USE OF SEALANT
Sealant is required on vent system joints (figure 7), except Metal-Fab Sure-Seal direct vent system joints.
On longer vent runs, especially vertical runs, sealant will ensure that the combustion air enters from
outdoors, and not through the vent joints. Use high temperature sealant, available from local suppliers,
on the inner pipe joint, applying the sealant around the outside of the male part of the vent. A bead of
silicone should be used on the outside of the joint after assembly to seal the supply air. If the venting is
disconnected for servicing, be sure to follow above instructions for resealing venting when reconnecting
