I) INTRODUCTION
Thank you for purchasing this storage booster tank.
Properly installed and maintained, it will provide years of
trouble free service.
The warranty on this storage booster tank is in effect only
when the tank is installed and operated in accordance with
these instructions. The manufacturer of this tank will not be
liable for any injury or property damage resulting from fail-
ure to comply with these instructions.
IMPORTANT: Read and understand these instructions
before installing and operating your storage booster tank.
Description
The JOHN WOOD series of storage booster tanks, avail-
able in 40, 50 or 80 gallon sizes, have been designed to
supply hot water for domestic use when combined with a
tankless coil boiler or other water heating source. Each tank
is equipped with an adjustable thermostat, pre-wired and
ready for connection to a circulator pump (not supplied).
These tanks are not constructed to ASME requirements and
should not be used for such applications.
II) SAFETY
Local Codes
The installation of this storage tank must be In accordance
with these Instructions and all applicable local codes. This
product is certified to comply with California and Vermont
2010 "lead free" standards.
Relief Valve Requirements
T&P Valve Check
Inspect the relief valve annually to ensure proper operation.
This involves opening the valve to check that it is flowing
freely and that there are no blockages and letting it snap
shut (see “MAINTENANCE” section).
III) INSTALLATION
Location
Locate the storage tank in a clean dry area close to the
water heating source and preferably central to the piping
system. Adequate clearance for accessibility to permit main-
WARNING
For protection against excessive temperatures and pres-
sure, install temperature and pressure protective equip-
ment required by local codes, but no less than a combi-
nation Temperature and Pressure (T&P) Relief Valve cer-
tified as meeting the requirements for Relief Valves and
Automatic Gas Shutoff Devices for Hot Water Supply
Systems, ANSI Z21.22, by a nationally recognized test-
ing laboratory that maintains periodic inspection of pro-
duction of listed equipment or materials. The valve shall
be marked with a maximum set pressure not to exceed
the maximum working pressure of the storage tank. The
T&P valve shall be rated for the BTU INPUT of the entire
system.This T&P valve may be in addition to any T&P
valve that is required on the boiler, or other energy supply
system. Install the valve into the opening provided on the
storage tank, or other approved system location. Provide
tubing so that any discharge from the valve will exit within
152mm (6 in.) above, or any distance below the structur-
al floor and cannot contact any live electrical part. The end
of the relief pipe opening should terminate near the floor
drain or other suitable location. Do not place a valve(s) or
any other blockage or restrictions between the tank and
the T&P valve.
IMPORTANT:
This storage booster tank must be installed strictly in
accordance with the instructions enclosed, and local elec-
trical, fuel and building codes. It is possible that connec-
tions to the tank, or the tank itself, may develop leaks. IT
IS THEREFORE IMPERATIVE that the storage booster
tank 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 tank 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 storage booster tank, 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 storage booster tank. 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 storage booster tank.
Suitable piping shall connect the drain pan to a properly
operating floor drain.
WARNING:
Excessive Weight Hazard
Use two or more people to move and install
storage booster tank. Failure to do so can
result in back or other injury.
CAUTION
Hydrogen gas can be produced in a hot water system
served by this storage tank 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.

tenance and service must be provided. Water lines and the
storage tank should be protected from freezing tempera-
tures. Do not install the storage tank in outdoor unprotected
areas. It is desirable to have a floor drain nearby to permit
easy draining if necessary.
Circulator Pump
A circulator pump is not supplied. Use only a bronze body
model rated for 110/120 volts, 60Hz. Install in accordance
with the pump manufacturer’s instructions using standard
plumbing practices.
Plumbing Connections
The main parts and features of your storage booster tank
are identified in Figure 1. Install plumbing according to
Figure 2 for single storage tank and according to Figure 3
for multiple storage tank systems.
1. Ensure the storage tank is level before starting installa-
tion.
2. Install circulation loop as shown using 19mm (¾ in.)
copper pipe.
3. Install the cold water supply piping into a tee between
the circulator discharge and the boiler coil inlet.
4. Connect the boiler supply line to the combination return
and drain valve.
