GENERAL INFORMATION ON ASSEMBLING

THE TWIST LOCK VENT PIPES

When using CFM Majestic twist lock pipe it is not neces- sary to use silicone to seal the twist lock joints. The only areas that need silicone are the collars on the fireplace, the telescoping pipe (if used) and the horizontal termina- tion connection (when necessary).

To join the pipes together, simply align the beads of the male end with the grooves of the female end and while joining the two together, twist the pipe until the flange on the female end touches the external bead on the male end. Secure the joints with three sheet metal screws.

To make easier to assembly, we suggest putting lubri- cant (vaseline or similar) on the male end of the twist lock pipe.
