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 AT THE SIDE OR
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) NOTE: Correctly locate hangers to support the system
 Each tube & reflector section requires 2 hangers
 Hangers should be located not less than 2 inches (5 cm) nor more than 22 inches
(
56 cm) away from the edge of any tube coupler
 See Figure 7 page 14, and Hanger Location Table page 41
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.
3) Suspend the first two hangers from the structure.
 Locate the first hanger so that there will be 6 inches (15 cm) between the first hanger
and the tube flange
