tion of listed equipment or materials as meeting the require-
ments for Relief Valves and Automatic Shut-off Devices for
Hot Water Supply Systems, ANSI Z21.22.
1. A clear space of 457mm (18 in.) should be allowed in
front of the heater to allow access to the controls and
elements.
2. A clearance of 305mm (12 in.) is sufficient clearance
from the top of the heater to adjacent surfaces.
3. It is suggested that the heater be located in the center of
the water system or close to the point-of-use requiring
the most hot water.
Important: Only a new temperature and pressure relief
valve should be used with your water heater. Do not use an
old or existing valve as it may be damaged or not adequate
for the working pressure of the new water heater. Do not
place any valve between the relief valve and the tank.
4. The water heater should be located in an area not sub-
ject to freezing temperatures.
5. Water heaters located in unconditioned spaces (i.e.,
attics, basements, etc.) may require insulation of the
water piping and drain piping to protect against freezing.
6. The drain and controls must be easily accessible for
operation and service.
The T&P Valve:
•
•
Must be connected to an adequate discharge line.
Must not be rated higher than the working pressure
shown on the data plate of the water heater.
The Discharge Line:
•
Must not be smaller than the pipe size of the relief valve
or have any reducing coupling installed in the discharge
line.
This water heater is not intended for space heating
applications.
•
Must not be capped, blocked, plugged or contain any
valve between the relief valve and the end of the dis-
charge line.
Must terminate a maximum of 152mm (6 in.) above a
floor drain or external to the building.
Must be capable of withstanding 121°C (250°F) without
distortion.
Temperature and Pressure (T&P) Relief
Valve
All water heaters must be installed with a proper tempera-
ture and pressure relief valve. In the United States this valve
must be design certified by a nationally recognized testing
laboratory that maintains periodic inspection of the produc-

Must be installed to allow complete drainage of both the
valve and discharge line.
Must not discharge so as to come in contact with any
electrical part or wiring.
Closed System/Thermal Expansion
During the heating cycle of the water heater, the water
expands causing pressure inside the water heater to
increase. The water utility supply meter may contain a
check valve. This will create a closed water system. If the
pressure in a closed water system exceeds 1034kPa (150
PSI), water will discharge from the temperature and pres-
sure (T&P) relief valve. This is the normal safety function of
a relief valve and indicates the proper functioning of the
valve. Only if the discharge from the relief valve is continu-
ous or for an extended period of time does this indicate a
malfunction of some sort. Should this occur, have the oper-
ation of the heater checked by a technician qualified to do
so. Frequent operation of the T&P valve can result in a build
up of natural mineral deposits on the valve seat, rendering
the valve inoperative. Should this happen, the valve needs
to be replaced. To prevent this from happening install a
diaphragm-type expansion tank, that is suitable for potable
water, on the cold water supply line. The expansion tank
must have a minimum capacity of 6 litres (1.5 USG.) for
every 190 litres (50 USG) of stored water and be rated for
1034kPa (150 PSI) or the working pressure of the water
heater. NEVER PLUG OR REMOVE the T&P valve.
Under no circumstances is the manufacturer to be held
responsible for any water damage in connection with
this water heater.
IMPORTANT:
This water heater must be installed strictly in accordance
with the instructions enclosed, and local electrical, fuel
and building codes. It is possible that connections to the
water heater, or the water heater itself, may develop
leaks. IT IS THEREFORE IMPERATIVE that the water
heater be installed so that any leakage of the tank or relat-
ed water piping is directed to an adequate drain in such a
manner that it cannot damage the building, furniture, floor
covering, adjacent areas, lower floors of the structure or
other property subject to water damage. This is particular-
ly important if the water heater is installed in a multi-story
building, on finished flooring or carpeted surfaces. GSW
WILL NOT ASSUME ANY LIABILITY for damage caused
by water leaking from the water heater, pressure relief
valve, or related fittings. Select a location as centralized
within the piping system as possible. In any location
selected, it is recommended that a suitable drain pan be
installed under the water heater. This pan must limit the
water level to a MAXIMUM depth of 45mm (1 3/4 in.) and
have a diameter that is a minimum of 50mm (2 in.) greater
than the diameter of the water heater. Suitable piping shall
connect the drain pan to a properly operating floor drain.
Important: Do not plug or remove the temperature
and pressure relief valve.
WARNING
Excessive Weight Hazard
Use two or more people to move and install
water heater.
Failure to do so can result in back or other
injury.
Unpacking the Water Heater
Important: Do not remove any permanent instructions,
labels, or the data label from the outside of the water heater
or on the inside of panels. Remove exterior packaging and
place installation components aside. Inspect all parts for
damage prior to installation and start-up. Completely read
and understand all instructions before attempting to assem-
ble and install this product. After installation, dispose of
packaging material in the proper manner.
FIGURE 3: Drain Pan
WARNING!
Closets without drains and carpeted areas are examples of
unsuitable locations for any water heater. Select a location
as centralized within the piping system as possible. The
heater should be located in an area not subject to freezing
temperatures. If this heater is to be installed directly on car-
peting, the carpeting must be protected by a metal or wood
panel beneath the heater, extending beyond the full width
and depth of the heater by a minimum 80mm (3 in.). If the
heater is installed in a closet or alcove, the entire floor must
be covered by the panel. This panel must be strong enough
to support the weight of the heater full of water without
breaking. Failure to heed this warning may result in a fire
hazard.
Important: Strictly follow the installation instructions
before making electrical connections.
Piping Installation
Piping, fittings, and valves should be installed according to
the installation drawing (Figure 4). If the indoor installation
area is subject to freezing temperatures, the water piping
must be protected by insulation. Water supply pressure
should not exceed 80% of the working pressure stated on
the water heater’s data plate. If the supply pressure is high-
er than this limit, a pressure limiting valve with a bypass
must be installed in the cold water inlet line. This should be
placed on the supply to the entire building in order to main-
tain equal hot and cold water pressures.

