HEATER-HOT WATER
A. The most important maintenance factor with the hot
water heater is that it is winterized with Winterban (RV
anti-freeze; alcohol style) in freezing 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 as a
precaution. Re
fi
ll the hot water heater before activating
the breaker to prevent element burn out.
C. The hot water heater and heat exchanger parts are
made of aluminum. If engine
fl
ushing 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
fl
ushing.
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.
