Supply And Packaging - ATTACK FD20 Instructions For Use Manual

The opening should be situated in the lower part of an outer wall, preferably opposite the com-
bustion gas discharge.
Flue connection
A flue should correspond to the following parameters:
• it should be from waterproof materials resistant to the temperature of smokes and conden-
sations,
• it should have sufficient mechanical resistance and a weak thermal conductivity,
• it should be hermetic in order to avoid cooling of the flue,
• it should be vertical and the terminal part should have a static aspirator which ensures an
efficient and constant discharge of the combustion product
• In order to avoid the air streams and a high pressure around the chimney pot to prevent the
upward force of the combustion gas, it is necessary the discharge opening needs to hang
above at least 0.4 m of any adjacent structure. (including the roof ridge) and the height of
the chimney itself was at least 8 meters
• The flue shouldn t have a diameter inferior to the boiler connection.For flues with square or
rectangular sections, the internal section should be higher than 10% compared to the boil-
er connection section.
The net section of the flue can be obtained from the following:

7 SUPPLY AND PACKAGING

Supply of the boiler consists of:
• cast iron body
• on the cast iron body there is a set of fire sticks and a bag with the documentation (instruc-
tion of use, the list of service companies, production label)
• inside the cast iron body there is an ash collector and 2 bags:
• The 1st bag includes: a screw with a bakelite end for manually adjusting the air con-
trol door, a contact spring and an M6 lever that will be attached to the draft control
door.
• The 2.bag contains:a thermomanometer, thermostatic draught regulator, 2 flanges
for the boiler, 2 flange packings, 8 screws with hexagonal head, 8 fan-shaped wash-
ers, return valve
• Boiler casing (sidewall right and left, top cover, front panel with the logo of the manufactur-
er, rear cover, protective bar and 3 selftapping screws) in a cardboard box.

S – section in cm
K – reduction coefficient (0,045 for wood, 0,030 for coal)
P – boiler's output in kcal/h
H – height of the chimney in meters measured from the flame axis at the
exhaust of the chimney in the atmosphere. For the dimensioning of the
flue you should consider the effective height of the chimney in meters
measured from the flame axis to the top, diminished in:
• 0,5 m for each direction changing of the connection tube between
boiler and flue,
• 1 m for each horizontal meter of the connection itself.
