John Wood Direct Vent Models No Longer in Production - Manual (Page 2)

I) INTRODUCTION
Thank you for purchasing this water heater. Properly
installed and maintained, it will provide years of trouble
free service. This manual gives instructions for the prop-
er installation, safe operation and maintenance of this
water heater. It is your responsibility to ensure that your
water heater is properly installed and cared for.
The warranty on this water heater is applicable only when
the water heater is installed and operated in accordance
with these instructions. The manufacturer of this water
heater will not be liable for any injury or property damage
resulting from failure to comply with these instructions.
Protect your warranty: Regularly maintain your water
heater as detailed in the service and maintenance sec-
tion of this manual.
II) INSTALLATION
This heater must be installed by a qualified, licensed gas
fitter and according to CSA B149 Natural Gas and
Propane Installation Code or ANSI Z223.1 National Fuel
Gas Code and/or local codes. If in doubt, consult your
local utility.
LOCATION
Generally, the location selected should be as close to the
wall as practical and as centralized with the piping sys-
tem as possible. Heater should be located in an area not
subject to freezing temperatures.
The water heater should be located so that the controls
and drain are easily accessible. The heater should be
located in an area where leakage of tank or connections
will not result in damage to the area adjacent to the water
heater or to the lower floors of the structure. When such
locations cannot be provided, it is recommended that a
suitable drain pan be installed under the heater. Such
pans should be a maximum of 38mm (1-1/2 in.) deep and
have a minimum length and width of at least 50mm (2 in.)
greater than the diameter of the water heater and should
be piped to an adequate drain.
Under no circumstances is the manufacturer to be held
liable for any water damage in connection with this water
heater.
CAUTION: When this water heater is installed directly on
carpeting, carpeting must be protected by a metal or
wood panel beneath the appliance extending beyond the
full width and depth of the appliance by at least 76mm (3
in.) in any direction, or if the appliance is installed in an
alcove or closet, the entire floor must be covered by the
panel. The panel must be strong enough to carry the
weight of the heater when full of water. Failure to heed
this warning may result in a fire hazard.
Minimum clearances between the heater and com-
bustible/non combustible materials are 25mm (1 in.) at
the sides and rear; 508mm (20 in.) from the top of water
heater and 25mm (1 in.) around the vent pipe. A minimum
of 915mm (3 ft.) of clearance is required at the front (con-
trol) side of the heater for service.
For a closet installation, the door at burner side should be
openable and a minimum of 102mm (4 in.) clearance is
needed. Water heater is certified for installation on a
combustible floor (see Figure 1).

WARNING
This water heater must be installed strictly in
accordance with the detailed instructions
enclosed and local building codes. It must be
installed with a proper pressure relief valve
which may release water in operation. It is also
possible that connections to the water heater,
or the water heater itself, may develop leaks. It
is therefore IMPERATIVE that the water heater
be installed so that any water is directed to an
adequate drain in such a way that it cannot
damage the building, furniture, carpeting or
other property subject to water damage. GSW
CANNOT BE HELD RESPONSIBLE for dam-
age caused by water from the water heater,
pressure relief valve, or related fittings where
adequate provision to drain such water has not
been made. Closets without drains and carpet-
ed areas are examples of unsuitable locations
for any water heater.
