Solution:
The above formula applies, where:
e =0,035 standard value
Pi = Phid + 0,3 + Patm = 1 + 0.3 + 1 = 2.3 bar
Pf = Pseg + Patm = 3 + 1 = 4 bar
therefore:
V = (0.035 · 600) ÷ [1 -
(2.3 ÷ 4)] ≈ 49.41 l
You need to check the expansion vessel manufacturer's catalogue to chose a vessel
with a volume similar or higher than the calculated volume.

Fuel
Notice:The installation of this unit needs to meet the requirements of all applicable
standards and regulations
.
* This appliance uses dry firewood ONLY. It may not be used as an incinerator, nor
should use other materials such as coal, painted wood, varnishes, thinners, liquid
fuels, glues or plastics. Also avoid burning common combustible materials such as
cardboard and straw.
* The firewood should have a low water content (less than 20%) to ensure efficient
combustion, avoid creosote build-up in the smoke duct, and reduce oxidation of the
overall equipment;
* See Table 3 (on the next page), to get the list of some of the types of wood that can
be used in these units;
