After it has been determined that each appliance 

remaining connected to the common venting system 

properly vents when tested as outlined above, return 

doors, windows, exhaust fans, fi replace dampers and 

any other gas-burning appliance to their previous 

conditions of use.
Any improper operation of the common venting system 

should be corrected so the installation conforms with 

the National Fuel gas Code, ANSI Z223.1/NFPA 54, 

and/or the Natural Gas and Propane Installation Code, 

CAN/CSA B149.1.  When re-sizing any portion of the 

common venting system, the common venting system 

should be re-sized to approach the minimum size 

determined using the appropriate tables in Chapter 13 

of the National Fuel Gas Code, ANSI Z223.1/NFPA 54, 

and/or the Natural Gas and Propane Installation Code, 

CAN/CSA B149.1.

Install the vent damper to service only the single 

appliance for which it is intended. If improperly 

installed, a hazardous condition, such as an explosion 

or carbon monoxide poisoning, could result.
Do not install the vent damper on vent pipe curve.

Do not run wires near high temperature surfaces. 

Use stand-off brackets if necessary.
