SECTION III: GENERAL INFORMATION
FEATURES
The Bradford White EVERHOTIGE series tankless water heater is a high output, high efficiency
appliance, which heats the water continuously as hot water is being drawn for use. Unlike tank type
storage water heaters, this water heater does not store hot water. The burner operates whenever there is
a demand for hot water and is off when the water flow stops. Hot water is continuously supplied for any
length of time required, as long as the specified flow rates are not exceeded. There is no need to set the
temperature higher than required for sufficient capacity. The EVERHOT water heater has sufficient
capacity to supply several hot water faucets simultaneously. The hot water flow capability will be
dependent upon the temperature of the outlet water selected. More detail can be found under the
“Temperature Adjustment” section of this Installation and Operating Instruction Manual. Your plumbing
professional should determine your hot water requirements before installing this water heater to be sure
the capacity is sufficient for your application.
The IGE series water heaters are designed to be installed outdoors on an outside wall. The
water heater is compact (23 5/8” (60 cm) H x 13 3/4” (34.9 cm) W x 8 7/8” (22.6 cm) D) and
mounts on an outside wall using the supplied wall bracket. No indoor space is needed and the
water heater can be mounted at a height convenient for servicing.
The weight is less than 50 pounds (23 kg) and can be installed by 1 person.
The burners ignite within 3 seconds of water flow (1/2 gallon/minute (1.9 L/m) minimum) by direct
spark ignition. There is no standing pilot.
A variable speed combustion air blower forces the combustion air supply into the burner
compartment.
No venting system required. For outdoor installation only.
An optional recess box is available which allows the water heater to be recessed into an outside
wall and conceal the piping behind a cover for a more attractive installation. The box enclosure
dimensions are: 40 ½” H x 14 ¾” W x 9 ½” D. Contact your Bradford White supplier to order this
optional accessory.
The burner flame is continuously monitored and modulated to match the heating requirements of
the water flow. Temperature and flow sensors continually monitor the water flow and outlet water
temperature and adjust the burner and combustion air blower to maintain temperature.
The included, remotely mounted Main Control may be conveniently located near the point of use
and is adjustable from 98-160F for residential models (IGE-199R series), or 98-185F for
commercial models (IGE-199C series). In addition to the Main Control, up to two optional
controls are available for setting the temperature in the bathroom fixtures or other remote
locations.
All the controls also display fault codes if the water heater malfunctions to assist with servicing
the water heater.
The heat exchanger coil is provided with anti-freeze heaters for cold climate conditions for
protection as low as -30F (-34C). Solenoids should be installed to drain the water heater in the
event of a power failure.
The water heater is very quiet in operation.

SECTION IV: INSTALLATION INSTRUCTIONS
WARNING
This water heater must be located in an area where leakage of the heat exchanger coil,
water line connections, or the pressure relief valve will not result in damage to the area
adjacent to the water heater or the outside building structure.
WARNING
INSTALLATION OF THIS WATER HEATER REQUIRES ABILITY EQUIVALENT TO
THAT OF A LICENSED PLUMBER. 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.

Lime Condition Warning Signal:
If the EVERHOT water heater is operated under hard water conditions without a water conditioner, the
error code “LC” may flash on the remote temperature display. This code means the heat exchanger coil
is beginning to accumulate scale deposits and MUST be flushed (see Section IX, “Flushing Procedure for
Lime Scale Removal…”). Contact your installer for a qualified service technician to flush the heat
exchanger. A water conditioner may be needed to prevent this condition from reoccurring.
NOTICE
Failure to flush the appliance when “LC” is flashing will cause damage to the heat exchanger. Damage
caused by lime or scale build up is not covered by the water heater warranty.
INSTRUCTIONS FOR CONNECTIONS
1. BEFORE PROCEEDING WITH THE INSTALLATION, CLOSE THE MAIN WATER SUPPLY
VALVE. After shutting off the main water supply, open a faucet to relieve the water line pressure
to prevent any water from leaking out of the pipes while making the water connections to the
water heater. The COLD water inlet and HOT water outlet are identified on the bottom casing of
the water heater. Make the proper plumbing connections between the water heater and the
plumbing system to the house. All soldering materials and piping must be compatible with
potable water. Unions should be installed on both the hot and cold water lines for future servicing
and disconnection of the water heater. Install a shut-off valve in the cold water supply line.