5. Connect hot water supply to top tank fitting.
6. Install 19mm (¾ in.), 150 psi Temperature and Pressure
Relief Valve into the tank as shown.
7. A check valve may be installed between the cold water
tee connection and the circulator. This will force the cold
water through the coil first.
NOTE: The check valve can often be noisy and cause
reduced supply pressures. For multiple storage tank sys-

tem, check valves must be installed to prevent the circulator
from pumping hot water into another tank and overheating
it.
8. The use of a pressure regulator is optional, but recom-
mended when the cold supply pressure is over 80 psi.
Reducing the inlet pressure to 45-60 psi will reduce
probability of relief valve discharge by thermal expan-
sion.
9. The water utility supply meter may contain a check
valve, back-flow preventer or water pressure reducing
valve. This will create a closed water system. During the
heating cycle, the water expands creating a pressure
build-up in the water system. A Temperature and
Pressure (T&P) Relief Valve must be installed (150 psi
maximum pressure). See preceding section. If the T&P
valve discharges periodically, this may be due to ther-
mal expansion in a closed system. To prevent this con-
dition and to reduce the possible build up of lime on the
Temperature and Pressure Relief Valve seat, either one
of the following installations is required;
i) Install a 125 psi pressure relief valve in the cold water
supply line. Make sure that the discharge of this valve is
protected from freezing and directed to an open drain.
ii) Install an expansion tank on the cold water supply
line.
10. A vacuum relief valve may be installed to provide vent-
ing of a closed system. Check local code requirements.
Electrical Wiring
Electrical wiring must be in accordance with local codes; or
in the absence of local codes with the National Electrical
code ANSI/NFPA 70 or The Canadian Electrical Code, as
applicable.
1. Supply 110/120 volt, 60Hz power, to the junction box
located at the top of the tank.
2. Connect the circulator pump in series with the thermo-
stat as shown in Figure 4.
3. A ground wire must be supplied from the ground con-
nection at the service panel to the ground screw at the
junction box.
4. The thermostat is rated for a maximum inductive current
of 7 FLA at 120 VAC. Do not exceed this rating for the
circuit.
5. Do not install or connect electrical heating elements to
this tank.
Filling
NOTE: When filling, avoid water leakage. Do not allow the
insulation of the tank to get wet as water can cause electri-
cal malfunction or reduce the effectiveness of the insulation.
1. To insure complete filling of the tank, allow air to exit by
opening a hot water faucet that is served by the tank
and is some distance away from the heater.
2. Ensure the storage tank drain valve is closed.
3. Open the cold water supply valve and fill the tank and
piping system with water. When an uninterrupted
stream of water, without apparent air bubbles, flows
from the open hot water faucet, the system is full.
4. Close the open hot water faucet. Check the system for
leaks, repair as necessary and retest.
5. Connect a hose to the drain valve and route to a suit-
able 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 dis-
connect hose.
Temperature Regulation
In order to reduce the risk of scald injury, the thermostat is
factory set to 60°C (140°F). The thermostat operates auto-
matically and can be adjusted to provide higher or lower
water temperature as needed. A mixing valve in connection
with a higher temperature setting should be used to reduce
risk of scald injury.

IV) OPERATION
1. Follow boiler or heat source installation and operating
instructions.
2. Fill the tank (see “FILLING” section).
3. The boiler or water heating source should be set to pro-
vide at least 11°C (20°F) higher water temperature than
the temperature setting of the storage tank
4. Turn power on, check for proper operation of boiler and
storage tank.
Temperature Adjustment
The National Plumbing code requires that the temperature
of residential electric service water heaters be set at 60°C
(140°F). The maximum outlet temperature of some bath fix-
tures must be tempered to 49°C (120°F) to reduce risk of
scalding. Higher temperatures increase the risk of scalding.
