series 2 wall mount gas-fired water boiler – boiler manual
6 Venting/air piping — general
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 re-
sizing to approach the minimum size as determined using the
appropriate tables in Part13 of that code.
Do not install the FreeStyle
®
boiler into a com-
mon vent with any other appliance. is will
cause ue gas spillage or appliance malfunction,
resulting in possible severe personal injury, death
or substantial property damage.
Existing common vent systems may be too large
for the appliances remaining connected aer the
existing boiler is removed.
Failure to follow all instructions can result in ue
gas spillage and carbon monoxide emissions,
causing severe personal injury or death.
Use ONLY the venting materials and venting
manufacturers’ components and systems ap-
proved by Weil-McLain. Follow all instructions
provided by the venting component and system
manufacturer. Failure to do so can cause ue gas
spillage and carbon monoxide emissions, result-
ing in severe personal injury or death.
When removing a boiler from an
existing common vent system
The boiler cannot be common vented with any other ap-
pliance
. When an existing boiler is replaced with a FreeStyle®
boiler, the boiler CANNOT use the existing common vent. e
boiler requires its own vent and air piping, as specied in this
manual. is may cause a problem for the appliances that remain
on the old common vent, because the vent may be too large. e
following test is intended to check for proper operation of the
appliances remaining on the old common vent system.
Vent system verication
Perform the test sequence for each appliance remaining on the
original common vent system. Operate each appliance indi-
vidually, with other appliances turned o. is procedure will
test whether the common vent system can properly vent each
appliance.
Existing vent test procedure
(The following is intended to test whether the
appliances remaining on an existing vent system will
operate satisfactorily.)
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 deciencies which
could cause an unsafe condition.
3. Test vent system — Insofar as is practical, close all build-
ing 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 replace dampers.
4. Place in operation the appliance being inspected. Follow
the operating instructions. Adjust thermostat so appli-
ance will operate continuously.
5. Test for spillage at dra hood relief opening aer 5 min-
utes of main burner operation. Use the ame of a match
or candle, or smoke from a cigarette, cigar, or pipe.
6. Aer it has been determined that each appliance remain-
ing connected to the common venting system properly
vents when tested as outlined herein, return doors, win-
dows, exhaust fans, replace dampers, and any other
gas-burning appliance to their previous conditions of use.
