14 Installation Manual
Protecting the Water Heater from
Freezing
Caution
•To protect the water heater 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
connected directly from the collars on the top of the water
heater to the outdoors. This type of vent system minimizes
air movement within the water heater.
•Freezing damage usually occurs due to back-drafting
caused by negative pressure in the building. This is not a
manufacturing defect, and therefore, VST 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 water heater from freezing, follow these guidelines:
•Do not unplug the power supply cord, except for routine
maintenance. The water heater has a freeze protection function
that warms up the water heater when the temperature inside
the water heater becomes lower than 43°F (6°C). The freeze
protection function will operate regardless of whether or not
the front panel is turned on or off, as long as the power supply is
still connected.
•If the power or gas supply must be disconnected for an
extended period, drain the water heater.
•Protect and insulate all water pipes, including the condensate
trap drain line, from freezing.
•If the water heater will not be used for an extended period of
time, drain the water heater.
Notice
If you suspect that the water heater is frozen, contact an authorized
technician or licensed professional.
Maintenance Schedules
Caution
A qualified technician should inspect the water heater at the
beginning of every heating season and/or when there is a
problem.
Owner maintenance
Daily
•Check that the area where the water heater is installed is free of
combustible/flammable material and air-contaminants.
•Visually inspect the exterior of the water heater.
Monthly
•Inspect the condensate trap and the PVC fittings.
•Visually inspect the piping (water and gas) for leaks.
•Visually inspect the vent piping for signs of leakage and
blockage.
Every 6 months
•Inspect the piping (water and gas) for leaks.
•Inspect the vent piping for leakage and blockage.
•Test to make sure the pressure relief valve is operating properly.
•Be carefully to avoid contact with hot water coming out of the
pressure relief valve and to prevent water damage when you
operate the relief valve.
Hot water Cold water
Pressure relief valve
