Venting - Bradford White Magnum D75T125E3N Installation & Operation Manual

The venting system must be installed properly follow ing 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 w ater heater installation before connecting to the
venting system. All joints in the vent connector must be securely fastened w ith screw s 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 w ater heater. If the venting system w as 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 w ith another gas appliance. Do not
vent this w ater heater into the venting system of another gas appliance designed to vent under positive
pressure.
The w ater 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 w ater heater installation, the burner and venting system must be checked for proper
operation w ith 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 draw n into the drafthood. Do not use the w ater 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 Follow ed 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 the screws with 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- 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.
