OPERATING PRINCIPLES

VG boilers have been designed to heat hot water and must be connected to a heating plant and/or
a domestic hot water plant within the limits of its performance and output.

They are hot wate
r boilers with a maximum outlet temperature of 90 °C and a maximum allowable
operation pressure of 3 bar gauge. Return water temperatures must not be lower than 60
°C.

These boilers are not suitable for use as a direct water heater. Where potable or sanitary hot water
is required, a matching indirect heat exchanger must be provided in the system.

These boilers are suitable for high quality wood (log) with water content between 15 % to 20%.

This boiler is suitable for use in open vented expansion vessel heating systems. The system must
have a matching expansion system. Be sure that open vented expansion vessel and pipes are protected
against frost and has no manual valves between boiler and expansion tank.

If you will use this boiler with a closed expansion system, serious precautions and additional
equipment must be provided according to local and international standards and directives. Overheating and
over pressure can cause very serious hazards.

This boiler is not a condensate type of boiler so be sure that boiler is not in condensation for long
periods.

Do not open the upper door immediately when the boiler is operating. Open the lever very slowly
and be sure that all the smoke generated in the upper chamber is sucked before the door lever is free from
the blockade.
