HEATER-HOT WATER
A. Th
e 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. Th
e 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. Th
e 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.. Th
e caustic chemicals will
damage the hot water heater aluminum parts. Re-plumb
the heat exchanger back aft er 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. Th
e water will vacate to the shower
sump pump and then overboard.
