Safety Warning (Flammable Vapours)

WARNING

FLAMMABLES

Flammable Vapours

FIRE AND EXPLOSION HAZARD

Can result in serious injury or death

Do not store or use gasoline or other flammable vapours and liquids in the vicinity of this or any other appliance. Storage of or use of gasoline or other flammable vapours or liquids in the vicinity of this or any other appliance can result in serious injury or death.

There is a risk in using fuel-burning appliances such as water heaters. Areas that may not be suitable for water heater installation include those where flammable liquids, gasoline, solvents, adhesives, etc., or engine-driven equip- ment or vehicles are stored, operated or repaired. Due to the nature of air movement, flammable vapors can be car- ried some distance from the point of storage. The gas-fired water heater igniter or main burner flame can ignite these vapors causing a flashback, fire or explosion which may result in serious personal injury or death, as well as severe property damage.

Safety Warning (Scalding)

DANGER

can cause soot build-up or present a fire hazard, and may result in serious bodily harm or death from asphyxiation.

MAKE SURE THE FLOW OF COMBUSTION AND VENTI- LATION AIR IS NOT RESTRICTED.

DANGER

Carbon Monoxide Warning

•Follow all vent system requirements by the local authorities having jurisdiction over your installation.

•Failure to do so can result in death, explo- sion or carbon monoxide poisoning.

Relief Valves (T&P)

All water heaters must be installed with a proper tempera- ture and pressure relief valve. These valves must be certi- fied as meeting the requirements of the “Standard for

Temperature, Pressure, Temperature and Pressure Relief and Vacuum Relief” CSA 4.4 in Canada. In the United States “Relief Valves and Automatic Gas Shut-Off Devices for Hot Water Supply Systems”, ANSI Z21.22 is applicable.

If this water heater has been exposed to flooding, freezing, fire or any unusual condition, do not put it into operation until it has been inspected and approved by a qualified profes- sional. THESE CONDITIONS CAN RESULT IN UNSEEN INTERNAL DAMAGE which is not subject to warranty cov- erage.

Backflow Prevention

Certain jurisdictions may require the installation of a back- flow device (e.g., check valve) in the water supply line. Such a device will require the use of a system expansion tank of adequate size to control the thermal expansion generated during the heating cycle. Consult your water supplier or local plumbing authority.

Important: The supply water meter may have a built-in check valve device. Contact your local water authority.

Hot water produced by this appliance can cause severe burns due to scalding. The hazard is increased for young children, the aged or the disabled where water tempera- tures exceed 52°C (125°F). Use tempering valves (see Figure 11), in the hot water system to reduce the risk of scalding at point-of-use such as lavatories, sinks and bathing facilities. Such precautions must be followed when this heater is operated in combination with dishwashing or space heating applications.

Safety Warning (Carbon Monoxide)

As with all fuel burning equipment, this heater requires an adequate supply of air for combustion and ventilation. An insufficient air supply can result in poor combustion or the re-circulation of the exhaust flue gases. Such a condition

CAUTION

Hydrogen gas can be produced in a hot water system served by this heater 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. If 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.
