3 - Smoke valve register

Combustion is not always regular; as matter of fact both atmospheric conditions and outside temperature can inuence it by modifying

the depression in the stack. For this reason, all inserts are equipped with an adjustable smoke valve with automatic opening allowing an

optimal adjustment of the draught.

Through the lever located on the bottom left, it is possible to position the smoke valve correctly (all to the left = all open). Should the door

open independently from its position, the smoke valve opens automatically.

The adjustment of the registers necessary to reach the rated caloric yield is the following one:

5. FLUE

Essential requirements for a correct operation of the device:

• the internal section must be preferably circular;

• be thermally insulated and water-proof and produced with materials suitable to resist to heat, combustion products and

possible condensates;

• not be throttled and show a vertical arrangement with deviations not greater than 45°;

• if already used, it must be clean;

The minimum section must be 4 dm

(for example 25 x 25 cm) for devices with diameter greater than 200 mm.

The draught created by the ue must be sufcient, but not excessive.

A too big ue section can feature a too big volume to be heated and consequently cause difculties in the operation of the device; to avoid

this, tube the ue along its whole height. A too small section causes a decrease of the draught.

ATTENTION: as far as concern the realisation of the ue connection and ammable materials please follow the requirements provided by

UNI 10683 standard. The ue must be properly spaced from any ammable materials or fuels through a proper insulation or an air cavity.

It is FORBIDDEN to let plant piping or air feeding channels pass in the same ue. Moreover, it is forbidden to create movable or xed

• have internal section equivalent to that of the stack.

• have a useful output section twice as big as the ue internal one.

• be manufactured in such a way as to prevent the penetration of rain, snow, and any other foreign body in the ue.

• be easily checkable, for any possible maintenance and cleaning operation

5.2. CONNECTION TO THE FLUE

The connection to the stack must be performed with stiff pipes in steel comply with all current Standards and Regulations and to those

envisioned by the Law.

It is FORBIDDEN to use metallic pipes or pipes in asbestos cement since they jeopardize the safety of the tting itself, considering

that they are subject to tears or breaks resulting in leaks of smoke.

The exhaust pipe must be air-tight fastened to the stack and can have a maximum inclination of 45°; this to avoid excessive deposits of

The measurement has always to be carried out with hot device (rated thermal performance).
