SAFETY

This water heater is design-certifi ed by CSA International as
a Category III, water heater that takes its combustion and
dilution 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 manual,
the water heater must be installed in accordance with
provincial codes and the latest edition of "Natural Gas and
Propane Installation Code" CSA-B149.1.

Safety Warning (Flammable Vapours)

WARNING
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., fl ue gases), in
using fuel-burning appliances such as water heaters. Areas
that may not be suitable for water heater installation include
those where fl ammable liquids, gasoline, solvents, adhesives
etc. are stored. Also not suitable are areas where engine-
driven equipment is stored, operated or repaired. Flammable
vapour products should not be stored or used near the water
heater or air intake. Due to the nature of air movement,
fl ammable vapours can be carried some distance from the
point of storage. Although the safety system is designed to
reduce the risk of fl ammable vapour related fi res, the gas-
fi red water heater igniter or burner fl ame can ignite these
vapours causing a fl ashback, fi re or explosion, which may
result in severe property damage, serious personal injury or
death. If fl ammable liquids or vapours have spilled or leaked
in the area of the water heater, leave the area immediately
and call the fi re department from a neighbor's home. Do not
attempt to clean the spill until all ignition sources have been
extinguished.
Flammable Vapours

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
(see Figures 11 & 12). Such precautions must be followed
when this heater is operated in combination with dishwashing
or space heating applications.

Safety Warning (Carbon Monoxide)

Breathing Hazard - Carbon Monoxide Gas
• Install vent system in accordance with codes.
• Do not operate water heater if flood damaged.
• For operation above 10,100' (3,079 m), a high
• Do not operate if soot buildup is present.
• Do not obstruct water heater air intake with
• Do not obstruct blower air intake.
• Do not place chemical vapor emitting products
• Gas and carbon monoxide detectors are
• No vent damper installation is compatible with
Breathing carbon monoxide can cause brain damage or death.
Always read and understand instruction manual.
As with all fuel burning equipment, this heater requires an
adequate supply of air for combustion. An insuffi cient air
supply can result in poor combustion or the re-circulation
of the fl ue gases. Such a condition may cause soot build-
up and present a fi re hazard. Flow reversal of fl ue gases
may 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 AIR IS NOT
RESTRICTED.
