and Vent ends

1) Survey the available structural supports, considering the system configuration and heat requirements 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) ap-

proximately 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

a) Starting at the burner end of the heater: all hangers except the last plate hanger are oriented with the cavity

side of the hanger facing toward the burner end

b) The cavity side of only the vent end plate hanger faces the vent - FIGURE 3
