200,000 Btuh models must use primary tube kit TK-P200-UL
 These 20 ft primary tube kits have an uncoated stainless steel tube with flange
as the first tube, and:
 160,000 an uncoated aluminized steel tube as the second tube
 200,000 an uncoated stainless steel tube as the second tube
 The flange on the first tube is painted “WHITE” for easy identification
 DO NOT USE PRIMARY TUBE KIT DESIGNED FOR LESSER INPUT MODELS
Ii) If a turbulator is required, it is factory installed inside a clearly labeled tube as to the
position in the system that the tube must be installed - a turbulator is always lo-
cated at the vent end of the system — See Table 3
iii) ALL MODELS: INSTALL THE FIRST AND SECOND TUBES (FROM BURNER
END) WITH THE WELDED SEAM ALONG THE TUBE LENGTH FACING DOWN
1) Hangers supplied with the system must be used to suspend the system, and be:
a) Suspended at the same height = horizontal alignment of tubes in a level orientation
b) In a straight line = vertical alignment of tubes
c) Correctly spaced and oriented to the reflector to support the system - see Figures 6 & 7
2) Hardware with a minimum 90 lb. (41 kg) work load must be used at the first hanger (burner
end), and 60 lb. (27 kg) at each subsequent heater suspension point. A #2 Lion Chain
(equivalent or heavier gauge) is typically used to suspend the heater.
a) Fasten to the structure using hardware as illustrated in FIGURE 5 or by other mechani-
cally 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.

19) Lift the downstream end of the second reflector slightly, and slide the inner reflector exten-
sion under the first reflector - mate snuggly with the first reflector
20) Through the three circular hole in the outer reflector, clear away insulation to allow access
to the slotted holes in the inner reflector
21) Align the slotted holes in the first and second reflectors where they overlap - if necessary
use a screw driver or similar tool to assist in alignment of the holes
22) Fasten the two reflectors together using three nuts and bolts supplied
 TIP: To place the nut on the bolt extending down through the hole at the top of the
reflector, hold nut between thumb and finger, reach under the tube, then up and over
the far side of the tube to align the nut to the bolt protruding through the hole
23) Repeat steps 11 to 21, assembling one section of tube and reflector at a time until the sys-
tem is complete
 If a TURBULATOR is required in the system it is located at the VENT END
24) Install the reflector end cap at the vent end of the system using three nuts and bolts sup-
plied
