1. General Characteristics

The V F boiler is set in the Factory to operate
on Natural Gas Group H with a supply pressure of 20mBar.

F

or higher gas pressure up to 300mBar, a filter and

a pressure regulator must precede the V

2. Boiler installation

Installation and maintenance of the installation shoukd be carried by a qualified
engineer according to the recommendations of the relevant codes of practice
and of the boiler manufacturer
The boiler must be installed in an appropriately ventilated compartment

…………………………………………………………….

3. Running the boiler

The boiler must be supplied with G20 natural gas

to bring the boiler into service

1. switch on the electrical supply

2. use the controls to set up a heating demand

3. when the boiler fires, check the gas line for soundness

and measure the combustion efficiency using
a flue gas analyser

4. Set up the controls to the programme required

by the Client

breaking any Factory equipment seals

invalidates the Boiler guarantee

4. Switching the boiler off

1. switch off the electricity supply

2. close the gas supply

5. Maintenance of the boiler

It is essential to service the boiler every year
Be ensure to employ a qualified engineer

6. Frost protection

If the boiler plant is not in use and there
is a risk of freezing, then anti-freeze should be
introduced to the system

In addition the boiler can be drained as follows

• switch off the electricity supply

• close the gas supply valve

• close the heating system isolating valve

• use the safety valve to release water pressure in the boiler

• release the automatic air vent to allow air to enter the boiler

• open the boiler drain valve to release

water from the boiler
