J. Removing an Existing Boiler From a Common Chimney
This section only applies if this boiler is replacing an existing boiler that is being removed from a common chimney.
In some cases, when an existing boiler is removed from a common chimney, the common venting system may be too large for
the remaining appliances. 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,

(c) Insofar as practical, close all building doors and windows and all doors between the space in which all the appliances
remaining connected to the common venting system are located and other spaces of the building. Turn on clothes dryers and

(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. When re-sizing any portion of the common venting system, the common venting system
should be re sized to approach the minimum size as determined using the appropriate tables in Part 11 of the National Fuel
Gas Code, ANSI Z223.1.