12
2. In order to service the water heater in the event the heat exchanger needs to be flushed from lime
deposits, tee fittings with shut off valves and service connections to hoses should be installed.
Also install a shut off valve to the hot water supply to isolate the service tee fittings. A plumbing
installation kit, which includes these fittings and a pressure relief valve, is available from your
supplier. Refer to piping diagrams (fig. 2-5) at the end of Section V.
3. Install a pressure relief valve on a tee connection from the hot water outlet piping from the water
heater. Refer to the piping diagrams (fig. 2-5) and the warning for the Pressure Relief Valve at
the end of Section V on Water Connections.
4. In cold climates where piping can freeze during an extended power failure, drain solenoid valves
should be installed on the cold and hot water supply lines to allow water to drain from the water
heater when power is interrupted. Refer to the piping diagram “Recommended Piping for Power
Failure Freeze Protection” (fig. 3) at the end of this Water Connections Section and contact your
Bradford White dealer if assistance is needed.
5. If this water heater is installed in a closed water supply system, such as the one having a back-
flow preventer in the cold water supply, provisions must be made to control thermal expansion.
DO NOT operate this water heater in a closed system without provisions for controlling thermal
expansion. Warranties do not cover damages from thermal expansions such as pressure bulges
and/or deformities. Your water supplier or local plumbing inspector should be contacted on how
to control this situation.
6. Purge the cold water line prior to connecting to the water heater to remove debris. Debris will
clog the mesh strainer of the inlet filter. The inlet strainer prevents debris from damaging the flow
sensor or clogging the coil. It may need to be cleaned periodically and should be cleaned after
the installation. DO NOT operate the water heater without the filter in place.
7. After installation of the water lines, open the main water supply valve and fill the water heater.
While the water heater is filling, open several hot water faucets to allow air to escape from the
water system. When a steady stream of water flows through the faucets, close them and check
all water connections for possible leaks.
8. This water heater may also be connected to a circulating pump or storage tank for increased flow
capacity during high demand periods. Refer to the suggested piping diagrams (fig. 4-5) at the
end of Section V on Water Connections to be used as a guide.
9. Commercial installations may require more than one water heater piped together in a manifold to
supply enough capacity for high temperature and high water flow applications. Special controls
are available from your Bradford White supplier for operating more than one water heater
together. These controls stage the operation of the water heaters for the flow rates and control
the amount of flow through each water heater. Order part# 239-44511-00 for the electronic
manifold control for the first and second water heater and part# 239-44512-00 for the wiring
harness for each additional water heater to be controlled. Instructions are included with these
parts. Use the piping diagram in figure 5 in Section V as a guide.
NOTICE
Take care when using pipe dope or thread sealant tape to avoid clogging the inlet screen and water
flow sensor. Wipe off excess pipe dope from threads before connecting to the water heater.
Commercial dishwashers will require either more than one water heater or a storage tank to supply a
sufficient volume of hot water.

13
Recommended Piping for a Basic Installation
Fig. 2

14
Recommended Piping for Power Failure Freeze Protection
As long as electrical power and gas are supplied to the EVERHOTwater heater, freeze protection is
provided to the heat exchanger and piping inside the water heater with ambient temperatures as cold as
-30F (-34C), when protected from direct wind exposure. In the event of a power failure at temperatures
below freezing, the water heater must be drained of all water to prevent freeze damage. The water
heater may be drained manually, or automatically, through the installation of the optional solenoid valves
as shown in the following illustration. The drain solenoids are recommended for very cold climates to
prevent water heater freeze damage where power failures from ice and windstorms occur.
The electrical connections for the two solenoids must be tied to the 120 volt main power supply terminals
provide on the PCB board. When the electrical power to the water heater fails, the ¾” solenoid on the
cold water inlet pipe closes, stopping water flow into the water heater. The ¼” solenoid opens, allowing
the water heater and connected piping to drain. Make sure the piping from the drain solenoid is run to a
suitable drain or outside the building to prevent water damage.
Drain Solenoid Piping (Fig. 3)
CAUTION
All piping located outside the building must be insulated and wrapped with heat tape to prevent freezing.

