Attention:
Clearance to combustible construction cannot be
reduced during course of construction. For the safe operation
of the nished replace, these clearances must be followed
when building the framework for the chimney system.
Note that the most important aspect of the installation is
maintaining the minimum required clearances to combustible
materials according to the chimney pipe manufacturer’s
recommendations, otherwise a potential re hazard may occur.
Warning:
do not interchange chimney manufacturer’s parts
with any other parts except those speci cally required by
the chimney manufacturer’s recommendations otherwise a
potential hazardous condition may be created.
Attention:
When choosing a Chimney System it must meet
the following requirements:
Designed for installation in accordance with the National Fire
Protection Standard and UL 103.
Meets the requirements of NFPA 211.
Designed in accordance with ICC Codes.
Optional:
Assuming you have sections of vertical pipe that are more than
10’ (ten feet) measuring between elbows, you must insert – at
midpoint – a chimney stabilizer. When installing the stabilizer,
pull out the support straps with a good amount of tension and
hammer to the frame.
