Figure 29: Typical Vent System
9. Design vent system for sea level input.
10. Provide adequate ventilation of Boiler Room. See
Section I: Pre-Installation.
11. Never pass any portion of vent system through a
circulating air duct or plenum.
G.
If an Existing Boiler is Removed:
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
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 a summer exhaust fan. Close
fireplace dampers.
4. Place in operation the appliance being inspected.
Follow the Lighting (or Operating) 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 candle, or smoke from a cigarette, cigar or
pipe.
6. After it has been determined that each appliance
remaining connected to the 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 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
, NFPA
54/ANSI Z223.1. When resizing any portion of the
common venting system, the common venting
system should be resized to approach the minimum
size as determined using the appropriate tables in
Part 7 and Part 11 in the
National Fuel Gas Code
,
NFPA 54/ANSI Z223.1.
placed in operation, while the other appliances
remaining connected 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 determine there is no
blockage or restriction, leakage, corrosion, or 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 remaining connected to the common
