TwIST loCk pIpeS
When using twist lock pipe it is not necessary to use seal-
ant on the joints.
To join twist lock pipes together, simply align the beads of
the male end with the grooves of the female end, twisting
the pipe until the flange on the female end contacts exter-
nal flange on the male end. It is recommended that you
secure the joints with three (3) sheet metal screws, how-
ever, this is not mandatory with twist lock pipe. Figure 11
noTe: Sealant is not required to assemble fireplace
venting. Do not use silicone sealant at the inner flue
exhaust connections.
To make it easier to assembly the joints, we suggest put-
ting a lubricant (Vaseline or similar) on the male end of the
twist lock pipe prior to assembly.
