Support Components
ROOF SUPPORT
The roof support is supplied as a kit complete with two side
plates for fixing to the roof trusses, a band to give lateral
support to the chimney as it passes through the roof, and 3
self tapping screws, which are secured to the chimney through
the band to give a load bearing capacity. When the plates
are installed above the roof trusses as in Fig.1 the maximum
number of pipes, which may be suspended from the roof
support is 6 x 1m pipes. When the plates are attached below
the trusses as in Fig.2 the maximum number of pipes, which
may be suspended is 4 x 1m pipes.
1.
The band should be lowered down over the top of the ICS
pipe, and positioned so that the the side plates are resting
on top of the roof trusses as in Fig.1 or below the roof
trusses in the case of Fig. 2. The recommended position is
always as per Fig.1 where circumstances allow this solution.
2.
The band should then be tightened using the nut and bolt
provided.
3.
Using the holes pre-drilled in the roof support band, drill
3mm holes in the outer case of the chimney section (drill bit
should be set for a depth no greater than 10mm to avoid
any damage to the liner of the chimney)
4.
Use the self tapping screws provided to secure the clamp
band to the outer casing of the chimney section.
Please note: It is the responsibility of the installer to ensure that the truss to which the roof
support is being attached is load bearing and capable of withstanding the weight of the system
being installed.
