operation. Your heating contractor
should always perform the initial start-up
and explain the system. Any warranty is
null and void if these instructions are not
followed.
HWorking on the equipment
All personnel working on the equipment
or the heating system must have the
proper qualifications and hold all
necessary licenses.
Ensure main power to equipment,
heating system, and all external controls
have been deactivated.Close main gas
supply valve. Take precautions in all
instances to avoid accidental activation
of power during service work.

For your Safety (continued)
HCarbon 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.
HFor 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. A qualified heating contractor
must remove the blockage from
blocked or partially blocked chimneys.
- 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.
-Donot allow unsupervised children
near the boiler.
Service/inspection of the boiler and the
system is recommended once per year.
Maintenance, service and cleaning are
specified in the Installation and Service
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.
5581 532 v1.1
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

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...
HShut 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..
HHave someone check the building
frequently during cold weather and call a
qualified service agency if required.
Or...
HInstall a reliable remote temperature
sensor that will notify somebody of
freezing conditions within the home.
5581 532 v1.1
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.

Installation area conditions
HEnsure ambient temperatures are higher
than 32°F / 0°C and lower than
104°F / 40°C.
HPrevent the air from becoming

hydrocarbons (e.g. as contained in
paints solvents or cleaning fluids) and
excessive dust (e.g. through grinding or
polishing work).
Combustion air for the heating process,
and ventilation of the boiler room must
be free of corrosive contaminants. To
that end, any boiler must be installed in
an area that has no chemical exposure.
The list to the right indicates the main,
currently known sources.
HAvoid continuously high levels of
humidity (e.g. through frequent drying of
laundry).
HNever close existing ventilation
openings.
