Vitocrossal 200, CM2-400, -500, -620 and 620 TX Operating Safety

For your Safety (continued)

Working 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.

Combustion air and ventilation openings

Ensure that combustion air openings and ventilation

air openings in the mechanical room are open.

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.

Dangerous conditions

- Deactivate main power immediately

- Close gas supply valve

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.

WARNING

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.

IMPORTANT

Keep all literature in a safe place at the installation site.

Contact Viessmann for additional copies.

For your Safety (continued)

Safety

WARNING

The boiler must not be located in areas or rooms

where chemicals are stored, or aggressive vapors

from (i.e. bleach, hair spray, methyl chloride, carbon

tetrachloride or perchloroethylene) or high dust levels

or humidity levels are present. Heat exchanger

corrosion might occur and reduce the lifetime of the

boiler significantly. If above criteria are not properly

observed and boiler damage results, any warranty on

the complete boiler and related components will be

null and void.

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

As there are no user-serviceable parts on the boiler,

burners or control, the end-user must not perform

service activities of any kind on system components.

Failure to heed this warning can cause property

damage, severe personal injury, or loss of life.

WARNING

Do not use this boiler if any part has been under, or

exposed to 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, or exposed to, water.

Maintenance and cleaning

Regular inspection and service by a qualified heating

contractor is important to the performance of the

Viessmann CM2 boilers. Neglected maintenance

impacts on warranty; regular inspection ensures

qualified heating contractor.

Regular maintenance and service

The entire heating system must be cleaned and

serviced on a regular basis by a qualified heating

contractor or service agency to ensure reliable,

energy-efficient, and environmentally friendly

operation.

The build-up of soot on the heat exchanger raises

the flue gas temperature and reduces efficiency.

installed) should be serviced within two years (at

most) of the installation date, and regularly thereafter.

For an overview of scheduled service procedures,

please see section entitled “Service Schedule” on

page 10 of this manual.

The owner or dedicated personnel should perform

the checks outlined in the Service Schedule to ensure

proper operation of the heating system.
