Important information about the boiler room

 

9

The boiler room should be well lit and the light switches 

should be located outside the room itself.

 

9

Place any gas detection devices at a height conforming to 

regulations in force.

 

9

Do not place devices like the water pump, the contactor, 

etc., in the boiler room.

 

9

Repair or replace as soon as possible any electric locks, ca-

bles, etc., that could cause short-circuits.

 

9

Before carrying out any welding in the boiler room, switch 

off the boiler and close the gas valve.

 

9

The boiler room should not contain any explosive, combus-

tible or inflammable material.

 

9

The boiler room air should not contain any explosive, com-

bustible or inflammable gas.

 

9

Children or non-technical persons should not be allowed in 

the boiler room, except for the person who is responsible for 

it. Keep a copy of the key for the boiler room in a safe place 

for emergencies.

 

9

It is possible to insulate the boiler room against noise and 

heat, also the position and the orientation of the boiler are 

important for its acoustic insulation.

 

9

Place the fuel tanks in another room surrounded by walls 

and with adequate natural ventilation.

 

9

Arrange for the creation of a branching of the water supply 

line near the boiler and a drainage system for draining the 

boiler water.

 

9

It is strongly recommended not to install extraction systems, 

air conditioning systems or other devices in the boiler room 

that, as a secondary effect, could cause the so-called "vac-

uum effect" and reduce the draught force of the boiler, with 

the main consequence of damaging the burner.

 

9

Make sure that the boiler room receives sufficient air either 

naturally or forced (using an aspirator).

 

9

To ensure the burner and the boiler work efficiently keep the 

boiler room clean and prevent the formation of humidity.

 

9

The boiler room should have the minimum dimensions 

specified.

 

9

Do not store inflammable material inside the room.

 

9

Do not touch the supply pipe fitting or other hot parts of the 

boiler when it is running.

 

9

Do not install the boiler on a rubber mat.

 

9

When using LPG or another liquid fuel, the boiler room, the 

fuel, the system components and the hydraulic pipes need 

to be in conformity with the parameters established by Eu-

ropean norms and by gas supplying companies. The com-

pany is not responsible for any faults or problems caused by 

the inadequate conditions of the boiler room, the hydraulic 

pipes and the other components of the system.

 

9

Follow the instructions of your local gas suppliers.
