II) SAFETY

In addition to the installation instructions found in this man-
ual, the water heater must be installed in accordance with all
local and provincial or state codes or, in the absence of
such, with the latest editions of the following specifications.

For Installations in Canada:

“Installation Code for Oil-Burning Equipment (CSA
B139-04)”

and

“Canadian Electrical Code Part 1 (C22.1)”

available from:

Canadian Standards Association,
5060 Spectrum Way,
Mississauga, Ontario, Canada
L4W 5N6

For Installations in the United States:

“Standard for the Installation of Oil-Burning Equipment
(NFPA 31)”

and

“National Electrical Code (NFPA 70)” 

available from:

American National Standards Institute,
25 West 43rd Street,
New York, NY 10036

Check your phone listings for the local authorities having
jurisdiction over your installation.

Important:

Installation and service of an oil fired water

heater and burner must be performed by a qualified Oil-
Burner Technician to comply with local and provincial or
state codes applicable to this type of equipment. All supply
equipment, installation, approvals, permits, inspections, etc.
are the responsibility of the owner of this water heater.
Consult your local authorities for regulations specific to your
area.

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, flam-
mable 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)

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)

As with all fuel burning equipment, this heater requires an
adequate supply of air for combustion and ventilation. An
insufficient air supply can result in poor combustion or the
re-circulation of the flue gases. Such a condition can cause
soot build-up and present a fire hazard. Flow reversal of flue
gases can 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 AND VENTI-
LATION AIR IS NOT RESTRICTED.

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.

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.
