Hanger Placement and Suspension
WARNING
!
Suspension of the heater must conform to applicable codes referenced in the Safety section and
these instructions.
1
Lay all radiant tubing out in the following order. Position tubes in approximate location (see Figure
3.2).
• 10 ft. 5” O.D. CNG combustion tube with liner. The tube ends are non-specific as to which
direction they must be installed.
• 4” O.D. double-swaged aluminized radiant emitter tube. The tube ends are non-specific as to
which direction they must be installed.
• 4” O.D. aluminized radiant emitter tube(s).
2
Connect the CNG combustion tube with liner to the 16” burner tube by using the 4” tube clamp
(TP-21B).
Important!
The 10 ft. 5” O.D. CNG combustion tube with liner must be placed as the first tube
downstream of the burner control box.
3
Place a 4” elongated tube hanger (TP-19E) on the tapered CNG combustion tube with liner’s 4” O.D.
end. The spacing between the burner control box mounting brackets and the 4” tube hanger should
be 2’-4”.
4
Mark locations for hanging points.
NOTE:
If the available hanging points do not allow for the recommended spacing then the addition of
new hanging points will be necessary.
• The space between the first two hangers placed on the first tube should be approximately 8’-10”.
• The space between hangers thereafter, one per tube, should be approximately 9’-8”.
Hanger Placement and Suspension
Improper suspension of the tube heater may result in collapse and being crushed.
Always suspend from a permanent part of the building structure that can evenly
support the total force and weight of the heater.
Failure to maintain minimum clearances to combustibles may result in fire and/or
explosion, property damage, serious injury, or death. Always maintain minimum
clearances and post clearance safety limit signs or the clearance safety tag where
needed.
