Removing from existing vent

When removing a boiler
from an 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
venting system.
b. Visually inspect the venting system
size and horizontal pitch and determine there is
no blockage or restriction, leakage, corrosion and
other deficiencies which could cause an unsafe
condition.
c.
Test vent system
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
Follow the lighting 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, or smoke from a cigarette,
cigar, or pipe.
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

GV special vent system

Vent system

The GV boiler requires a special vent system, designed
for pressurized venting with likelihood of condensation
in the vent. This is referred to as ANSI Z21
.
Condensing
You may use any of the vent systems covered by the
GV venting supplements included in the instruction
manual envelope. The GV vent starter tee is a special
item designed only for the GV boiler, available from
each vendor. Do not attempt to connect the vent to the
GV boiler with any other means.
DO NOT
different systems. The vent system
could fail, causing leakage of flue
products into the living space,
causing severe personal injury or
death.
Vent termination and
combustion air supply
The GV boiler may be vented through the roof or
through a side wall. Follow the appropriate vent
supplement for the vent system chosen. The maximum
vent length depends on boiler size. Refer to the vent
supplement to verify vent length will be acceptable.
Combustion air for the GV boiler may be from inside
or ducted directly to the boiler from outside. For
outside air (direct vent installation), two options are
available for the flue/air termination. The air supply
must terminate at the same location as the
ALWAYS
flue, using either:
1. Vertical direct vent installation. Obtain the
Through-Roof or Through-Unused Chimney Kit
and supplement. Find additional information in
the vent supplement for the venting material
chosen.
2. Sidewall vent/air termination. This requires the
Weil-McLain
GV Vent/air Intake Termination Kit
Refer to the instructions packed with the kit and
the vent supplement for the venting material
chosen.
Installations above 5,500 feet altitude
must be direct vent if sidewall vented.