the water heater. If the heater is located a long distance
away from the electrical supply, the wire size of the branch
circuit should be increased. The voltage measured at the
heater should not be less than 3% lower than what is meas-
ured at the supply. If your calculated value does not appear
in the table, substitute the next highest rating listed in the
table.
1. Ensure the element marking and rating plate data corre-
spond with the electric service available.
2. Install a branch circuit directly from the main service
panel to the water heater. The wiring of this circuit must
be of adequate size for the length of run and the load
(see Table 3).
Installation Check List
Check Here
1. Are the fuse and wire sizes correct?
2. Is the certified relief valve installed?
3. Were steps taken to prevent water damage in
case of leaks?
4. Has the relief valve been piped to a suitable
drain point?
5. Is the relief valve discharge unobstructed?
6. Is the heater completely filled with water?
7. Is the cold water supply valve open?
If the answer to the above are yes, turn on the
power and enjoy all the hot water you need, all the
time.
3. A ground wire must run from the green ground screw
provided at the electrical connection point in the heater
junction box to the ground connection at the service
panel.
4. Final connections are made in the control panel box on
the heater.
5. The heater you have received is internally wired. A spe-
cific wiring diagram for each heater is located inside the
control panel. All internal wiring is colour-coded and con-
nections must be made as shown in the wiring diagrams
(Figures 5-10 for Canada, Figures 11-16 for USA).
Fuses
Components in the power circuit are protected by fuses. For
voltage supplies up to 480V, the fuses are rated for 30
amperes, class G. For voltage supplies of 600V, the fuses
are rated for 15 amperes, class G. Replace fuses with same
size, type and rating only.
Note: These fuses are not required or installed in water
heaters sold in Canada.
Phase Conversion (USA only)
To Single Phase
If the heater is shipped for connection to a three-phase elec-
trical service, it may be connected to a single-phase electri-
cal service of the same voltage by making the following
changes:
1. Disconnect all the blue wires and all the yellow wires
from Terminal Block L3.
2. Reconnect all the blue wires to Terminal Block L1 (with
the black wires).
3. Reconnect all the yellow wires to Terminal Block L2 (with
the red wires).
4. Connect incoming power to Terminal Blocks L1 and L2.
To Three Phase
If the heater is shipped for connection to a single-phase
electrical service it may be connected to a three-phase elec-
trical service of the same voltage by making these changes:
1. Disconnect all the blue wires from Terminal Block L1.
2. Disconnect all the yellow wires from Terminal Block L2.
3. Reconnect the blue wires and the yellow wires to
Terminal Block L3.
4. Connect incoming power to Terminal Blocks L1, L2, and

