Assemble the heater components as shown in Figures 2a, 2b, 2c, 2d, 2e, and 2f. Optional reflector configurations are shown in (Figure

1). Install appropriated suspension hardware, beam clamps, chain or rod at predetermined locations. Adjustment of chain length will provide uniform pitch.

Couplings: Tube and tube fittings are connected by wrap-around couplings which clamp by means of a tapered, hammer-driven lock member. The starting ends of the coupling and lock member are identified by 1/4” holes which are put together when starting assembly. Be sure the tube ends are in line and tube ends butt against stop pin(s) inside coupling. The slide bar is to be hammer-driven to a point of securing the coupling snugly to the tubes. Over-driving will result in distortion of the coupling or slide bar lip to a point decreasing the holding the capability of the coupling. Coupling should be tight when the slide bar is +- 2” from the end of the coupling.

(See Figure 3)

3)Attach the wire to the hole in the tab on the adapter piece.

4)Using the wire, pull the assembled turbulator into the tube from the opposite side.

5)Pull the turbulator through until just the tab comes out. Detach the wire.

6)Bend the tab around the tubing. When installing the tube, the tab will be locked in place by the adapter.

TURBULATOR BAFFLE ASSEMBLY INSTRUCTIONS

For ease of field installation, the turbulator should be installed in the tube before hanging the system.

Use the following procedure:

1)Assemble turbulator pieces by “twisting” matching ends together.

2)Insert a long wire (11 ft. minimum) down the length of the tube.

Stk. # F106414 U-Tube Package includes:

(1) U-tube, (1) coupling and (2) reflectors. Install U-tube elbow into radiant tube sequence where plans indicate a 180° bend

(see Figure 4).
