CGt venting
When removing boiler from existing
common vent 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.
a.
Seal any unused openings
system.
b.
Visually inspect the venting system
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
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
Follow the operating instructions. Adjust
thermostat so appliance will operate continuously.
e.
Test for spillage
5 minutes of main burner operation. Use the flame
of a match or candle.

Failure to follow all instructions can
result in flue gas spillage and carbon
monoxide emissions, causing
severe personal injury or death.
Inspect existing chimney before
installing boiler. Failure to clean or
replace perforated pipe or tile lining
will cause severe personal injury or
death.
Do not install the CGt 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.

at draft hood relief opening after
f. After it has been determined that
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 conditions of use.
Any improper operation of common venting system
should be corrected so the installation conforms with
the National Fuel Gas Code, ANSI Z223.1–latest
edition. Correct by resizing to approach the minimum
size as determined using the appropriate tables in Part
11 of that code. Canadian installations must comply
with B149.1 or B149.2 Installation Code.
Chimney or vent requirements
1. Venting must be installed according to Part 7, Venting
of Equipment, of National Fuel Gas Code, ANSI
Z223.1–latest edition and applicable building codes.
Canadian installations must comply with B149.1 or
B149.2 Installation Codes.
2. See table on page 63 for minimum chimney

or vent sizes. A chimney or vent
should extend
cap at least 3 feet above the highest
where it passes through a roof of a building
point
and
a t least 2 feet higher
building within a horizontal distance of 10 feet.
chimney or vent must not extend less than the
distances stated above.
3. A lined chimney is preferred and must be used
when required by local, state, provincial and
national codes, laws, regulations and ordinances.
Vitreous tile linings with joints that prevent
retention of moisture and linings made of
noncorrosive materials are best. Advice for flue
connections and chimney linings can be obtained
from local gas utility.
Type B
pipe or single-wall vent pipe may be used as a liner.
4. Cold masonry chimneys, also known as outside
chimneys, typically have one or more walls exposed
to outside air. When any atmospheric gas-fired
boiler with automatic vent damper is vented
through this type of chimney, the potential exists
for condensation to occur. Condensation can
damage a masonry chimney. Weil-McLain
recommends the following to prevent possible
damage.
a. Line chimney with corrosion-resistant metal
liner such as AL29-4C® single-wall stainless steel
or B-vent. Size liner per National Fuel Gas Code
ANSI Z223.1–latest edition.
b. Provide drain trap to remove any condensate.
