WINTERIZATION
Freezing of the water heater and its plumbing components will result in severe damage that is
not covered by warranty. For this reason it is not advisable to use the standard unit (Part# 1GWH)
in the winter
without installing the Winter Use Device (See below for Winter Use Device
option).
At the start of the winter season or before traveling to a location where freezing conditions are
likely the unit must be winterized. The very small amount of water present in the heat exchanger
does not require the installation of a bypass kit.
Winterization can be accomplished using one of the two common methods of winterization used
for RV water systems:
•
Compressed Air Method:
Drain all water from the system opening one tap at a time
and using compressed air to purge all remaining water.
•
RV Anti-freeze Method:
Follow the recommendations of the Recreation Vehicle
manufacturer and fill the system with a non toxic anti-freeze. Make sure that the
antifreeze flows from each tap to complete the process.
