Ensure the max. length of the entire
balanced flue system is not exceeded.
The max. length is reduced by 1m when
using a further 87° bend or 2 x 45° bends.
Deduct 3m from the max. possible
standard concentric horizontal flue length
and add the standard plume kit max length
to give max. length of entire flue system.
ie. 6m - 3m +2m = 5m max.

Ventilation Requirements
Detailed recommendations for air supply
are given in BS 5440:2. Please see
additional notes below.
• It is not necessary to have a purpose
provided air vent in the room or internal
space in which the appliance is installed.
• If the boiler is to be installed in a
cupboard or compartment, no
permanent air vents are required for
cooling purposes in the cupboard or
compartment, however, it is essential
to ensure that the minimum clearances
stated (page 9) are maintained.

Hydraulic connections
Heating System
(typical system designs)
• The Vitodens 100-W is designed for
connection to sealed central heating
water systems only.
• A sealed system must only be filled by a
competent person.
Combination boiler
Note
The boiler incorporates an internal bypass
to ensure adequate water flow. Certain
thermostatic radiator valve manufacturers
may require that a bypass valve is fitted
in addition to the integral by pass.
Specifications as to the individual
requirements should be sought prior
to installation.
Filling Loop
This boiler is not fitted or supplied with a
filling loop. Any filling loop being fitted
should comply with the water supply
(water fittings) regulations 1999 Section
G24.1 and G24.2. A filling loop should be
fitted at some point to allow the CH system
to be filled.