Note: The Primary Circulator for the water heating loop must be sized for 21 GPM @ 35 Ft. Head.

17
PRESSURE RELIEF VALVE
Keep clear of the 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 pressure, install pressure protective equipment required by
local codes, but not less than a 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 pressure relief valve must be marked with a maximum set pressure not to exceed the
maximum working pressure of the water heater. The pressure relief valve rating must not be
less than the hourly rating of the water heater
Install the pressure relief valve into a tee connection from the hot water outlet of the water
heater.
Note: Some models may already be equipped or supplied with an installed pressure relief
valve. Verify that the pressure relief valve complies with local codes. If the 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 pressure relief valve will exit within
six (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 four (4) inches (10.2
cm) be provided on the side of the water heater for servicing and maintenance of the
pressure relief valve.
Do not place a valve between the pressure relief valve and the hot water outlet!
WARNING

18
SECTION VI: GAS CONNECTIONS
WARNING
Connect this water heater only to the type of gas as shown on the rating plate. Use clean black iron
pipe or equivalent material approved by local codes and ordinances. (Dirt and scale from the pipe can
enter the gas valve and cause it to malfunction). The inlet gas line must have at least a 3 inch (7.62 cm)
drip leg (sediment trap) installed as close to the water heater’s gas valve as possible. A ground joint
union must be installed in the gas supply line, as close to the water heater as possible, to permit
servicing of the water heater. Compounds used on the threaded joints of the gas piping must be
resistant to the action of liquefied petroleum gases/propane gas. DO NOT apply pipe dope to the gas
valve inlet and make certain that no pipe dope has become lodged in the inlet screen of the gas valve.
Extreme care must be taken to ensure no pipe dope enters the gas valve and to avoid excessive torque
when tightening the gas supply line to the gas valve. Excessive torque may result in cracking of the gas
valve housing. The suggested maximum torque is 31.5 foot lbs. (4.4 kg-m). The manufacturer of this
water heater will not be liable for any damage or injury caused as a result of a cracked gas inlet as a
result of excessive torque.
This water heater and its gas connection must be leak tested before placing the water heater in
operation. Check for gas leaks with a soap and water solution and a brush or a commercial leak

NEVER USE A MATCH OR OPEN FLAME FOR TESTING!
The water heater is not intended for operation at higher than 10.5 inches water column, for natural gas,
13.5 inches water column for L.P. supply gas pressure. Higher gas supply pressures require
supplemental reducing service regulation. Exposure to higher gas supply pressure may cause damage
to the gas controls, which could result in fire or explosion. If overpressure has occurred such as through
improper testing of gas lines or emergency malfunction of the supply system, the gas valve must be
checked for safe operation. Make sure that the outside vents on the supply regulators and the safety
vent valves are protected against blockage. These are parts of the gas supply system, not the water
heater.
WARNING
Conversion of this unit from natural gas to L.P., or L.P. to natural gas CANNOT be done in the field. If the
gas supply does not match the type shown on the water heater rating plate, then contact your supplier for
the proper water heater for the building gas supply.
CAUTION
The water heater and individual shutoff valve must be disconnected from the gas supply piping system
during any pressure testing of the system at test pressures in excess of ½ psi (3.5 kPa). The water
heater must be isolated from the gas supply piping system by closing its manual shutoff valve during any
pressure testing of the gas supply system at test pressures equal to or less than ½ psi (3.5 kPa). The
supply line must be capped when not connected to the water heater.
If copper supply lines are used, they must be internally tinned and certified for gas service.
The gas supply lines must meet all requirements of the National Fuel Gas Code ANSI Z223.1 (Latest
Edition), or in Canada CAN/CGA B149.1 Natural Gas Installation Code (Latest Edition) or CAN/CGA
B149.2 Propane Installation Code (Latest Edition). The gas supply line may need to be larger for the
EVERHOTwater heaters than a storage water heater in the case of a replacement installation. Refer to
the gas piping capacity tables at the end of Section VI (Gas Connections) and in the codes referenced
above.
A 3” (7.6 cm) drip leg (sediment trap) is required ahead of the gas inlet connection to the water heater.
See water heater installation illustration. Install a manual gas shutoff valve before the gas inlet
connection to the water heater before connecting to the gas line. A union should be installed before the
water heater gas connection for disconnection for servicing. Refer to the piping diagrams (Fig. 2-5) in
Section V, “Water Connections”.

