Protecting The Boiler From Freezing; Maintenance Schedules - Vesta VRC-80 User Manual

Protecting the Boiler from
Freezing
• To protect the boiler from freezing, recommend the use
of a direct vent exhaust and intake system. Ensure that
the exhaust vent pipe and the air intake pipe are both
Caution
connected directly from the collars on the top of the boiler
to the outdoors. This type of vent system minimizes air
movement within the boiler.
• Freezing damage usually occurs due to back-drafting
caused by negative pressure in the building. This is not
a manufacturing defect, and therefore, VESTA.DS will
not warrant any damage due to freezing. The installer is
responsible for ensuring that there is sufficient make-up air
to avoid such a situation, and the owner is responsible for
ensuring protection against freezing.
To protect the boiler from freezing, follow these guidelines:
•
Do not unplug the power supply cord, except for
routinemaintenance. The boiler has a freeze protection
functionthat warms up the boiler. The freeze protection
functionwill operate regardless of whether or not the front
panel isturned on or off, as long as the power supply is still
connected.
•
If the power or gas supply must be disconnected for
anextended period, drain the boiler.
•
Protect and insulate all water pipes, including the
condensatetrap drain line, from freezing.
•
If the boiler will not be used for an extended period of
time,drain the boiler.
Notice
If you suspect that the boiler is frozen, contact an authorized technician
or licensed professional.
