VENTING
This water heater has been shipped with a draft diverter for which it was
designed with reference to the horizontal and vertical planes. If removed, the
draft diverter must be replaced in the same position and secured to the jacket
top by the screws with which it was installed.
WARNING
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.
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 drafthood after several minutes of
operation. The flame from a match should be drawn into the drafthood. 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”.
