I) INTRODUCTION
IMPORTANT:
This water heater must be installed strictly in accordance
with the instructions enclosed, and local electrical, fuel
and building codes. It is 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 leakage of the tank or relat-
ed water piping is directed to an adequate drain in such a
manner that it cannot damage the building, furniture, floor
covering, adjacent areas, lower floors of the structure or
other property subject to water damage. This is particular-
ly important if the water heater is installed in a multi-story
building, on finished flooring or carpeted surfaces. GSW
WILL NOT ASSUME ANY LIABILITY for damage caused
by water leaking from the water heater, pressure relief
valve, or related fittings. Select a location as centralized
within the piping system as possible. In any location
selected, it is recommended that a suitable drain pan be
installed under the water heater. This pan must limit the
water level to a MAXIMUM depth of 45mm (1 3/4 in.) and
have a diameter that is a minimum of 50mm (2 in.) greater
than the diameter of the water heater. Suitable piping shall
connect the drain pan to a properly operating floor drain.
When used with a fuel-fired heater, this drain pan must not
restrict combustion air flow.
