For your Safety (continued)
Carbon monoxide
The U.S. Consumer Product Safety
Commission strongly recommends the
installation of carbon monoxide
detectors in buildings in which
gas-burning equipment is installed.
Carbon monoxide (CO) is a colorless,
odorless gas, which may be produced
during incomplete combustion of fuel
and/or when the flame does not receive
an adequate supply of combustion air.
Carbon monoxide can cause severe
personal injury or loss of life.
Therefore, carbon monoxide detectors
that are in compliance with a nationally
recognized standard (e.g. ANSI/UL
2034-2002, CSA 6.19-01) should be
installed and maintained in buildings that
contain gas-burning equipment.
Note:
Viessmann does not test any detectors
and makes no representation regarding
any brand or type of detector.
For safe operation
We recommend that you frequently: - Check for debris which could obstruct
the flow of flue gases. The vent or chimney must not be blocked. A
blocked or partially blocked vent or chimney can cause flue gases to leak into the structure. Flue gases leaking
into the house can cause injury or death. Blocked or partially blocked
chimneys must have the blockage removed by a qualified heating contractor.
- Check pressure gage for correct system (water) pressure. Check for
water on the floor from the discharge pipe of the pressure relief valve or any other pipe, pipe joint, valve or air
vent. - Check for moisture, water, or
appearance of rust on the flue gas pipes, their joints as well as vent dampers, or side wall vent terminals
(if so equipped). - Ensure that nothing is obstructing the
flow of combustion and ventilation air and no chemicals, garbage, gasoline, combustible materials, flammable
vapors and liquids are stored (not even temporarily) in the vicinity of the
boiler. - Do not allow unsupervised children near the boiler.
Service/inspection of the boiler and the
system is recommended once a year. Maintenance, service and cleaning are specified in the Installation Instructions.
Before the heating season begins, it is
recommended that the boiler and burner be serviced by a qualified heating contractor. Service contracts may be
established through gas suppliers or other licensed contractors in your area.
5 4 1 4 5 5 4 v 1 .0
5 4 1 4 5 5 4 v 1 .0
As there are no user-serviceable parts
on the boiler, burner or control, the
end-user must not perform service
activities or adjustments of any kind on
system components. Failure to heed this
warning can cause property damage,
severe personal injury, or loss of life.
WARNING
Improper installation, adjustment,
service, or maintenance can cause flue
products to flow into living space. Flue
products contain poisonous carbon
monoxide gas which can cause nausea
or asphyxiation resulting in severe
personal injury or loss of life.
WARNING
Should overheating occur or the gas
supply fail to shut off, do not
disconnect the electrical supply to the
pump. Instead, shut off the gas supply
at a location external to the appliance.
CAUTION
The operator/ultimate owner is required
to have the heating boiler, burners, and
controls checked, as a minimum once
per year, by the original installer or by a
competent heating contractor familiar
with the equipment. Defects must be
corrected immediately.
WARNING
Do not use this boiler if any part has
been under water. Immediately call a
qualified heating contractor to inspect
the boiler and to replace any part of the
control system and any gas control
which has been under water.
CAUTION
Safety

For your Safety (continued)
Frozen water pipe hazard
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.
5 4 1 4 5 5 4 v 1 .0
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.
WARNING
