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 Safe TM 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 Safe TM Safety System Used on John Wood Direct Vent Water Heaters Flame Safe TM 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. 3

Appendices 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. 56

Rise 3413 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).

My shower temperature is 105 o F, my water heater thermostat is set on 120 o F and the cold water inlet temperature is 50 o F. 105 50 = 55 120 50 = 70 = 79% of the shower is 120 o 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. 60
