INSTALLATION

BOILER ROOM

Important

•Keep vents free at all times.

•Do not store inflammable products in the boiler room.

•Do not store corrosive products near the boiler, such as paints, solvents, chlorine, salt, soap and other cleaning products.

•If you smell gas, do not switch on the light or light a flame. Turn off the mains gas tap at the meter and inform the appropriate services immediately.

Access

The boiler room must be large enough to allow good access to the boiler. The following minimum distances are required around the boiler:

- front	500 mm
- side	100 mm
- behind	150 mm
- above	350 mm

Ventilation

The boiler room must have both low- and high-level ventilation, in accordance with the local standards and provisions force.

The table below gives an example conforming to the Belgian standards.

Ventilation		201
Min. fresh air requirement	m3/h	436
Bottom	dm2	2.45

Note:

Regulations vary from country to country therefore the table above is intended only as a guide.

Due to the high efficiency of our boilers, the flue gasses exit at low temperature. Accordingly, there is risk that the flue gasses could condense, which could damage the chimney. In order to avoid this risk, it is strongly recommended that the chimney be lined.

Connecting the boiler to an air vent type: C

•C53: parallel connection

total loss of pressure (air intake + flue-gas discharge) may not exceed 250 Pa. See the table below showing the pressure drops for the various components.

A condensation drain outlet must be fitted close to the boiler to prevent condensation products from the chimney running into the boiler.

To avoid condensation water running out of the terminal, all horizontal flue runs must fall back towards the boiler.

Top dm2 7.30

Other countries should refer to their own standards.

Base

The base on which the boiler rests must be made of non-combustible materials.

CHIMNEY CONNECTIONS

IMPORTANT

Boilers must be installed by an approved heating engineer, in accordance with the prevailing local standards and regulations.

The duct size may not be smaller than the boiler outlet duct.

Typical boiler connection: B23

The boiler is connected to the chimney by a metal pipe rising at an angle from the boiler to the chimney.

A flue disconnection piece is required.

This must be easy to remove to give access to the flue pipes when servicing the boiler.

Chimney / minimum flue diameter		201
E = 5 m Ø F min.	mm	350
E = 10 m Ø F min.	mm	300
E = 15 m Ø F min.	mm	270

	Air	Flue gas
	Ø 100 mm	Ø 250 mm
Pipe, L. 1000mm	18.0	1.0
90° bend	70.0	3.0
45° bend	28.0	-
Condensates trap	-	5.0
Terminal	50.0	3.0

When connecting the flue gas outlet to an existing chimney, do not take into account the pressure drop on the “flue gas side”.