19
Check the type of gas and the gas inlet pressure before connecting the EVERHOT water heater to the
gas supply. If the gas supply type does not match the type shown on the water heater rating plate, then
DO NOT connect the water heater. Contact your Bradford White supplier for the correct water heater.
GAS METER SIZE –NATURALGAS ONLY
Be sure that the gas meter has sufficient capacity to supply the full rated gas input of the water heater as
well as the requirements of all other gas fired equipment supplied by the meter. If the gas meter is too
small, ask the gas company to install a larger meter having adequate capacity.
GAS PRESSURE REGULATION
Minimum and maximum gas supply pressures are listed below: The minimum gas pressure specified
below is required for the full input rating specified on the water heater rating plate.
Natural Gas: Minimum: 6.0” w.c. L.P. Gas: Minimum: 10.0” w.c.
Maximum: 10.5” w.c. Maximum: 13.5” w.c.
BEFORE PLACING THE WATER HEATER IN OPERATION, CHECK FOR GAS LEAKAGE. USE SOAP
AND WATER SOLUTION OR OTHER MATERIAL ACCEPTABLE FOR THE PURPOSE OF LOCATING
GAS LEAKS.
WARNING
DO NOT use matches, candles, flame or other sources of ignition for this purpose.

Note: After determining the length of pipe required, select the pipe size that will supply the cubic feet per
hour of gas required for the input rating of the gas appliances on the line.
The formula for figuring the cubic feet per hour required is:
CFH = Gas Input of Appliance on the Line (Btu/hr)
Heating Value of Gas (Btu/Cu. Ft.)
The heating value may be obtained from the local natural gas utility

INITIAL OPERATION AND TESTING (INSTALLER ONLY)
1. Open the gas and water supply valves to the water heater.
2. Check for water and gas leaks. Use soap solution to check for gas leaks.
3. To check inlet supply pressure, remove the 1/8” NPT plug on the gas inlet supply fitting just below
the bottom casing and install a barb fitting for attaching a hose to a manometer. For checking the
gas manifold pressure, the plug is located just below the gas manifold connection inside the
control panel.

4. Turn power on (after completing electrical connections – refer to Section VII, “Electrical
Connections”) and fully open a hot water tap.
5. Measure the gas pressures to see that these are within the specified limits below:
Supply Pressure: Nat. Gas: Min.: 6”, Max.: 10.5” w.c.
L.P. Gas: Min.: 10”, Max.: 13.5” w.c.
Manifold Pressure: Nat. Gas: 3.4” w.c. High Fire, 0.6” w.c. Low Fire
L.P. Gas: 5.1” w.c. High Fire, 0.9” w.c. Low Fire
6. Turn off the hot water faucets. Disconnect the electrical power to the water heater. Remove the
pressure gauges and replace the plugs. Check for gas leaks around the plugs.
7. Replace the front control panel. Restore electrical power to the water heater.
NOTICE
If the gas supply pressure is below the specified value, check the gas piping to insure that it is the correct
size for all the gas appliances on line. Check the supply pressure with all the gas appliances in operation.
The manifold pressure will vary with the water flow rate. Several hot water faucets may need to be
opened with the temperature control set on the highest setting in order to get maximum high fire manifold
pressure. If the manifold pressure is below the specified value and there is sufficient water pressure and
flow, be sure the inlet gas pressure is within the specified limits before attempting to adjust the manifold
pressure.
