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

)
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 mechanical-
ly 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
•
Locate the second hanger within 6 to 24 inches (15 to 60 cm) from the swaged end of
