Domestic Hot Water Production

To ensure optimum operation of your heating system
do the following:
H Keep the boiler and the boiler room clean and free
of dust and dirt.
H Ensure proper and adequate system pressure
by occasionally checking the pressure gage.
H Have a qualified heating contractor service and maintain
your heating system on a regular basis. See Service
Schedule starting on page 10 for details.
The boiler controls monitor the operation of your heating
system in conjunction with installed system controls
(if applicable) based upon indoor/outdoor control, setback
programming and other settings. Please refer to the
respective documentation of the boiler controls, or other
system controls, to make adjustments.
Deactivate main power switch and all additional switches
controlling additional pumps or controls, including main
switch for burner. Close all valves in the system.
IMPORTANT
Read the operating instructions supplied with the Vitotronic
control, as well as Operating Instructions of the gas burner
before deactivating or activating the heating system.
In case additional controls are installed in the boiler room,
e.g. control aquastats, mixing valves, controls etc., please
observe their respective operating instructions.
The Vitocrossal 300 boiler may be used to supply
domestic hot water heating by means of an indirect-fired
hot water storage tank. The appropriate connections
to the boiler must be made, as well as the correct size
circulating pump must be used. The control circuit to
provide domestic hot water is already provided within the
Vitotronic control.
