Combustion Air Venting
Removal of an Existing Boiler from a
Common Vent System
When an existing boiler is removed from a
common venting system, the common venting
system is likely to be too large for proper
venting of the remaining appliances. At the
time of removal of an existing boiler, the fol-
lowing steps shall be followed with each
appliance remaining connected to the com-
mon venting system placed in operation,
while the other appliances remaining con-
nected 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 deter-
mine there is no blockage or restriction,
leakage, corrosion and other deficiencies
which could cause an unsafe condition.
3. Insofar as is practical, close all building
doors and windows and all doors between
the space in which the appliances remain-
ing connected to the common venting sys-
tem 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.
4. Place in operation the appliance being
inspected. Follow the lighting instructions.
Adjust thermostat so appliance will operate
continuously.
5. Test for spillage at the draft hood relief
opening after 5 minutes of main burner
operation. Use the flame of a match or can-
dle, or smoke from a cigarette, cigar or pipe.
6. After it has been determined that each
appliance remaining connected to the com-
mon venting system properly vents when
tested as outlined above, return doors, win-
dows, exhaust fans, fireplace dampers, and
any other gas-burning appliance to their
previous condition of use.
7. Any improper operation of the common
venting system should be corrected so the
installation conforms with the National
Fuel Gas Code, ANSI Z223.1/NFPA 54
and/or CAN/CGA B149, Installation codes.
When resizing any portion of the common
venting system, the common venting sys-
tem should be resized to approach the min-
imum size as determined using the appro-
priate tables in Part II of the National Fuel
Gas Code ANSI Z223.1/NFPA 54 and/or
CAN/CGA B149, Installation codes.
Do not install the PRESTIGE Solo into a
common vent with other gas or oil appli-
ances. This may cause flue gas spillage or
appliance malfunction, resulting in possi-
ble severe personal injury, death or sub-
stantial property damage.
