WATER WITH SINGLE-WALL / DOUBLE-WALL (con't)
WARNING: Make sure valve is piped to a
proper drain per instructions. Scalding
injury and/or water damage can occur
from either the manual lifting of the lever
or the normal operation of valve if it is
not piped to a proper drain. Insure that
the safety relief valve piping is of the
proper material and rating for the
temperature and pressure of the system
and that it is secured to prevent possible
injury. If valve fails to flow water or
reseat, consult the factory.
CAUTION: The relief valve is a primary
safety device.
3. The temperature limiting device and
thermostat sensors that extend into the
water in the tank may become coated
with scale, depending on the type of
water in your area. This coating will
affect the accuracy of the sensors and
can allow the water temperature to
exceed the desired limits. They should
be removed from the tank and inspected
at intervals. Remove scale if present.
CAUTION: On control systems using 120
volt external power, be certain switch
is off, and power disconnected to
avoid electrical shock before work is
performed on this heater.
Since PVI cannot control the use of the water heater, water conditions, or maintenance,
the warranty on the water heater does not cover poor performance, structural failure, or
leaking due to an excessive accumulation of scale.
