18 Common venting guidelines
Do not common vent with the vent pipe of any other boiler or appliance. However,
when an existing boiler is removed from a common venting system, the common
venting system is likely to be too large for proper venting of the appliances remaining
connected to it. At the time of removal of an existing boiler, the following steps shall
be followed with each appliance remaining connected to the common venting system
placed in operation, while the other appliances remaining connected to the common
venting system are not in operation:
(a) Seal any unused openings in the common venting system.
(b) Visually inspect the venting system for proper size and horizontal pitch and
determine there is no blockage or restriction, leakage, corrosion and other
defi ciencies which could cause an unsafe condition.
(c) Insofar as is practical, close all building doors and windows and all doors between
the space in which the appliances remaining connected to the common venting
system are located and other spaces of the building. Turn on clothes dryers and any
appliance not connected to the common venting system. Turn on any exhaust fans,
such as range hoods and bathroom exhausts, so they will operate at maximum
speed. Do not operate a summer exhaust fan. Close fi replace dampers.
(d) Place in operation the appliance being inspected. Follow the lighting instructions.
Adjust thermostat so appliance will operate continuously
(e) Test for spillage at the draft hood relief opening after 5 minutes of main burner
operation. Use the fl ame of a match or candle, or smoke from acigarette, cigar or
pipe.
(f) 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 condition of use.”
(g) 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 CAN/CSA B149.1, Natural Gas and Propane Installation Code. When resizing
any portion of the common venting system, the common venting system should
be resized to approach the minimum size as determined using the appropriate
tables in Appendix F in the National Fuel Gas Code, ANSI Z223.1/NFPA 54 and/
or CAN/CSA B149.1, Natural Gas and Propane Installation Codes.
