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
that there is no blockage, restriction, leakage, corrosion or other deficiency, 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.
