Hanger Placement and Suspension
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 (P/N: BR-SIGN) where needed.
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 3.4).
• 10 ft. primary combustion chamber.
• Radiant emitter tubes.
Important! 150,000-200,000 BTU/h models must use the 10 ft. titanium alloy treated combustion
chamber as the first tube downstream of the burner control box. The combustion chamber has a
yellow identification label wrapped on the tube (remove label prior to starting up heater).
2
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) may be necessary.
• The spacing between the burner control box mounting brackets and the first hanger should be
approximately 2'-4"(0.7 m).
• The space between the first two hangers placed on the first tube, should be approximately
8'-10"(2.7 m).
• The space between hangers thereafter, one per tube, should be approximately 9'-8"(3 m).
