d. Sometimes you wiii repiace a common vented
appliance. Make sure common vent size is cor­
rect for aJl appliances connected to it. If you re­
move a furnace from a common vent without
replacing it, the vent will likely be too large for
remaining appliances. See Venting Addendum.
e. The following steps shall be followed with each
appliance remaining connected to common vent­
ing system placed in operation, while other ap­
pliances remaining connected to common venting
system are not in operation.
1. Seal any unused openings in common vent­
ing system.
2. Visually inspect venting system for proper
size and horizontal pitch and determine there
is no blockage or restriction, leakage, corro­
sion and other deficiencies which could
cause an unsafe condition.
3. Insofar as is practical, close all building doors
and windows and all doors between space
in which appliances remaining connected to
common venting systems are located and
other spaces of building. Turn on clothes
dryers and any appliances not connected to
common venting system. Turn on any ex­
haust fans, such as range hoods and bath­
room exhausts so they will operate at maxi­
mum speed. Do not operate a summer ex­
haust fan. Close fireplace dampers.
4. Follow Operating Instructions. Place appli­
ance being inspected in operation. Adjust
thermostat so appliance will operate con­
tinuously.
5. After it has been determined that each ap­
pliance remaining connected to common
venting system properly vents when tested
as outlined above, return doors, windows,
exhaust fans, fireplace dampers and any
other gas-burning appliance to their previous
conditions of use.
6. If improper venting is observed during any
of the above tests, common venting systems
must be corrected.
NOTE: Follow current National Fuel Gas
Code ANSI 2223.1/NFPA 54 to correct im­
proper common vent operation. Any common
vent resizing must approach minimum size
determined by using Venting Addendum.
