Venting Components
Venting should not need to be disassembled for
normal cleaning. However, if venting is required to
be removed for any reason, this should be done by a
qualified service person only. It is imperative that
the venting system be reinstalled according to the
particular manufacturer’s specifications and this is
best performed by a professional.
Venting System Inspection
Periodic inspection of the venting system should be
performed by a qualified service person or agency at
least annually.
