Figure 10: Flexible Vent in Masonry Chimney with Separate Combustion Air Intake

WARNING

DO NOT mix vent systems of differ

ent types or manufacturers. Failure

to comply could result in severe per-

sonal injury, death, or substantial

property damage.

Do NOT connect venting to a chim

ney flue that is servicing a separate

appliance designed to burn solid

fuel.

Do not insulate polypropylene vent

pipes. Excessive heat could cause

premature vent pipe failure.

NOTICE

Pressure drop for flexible polypropylene line is 20

% greater than from rigid pipe. Multiply measured

flexible polypropylene liner length by 1.2 to obtain

equivalent length.

Maximum equivalent vent length of flexible poly

propylene liner is 48 ft. (14.6 m).
Installation of a polypropylene vent system should

adhere to the vent manufacturer's installation in

structions supplied with the vent system.
