John Wood Power Vent (Non-ENERGY STAR qualified models) - Manual (Page 4)

II) SAFETY
This water heater is design-certified by CSA International as
a Category III, non-direct vented water heater that takes its
combustion 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 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:
"Natural Gas and Propane Installation Code" CAN/CSA-
B149.1 and "Canadian Electrical Code (CAN/CSA
C22.1), Part I" available from:
Canadian Standards Association,
5060 Spectrum Way,
Mississauga, Ontario, Canada
L4W 5N6
For Installations in the United States:
"National Fuel Gas Code" ANSI Z223.1 (NFPA 54) and
"National Electrical Code" (NFPA 70)" available from:
American National Standards Institute,
25 West 43rd Street,
New York, NY 10036
Massachusetts code requires this water heater to be
installed in accordance with Massachusetts Plumbing and
Fuel Gas Code 248 CMR Section 2.00 and 5.00.
Check your phone listings for the local authorities having
jurisdiction over your installation.
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 (see Figure 17). 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

over your installation.
• Failure to do so can result in death, explo-
sion or carbon monoxide poisoning.
