HOT WATER
SYSTEM
________________
Your 453 MotorYacht is equipped with a 20
gallon water heater, which is operated by the
A/C electrical system. Cold water is supplied
to the water heater from the fresh water pump,
which is then heated for distribution when de-
sired. Similar to the water heater in your home,
there is always a continuous supply of water to
maintain a full tank at all times. The water heater
in your 453 Motor Yacht is a “high recovery”
model, meaning the cold water entering the tank
is heated very quickly to replace the hot water
as it is used. The water heater is located in the
ceiling above the forward head.
The access panel is shown below.
Operation of the water heater is as follows:
Be certain the water heater is full of wa-
ter. You can easily check this by turning ON a
hot water faucet. If water fl ows from the faucet,
the water heater is full.
If the water heater is not full
of water, damage to the heating elements may
result when electrical power is turned ON to
the unit.
Turn ON the water heater breaker switch,
which is located on the AC/DC electrical panel
(See AC/DC Electrical Panel Layout on Page
163, which illustrates the location of the water
heater breaker switch).
NOTE: The water heater will operate on AC
electrical current only. You must either plug in
your shore power cord or operate your generator
for the water heater to function.
Allow suffi cient time for the water heater
to heat its contained water before using (ap-
proximately 1/2 hour).
General maintenance of the Hot Water System
is as follows:
Inspect all water lines and their connec-
tions at regular intervals. Tighten connections as
needed. If the water lines appear worn or are not
fl exible, see your Silverton dealer for replace-
ment.
Manually operate the pressure relief
valve on the water heater at least once a year
(See photograph below, which illustrates the
location of the valve).
DO NOT operate the pressure
relief valve while the water heater contains hot
water. Serious burns or injury could result.
