6.All joints of the vent must be tightly sealed. The inside of the vent should be free of all obstructions.
7.All vents and vent connectors must fit tightly to avoid air leaks.
8.All vent connectors connecting the furnace to the vent must be rigidly supported with hangers and straps, in order to prevent movement after installation. The vent connector must be supported every four feet for the design and weight of the material used, to maintain clearances, and to prevent physical damage.

10.All single wall vent connectors connected to the PGT & PGL Series furnaces must have all seams and joints sealed with high temperature pressure sensitive aluminum tape or silicone rubber sealant.
EXAMPLE:
1.High temperature aluminum tape, temperature rating of 400°F or more.
2.Dow Corning
Temperature rating of 450°F or more.
11.Vent connectors installed in or passing through an unheated space must be insulated with 1.0" thick foil faced fiberglass or its equivalent to prevent condensate from forming in the connector or vent.
