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 tanks offered by Viessmann (a separate DHW controller should be field supplied). 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 forecast DHW consumption of the building in question.
Condensate Connection/Neutralization Unit Condensate Connection Install the condensate drain pipe (Ø 7/8” / 22mm) with a suitable gradient (min. 2.5%). Discharge condensate from the boiler into the drainage system, either directly or (if required) via a neutralization unit (accessory). The condensate drain of the Vitodes 100-W boiler is equipped with a built-in siphon trap in order to keep flue gases from being discharged via the condensate drain.
Venting Options / Electrical Connection Vitodens 100-W Venting Options For an overview of venting options refer to the appendix starting on page 19. For detailed information refer to the Vitodens Venting System Installation Instructions. Electrical Connection Control Unit All electrical connections are made to the boiler’s integrated power pump module (120 VAC/60 Hz). Use disconnect means and power service switch as per local code requirements.
