Only venting components manufactured by MHSC may
be used in Direct Vent systems.
Flex Vent pipes
Before joining the flex vent pipe to the unit, apply a bead
of high temperature sealant* (provided) to the 4” (102
mm) pipe exiting the fireplace. Secure flex vent pipe in
place with a hose clamp (provided).
*Be sure the flex pipe overlaps at least 1” (25 mm) onto
the collars of the fireplace and termination. If the termina-
tion has an internal bead, be sure to overlap and secure
1” (25 mm) past the bead.
* Be sure the vent is actually crushed before proceeding.
Apply a tug to be sure the vent will not slip off the collars.
Repeat process with 7” (178 mm) flex vent pipe. The same
procedure must be performed on the vent side.
