Pressure build-up in a water system
When the water heater operates, the heated water expands creating
a pressure build-up. This is a natural function and is one of the rea-
sons for installing a temperature and pressure-relief valve. If the cold
water supply line has a built-in water meter, check valve, or pres-
sure-reducing valve, a suitable expansion tank must be installed to
prevent pressure build-up or water hammer effect, otherwise the
warranty is void (see figure 2). An indication of pressure build-up is
frequent discharges of water from the relief valve. If the relief valve
discharges water on a continuous basis, it may indicate a malfunc-
tion of the relief valve, and a qualified service technician must be
called to have the system checked, and the problem corrected.

DANGER
WARNING
CAUTION
AVERTISSEMENT
ATTENTION
neveR operate the water heater unless it is completely filled with
water. Failure to follow this instruction can result in premature
failure of the water heater and its component parts that is not
covered by the warranty.
Check that all of the water piping connections have been made. To
fill the water heater:
1) Make sure that the water heater drain valve is closed by inserting
a flat-head screwdriver into the slot on the head of the drain valve
and turning the knob clockwise
.
2) Open the cold water supply manual shut-off valve. This valve
must remain open, as long as the water heater is in use. Never
operate the water heater with the cold water supply manual shut-
off valve closed.
3) To make sure the water heater is completely filled with water,
open hot water faucets to let the air out of the water heater and
plumbing system. Leave the faucets open until a constant flow of
water is obtained.
4) Check all of the plumbing connections to make sure there are no
leaks.
