All remaining 'U' bolts on the RETURN
TUBE should also be tightened to
achieve a minimum torque setting of 15Nm².
All remaining 'U' bolts on the FIRING
TUBE and the first 'U' bolt on the
FIRING TUBE on 2 module variants, should be
left loose and locked in place with a locknut to
achieve a 3mm clearance above the tube to
allow for thermal expansion (see sketch below).

2.2.3 Turbulators
There are various lengths of turbulators
(G) for the vision range. Identify correct lengths
prior to assembly. We recommend turbulators
are inserted into tubes prior to hanging.
Insert short 976mm turbulator into burner firing
tube from U BEND END.
For models 15, 20 and 25: Insert 3400mm
turbulator into return tube from U BEND END.
For models 30, 35 and 40: Insert one 2600mm
turbulator into return tube from U BEND END
and one 2600mm turbulator into return tube
from OPPOSITE END.
For models 45 and 50: Insert one 3040mm
turbulator into return tube from U BEND END
and one 3400mm* turbulator into return tube
from OPPOSITE END. * Nat Gas only

2.2.4 Couplers
For fixing the U bend. Locate and position tube
couplers (D) Slide the coupler over the
components ensuring that the rivet stop has
butted up to the tube end and the pre-fitted bolts
engage in the pre-cut holes so that the socket
heads are FACING INWARDS.
Moving between the two set pins, tighten both
ensuring that equal pressure is applied to each
set pin in turn.

2.2.5 Coupler Bellows
For adjoining tubes on 3 and 4 module heaters,
locate and position the coupler (Q) onto the
ends of the tubes after firstly positioning a clamp
on both ends. Slide each clamp onto the bellow
ends.
Moving between the two set pins, tighten both
ensuring that equal pressure is applied to each
set pin in turn.
section 2.2.7.2.3
There is one bellow located on the firing
tube on models 30, 35 & 40:
There are two bellows located on each
tube on models 45 and 50:
Due to the length of models 45 and 50,
the coupler bellows are assembled onto
the tube ends ONCE the two halves of the
heater have been fully assembled and
hung in position see "Final Fixings"