If water temperature adjustment is required:
1. Turn "OFF" the electrical supply to the tank.
2. Remove lower access door.
3. Turn back insulation.
4. Adjust thermostat to water temperature desired.
5. Replace insulation and access door.
6. Turn "ON" the electrical supply to the tank.
V) MAINTENANCE
T&P Valve Check
Do not attempt to operate this storage tank with the cold
water inlet valve closed. The Temperature and Pressure
Relief Valve must be manually operated at least once a
year. This involves opening the valve to check that it is flow-
ing freely and that there are no blockages. WARNING!
WATER MAY BE HOT and water flow can be forceful.
Caution should be taken to ensure that:
1. No one is in front of or around the outlet of the T&P
valve discharge line.
2. The water manually discharged will not cause any bod-
ily injury or property damage. The water may be
extremely hot.
While standing clear of the outlet (discharge water may be
hot), lift the lever and let it snap shut. The water should stop
immediately. If it fails to reset completely and continues to
release water, the valve is not functioning properly and must
be replaced immediately. Close the cold water supply valve,
drain the tank as directed in the “Draining and Flushing”
section, and replace the T&P valve with a new one. Failure
to install and maintain an approved T&P valve will release
the manufacturer from any claim that might result from
excessive temperature or pressure. In systems where the
relief valve discharges periodically, this may be due to ther-
mal expansion or to a thermostat that is operating at too
high a temperature. If you suspect a malfunctioning thermo-
stat, contact a qualified service technician for repairs.
CAUTION
The out-flowing water is hot. Avoid splashing the water on
yourself or on the surroundings where it may cause dam-
age.

Draining and Flushing
Some service work to be performed on the tank requires the
tank to be drained. It is also recommended that the tank be
drained and flushed every 6 months to remove any sedi-
ment and lime which may build up in the bottom of the tank
during operation. Such buildup can result in noisy operation.
To drain the tank:
1. Turn "OFF" the electrical supply to the tank.
2. Close the cold water supply valve.
3. Open a nearby hot water faucet served by the system.
4. Connect a hose to the drain valve and route it to an ade-
quate drain.
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.
5. Open the drain valve and allow all the water to drain
from the tank.
6. 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.
7. Perform any other servicing as required.
8. Close the drain valve, disconnect hose and refill the
tank (see “FILLING” section).
9. Turn "ON" the electrical supply to the tank.
Cathodic Protection
Your storage booster tank has been equipped with one or
more anodes that protect the tank from corrosion. Over
time, as the anode works, it slowly dissolves and must be
replaced. If the anode(s) is less than 10mm (3/8 in.) in diam-
eter, or has any of the inner steel core exposed, it must be
replaced. Depending on water conditions, an anode can last
from one to ten years. Many localities treat their water and
this can have a significant effect on the life of your heater.
Water conditioning, such as over-softening, can accelerate
the rate at which the anode(s) is consumed. Rapid depletion
can leave a heater unprotected causing a premature failure.
It is good practice to check the anode(s) annually to see if it
needs replacing. Operating a storage tank without an
actively working anode(s) will void the warranty. Failure to
maintain the anode may result in premature failure of the
storage tank due to corrosion and leaks.
Anode Maintenance
1. Turn "OFF" the electrical supply to the tank.
2. Close the cold water supply valve.
3. Open a nearby hot water faucet served by the system
to depressurize the system.
4. Connect a hose to the drain valve and drain 22 litres (6
gal.) as directed in the “Draining and Flushing” section.
NOTE: The anode(s) has been factory installed using a
power tool. It may be necessary for a second person to sta-
bilize the tank. A few sharp blows on the handle of the sock-
et wrench should loosen the anode nut. If an impact wrench
(power drive) is available, this is an easy way to remove an
anode.
6. Using a 1 1/16" socket, remove anode(s) and inspect it.
The surface may be rough, full of pits and crevices, but
this is normal. If it is less than approximately 10mm (3/8
in.) in diameter, or the inner steel core is exposed, the
anode(s) should be replaced.
7. Apply Teflon®tape or sealing compounds approved for
use with potable water, to the threads of the anode(s)
and install into the tank top.
8. Open the cold water supply valve and open a nearby
hot water faucet to purge air from the tank as directed
in the “Filling” section.
9. Check for leaks, repair as required, and re-test.
10. Turn "ON" the electrical supply to the tank.
