When installed, these tubular radiant heaters must be able to expand, must be
level, and must be restricted from too much lateral sway. The optional hanger
kit includes 50' of chain (rated for 200 lbs) and "S" hooks. The chain must be
cut to length. A minimum of 12" (305mm) total of chain, "S" hooks, and/or
turnbuckle length is required between the tubes and the structure suspension
points.
The burner box has four suspension points. Each straight tube must have at
least one suspension point. Model VR heaters are designed so that the tube
suspension point location can be adjusted slightly to adapt to the building
structure. A straight tube adjacent downstream of an “L” or “U” tube requires
two suspension points.
Heaters should be suspended at a height that has been determined to be most
efficient for that application. Clearances to combustibles must be observed.
Refer to the installation manual for clearances and recommended mounting
heights. Description
WARNING: Improper installation, adjustment,
alteration, service, or maintenance can cause
property damage, injury or death. Read the
installation, operation, and maintenance instructions
thoroughly before installing or servicing this
equipment.
Suspension
Requirements NOTE: Although turnbuckles are not included in this hanger kit, using
turnbuckles in heater suspension is recommended for convenience in
leveling the system. Use either an Option CK12-CK18 Turnbuckle Kit, or
field-supplied turnbuckles of steel or malleable iron.
The installer is responsible for attaching the suspension points to the building and
for adequately supporting the weight of the heater. Suspension point hardware is
field supplied.
The burner/control box has two hanger brackets. To restrict lateral sway of the
heater, locate suspension points as illustrated in FIGURE 1.
