Vent Pipe System
This water heater uses a non-direct, single-pipe vent system to
remove exhaust gases created by the burning of fossil fuels. Air
for combustion is taken from the immediate water heater location
or is ducted in from the outside (see "Combustion Air Supply and
Ventilation").
This water heater must be properly vented for the removal of
exhaust gases to the outside atmosphere. Correct installation of
the vent pipe system is mandatory for the proper and efficient
operation of this water heater and is an important factor in the life
of the unit.
The vent pipe must be installed according to all local and state
codes or, in the absence of local and state codes, the "National
Fuel Gas Code", ANSI Z223.1(NFPA 54)-current edition. The
vent pipe installation must not be obstructed so as to prevent the
removal of exhaust gases to the outside atmosphere.
IMPORTANT: The use of vent dampers is not recommended
by the manufacturer of this water heater. Although some vent
dampers are certified by CSA International, this certification
applies to the vent damper device only and does not mean they
are certified for use on this water heater.
U.L. recognized fuel gas and carbon monoxide (CO) detectors
are recommended in all applications and should be installed
using the manufacturer's instructions and local codes, rules, or
regulations.
IMPORTANT: If you lack the necessary skills required to properly
install this venting system, you should not proceed, but get help
from a qualified technician.
