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.
Safety Warning (Carbon Monoxide)
Relief Valve Requirements (T&P)
All water heaters must be fitted with a proper temperature
and pressure relief valve. These valves must be certified as
meeting the requirements of the “Standard For Relief
Valves For Hot Water Supply Systems, ANSI
Z21.22/CSA 4.4”.
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 service
technician.
THESE CONDITIONS CAN RESULT IN UNSEEN INTER-
NAL DAMAGE and are not subject to warranty coverage.
DANGER
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.
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.
