2. Inspect the venting system for proper size and horizontal pitch, as required in the National
Fuel Gas Code, ANSI Z223. 1/NFPA 54 or the CSA B149.1, Natural Gas and Propane Installation
Codes and these instructions. Determine that there is no blockage or restriction, leakage,
corrosion and other defi ciencies which could cause an unsafe condition.
