II) SAFETY

In addition to the installation instructions found in this manual,
the water heater must be installed in accordance with all local
and provincial codes or, in the absence of such, with the latest
editions of the following specifi cations.

Installation Codes

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., 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, adhesives
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 storage. A
water heater igniter or burner 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 department from a neighbor's home. Do not attempt to
clean the spill until all ignition sources have been extinguished.

Safety Warning (Scalding)

DANGER
HOT
HOT
BURN
Some people are more likely to be permanently injured by
hot water than others. These include the elderly, children,
the infirm and the physically/mentally disabled. Table 1
(published by U.S. Government Memorandum, 1978) shows
the approximate time-to-burn relationship for normal adult
skin. If anyone using hot water provided by the water heater
being installed fits into one of these groups or if there is a local
code or provincial law requiring a certain water temperature
at the point of use, then special precautions must be taken.
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.
