*5 Measured flue gas temperature with a combustion air temperature of 68°F (20°C).
*6 Based on maximum input rate.
*7 Requires 1 inch (25 mm) tubing. See the Installation Instructions of the Vitodens 200-W, B2HB for details.
*8 For side wall vent installations (coaxial system):
Do not exceed max. equivalent length specified in the Installation Instructions of the Vitodens 200-W, B2HB Venting System.
Do not attempt to common-vent Vitodens 200-W with any other appliance. Side wall co-axial vent installation must include Viessmann protective screen!
For details refer to the Installation Instructions for the Vitodens 200-W, B2HB Venting System.
For information regarding other Viessmann System Technology componentry, please reference documentation of respective product.
Note: For high altitude installation at 10,000 ft. the input for model B2HB 19 to 35 will have an altitude de-ration of 21%.

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.

Waterside Flow
Vitodens 200-W, B2HB 19 to 35 Technical Data
Waterside Flow (primary circuit)
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.
Supply head pressure (water)
Flow rate
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 ρt 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.
Before using the following pumps for a DHW tank application, find out the proper pressure drop through the tank, the required temperature difference through the coil and system piping head loss of the domestic hot water.
IMPORTANT
Pump selection must be based on accurate system flow and pressure drop calculations (includes DHW sizing).

Vitodens 200-W boilers can be used in conjunction with the stand-alone DHW storage tanks offered by Viessmann.
All Viessmann DHW storage tanks sold in North America are available in “Vitosilver” finish only.
Size and select the DHW storage tank based on the forecasted DHW consumption of the building in question. For further technical information on DHW storage tanks, see the Vitocell-V Technical Data Manuals.
For the connection of a stand-alone DHW tank, installation fittings (field supplied), an external circulating pump for DHW production (field supplied) and a DHW temperature sensor (optional equipment, see Viessmann Price List for order information) are required.

DHW Recirculation |
|
|
Domestic Hot Water Recirculation |
|
Vitocell-V stand-alone DHW storage tank |
DHW recirculation lines increase the level of comfort and |
|
convenience of the domestic hot water supply and reduce |
|
water consumption. |
|
These advantages directly derive from the immediate |
|
availability of domestic hot water at all draw points. |
|
Poor insulation of the DHW recirculation line, however, |
|
can result in considerable heat loss. Viessmann therefore |
|
recommends that effective insulation be provided and |
|
used for DHW recirculation lines of 23 ft. (7 m) in length |
|
or longer. |
