Stainless vent manufacturer’s wall thimble part numbers are shown in Table 7.5. Note that concentric vent has a “zero” clearance to combustibles and therefore does not require the use of wall thimbles.

Exception: Vertical runs of concentric pipe in an unused chinmey (Figure 7.36) need only be supported at the terminal and at the base of the run. • Support stainless steel venting as called for by the vent manufacturer’s instructions.

Removing an Existing Boiler From a Common Chimney Read this only if the BWC boiler is replacing an existing boiler that is being removed from a common chimney. This section does not apply to the installation of a BWC boiler. 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, leakage, corrosion and other deficiencies which could cause an unsafe condition. (c) Insofar as practical, close all building doors and windows and all doors between the space in which all theappliances 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 asummer exhaust fan. Close fireplace dampers. (d) Place in operation the appliance being inspected. Follow the lighting instructions. Adjust ther...
