Freezing of the water heater and its plumbing components will result in severe damage not
covered by warranty. For this reason it is advisable to follow the recommendation(s) below if
the unit is to be stored in a freezing environment or for long periods of time. 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.
• Anti-freeze method: Follow the recommendations of the Recreational Vehicle manufacturer
and fill the system with a non-toxic anti-freeze. Make sure that the anti-freeze flows from each
tap to complete the process.
If you wish to operate the water heater in potentially freezing conditions the
model GSWH-1M has a built in thermostat that will start the burner whenever the
temperature of the Heat Exchanger falls below 38ºF and will automatically shut off
when it senses a temperature in excess of 58 ºF.
To allow the WUD device to operate you must have sufficient LP Gas in the tank
and you must leave the unit powered with the ON / OFF switch in the ON position
at all times that freezing may occur. It will not protect the entire RV's plumbing
system. The RV must be designed for winter use/freezing conditions.
This water heater is equipped with a temperature and pressure relief valve that complies with
the standard for Relief Valves and Automatic Gas Shutoff Devices for Hot Water Systems, ANSI
Z21.22.
• Valve is not serviceable; if defective it must be replaced.
• Tampering with valve will result in scalding injury. Do not place a plug or
reducing coupling on outlet part of valve. If you use a discharge line allow
complete drainage for both valve and line.
• Tampering with valve will void the warranty.
THIS VALVE IS A SAFETY COMPONENT AND MUST NOT BE REMOVED FOR ANY REASON
OTHER THAN REPLACEMENT.
