SECTION V: VENTING
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.
FLUE DAMPER
Refer to Figure 6 and follow these instructions:
1. Remove the damper from the accompanying box shipped within the crate.
2. Locate the collector outlet on top of the water heater. Place the damper over the collector outlet and rotate as
necessary to a position in which the damper wiring plug can be fully engaged with the connector on the side of the
water heater.
Do not turn on electrical power to water heater until flue damper is installed and water heater is filled with water.
CAUTION
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 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”.
