LD3 Series
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. 4” O.D. or 4” to 3” O.D. titanium treated combustion chamber.
• 3” O.D. aluminized radiant emitter tube(s) if applicable.
2 Connect the female end of the titanium combustion chamber to the 16” burner tube by
using the 4” stainless steel tube clamp (TP-220).
Important! The 10 ft. titanium alloy treated combustion chamber must be placed as the first tube
downstream of the burner control box. The combustion chamber has an orange identification
sticker located on the swaged end of the tube.
3 Place a 4” tube hanger (TP-19B) on the tapered titanium combustion chamber’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 additional
hangers (P/N: TP-19B(4”) or TP-1079(3”)) may be necessary.
• The spacing between the burner control box mounting brackets and the first hanger should be
approximately 2’-4”.
• 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 clearance 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.
