If a cabinet is mounted above the stove, minimum clearance between the stove’s cooktop and the
cabinet should be at least 70 cm.
-
Combustible materials (e.g. wallpapers, door casings, doors, etc.) require a clearance to flue pipes of at
least 20 cm. This clearance can be reduced if flue pipes are thermally insulated and if the temperature
of surrounding objects does not exceed 80
°
C.
-
The stove should be placed in a horizontal position or with its back slightly raised (3-4 mm).
5. CONNECTING TO CHIMNEY
Inspect the unpacked stove and study the stove parts and accessories, and in particular, make sure that:
-
asbestos-free sealing wires, which ensure tight sealing and prevent uncontrolled entry of air, are fitted
in special ducts of the firebox door, ash pan, cleaning access plate and cooktop frame,
-
combustion regulator (thermostat) correctly opens and closes the thermostat damper (Fig. 1, Item 19),
by using the regulation knob (Fig. 1, Item 10),
-
grate holder (Fig. 1, Item 13) is properly fitted on its supports and that it is easily opened.
Place the chimney connection (collar), which is delivered together with the stove and placed inside the wood
box, and screw it on the outlet on the cooktop or on the side outlet. First remove the cover and use the same
screws to fasten the collar.
NOTE:
If your chimney is of unsatisfactory or dubious quality, we recommend that you attach the collar on the cooktop
outlet and not on the side outlet.
The stove will reach its nominal heating capacity if the draft in the chimney is 20 Pa. A chimney ensuring good
draft is the basis of proper functioning of the stove. The chimney not only affects the stove’s output, but also
the combustion quality. Chimney draft directly depends on the chimney’s cross-section, height, internal wall
roughness and the difference between the temperature of gas and external air. We recommend the following
chimney sizes that ensure good draft:

Having a properly operating chimney and observing other requirements with respect to the material
specified below, ensures flawless stove operation.
-
If chimney draft exceeds 20 Pa, install a damper inside the flue pipe.
-
Chimney connection should be vertically positioned.
-
Horizontal pieces of flue pipes over 0.5 m long should slope upwards by 10
°
toward the chimney.
-
Flue pipe connection, flue pipes and chimney may not taper.
-
All joints, including the chimney, must be well sealed and there must be no soot or dirt inside the flue
pipes.
-
Protect the chimney from the cold (thermally insulate the chimney). This specially refers to chimneys
made of metal sheets or chimneys built on exterior walls.
-
Flue pipes that are not thermally insulated and that are placed in a vertical position may not be over
1.25 m long.
Draft intensity is checked using a candle (Fig. 2).
