WARNING
This water heater needs fresh air for safe operation and must be installed so there are provisions for adequate
combustion and ventilation air. Insufficient air supply will cause a recirculation of combustion products resulting in
contamination that may be hazardous to life. This will result in carboning or sooting of the combustion chamber,
burners, and flue tubes and creates a risk of asphyxiation.
This water heater requires its own separate venting system. DO NOT connect the exhaust vent into an existing vent
pipe or chimney.
Water heater materials of construction, products of combustion and the fuel contain carbon monoxide, nitrogen
oxides, aldehydes and/or other toxic or harmful substances which can cause death or serious injury and which are
known to the state of California to cause cancer, birth defects and other reproductive harm. Always use proper
safety clothing, respirators and equipment when servicing or working nearby this water heater.
Flammable items, pressurized containers or any other potential fire hazardous articles must never be placed on or
adjacent to the water heater. Open containers of flammable material should not be stored or used in the same room
with this water heater.
Insulation blankets are not required for this water heater. This water heater meets or exceeds the ASHRAE/IES
90.1b (latest edition) standards with respect to insulation and standby loss requirements.
Hydrogen gas can be produced in an operating water heater that has not had water drawn from the tank for a long
period of time (generally two weeks or more). Hydrogen gas is extremely flammable. To prevent the possibility of
injury under these conditions, we recommend the hot water faucet to be open for several minutes at the kitchen sink
before you use any electrical appliance, which is connect to the hot water system. If hydrogen is present, there will
be unusual sounds such as air escaping through the pipes as hot water begins to flow. Do not smoke or have open
flame near the faucet at the time it is open.
WARNING
Liquefied petroleum gases/propane gas is heavier than air and will remain at floor level if there is a leak.
Basements, crawl spaces, closets and areas below ground level will serve as pockets for accumulation of leaking
gas. Before lighting, smell all around the appliance area for gas. Be sure to smell next to the floor.
IF YOU SMELL GAS:
•DO NOT try to light any appliance.
•DO NOT touch any electric switch; do not use any telephone in your building.
•Immediately call your gas supplier from a telephone in another building. Follow the gas supplier’s
instructions.
•If you cannot reach your gas supplier, call the fire department.

SECTION III: GENERAL INFORMATION
FEATURES
This water heater contains the following features:
MAIN POWER ON/OFF SWITCH – The front panel of this water heater has a lighted ON/OFF switch, which is illuminated
when the main power is turned on to indicate power to the water heater.
COMBUSTION SYSTEM – This water heater is equipped with a self-compensating negative pressure pre-mix combustion
system. As the blower operates, air is drawn in through the air intake and into a venturi, which pulls gas from the gas valve. The
gas and air is then mixed in the combustion blower and sent through the transition tube into the burner. The Direct Spark Ignition
System (DSI) then ignites the gas/air fuel mixture to produce flue products (combustion). The flame sensor signals the ignition
control board (described below), that a flame is present.
HONEYWELL INTEGRATED CONTROL – Consists of a control board and a water heater display. An attractive digital water
heater display is on the top front of the water heater for precisely setting and displaying the temperature setpoint and monitoring the
status of the water heater. Pressing the temperature UP and DOWN buttons changes the temperature setpoint. The temperature
format may be displayed in degrees F or degrees C. The water heater display will show diagnostic codes in the event the water
heater needs servicing. The temperature readings of the tank sensor can be monitored in Service Mode. Also in Service Mode, the
display can show up to 10 previous error codes to further aid in servicing the water heater.
The single control board has plug in wiring harnesses to reduce the chance of miswiring. The control board controls all ignition,
temperature, and combustion blower functions. The control board controls the combustion blower, ignition timings, and gas valve
to control the combustion system in order to maintain the desired tank temperature. The sequence of operation is described in detail
in the Diagnostic Section at the back of this Installation and Operating Instruction Manual.
ADJUSTABLE THERMOSTAT – This water heater is equipped with an adjustable thermostat to control water temperature. Hot
water temperatures required for automatic dishwasher and laundry use can cause scald burns resulting in serious personal injury
and/or death.
The temperature may be adjusted from about 70°F (21°C) to about 180°F (82°C). The thermostat was adjusted to 70°F (21°C)
before the water heater was shipped from the factory. It is recommended that lower temperatures be used to avoid the risk of
scalding. Refer to the “Warnings” and the section on SCALDING in “Section V: Water Connections.” It is further recommended,
in all cases, that the water temperature be set for the lowest temperature, which satisfies your hot water requirements for the
installation. This will also provide the most energy efficient operation of the water heater and minimizes scale formation.
Setting the water heater temperature at 120°F (49°C) will reduce the risk of scalds. Some states require setting lower temperatures
for specific installations.
The top immersion well of the single sensor control also contains a redundant sensor for the high limit (energy cutoff). The high
limit circuit interrupts the main burner gas flow should the water temperature exceed approximately 200°F (93°C). Error code “65”
will be shown on the water heater control display if the high limit temperature has been exceeded.
Should the high limit switch activate, it must be manually reset. This should only be done by a service technician after the cause of
overheating has been corrected. Refer to the section on “Accessing Service Mode on the Display” in the Diagnostic section of this
Installation and Instruction Manual.
Contact your qualified installing contractor, service provider or manufacturer listed on the rating plate if continued high limit
operation occurs.
SERVICE PANEL – The service panel is located behind the service panel access cover, which is located by the exhaust elbow near
the bottom of the water heater. This panel contains a pressure switch that monitors the pressure in the exhaust pipe in case the vent
terminal becomes blocked. A collector high limit switch is used to monitor the ambient temperature between the first pass collector
and the exhaust collector. This is a manually re-settable switch. If this switch continues to trip, please contact an authorized service
agency.

