Residential
GSW Safety Systems
Flammable Vapour Ignition Resistant
(FVIR) technology you can trust.
GSW Water Heating has developed two unique Flammable Vapour
Ignition Resistant (FVIR) Safety Systems that reduce the risk of
accidental fires caused by the ignition of flammable vapours from
products such as gasoline, paint thinner and solvents: the Flame
Guard® Safety System and the Superflue® Safety System.
Flame Guard® Safety System
The Flame Guard® Safety System is a recognized and proven
technology, exclusive to GSW and John Wood residential gas
water heaters. The award-winning Flame Guard® Safety
System protects the consumer by trapping burning vapours within the
water heater combustion chamber through the patented “Flame-Trap”.
As long as the vapours are present and within the flammability range,
they will continue to burn safely until they “burn themselves out”.
Superflue® Safety System
The Flammable Vapour Ignition Resistant (FVIR) Superflue® Safety
System is a cutting-edge design unique to GSW power vented
residential gas water heaters. The Superflue® Safety System features a
flammable vapour sensor that protects the consumer by detecting the
presence of flammable vapours in the atmosphere around the water
heater and disabling the unit to minimize the risk of ignition. It also
features a robust air intake snorkel that inhibits flammable vapours
from entering the combustion chamber and igniting.

Diaphragm pump tanks from 2 to 119 US gallons.
• Positive lock retention system ensures controlled compression
in the diaphragm connection, eliminating the loss of air or water
from the tank
• Interior epoxy coating permanently bonded
to the tank shell to provide the ultimate
protection on the water side of the tank
• Durable butyl diaphragm ensures long life
• Undercoated with zinc phosphate for the
highest corrosion resistance
• Welded steel base

The new John Wood® Signature Series has been specifically designed
for the needs of the pro installer. Our new gas models now deliver
lower profiles for easy installation and maintenance, as well as smaller
vent diameters and ultra-accurate dual electric thermostats for
precision and control. What’s more, our Signature Series electric
models are custom build-to-order to ensure your exact specifications
are met. All of our heaters offer advanced features such as TankSaver®
stainless steel inserts and glass-lined tanks for longer life.

Tankless
John Wood FlowThru® by Noritz
Tankless for professionals.
Residential Models
John Wood FlowThru® residential water heaters by Noritz are designed
to provide abundant hot water for the entire home. All residential
tankless water heaters are backed by a 10-year warranty.
Commercial Models
Commercial tankless water heaters use commercial grade materials,
such as a coated copper heat exchanger and 25% thicker piping
than the residential models, making John Wood FlowThru® commercial
water heaters unique. Up to 24 can be linked with a system controller
to provide abundant hot water for heavy industrial applications.
Direct Vent, Sealed Combustion Models
John Wood FlowThru® offers Direct Vent models for use in areas where
combustion air from indoors is not available, such as spas, hair salons,
or air tight spaces. John Wood FlowThru® Direct Vent models take air
from outside for combustion. The John Wood FlowThru® line includes
the only commercial Direct Vent unit on the market. This unit has a
coated copper heat exchanger and 25% thicker piping than residential
models to ensure years of service.
Quick-Connect
All John Wood FlowThru® commercial, direct vent and most residential
models are Quick-Connect compatible, allowing two units to be
installed in series, doubling water capacity when needed.
Accessories
GSW offers a full line of accessories making installation quicker and
easier, not to mention cleaner and more aesthetically pleasing. GSW is
the “one-stop shop,” supplying everything from tankless water heaters
to valves to stainless steel venting.

Reference Calculations and Conversions for Electricity
Ohm's Law
Ohm's Law defines the relationships between (P) power, (E) voltage, (I)
current, and (R) resistance. One ohm is the resistance value through which
one volt will maintain a current of one ampere.
( I ) Current is what flows on a wire or conductor like water flowing down a
river. Current flows from points of high voltage to points of low voltage on
the surface of a conductor. Current is measured in (A) amperes or amps.
( E ) Voltage is the difference in electrical potential between two points in a
circuit. It's the push or pressure behind current flow through a circuit, and
is measured in (V) volts.
( R ) Resistance determines how much current will flow through a
component. Resistors are used to control voltage and current levels. A very
high resistance allows a small amount of current to flow. A very low
resistance allows a large amount of current to flow. Resistance is
measured in ohms.
( P ) Power is the amount of current times the voltage level at a given point
measured in wattage or watts

To convert from degrees Centigrade (C) to degrees Fahrenheit (F)
multiply the number of degrees C by 9/5 (or 1.8) and add 32.
To convert from degrees Fahrenheit (F) to degrees Centigrade (C) first
subtract 32 from the number of degrees F then multiply the remainder
by 5/9 (or 0.556).

• 1 cubic foot of water weighs 62.38 lbs and contains 7.48 gallons
of water
• 100 feet of 3/4" copper pipe contains 2.5 gallons of water; 1" pipe

• 3,412 BTUs equal 1 kilowatt hour (Kwhr)
• 1 Kwhr will raise 410 gallons of water 1o F at 100% efficiency
• 1 BTU x 0.293 = watts
• 1 KW = 1000 watts
• 2.42 watts are required to raise 1 gallon of water 1o F
1 Kwhr will raise 10.25 gallons of water 40o F at 100% efficiency
1 Kwhr will raise 6.8 gallons of water 60o F at 100% efficiency
1 Kwhr will raise 5.1 gallons of water 80o F at 100% efficiency
1 Kwhr will raise 4.1 gallons of water 100o F at 100% efficiency
Formula for mixing hot water
M-C
= Percent of hot water required to produce desired mixed
H-C temperature
Where M = mixed water temperature; C = cold water temperature;
H = hot water temperature
For example: How much of a shower is hot water and how
much is cold water?
My shower temperature is 105o F, my water heater thermostat is
set on 120o F and the cold water inlet temperature is 50o F.
105 – 50 = 55 = 79% of the shower is 120o hot water
120 – 50 = 70
This formula for mixing hot water is important when explaining a NOT
ENOUGH HOT WATER trouble call and the water heater is functioning
properly.
