2.2.4 Couplers

The couplers are used for joining radiant tubes
and U or L bends.

Slide the coupler over the tube ensuring that the
screw stop has butted up to the tube ends.
Using the 9/16” wrench to tighten the bolts.

DO NOT OVERTIGHTEN.
Moving between the four bolts, tighten each
ensuring that equal pressure is applied to each
bolt in turn. Complete assembly by drilling and
screwing self tapping retention zip screws.

2.2.5 Reflectors.

After removing the protective plastic coating
(if fitted), slip the reflectors through the hanger
brackets until they overlap each other.

The first and second reflector are fixed at the
point F by a type F reflector support bracket and
are held in place by tightening the fixing screws.

Alternate fixings of further reflectors by type S
and type F reflector brackets and space as
indicated by individual assembly sheets.



Type ‘F’ are fixed reflector brackets.



Type ‘S’ are sliding reflector brackets.

Slip the suspension brackets onto the tube
assembly. The fixed suspension point ’H’
shown on the drawings are adjacent to the
burner and secures the first suspension bracket
to the tube with a tube strap. All other
suspension brackets ’G’ shown on the
drawings, have floating suspension points.

Reflectors are fixed at point ’F’ with a reflector
support bracket and reflectors are held in
position with fixing screws. Fixed and sliding
joints alternate along the heater at the spacings
indicated on the individual heater assembly
sheets.

At this point raise the tube assembly into
position and suspend from previously fixed

chains (Working Load 100lb). Longer tube
assemblies may be raised in more than one
sub-assembly with final tube connection
made in the air.

All reflectors must be positioned/
attached to the brackets exactly as
detailed in the assembly drawings.

Each

subsequent

reflector

must

OVERLAP the previous one as shown
below and to a distance as indicated by
their individual assembly sheets.

Reflector support bracket assemblies
are fitted at each reflector joint, with the
clamp screws adjusted so that reflectors
are fixed together.
