MCZ Forma T50 [15/40] Connection to flue

4-FLUE

For stoves installed in studio ats, bedrooms and bathrooms (where allowed), it is mandatory to connect the combustion air outside. In

particular for sealed products the connection must be sealed in order not to compromise the overall sealed characteristic of the system.

DISTANCE (metres) The air inlet must be at a distance of:

1.5 m UNDER Windows, doors, smoke outlets, cavities, ....

1.5 m HORIZONTALLY Windows, doors, smoke outlets, cavities, ....

0.3 m ABOVE Windows, doors, smoke outlets, cavities, ....

1.5 m AWAY from smoke outlet

CONNECTION TO FLUE

The connection between the ue and the appliance must be via a smoke duct that conforms with EN 1856-2. To connect the replace to

the chimney ue or to a ceiling connection that is not coaxial to the unit’s smoke outlet, changes of direction must be made using open

bends no greater than 45° with respect to the vertical.

For stoves the connecting section to the ue must extend no more than 2 m horizontally, with a minimum slope of 3% and with a

maximum of 3 90° bends (accessible for inspection - do not count the T tting at the unit outlet).

The diameter of the smoke duct must be equal to or greater than that of the appliance outlet. A possible increase/reduction of the cross-

section is only allowed when the ue is connected (in particular the reduction must be conrmed by an adequate system size calculation).
