The periscope vent (fi gure 9), must be used in extreme cold climates defi ned as; -22°F (-30°C) sustained for
48 hours or more.
Take the building orientation and the presence of other buildings or other nearby structures into consideration
when planning the venting system location. Certain external structures could create air turbulence around the
vent termination leading to downdrafts and similar venting problems. In windy and hill locations, roof venting
may improve operations. Maximum venting length is based on 30 mph (48 km) winds, areas where higher
gusts are dominant it is suggested to shorten the horizontal vent length.
The vent and combustion air intake shall be installed so that both are located in the same wind pressure zone.
