Table 1A Corrosive Contaminants and Sources

When removing a boiler from existing
common vent system:

Do not install the Knight wall mount boiler
into a common vent with any other
appliance. This will cause flue gas spillage or
appliance malfunction, resulting in possible
severe personal injury, death, or substantial
property damage.

Failure to follow all instructions can result in
flue gas spillage and carbon monoxide
emissions, causing severe personal injury or
death.

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.

a.

Seal any unused openings in the common venting system.

b. 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.

c.

Test vent system – 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.
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.

d. Place in operation the appliance being inspected. Follow

the lighting instructions. Adjust thermostat so appliance
will operate continuously.

e.

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.

f.

After it has been determined that each appliance remaining
connected to the common venting system properly vents
when tested as outlined herein, return doors, windows,
exhaust fans, fireplace dampers, and any other gas-burning
appliance to their previous conditions of use.

g.

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/CSA B149.1, Natural Gas and Propane Installation
Code. 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 11 of the National Fuel Gas Code,
ANSI Z223.1/NFPA and/or CAN/CSA B149.1, Natural Gas
and Propane Installation Code.
