dampers and any other gas-burning appliances 
to their previous conditions of use.
7. If improper venting is observed during any of 
the above tests, the venting system must be 
corrected by a contractor qualified in the 
installation and service of gas-fired equipment 
or your local gas supplier.  If the venting must 
be resized, use appropriate tables in (US)

revision, National Fuel Gas Code (US) or 
Standard CSA B149.1 Natural Gas and

must be in accordance with the appropriate 
local codes and the NFPA 54/ANSI Z223.1 - 
latest revision, National Fuel Gas Code (US) or 
Standard CSA B149.1 Natural Gas and