Temperature Control
CAUTION
All electric water heaters feature fully automatic controls to
regulate the water temperature. The thermostat supplied
with the water heater may be either an immersion or a sur-
face mounted type. Both types of thermostats use contact
relays to energize the electric heating elements. The ther-
mostats are located in the bottom control panel. The ther-
mostats are factory set to 60°C (140°F) to reduce the risk of
scalding. Water temperature adjustments for the immersion
type thermostat can be made by turning the temperature
adjustment dial, located on the outside of the lower control
panel, to the desired temperature setting. Water tempera-
ture adjustments can be made to the surface mounted ther-
mostat by first turning off the electric power supply to the
water heater and removing the bottom control panel cover.
Using a screwdriver, turn the thermostat dial to the desired
temperature setting. The water heater is equipped with a
surface mounted high limit control located under insulating
material in the top control panel. If for any reason the water
temperature becomes excessive, the high limit will de-ener-
gize the heating element circuit. Once the high limit has
been activated it must be manually reset by pushing in the
red reset button located on the high limit. The cause of the
excessive temperature should be determined and correct-
ed.
Hydrogen gas can be produced in a hot water system
served by this heater that has not been used for a long
period of time (generally two (2) weeks or more).
Hydrogen gas is extremely flammable and can ignite
when exposed to a spark or flame. To reduce the risk of
injury under these conditions, it is recommended that the
hot water faucet be opened for several minutes at the
kitchen sink before using any electrical appliance con-
nected to the hot water system. Use caution in opening
faucets. When hydrogen is present, there will probably be
an unusual sound such as air escaping through the pipe
as the water begins to flow. There should be no smoking
or open flame near the faucet at the time it is open.
Water Heater Sounds
During the normal operation of the water heater, sounds or
noises may be heard. These noises are common and may
result from the following:
1. Normal expansion and contraction of metal parts during
the periods of heat-up and cool-down.
2. Sediment build up in the tank bottom will create varying
amounts of noise and may cause premature tank failure.
Drain and flush the tank as directed under “Draining,
Flushing and Sediment Removal”.
WARNING
Hot water produced by this appliance can cause severe
burns due to scalding. The hazard is increased for young
children, the aged, or the disabled where water tempera-
tures exceed 52°C (125°F). Use tempering valves in the
hot water system to reduce the risk of scalding at point-of-
use such as lavatories, sinks and bathing facilities. Such
precautions must be followed when this heater is operat-
ed in combination with dishwashing or space heating
applications.
WARNING
Water temperature over 52°C (125°F) can cause
severe burns instantly or death from scalds.
Children, disabled and elderly are at highest risk of
being scalded.
Feel water before bathing or showering.
Temperature limiting valves are recommended.

POWER.
Filling the Water Heater
1. Do not turn the power on until all the following steps,
including Startup steps, have been completed.
2. Make sure the drain valve is closed.
3. Open a hot water faucet associated with the system.
4. Open the cold water supply valve.
NOTE: When filling, avoid water leakage. Do not allow the
insulation of the water heater to get wet as water can cause
electrical malfunction.
5. When water runs out of the hot water faucet in a steady
stream, the tank is full.
6. Close the hot water faucet and check the system for
leaks. Repair as required and retest.
7. Connect a hose to the drain valve and route to a suitable
drain. Open the drain valve and let water run to flush out
any foreign matter that may have entered the system.
Once flushed, close the drain valve and disconnect
hose. Repeat steps 4-6.
Startup
Perform the following checks when the heater is placed into
operation for the first time.
Voltage Check: Verify that the supply voltage and the rating
plate voltage are the same.
1. Open the upper component panel cover and check all
electrical connections.
2. Remove the lower cover and the insulation for the ele-
ment compartment and check all electrical connections.
3. Turn "ON" the electrical supply to the heater.
4. Carefully watch all the components for one complete
cycle of operation to see that they function properly.
DANGER: Hazardous voltages are present in both com-
partments. Be careful not to touch any electrical connec-
tions.
5. To check the operation of the thermostat
(a) operate the thermostat manually and
(b) let the heater come to the preset temperature and
shut off automatically.
6. Turn "OFF" the electrical supply to the heater.
7. Replace all the insulation and close all covers.
8. Turn "ON" the electrical supply to the heater.

