each appliance. Adjust thermostat so appliance will operate continuously.

e)Check the pressure at a pressure tap located 12 in. above the bottom joint of the first vertical vent pipe. Pressure should be anywhere between -.01 to -.08 in. WC.

f)After it has been determined that each appliance remaining connected to the common venting sys- tem properly vents when tested as outlined above, return doors, windows, exhaust fans, fireplace dampers and other gas burning appliances to their previous conditions of use.

g)Any improper operation of the common venting system should be corrected so that the installation conforms with the latest edition of the NFGC (US) and the B149 Installation Code (Canada). When re-sizing any portion of the common venting sys- tem, the common venting system should be re-sized to approach the minimum size as deter- mined using the appropriate tables in Appendix G in the NFGC (US) and Appendix B of the B149 Installation Code (Canada).
