The Multi-vent connector is capable of using stainless
steel (SST), Polypropylene or PVC/CPVC pipe. Before
installing vent pipe, verify which o-ring gasket will be
used and dispose of the other two.
NOTE: During winter months check the vent cap
and make sure no blockage occurs from build-up of
snow or ice.
Vent Terminal Location
1. Condensate can freeze on the vent cap. Frozen
condensate on the vent cap can result in a blocked
flue condition.
2. Give special attention to the location of the vent
termination to avoid possibility of property dam-
age or personal injury.
3. Gases may form a white vapor plume in winter.
The plume could obstruct a window view if the ter-
mination is installed near windows.
4. The bottom of the vent terminal and the air intake
shall be located at least 12 in. above grade, includ-
ing normal snow line.
5. Single-wall Category IV metal vent pipe shall not
be used outdoors in cold climates for venting gas-
fired equipment without insulation.
6. Through-the-wall vents for Category IV appli-
ances shall not terminate over public walkways or
over an area where condensate or vapor could
create a nuisance or hazard or could be detrimen-
tal to the operation of regulators, relief valves, or
other equipment.
6. Locate and guard vent termination to prevent acci-
dental contact by people or pets.
7. DO NOT terminate vent in window well, stairwell,
alcove, courtyard or other recessed area.
9. DO NOT terminate above any door, window, or
gravity air intake. Condensate can freeze, causing
ice formations.
10. Locate or guard vent to prevent condensate from
damaging exterior finishes. Use a 300-series
stainless steel backing plate against brick or
masonry surfaces.
