Suspending The System - Schwank S100 Installation & Owner's Manual

8. SUSPENDING THE SYSTEM - GENERAL
Inadequate or improper suspension of the tube heater can result in collapse of
the system, property damage, and personal injury or death.
It is the installer's responsibility to ensure that the hardware and structural sup-
ports from which the heater is suspended are sound and of adequate strength
to support the weight and expansion forces of the heater.
Consider that the heater will expand in length as much as 1/2 inch (12.5 mm) or more for every
10 ft (3 m) of system length – typically the greater the firing rate, the greater the expansion.
1) Survey the available structural supports, considering the system configuration and heat re-
quirements of the area to establish the optimum heater location.
a) Locating a heater directly under joists or beams, or installing supplemental steel support
rail or angle iron can substantially reduce labor and materials
2) Hardware with a minimum 60 lb. (30 kg) work load must be used at each heater suspension
point. A #8 Jack Chain or equivalent is typically used for suspending the heater.
a) Connect to the structure using typical hardware as illustrated in FIGURE 6 (below) or by
other mechanically 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) Tube system hangers must be located:
i: Straight in line
ii: At a common height (level)
NOTE: It is important that the
tubes in the system are in-
stalled in alignment horizon-
tally (level) and vertically (in
line) – this will ensure system
integrity

fastening to structure are of sufficient strength to support the system.
