CONGRATULATIONS!
This installation, operation and instruction manual will explain in detail the installation
and maintenance of your new High Efficiency Flammable Vapor Ignition Resistant Gas
Water Heater. We strongly recommend that you contact a plumbing professional for
the installation of this water heater.
We require that you carefully read this manual, as well as the enclosed warranty, and
refer to it when questions arise. If you have any specific questions concerning your
warranty, please consult the plumbing professional from whom your water heater was
purchased. For your records, we recommend that you write the model, serial number
and installation date of your water heater in the maintenance section in the back of this
manual.
Special Flammable Vapor Ignition Resistant System:
This water heater is equipped with a Flammable Vapor Ignition Resistant System. In
the event of improper usage or storage of gasoline or other flammable materials in the
location where the water heater is installed, the technology will resist ignition of the
flammable vapors outside the confines of the water heater.
The Flammable Vapor Ignition Resistant System Features:
Advanced Flame Arrestor Design
Re-settable Thermal Switch to prevent burner/pilot operation with restricted
airflow
Flammable Vapor Sensor
Automatic Ignition Device
Sight Window to observe operation of pilot and burner
FOR YOUR SAFETY: Activation of the Flammable Vapor Ignition Resistant System
occurs when flammable vapors are drawn into the water heater and are combusted. If
flammable vapors are detected:
Do not try to light any appliance.
Do not touch any electrical switch; do not use any phone in your building.
Leave the premises and immediately call the fire department from a
neighbor’s phone. Follow the fire department’s instructions.
Once the flammable vapor has been evacuated, contact your plumbing professional or
the manufacturer for further instructions. Replacement of a Flammable Vapor Ignition
Resistant System equipped water heater due to a flammable vapor shutdown is not
covered under the terms of the limited warranty.

Minimum Clearances
(Replaces pg. 9 in instruction manual.)
WARNING
Failure to adhere to these installation and operating instructions may create a hazard to
life and property and will nullify the warranty.
This installation must allow access to the front of the water heater and adequate
clearance must be provided for servicing and operating this water heater. The water
heater may be installed on either a combustible or non-combustible floor. If the water
heater is to be installed directly on carpeting, it must be installed on top of a metal or
wood panel (or equivalent) extending beyond the full width and depth of the water
heater by at least 3 in. (7.6 cm) in any direction or, if the appliance is to be installed in
an alcove or closet, the entire floor must be covered by the panel. If the rating plate or
the label on the front of the heater specifies minimum clearances less than those listed
below, the water heater must be installed in accordance with the minimum clearances
listed on the rating plate or the label on the front of the heater.
If it is necessary to install this water heater in an alcove, use the clearances listed in
Figure 1.
Figure 1. Minimum Clearances for an Alcove Installation.

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 Z223.1latest edition), or in Canada, The Natural Gas and Propane Installation Code (B149.100 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 Z223.1latest edition), or in Canada, the Natural Gas and Propane Installation Code (B149.100 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.

THERMOSTAT ADJUSTMENT
(Replaces pg. 20-21 in instruction manual.)
The thermostat dial is adjusted to its lowest setting when shipped from the factory.
When adjusting the thermostat, it should be remembered that lower temperature
settings are more energy efficient. To adjust the thermostat, turn the dial clockwise until
the minimum acceptable temperature is set. It is suggested that the starting point
setting not exceed the 120°F (49°C) or “HOT” setting on the thermostat.
Figure 2. Gas Valve.
The thermostat dial is set to its lowest temperature setting when shipped from the
factory. Remember that lower temperature settings are more energy efficient. Adjust
the temperature by turning the thermostat dial. It is suggested that the starting point
setting not be greater than the “Hot” mark on the thermostat dial (approximately 120°F
[48.9°C]). Rotate the thermostat dial counter-clockwise
temperature setting. Rotate the thermostat dial clockwise
temperature setting. Adjust the dial until the minimum acceptable temperature is
achieved.

DANGER
Hotter water increases the risk of scald injury. Scalding may occur within five (5)
seconds at a temperature setting of 140F (60
install an ASSE approved mixing valve in the water system. This valve will reduce
point of discharge temperature by mixing cold and hot water in branch water lines. A
licensed plumbing professional or local plumbing authority should be consulted.
Note: This water heater is equipped with an energy cut out device to prevent
overheating. Should overheating occur or the gas supply fails to shut off, turn off the
manual gas control valve to the water heater, and call a qualified service technician.
Note: Whenever the water heater is filled with cold water, condensate will form on the
cool tank surface and drops of water will fall on the hot burner and combustion
chamber surfaces producing a “sizzling” noise. Condensation is normal and does not
indicate a leak. It will disappear when the tank becomes heated.
