Working on the equipment

The installation, adjustment, service,

and maintenance of this boiler must be

performed by a licensed professional

heating contractor who is qualified and

experienced in the installation, service,

and maintenance of hot water boilers

There are no user serviceable parts on

the boiler, burners, or control

Ensure main power supply to

equipment, the heating system, and all

external controls has been deactivated

Close main gas supply valve Take

precautions in all instances to avoid

accidental activation of power during

service work

The completeness and functionality of

field supplied electrical controls and

components must be verified by the

heating contractor. This includes low

water cut-offs, flow switches (if used),

staging controls, pumps, motorized

valves, air vents, thermostats, etc.

in closed loop, forced circulation hot water heating circuits An external controller

is required for DHW production

The Vitodens 100-W comes factory set for operation with natural gas. Propane

conversion kit is included with each boiler

Boiler model must be selected based on an accurate heat loss calculation of the

building Ensure boiler model is compatible with connected radiation

Vitodens 100 boilers are factory tested and calibrated Further gas valve

adjustments are typically not required during field start-up

General Information

Mechanical Room

During the early stages of new home design, we recommend that proper

consideration be given to constructing a separate mechanical room dedicated to

gas- or oil-fired equipment including domestic hot water storage tanks

The boiler must be located in a heated indoor space, near a floor drain, and as

close as possible to the wall

Whenever possible, install boiler near an outside wall so that it is easy to duct the

venting system to the boiler

Locate boiler on walls capable of supporting the weight of the boiler filled with

water (see section entitled “Technical Data” on page 75 for information required

for total boiler weight calculation) Ensure that boiler location does not interfere

with proper circulation of combustion and ventilation air of other fuel burning

equipment (if applicable) within the mechanical room

The maximum room temperature of the mechanical room where the boiler is

located must not exceed 104°F/40°C

Boiler operation in marine environments

(damp, salty coastal areas):

The service life of the boiler’s exposed

metallic surfaces, such as the casing

and fan housing, is directly influenced

by proximity to damp and salty marine

environments In such areas, higher

concentration levels of chlorides from

sea spray, coupled with relative

humidity, can lead to degradation of

the exposed metallic surfaces

mentioned above Therefore, it is

imperative that boilers installed in such

environments not be installed using

direct vent systems which draw

outdoor air for combustion Such

boilers must be installed using room air

dependent vent systems; i e using

room air for combustion The indoor air

will have a much lower relative

humidity and, hence, potential

corrosion will be minimized
