(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.
