Venting
(Replaces pg. 10 in instruction manual.)
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
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 hood for which it was designed with
reference to the horizontal and vertical planes. If removed, the draft hood must be
replaced in the same position and secured to the blower draft hood bracket.
NOTICE
This water heater is equipped with a draft hood. This water heater can be vented using
single wall or double wall vent connector pipe. This water heater may be vented into
Type B vent or a masonry chimney. This water heater can use either 3” or 4” venting.
Refer to the National Fuel Gas Code (latest edition) vent tables, using “NAT” columns
to determine appropriate vent configuration.
