Safety Warning (Flammable Vapours)
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-
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 (Scalding)
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. Such precautions must be followed when
this heater is operated in combination with dishwashing or
space heating applications.
