Note:The Vitodens boiler has passed the zero inches

vent clearance to combustibles testing requirements

dictated by the Harmonized Standard ANSI Z21.13.

CSA 4.9.2000 and therefore is listed for zero

clearance to combustibles when vented with a

single wall special venting system (AL-29-4C

material). The zero inches vent clearance to

combustibles for the Vitodens boiler supercedes

the clearance to combustibles listing that appears

on the special venting system label.

Typical System Flow Rates

Waterside Flow

Waterside Flow (primary circuit)

Boiler maximum flow rate 6.2 GPM (1400 L/h)

The Vitodens 200-W, B2HB is designed for closed loop,

forced circulation hot water heating systems only. 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 above), falls below the minimum flow rate

or if system flow rate is unknown, Viessmann strongly

recommends the installation of a low-loss header.

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 therefore

strongly recommends and prefers the use of a low-loss

header over closely spaced tees. See pages 25 and 26

for low-loss header information. Once the low-loss header

is connected, the built-in low-loss header logic of the

Vitodens 200-W boiler ensures the required rt across the

system through the sensory communication between the

low-loss header and the boiler.

Heating Circuit / Boiler Pumps

Viessmann offers a variety of Grundfos heating circuit/

boiler pumps which meet typical Vitodens system

installation requirements (see “Heating circuit pump

(field supplied)” or “Boiler pump (field supplied)” in the

Installation Examples starting on page 28). See tables

below for recommended pumps. Refer to the graph

on page 8 for the proper waterside boiler friction loss

calculations. The following pumps have been selected

based on boiler heat exchanger head loss and boiler piping

to a low-loss header.

IMPORTANT

Pump selection must be based on accurate system flow

and pressure drop calculations (includes DHW sizing).

tank, the required temperature difference through the coil

and system piping head loss of the domestic hot water.