7
LATCHES – The latches allow easy access for servicing the water heater from the top. Simply remove the two latches for
servicing and re-latch upon completion. No tools are required to obtain access to the top of the water heater.
MIXING VALVE –This water heater is supplied with an ASSE approved mixing valve to reduce the potential for scald injury
when thermostat settings over 120˚F (49ºC) are used for dishwashers or other appliances. The mixing valve reduces the discharge
temperature by mixing cold and hot water in the branch supply lines. Refer to the instructions supplied with the mixing valve for
installation procedures and device specifications. The mixing valve is located inside the control compartment.
SCALDING WARNING
ASSE APPROVED MIXING DEVICE MUST BE INSTALLED
TO PROVIDE PROTECTION FROM SCALDING
This water heater can deliver scalding temperature water at any faucet in the system if installed without installing the
supplied ASSE mixing device. By setting the thermostat on this water heater to obtain an increased water temperature
without properly installing the supplied mixing device, you may create the potential for scald injury. To protect against
injury, the supplied ASSE approved mixing device (a device to limit the temperature of water to protect against scald injury
via mixing hot and cold water supply) must be properly installed in the water system. This valve will reduce point of
discharge temperature in branch supply lines.
TEMPERATURE AND PRESSURE RELIEF VALVE –
WARNING
Keep clear of the combination temperature and pressure relief valve discharge line outlet. The discharge
may be hot enough to cause scald injury. The water is under pressure and may splash.
For protection against excessive temperatures and pressure, install temperature and pressure protective equipment
required by local codes, but not less than a combination temperature and pressure relief valve certified by a
nationally recognized testing laboratory that maintains periodic inspection of production of listed equipment or
materials as meeting the requirements of the Standard for Relief Valves and Automatic Gas Shutoff Devices for
Hot Water Supply Systems, ANSI Z21.22 and the Standard CAN1-4.4 Temperature, Pressure, Temperature and
Pressure Relief Valves and Vacuum Relief Valves. The combination temperature and pressure relief valve must be
marked with a maximum set pressure not to exceed the maximum working pressure of the water heater. The
combination temperature and pressure relief valve rating must not be less than the hourly rating of the water
heater
Install the combination temperature and pressure relief valve into the opening provided and marked for this
purpose on the water heater.
Note: Some models may already be equipped or supplied with an installed combination temperature and pressure
relief valve. Verify that the combination temperature and pressure relief valve complies with local codes. If the
combination temperature and pressure relief valve does not comply with local codes, replace it with one that does.
Follow the installation instructions above on this page
Install a discharge line so that water discharged from the combination temperature and pressure relief valve will
exit within 6 inches (15.2 cm) above, or any distance below the structural floor and cannot contact any live
electrical part. The discharge line is to be installed to allow for complete drainage of both the combination
temperature and pressure relief valve and the discharge line. The discharge opening must not be subjected to
blockage or freezing. DO NOT thread, plug or cap the discharge line. It is recommended that a minimum
clearance of 4 inches (10.2 cm) be provided on the side of the water heater for servicing and maintenance of the
combination temperature and pressure relief valve.
Do not place a valve between the combination temperature and pressure relief valve and the tank!

