In Earthquake Zones; Closet Installations; Floor Surfaces; Clearances And Accessibility - John Wood POWER VENTED GAS FIRED WATER HEATER Installation And Operating Instructions Manual

Select a location as centralized within the piping system as
possible. The heater should be located in an area where
leakage of the tank or connections will not result in damage to
the area adjacent to the water heater or to lower fl oors of the
structure (see "IMPORTANT" notice on the previous page).
Before installing this water heater, consideration and planning
must be given to the following details:
•
Proximity to walls and other objects (see "Clearance and
Accessibility").
•
Access to gas supply (see "Gas Supply").
•
Routing and support of the vent piping and termination
(see "Venting").
•
Position of water supply and placement of water piping
and floor drain (see "Water Supply").

In Earthquake Zones

The water heater must be braced, anchored, or strapped to
avoid moving during an earthquake. Contact local utilities for
code requirements in your area.

Closet Installations

The water heater may be installed in a closet with a door that
is connected to a bedroom or bathroom providing the units are
installed and vented per the manufacturer's instructions.

Floor Surfaces

If installing over carpeting, the carpeting must be protected
by a metal or wood panel beneath the water heater. The
protective panel must extend beyond the full width and depth
of the water heater by at least 76mm (3 in.) in each direction
or if in an alcove or closet installation, the entire fl oor must
be covered by the panel.

Figure 2 may be used as a reference guide to locate the
specifi c clearance locations. A minimum of 600mm (24 in.)
of front clearance and 100mm (4 in.) on each side should be
provided for inspection and service.

Gas Supply

Explosion Hazard
• Install a gas supply shut-off valve.
• Do not connect a natural gas water heater to
a L.P. gas supply.
• Do not connect a L.P. gas water heater to a
natural gas supply
• Failure to follow these instructions can result
in death, an explosion or carbon monoxide
poisoning.
Read the data plate to be sure the water heater is made
for the type of gas you will be using in your home. This
information will be found on the data plate located above the
gas control valve. If the information does not agree with the
type of gas available, do not install or attempt to start.
