CF ROOF SUPPORT
The CF Roof Support can be used with either the CF chimney
or the SS chimney. The Roof Support is located on top of the
joists and is installed after a Radiation/Dust Shield (SS
Model) or an Intermediate Joist Shield (CF Model) is installed
(when required). See figures 17 & 18. Install two carriage
bolts per chimney plate in the square holes. Bend the plate
to suit the curve of the chimney. Using the plate as a
template, drill 3/32" holes in the casing. Attach the plates
using the stainless sheet metal screws provided. Attach the
roof bracket to the chimney plates using the installed
carriage bolts. Set the assembly into position and adjust and
tighten the carriage bolts. Screw the plate to the joist using
the six (6) large wood screws per bracket. The Resupports
can hold up to 9m (30') of chimney, 6m (20') of which can be
suspended.