8
CONDENSATE DRAIN – The water heater should either be raised several inches above the floor on a concrete slab or use a low
profile condensate pump to allow free drainage of condensate from the elbow drain fitting. This water heater is a condensing type
unit and requires a drain to be located in close proximity to allow the condensate to drain safely. The condensate drains from the
unit at the exhaust elbow located near the bottom of the unit. The preferred connection to the drain fitting is to use a ¾ inch (1.9
cm) PVC elbow sealed with silicone over the outside of the drain outlet and use ¾ inch (1.9 cm) PVC for the drain trap and
condensate line to a drain. Use a thick bead of silicone caulk over the outside of the drain outlet connection before assembling the
elbow. This is preferred over using the threaded tap because the larger drain line will drain more freely and if too much force is
applied to the plastic threads, the fitting may crack and cause a leak. Make sure the condensate drain line slopes down, away from
the water heater at least ⅛inch (.3 cm) per foot (.3 m) toward the drain. The condensate drain pipe must not be routed through an
area subject to below freezing temperatures. The condensate build-up will block the exhaust outlet, which will cause improper
operation. Refer to Figure 2 for the proper connection of a PVC elbow to the drain outlet and a condensate trap.
Figure 2. Condensate Elbow With Trap
CLEANOUT – All models are equipped with a cleanout opening to aid in removal of hard water deposits from the tank bottom. If
this water heater operates under hard water conditions, the following should be performed at least every 3 months: Turn off water
supply and drain the water heater. Remove the cleanout jacket cover and tank cover. When cleaning the tank, care must be taken to
avoid trying to break deposits loose as this could damage the glass lining and shorten the life of the water heater. After cleaning, re-
install the cleanout tank cover and jacket cover, and refill with water. Refer to the section, “Section X: Maintenance” in this
Installation and Operating Instruction manual for the procedures for filling and draining the water heater.
SACRIFICIAL ANODES – Four sacrificial anode rods have been installed in the tank head to extend tank life. The anode rods
should be inspected periodically for corrosion and replaced when necessary to prolong tank life. Water conditions in your area will
influence the time interval for inspection and replacement of the anode rods. The use of a water softener may increase the speed of
anode consumption. More frequent inspection of the anodes is needed when using softened (or phosphate treated) water. Contact
the installing contractor, or service provider that installed the water heater or the manufacturer listed on the rating plate for anode
replacement information.

SECTION IV: INSTALLATION INSTRUCTIONS
WARNING
INSTALLATION OF THIS WATER HEATER REQUIRES ABILITY EQUIVALENT
TO THAT OF A LICENSED TRADESMAN IN THE FIELD. PLUMBING, AIR
SUPPLY, VENTING, GAS SUPPLY AND ELECTRICAL WORK ARE REQUIRED.
DO NOT ATTEMPT TO LIGHT ANY GAS APPLIANCE IF YOU ARE NOT
CERTAIN OF THE FOLLOWING:
•Liquefied petroleum gases/propane gas and natural gas have an odorant added by the
gas supplier that aids in detection of the gas.
•Most people recognize this odor as a “sulfur” or “rotten egg” smell.
•Other conditions, such as “odorant fade” can cause the odorant to diminish in
intensity, or “fade”, and not be as readily detectable.
•If you have a diminished sense of smell, or are in any way unsure of the presence of
gas, immediately contact your gas supplier from a telephone in another building.
•Gas detectors are available. Contact your gas supplier or plumbing professional for
more information.
Liquefied petroleum gases/propane gas is heavier than air and will remain at floor level if
there is a leak. Basements, crawl spaces, closets and areas below ground level will serve as
pockets for accumulation of leaking gas. Before lighting, smell all around the appliance area
for gas. Be sure to smell next to the floor.
IF YOU SMELL GAS:
•Do not try to light any appliance.
•Do not touch any electric switch; do not use any telephone in your building.
•Immediately call your gas supplier from a telephone in another building. Follow the
gas supplier’s instructions.
•If you cannot reach your gas supplier, call the fire department.
DO NOT OPERATE THE APPLIANCE UNTIL THE LEAKAGE IS CORRECTED!
WARNING
This water heater must be located in an area where leakage of the tank, water line connections,
or the combination temperature and pressure relief valve will not result in damage to the area
adjacent to the water heater or to lower floors of the structure. When such locations cannot be
avoided, a suitable drain pan must be installed under the water heater. The drain pan depth
must be suitable for draining and collecting water, and have a minimum length and width of at
least 4 inches (10.2 cm) measured from the jacket of the water heater. The drain pan, as
described above, can be purchased from your plumbing professional. The drain pan must be
piped to an adequate drain. The piping must be at least ¾ inch (1.9 cm) in diameter and
pitched for proper drainage.

10
Sacrificial anode rods have been installed in the tank head of the water heater to extend tank life. The removal of these anodes for
any reason will nullify the warranty. In areas where water is unusually active, an odor may occur at the hot water faucet due to a
reaction between the sacrificial anode and the impurities in the water. If this should happen, alternative anodes may be purchased
from the supplier that installed this water heater. This will minimize the odor while protecting the tank. Additionally, the water
heater should be flushed with appropriate dissolvers to eliminate any bacteria.
This water heater MUST be installed indoors out of the wind and weather.
This water heater MUST NOT be installed in any location where gasoline or flammable vapors are likely to be present,
unless the installation is such to eliminate the probable ignition of gasoline or flammable vapors.
Water heaters in residential garages must be installed so that all burner(s) and ignition device(s) are located not less than 18
inches (45.7 cm) above the floor and be located, or protected , to avoid physical damage. For other installations, refer to
local codes. In the absence of local codes, the water heater must be installed in compliance with the National Fuel Gas Code,
(ANSI Z223.1-Latest Edition) or CAN/CGA B149.1 Natural Gas Installation Code (Latest Edition) or CAN/CGA B149.2
Propane Installation Code (Latest Edition).
