John Wood® Safety Systems
Flammable Vapour Ignition Resistant (FVIR) technology you
can trust.
John Wood residential water heaters use one of three 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® and Flame SafeTM Safety Systems
and the Power Vent Safety System.
Flame Guard® Safety System Used on
John Wood Atmospheric Vent Water Heaters
The Flame Guard® Safety System is a recognized and proven technology used
on John Wood Atmospheric Vent 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.”
Flame SafeTM Safety System Used
on John Wood Direct Vent Water Heaters
Flame SafeTM technology - designed to protect the consumer against the
ignition of flammable vapours.
Power Vent Safety System
The Safety System used on John Wood Power Vent water heaters features a flammable
vapour sensor and air intake snorkel. This system not only shuts down the unit when
flammable vapours are detected in the area of the water heater but elevates the air
intake so that flammable vapours do not enter the combustion chamber and ignite
before the sensor shuts down the water heater.

Flow rate is determinded by temperature rise. To determine your temperature rise,
subtract the incoming water temperature from the set output temperature. All units
are factory set to 120ºF or 122ºF but can be changed.
Flow rates are based on default set temperatures.

Flow rate is determinded by temperature rise. To determine your temperature rise,
subtract the incoming water temperature from the set output temperature. All units
are factory set to 120ºF or 122ºF but can be changed.
Flow rates are based on default set temperatures.

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.

Temperatures
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 gallon of water weighs 8.33 lbs.
• 1 gallon of water has a volume of 231 cubic inches
• 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 contains 4.3 gallons
• 8.33 BTU will raise 1 gallon of water 1o F at 100% efficiency (electricity)

• 11 BTUs are required to raise 1 gallon of water 1o F at 70% efficiency (gas)
• 3,412 BTUs equal 1 kilowatt hour (KW)
• 1 KW 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 KW will raise 10.25 gallons of water 40o F at 100% efficiency
1 KW will raise 6.8 gallons of water 60o F at 100% efficiency
1 KW will raise 5.1 gallons of water 80o F at 100% efficiency
1 KW 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 temperature
H-C
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
120 – 50 = 70
= 79% of the shower is 120o hot water
This formula for mixing hot water is important when explaining a NOT ENOUGH
HOT WATER trouble call and the water heater is functioning properly.