prevent water damage, the valve must be properly connect-
ed to a discharge line which terminates at an adequate
drain. Stand clear of the outlet (discharged water may
be hot) and slowly lift and release the lever handle on the
temperature and pressure relief valve (see Figure 20) to
allow the valve to operate freely and return to its closed
position. If the valve fails to completely reset and continues
to release water, immediately turn “OFF” the power and
close the cold water inlet and call a qualified service techni-
cian.
VII) MAINTENANCE
General
Do not attempt to repair water heater. Call your authorized
dealer for service. Shut off the electric power whenever the
water supply is turned off. Before calling for service, check
that:
1. The heater is properly filled.
2. The electrical supply has not been interrupted.
Draining,
Removal

and
Sediment
Temperature and Pressure
Water may contain fine particles of soil and sand which set-
tle to the bottom of a tank and thus form a layer of sediment.
If not removed, the sediment could reach the heating ele-
ments and cause them to fail. It is recommended that the
tank be drained and flushed on a regular basis to remove
any sediment that may buildup during operation. Some
maintenance and service procedures require that the heater
be drained and empty. The water heater should also be
drained if being shut down for an extended period of time.
To drain and remove the sediment from the tank:
1. Turn the electrical supply to the heater “OFF”.
2. Close the cold water supply valve.

3. Attach hose to the drain valve and route to an adequate
drain.
Cathodic Protection
CAUTION! The water being drained can be extremely
hot! The drain hose should be rated for at least 93°C
(200°F). If the drain hose does not have this rating, open the
cold water supply valve and a nearby hot water faucet
served by the system until the water flow is no longer hot.
Close the cold water supply valve and resume.
4. Open the drain valve using a flat-blade screwdriver. A
nearby hot water faucet must be opened to allow the
tank to be fully drained.
5. Open the cold water supply valve and flush the tank as
needed to remove sediment and any other foreign mat-
ter that may have entered the system. Close the cold
water supply valve when clean water flows.
6. If the heater is to remain empty for an extended period
of time, it is suggested the drain valve be left open.
When draining is complete, the hose may be removed.
7. Perform any other servicing as required.
Your water heater has been equipped with one or more
anodes that protect the glass-lined tank from corrosion and
prolong the life of the water heater. Over time, as the
anode(s) works, it slowly dissolves, exposing the steel inner
core. Once the anode(s) is depleted, the tank will start to
corrode, eventually developing a leak. Depending on water
conditions, an anode(s) can last from one to ten years.
Many localities treat their water and this can have a signifi-
cant effect on the life of your heater. Water conditioning,
such as over-softening, can accelerate the rate at which the
anode(s) is consumed. As with any water heater, it is good
practice to check the anode(s) annually to see if it needs
replacing. Do not remove this anode(s) permanently as
it will void any warranties, stated or implied. Rapid
depletion or failure to maintain the anode can leave a heater
unprotected and may result in premature failure of the
heater due to corrosion and leaks.
8. Close the drain valve, disconnect hose.
9. Follow instructions for “Filling the Water Heater” and
“Startup” when heater is ready to be put back into serv- Hot Water Odour
ice.
On occasion, and depending on your location, hot water
may develop a strong odour. This can be especially prob-
lematic in regions where the water contains sulphur, which
results in hot water having a "rotten egg" odour. If this
occurs, drain the system completely, flush thoroughly and
refill the tank. If the water odour or discoloration persists, the
anode(s) may need to be changed from magnesium to one
NOTE: If the water heater is going to be shut down for an
extended period, drain the tank as directed in “Draining,
Flushing and Sediment Removal”. Ensure that the cold
water supply valve is closed and the drain valve left open.

