(Replaces pg. 2 in instruction manual.)
CONGRATULATIONS!
You have just purchased one of the finest water heaters on the market
today!
This installation, operation and instruction manual will explain in detail the
installation and maintenance of your new 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.
This manual should be kept with the water heater.
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.
Intelligent Diagnostic Control to prevent burner/pilot operation with
restricted airflow.
Spark Igniter
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.

status
160°F and 180°F control
Figure 2
The gas control knob is set to the “OFF” position when shipped from the
factory. Remember that lower temperature settings are more energy
efficient. Adjust the temperature by turning the gas control knob. It is
suggested that the starting point setting not exceed approximately 120°F
(48.9°C) or “Hot” setting on the thermostat.
DANGER
Hotter water increases the risk of scald injury. Scalding may occur within five
(5) seconds at a temperature setting of 140F (60C). To protect against hot
water injury, 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 fail to
shut off, turn off the manual gas control valve to the appliance 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.

BURNER FLAME CHECK
(Replaces pg. 20 in instruction manual.)
These models are equipped with self adjusting air mixture and do not
have an adjustable air shutter. At periodic intervals, a visual check of the
main burner and pilot flames should be made to determine if they are burning
properly. The main burner flame should light smoothly from the pilot. The
burner flame should be soft and undefined. After five minutes of burner
operation the burner face should be glowing orange and emitting an orange
flame.

THE FOLLOWING INSTRUCTIONS ARE FOR INSTALLATION OF:
GAS WATER HEATERS SUITABLE FOR WATER (POTABLE)
HEATING AND SPACE HEATING
(Replaces pg. 27 in instruction manual.)
All piping components connected to this water heater for space heating
applications must be suitable for use with potable water. In Massachusetts,
space heating piping length must not exceed 50 feet.
1. Toxic chemicals, such as those used for boiler treatment, must not be
introduced into potable water used for space heating.
2. This water heater must not be connected to an existing heating system
or component(s) previously used with a non-potable water heating
appliance.
3. When the system requires water for space heating at temperatures higher
than required for other means, such as an ASSE approved mixing valve
must be installed to temper the water for those uses in order to reduce the
scald hazard potential.
Please refer to figure 5 and figure 6 for suggested piping arrangements.
