Venting
The venting system must be installed properly following all local codes or in the
absence of local codes, the latest edition of the National Fuel Gas Code (ANSI
Z223.1- latest edition), or in Canada, The Natural Gas and Propane Installation
Code (B149.1-00 latest edition). Failure to properly install the venting system
could result in property damage, personal injury, or death.
Carefully inspect the venting system of a replacement water heater installation
before connecting to the venting system. All joints in the vent connector must be
securely fastened with screws and fit tightly together. Inspect the venting system
for signs of deterioration (rust and perforation) and replace any sections that are
not in good condition.
The chimney must be lined and in good condition. Check to make sure the
venting system is properly sized for the water heater. If the venting system was
previously sized for another gas appliance that has been removed, the venting
system may now be too large. Refer to the latest edition of the National Fuel Gas
Code (ANSI Z223.1-latest edition), or in Canada, the Natural Gas and Propane
Installation Code (B149.1-00 latest edition) for the correct sizing of venting
systems and common venting with another gas appliance.
Do not vent this water heater into the venting system of another gas appliance
designed to vent under positive pressure.
The water heater should be installed as close as practical to the venting system
to minimize the vent connector length required. Refer to local codes for the
distance limitations on vent connector lengths.
At the completion of the water heater installation, the burner and venting system
must be checked for proper operation with all other commonly vented appliances
in operation. Check for spillage of flue products around the outside relief opening
of the draft hood after several minutes of operation. The flame from a match
should be drawn into the draft hood. Do not use the water heater or connected
equipment if spillage is detected until the problem is corrected. Refer to the latest
edition of the National Fuel Gas Code, or in Canada, the Natural Gas and
Propane Installation Code for complete details on the "Procedure to Be Followed
to Place Equipment in Operation".
This water heater has been shipped with a draft diverter for which it was designed with
reference to the horizontal and vertical planes, its certified category I, per latest ANSI
Z 21.10.3-2015.CSA 4.3-2015 revision. Refer to the latest edition of the National Fuel
Gas Code (ANSI Z223.1-latest edition), or in Canada, the Natural Gas and Propane
Installation Code (B149.1-00 latest edition). If removed, the draft diverter must be
replaced in the same position and secured to the jacket top by which it was installed.
This water heater must be connected to a lined masonry chimney or venting system
approved by local codes or ordinances. The vent connector used to attach the draft
diverter outlet to the chimney or approved vent must be of the same diameter as the
draft diverter outlet or larger. For proper venting in certain installations, a larger vent
connector may be needed. Consult venting tables in ANSI standard (Z223.1-or latest
edition), National Fuel Gas Code and CAN/CGA (B149.1 or B149.2-latest editions)
Natural Gas and Propane Installation Code, or local code officials for proper
application for your area.
