II Safety, For Installations in Canada

II) SAFETY

This water heater is design-certified by CSA International as a Category III, non-direct vented water heater that takes its combustion air either from the installation area or from air ducted to the unit from the outside.

In addition to the installation instructions found in this man- ual, the water heater must be installed in accordance with all local and provincial or state codes or, in the absence of such, with the latest editions of the following specifications.

lar products, should not be stored or used near the water heater or air intake. Due to the nature of air movement, flammable vapours can be carried some distance from the point of storage. The gas-fired water heater igniter or burn- er flame can ignite these vapours causing a flashback, fire or explosion, which may result in severe property damage, serious personal injury or death. If flammable liquids or vapours have spilled or leaked in the area of the water heater, leave the area immediately and call the fire depart- ment from a neighbor's home. Do not attempt to clean the spill until all ignition sources have been extinguished.

Safety Warning (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 of property damage, personal injury or death from the by-products of combustion (e.g., flue gases), 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, adhe- sives etc. are stored, or where engine-driven equipment or vehicles are stored, operated or repaired. These, and simi-

Safety Warning (Scalding)

DANGER

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 when water temperatures exceed 52°C (125°F). Use tempering valves, also known as mixing valves, in the hot-water system to reduce the risk of scalding at point-of-use such as lavatories, sinks and bathing facilities (see Figure 17). Such precautions must be followed when this heater is operated in combination with dishwashing or space heating applications.

Safety Warning (Carbon Monoxide)

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.

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 flue gases. Such a condition can cause soot build-up and present a fire hazard. Flow reversal of flue gases can cause an increase of carbon monoxide inside of the dwelling that could result in serious bodily harm or death from asphyxiation.

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