Safety Warning (Flammable Vapours)
WARNING
Flammable Vapours FLAMMABLES
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 similar
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 stor-
age. The gas-fired water heater igniter or burner flame can
ignite these vapours causing a flashback, fire or explosion,
which may result in severe property damage, serious per-
sonal 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 department from a neigh-
bor’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 bath-
ing facilities. Such precautions must be followed when this
heater is operated in combination with dishwashing or space
heating applications.
