Note:

The Vitodens 100-W boiler has passed the

zero inches vent clearance to combustibles

testing requirements provided by the boiler

Harmonized Standard ANSI Z21.13. CSA

4.9.2005 and therefore is listed for zero

clearance to combustibles when vented

with a single wall special venting system

(AL-29-4C material) or UL/ULC-listed CPVC

gas vent material. The zero inches vent

clearance to combustibles for the Vitodens

100-W boiler supercedes the clearance to

combustibles listing that appears on the

Technical Data/Heating Circuit Pumps

Waterside Flow boiler circuit)

The Vitodens 100-W is designed only for closed loop, forced

circulation hot water heating systems.

Pressure drop primary circuit) of Vitodens 100-W

Use standard friction loss method for pipe sizing.

Observe boiler maximum and minimum flow rate limitations. If system flow rate exceeds

boiler maximum flow rate (as stated on page 13) or if system flow rate is unknown, Viessmann strongly

recommends the installation of a low-loss header. See page 13 for low-loss header information.

Heating Circuit Pumps

Recommended heating pumps with Vitodens 100-W, WB1B 10-26, 10-35:

HGrundfos 15-58 (3-speed)

HTaco 00R

or equivalent

Refer to the graph above for the proper

waterside boiler friction loss calculations.

Pump selection must be based on accurate

system flow and pressure drop calculations

incl. DHW sizing).

A low-loss header must be used when the system flow

rate exceeds the maximum or falls below the minimum

flow rate of the Vitodens 100-W boiler. An alternative

method may be used, such as primary secondary piping

using closely spaced tees. A low-loss header offers

additional benefits not provided by a pair of closely

spaced tees. Viessmann strongly recommends and

prefers the use of a low-loss header over closely spaced

tees.

Please see page 13 for details.

IMPORTANT

DHW Production/Wall Mounting

Domestic Hot Water Production via DHW Storage Tank

Vitodens 100-W boilers can be used in

conjunction with the stand-alone DHW

storage tan s offered by Viessmann (a

separate DHW controller should be field

supplied). All Viessmann DHW storage

tan s sold in North America are available in

“Vitosilver” finish only.

Size and select the DHW storage tan based

on the forecast DHW consumption of the

building in question.

For further technical information on DHW

storage tan s, see the Vitocell-V Technical

Data Manuals.

Wall Mounting Information

The Vitodens 100-W (model WB1B 10-26

and 10-35) comes with a template, which

allows you to easily mar the location of the

screws for the mounting brac et and the

location of the flue gas pipe on the wall

(Viessmann coaxial PPS vent system only).

The connection to the heating circuits must

be made on site (installation fittings are

supplied in the Installation Fittings pac age

supplied with the boiler).
