1) The freeze prevention kit is designed to provide protection
for the water heater down to approximately 5°F for short
term conditions only. It will not protect the appliance in
areas where the temperature is routinely expected to be
below freezing.
- The freeze prevention kit will not protect plumbing outside the
appliance from freezing. Precautions should be taken.
