6-A. COMMON VENT TEST
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.
1. Seal any unused openings in the common venting system.
2. Visually inspect the venting system for proper size and horizontal pitch and determine there is no blockage or
restriction, leakage, corrosion and other deficiencies which could cause an unsafe condition.
3. Insofar as the 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 fireplace
dampers.
