point, moisture in the exhaust condenses 
in the vent, which can lead to accelerated 
vent corrosion. Maintain hot ue gas 
temperatures. It is recommended that the 
vent run inside the building envelope or 
inside a chase enclosure to minimize the 
vent’s exposure to cold temperatures. Be sure 
to follow all-applicable building codes and 
the requirements of the vent and appliance 
manufacturers. 
Appliance Operation: Always operate 
your appliance in accordance with the 
appliance manufacturer’s recommendations. 
However, operating the appliance at its 
lowest setting has a greater chance for 
condensate to form in the vent due to the 
low exhaust temperature. In order to help 
reduce condensate from forming inside 
the vent system, operate the appliance at 
higher temperatures when colder weather 
is encountered. Higher operation settings 
provide for warmer ue temperatures, which 
help to keep moisture suspended in the ue 
gases. 
Inspection and Maintenance: Be sure to 
inspect the appliance and vent often to 
determine if there has been any corrosion or 
damage to the system. Be sure to keep the 
venting system clean, including the tee cap (if 
applicable).
