4-FLUE

MAINTENANCE

The ue must be kept clean, since the deposit of soot or unburned oils reduces the cross-section reducing the draft, thus compromising

the ecient operation of the product and, if large build-ups accumulate, they can catch re. The ue and chimney must be cleaned and

checked by a qualied chimney sweep at least once a year. Once the maintenance has been performed, request a written declaration that

the device is safe.

Failure to clean the system jeopardises the safety.

CHIMNEY

The chimney is a crucial element for the heating appliance to work properly: we recommend a wind proof chimney (A), see Figure 7.

The area of the opening for smoke

extraction must be at least double the

cross-section of the smoke duct/ue

system, and arranged so that smoke

extraction is ensured even in strong

wind. The chimney must prevent rain,

snow or animals from entering the

chimney. The height of outow into

the atmosphere must be beyond the

reux zone created by the shape of the

roof or any obstacles near the outlet

(see Figures 2-3-4-5-6).
