Note: 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.

3.2 Specifications (Technical data)
Approved in US/Canada
1) 4TWHVK3S vent kit is compatible with this appliance but requires the purchase
of an additional 12" piece of straight pipe to meet minimum vent length
requirements. The aluminum flex piping included with this kit is not permissible
for use with this appliance.
Bradford White is constantly improving its products,
therefore specifications are subject to change without
prior notice.
