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)

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  
Flushing  
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.

FIGURE 20: T&P Valve Test  
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-

Water heater is noisy:  
1. The heater makes sizzling and hissing noises operating.  
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.
