Frozen water pipe hazard

WARNING
Failure to protect against frozen pipes could result in
burst water pipes, serious property damage and/or
personal injury. Boiler may shut down. Do not leave
your home unattended for long periods of time during
freezing weather conditions without turning off the
water supply and draining water pipes or otherwise
protecting against the risk of frozen pipes.
Your heating boiler is designed to provide a warm and
comfortable living environment. It is NOT designed to
ensure against freezing of water pipes.
The boiler is equipped with several safety devices that are
designed to shut down the boiler and to prevent it from
restarting in the event of various unsafe conditions.
If your boiler remains off for an extended period of time
during cold weather, water pipes may freeze and burst,
resulting in extensive water damage and conditions in
which mold could grow. Certain molds are known to
cause respiratory problems, as well as to pose other
serious health risks. In case of water damage, immediate
measures should be taken to dry out affected areas as
quickly as possible to prevent mold from developing.
If your home will be unattended for an extended period
of time during cold weather, you should...
- Shut off the water supply to the building, drain the
water pipes and add an antifreeze for potable water
to drain traps and toilet tanks. Open faucets where
appropriate.
Or...
- Have someone check the building frequently during
cold weather and call a qualified service agency if
required.
Or...
- Install a reliable remote temperature sensor that will
notify somebody of freezing conditions within the
home.
