Vitodens 100-W, WB1B Operating & User’s Information Safety

For your Safety (continued)

WARNING

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

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.

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. 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.

- Do not 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.

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

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

Vitodens 100-W, WB1B Operating & User’s Information

For your Safety (continued)

Safety

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.

Room dependent control:

Outdoor temperature sensor not connected

With no outdoor sensor installed, the “tr” dial will

provide a constant temperature set-point for the boiler

based on the dial position selected.

Setting the dial between 1 and 6 will provide a set-point

value of 81º F to 178º F (27º C to 81º C) respectively.

The dot between 4 and 5 represents the factory default

set-point value of 140º F (60º C).

Weather dependent control

Outdoor temperature sensor connected

With the outdoor sensor connected, the boiler will

automatically recognize the sensor and switch the set-

point dial operation from constant temperature calculated

to outdoor reset calculated.

Adjusting the “tr” dial will select the heating curve

corresponding with the heating curve chart. The set-

point will be calculated from the design boiler water

temperature associated with the heating curve selected,

and reset from the actual outdoor air temperature. Setting

the dial between 1 and 6 will select the corresponding

curve from the chart. The dot between 4 and 5 is the

factory default curve.

The display “tr” indicates when a heat request has

been made.

Note: Both the room dependent control and the outdoor

reset control strategies require a closed contact at

terminals RT to generate a call for heat to the

boiler.

Setting the dial to “0” places the boiler in freeze

protection mode regardless of the control option

selected or the contact position at RT.

Switching OFF

Turn the selector dial “tr” to “0”.

Note: If an external OpenTherm device is connected that

controls the boiler water temperature, it can no

longer be adjusted using the selector dial “tr”
