Flue Pipes used for SCF-9 Models
■ When the flue duct(including extension) passes
through a combustible wall or ceiling with
combustible materials, it should be insulated with
1" or thicker insulation and then set apart from
the wall or materials by 2" or more. When it
passes through the ceiling, include an opening for
inspection of the flue.
■ If the air supply duct is separated from the flue
duct, the total length of the flue duct should be
10-feets or less and with 2 or less elbows.
■ The connection of the air supply hose must be
sealed by the wire clamp to prevent any air loss.

Installation of the Flue
In the connection of the flue duct and the flue
elbow, an O-ring must be inserted to prevent
leaks.
■ Do not use any aluminum duct as an extension.
Use extension duct sets or elbows available
through your Quietside distributor.
■ The flue duct which carries combustion waste gas
should be firmly secured by the clamp so that it
will not loosen due to vibration. The parts where
the band clamp is not used should be sealed with
aluminum tape.
