Heater-Hot Water; High Water Alarm - Regal 3760 Owner's Manual

HEATER-HOT WATER

A. The most important maintenance factor with the hot
water heater is that it is winterized with Winterban (RV
anti-freeze) in colder climates. Use the water heater drain
valve to vacate water from the tank. The water will
automatically drain into the shower sump pump and then
will be sent overboard. Make sure the water heater breaker
is turned off before any winterization is started to prevent
the element from being burned out.
B. If the system is constantly being used in warmer
climates it is a good idea to periodically drain the hot
water valve for 30 seconds or so to eliminate any scale
that has built up inside the hot water heater. Turn the
breaker off just as a precaution.
C. The hot water heater and heat exchanger parts are
made of aluminum. If engine flushing is required by the
manufacturer be sure to disconnect the heat exchanger
from the system temporarily.. The caustic chemicals will
damage the hot water heater aluminum parts. Re-plumb
the heat exchanger back after engine flushing.
D. Test the T& P valve periodically to make sure it works
properly. Its purpose is to let off excess water vapor
(steam) if the thermostat should stick and a critical
temperature situation develops within the tank. Pull on
the valve to test it. The water will vacate to the shower
sump pump and then overboard.
