WARNING
All installations of boilers and venting should be done only by a qualifi ed expert and in accordance
with the appropriate installation manual. Installing or venting a boiler or any other gas appliance with
improper methods or materials may result in serious injury or death due to fi re or to asphyxiation from
poisonous gases such as carbon monoxide which is odorless and invisible.
12
When an existing boiler is removed from a common venting
system, the common venting system is likely to be too
large for the proper venting of the appliances remained
connected to it. If this situation occurs, the following test
procedure must be followed:
REMOVAL OF BOILER FROM VENTING SYSTEM
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.
Seal an unused opening in the common venting
1.
system.
Visually inspect the venting system for proper size and
2.
horizontal pitch and determine there is no blockage or
restriction, leakage, corrosion and other defi ciencies
which could cause an unsafe condition.
Insofar as is practical, close all building doors and
3.
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.
Turn on clothes dryers and any other appliance not
connected to the common venting system. Turn on
any exhaust fans, such as range hoods and bathroom
exhausts, so they operate at maximum speed. Do
not operate a summer exhaust fan. Close fi replace
dampers.
Place in operation the appliance being inspected. Follow
4.
the lighting instructions. Adjust thermostat so appliance
will operate continuously.
Test for spillage at the draft hood relief opening after
5.
5 minutes of main burner operation. Use the fl ame of
a match or candle, or smoke from a cigarette, cigar or
pipe.
After it has been determined that each appliance
6.
remaining connected to a common venting system
properly vents when tested as outlined above, return
doors, windows, exhaust fans, fi replace dampers and
any other gas burning appliances to their previous
condition of use.
Any improper operation if the common venting system
7.
should be corrected so the installation conforms with
the National Fuel Gas Code, ANSI Z223.1/NFPA 54,
and/or the Natural Gas and Propane Installation Code,
CAN/CSA B149.1. 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 Chapter 13
of the National Fuel Gas Code, ANSI Z223.1/NFPA 54,
and/or the Natural Gas and Propane Installation Code,
CAN/CSA B149.1.
NFPA 54/ANSI Z223.1, National Fuel Gas Code and NFPA/
ANSI 211, Chimneys, Fireplaces, Vents and Solid Fuel
Burning Appliances. These codes contain information on
special gas vents for Category II, III and IV appliances,
vent sizing, location, air space clearances to combustibles
and safe installation practices. The gas vent installer
should be familiar with these Federal Codes as well as
Local Codes and Regulations.
General Information Gas Vents And Appliances:
By Federal Codes, gas appliances are categorized by
the pressure and temperature of the fl ue gas vented
from the appliance. Category I and II appliances are
natural draft (draft hood) vented, with high fl ue gas
temperatures (Category I), and low fl ue gas temperatures
(Category II). Category III and IV appliances are fan
forced vents with high temperature (Category III) and
low temperature (Category IV) fl ue gasses. Appliance
effi ciency is directly related to fl ue gas temperature.
Higher effi ciency appliances remove more heat from the
gas, so they will have lower temperature fl ue products.
When fl ue gas temperatures are lowered, corrosive
condensates may form in the gas vent or in the appliance.
Condensates may form in Category II, III, IV appliance
vents, so special, corrosive resistant venting systems are
required for higher effi ciency appliances.
APPLICABLE FEDERAL CODES
!
WARNING
Vents for Category I appliances may not be
suitable for use with Category II, III, or IV
appliances because condensate may corrode
the vent.
!
WARNING
Vents for Category III appliances may not be
suitable for use with Category I appliances
because fl ue gas temperatures may be too
high.
