Maintenance is necessary; warn the Operator/
ultimate owner of the obligation to check the
appliance and maintain it in good working order.
•
Give all the instruction manuals to the Operator/
ultimate owner.
WARNING
Serious property damage and/or personal injury can
occur if the pipes are not protected from freezing,
resulting in the pipes bursting. The boiler may also
shut down. Turn off the water supply and drain the
water pipes or protect them from freezing when
leaving the home unattended for long periods of time
during very cold weather conditions.
The boiler is designed to provide a comfortable
and warm environment and is not designed for the
prevention of frozen water pipes. In case an unsafe
condition occurs, the boiler has been designed and
equipped with several safety devices that will shut
down the boiler and stop it from restarting.
If the boiler is dormant for an extended period of time
during cold winter weather, the water pipes may freeze
and burst which can result in extensive water damage
and lead to mold growth. A variety of molds can cause
serious health and respiratory problems. If water
damage should occur, immediately dry the affected
areas to avoid the possibility of mold growth.
If the building will be empty for an extended period of
time in cold winter conditions, then the following steps
should be taken:
•
Turn off the building’s water supply, drain the pipes
and add some antifreeze for potable water for the
toilet tanks and drain traps.
•
Open faucets where appropriate
•
Have the building monitored and checked during
cold winter weather and call a qualified service
technician if necessary.
•
Remote temperature sensors are available and can
be installed which will alert someone if freezing
conditions occur in the building.
