All the brackets on the burner tube, except,
the bracket adjacent to the U-Bend end,
should have spaced U-Bolts. All middle
brackets on the fan tube should have nuts
and washers on both sides of the bracket.
This is to allow the U-Bolt to be tightened
whilst still allowing a 3mm gap for the
tube to expand.
Slide the bracket assemblies along the tubes
to the correct position, in the correct order
(15-25kW models have a different first
bracket). Refer to detailed assembly draw-
ing (Figure 41 to Figure 50) for more details.
Note:
Do not tighten any of the nuts at this stage.
Models 15-25kW burner bracket and
models 30-50kW all brackets - M8
U-Bolt. Models 15-25kW remaining
brackets all M6 U-Bolts.
Example spaced U-Bolt locations.
