Installation / Operation Instruction Manual

Venting continued-
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.
WARNING
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”.
