John Wood® Safety SystemsFlammable 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 Superflue Safety System.

Flame Guard® Safety System Used onJohn Wood Atmospheric Vent Water Heaters

The Flame Guard® Safety System is a recognized and proven technology used on John Wood used on 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 Usedon John Wood Direct Vent Water Heaters

Flame SafeTM technology - designed to protect the consumer against the ignition of flammable vapours.

Superflue® Safety System Used on John Wood Power Vent Water Heaters

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 vapour 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.

AppendicesReference 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).

Formula for mixing hot water

M-C H-C

WhereM=mixedwatertemperature;C=coldwatertemperature;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

This formula for mixing hot water is important when explaining a NOT ENOUGH HOT WATER trouble call and the water heater is functioning properly.

=79%oftheshoweris120o hot water

= Percent of hot water required to produce desired mixed temperature

= 23 gallons per hour

= 80o temp
