(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 Programmable 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

in the below table, 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.

THERMOSTAT ADJUSTMENT

(Replaces pg. 19 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.

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 to decrease the

temperature setting. Rotate the thermostat dial clockwise to increase the

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 140°F (60

C). 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 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.

BURNER FLAME CHECK

(Replaces pg. 22 in instruction manual.)

Steel Burner: These models are equipped with self adjusting air mixture and do not

have an adjustable air shutter (See Figure 3). 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.

HEATING AND SPACE HEATING

(Replaces pg. 31 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 6 for suggested piping arrangements.