•
The accumulation of sediment or lime scale may be the
cause. The sounds are normal; however, the tank bot-
tom and elements should be cleaned. Follow the instruc-
tions given in “Draining, Flushing and Sediment
Removal”.
2. Some of the electrical components of the water heater
controls make noises.
•
Most of these are normal. Contactors will "click" or snap
as the heater starts and stops, transformers and con-
tacts often hum.
Water leakage is suspected or apparent:
Refer to “Leakage Checkpoints” (Figure 21) to locate poten-
tial leakage points.
1. Make sure the heater drain valve is fully closed.
2. Discharge from the outlet of the T&P relief valve may
indicate:
•
•
•
Faulty relief valve.
Excessive water temperature.
Excessive water pressure.
A common cause of relief valve leakage is excessive water
pressure. This condition is often caused by a "closed sys-
tem”. A closed system has a check valve in the inlet system
that prevents the expanded hot water volume to equalize
pressure with the main system. If a relief valve does not
release this pressure, it will damage the water heater or
plumbing system.
3. Remove the cover and insulation from the element com-
partment.
•
Examine the area around the element gasket for leak-
age.
•
Tighten the elements if necessary. If tightening the ele-
ments does not stop the leak it may be necessary to
replace the gaskets.
IF YOU CANNOT IDENTIFY OR CORRECT THE SOURCE
OF MALFUNCTION
1. Turn the electrical supply to the heater “OFF”.
2. Close the cold water supply valve.
3. Call a qualified service technician.

For its GSW and John Wood water heaters and storage boosters ("Unit"), GSW Water Heating ("GSW") warrants that, upon
receipt of a properly verified Warranty claim within the Warranty Period, it will, at its election, repair or replace: units which leak or parts which are defective
in material or workmanship, subject to the terms and conditions set forth in this certificate. GSW will not assume any expense or liability for unauthorized
returns, nor repairs made by a person who has not been authorized by GSW or one of its authorized dealers. GSW Units/parts must be replaced with GSW or
John Wood products to be eligible for Warranty. This Warranty is available to the original owner of a Unit installed within the boundaries of continental United
States, of Canada, or their territories. Consumers must retain point-of-sale proof of purchase to validate warranty entitlement. This Warranty does not
cover components not manufactured by GSW, such as oil burners, which carry the warranty given by the manufacturer thereof, copy of which warranty GSW
will make available, to the extent supplied by the manufacturer, without recourse to GSW.
THERE ARE NO WARRANTIES WHICH EXTEND BEYOND THE DESCRIPTION ON THE FACE HEREOF. THIS EXPRESS
WARRANTY IS, WHERE PERMITTED BY LAW, IN LIEU OF AND EXCLUDES AND REPLACES ALL OTHER CONDITIONS,
WARRANTIES, GUARANTEES, REPRESENTATIONS, OBLIGATIONS OR LIABILITIES OF GSW OF ANY NATURE OR KIND,
EXPRESS OR IMPLIED, HOWEVER ARISING (WHETHER BY CONTRACT, CONDUCT, STATEMENT, STATUTE, NEGLI-
GENCE, PRINCIPLES OF MANUFACTURER'S LIABILITY, OPERATION OF LAW OR OTHERWISE) WITH RESPECT TO THE
UNIT OR ITS FITNESS FOR A PARTICULAR PURPOSE, MERCHANTABILITY, INSTALLATION, OPERATION, REPAIR OR
REPLACEMENT. GSW EXPRESSLY DISCLAIMS ANY AND ALL IMPLIED WARRANTIES. IN NO EVENT WILL GSW'S LIA-
BILITIES EXCEED THE COST OF THE DEFECTIVE PART(S) OR UNIT. GSW WILL NOT PAY FOR ANY TRANSPORTATION,
LABOUR, INSTALLATION, OR OTHER INCIDENTAL COSTS ASSOCIATED WITH THE REPAIR OR REPLACEMENT OF A
DEFECTIVE PART OR UNIT.
This warranty and GSW's obligations shall be construed and determined in accordance with the laws of both the Province of Ontario, and of Canada in force
therein. This Warranty does not affect specific legal rights of a consumer under applicable law, except to the extent that such rights may be waived or replaced,
and the provisions hereof are deemed to be amended to the extent necessary. The unenforceability of any provision, in whole or in part, of this Certificate shall
not affect the remaining provisions. Any and all repair and/or replacement of part(s) or Unit are the sole and exclusive remedy available against GSW.
LIABILITY OF GSW COVERED BY THIS WARRANTY IS CONDITIONAL UPON THE FOLLOWING:
1. The Unit shall be installed in accordance with all manufacturers' instruc- 7.
