Suspension System - Schwank STV-JZ Owner's Manual

8. SUSPENSION SYSTEM

1) Survey the available structural supports, considering the system configuration and heat require-
ments 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 labour and materials
b) Consider that the heater will expand in length approximately ½ to 1inch for every 10 ft of
system length – the greater the firing rate, the greater the expansion
2) Tube system hangers must be located: 1) in line; 2) at a common height with the tube system
level; and 3) approximately 116" apart.
a) NOTE: It is important that the tubes in the system are installed in alignment horizontally
(level) and vertically (in line) – this will help prevent tube separation
3) #8 Jack Chain or equivalent is recommended for suspending the heater
a) Connect the chain to the structure using hardware as illustrated in FIGURE 8 or by other
mechanically sound means
b) If rigid devices such as rods are used for suspension, swing joints or other means must be
provided to allow for system expansion (approximately ½ inch to 1inch for every 10 ft of
system length).
4) Two types of hangers are provided to suspend the tube system – see FIGURES 3 & 4
a) Plate hangers support the tubes and reflectors at each end of the tube system
b) Webbed hangers support tubes and reflectors at each tube junction
5) Please NOTE that each hanger has a 'flat' side and a 'cavity' side – FIGURE 3
