SPECIFICATIONS FOR PROPANE USE
• Operating costs approximate assessment;
- 1 m3 of liquid gas in gaseous stage has a lower heating
capacity, of nearly 25.6 kWh.
- To obtain 1 cu.m of gas, about 2 kg of liquid gas are needed,
i.e. about 4 litres of liquid gas.
• This reveals that use of liquid gas (L.P.G.) yields approximately
the following equivalence: 25.6 kWh = 1 m3 (in gaseous phase)
= 2 kg of L.P.G. (liquid) = 4 l L.P.G. (liquid) from which the ope-
rating cost can be assessed.
• Safety provisions
• Liquid propane gas (L.P.G.) in the gaseous form has a greater
specific weight than air (specific weight relative to air = 1.56 for
propane), which means it does not disperse in air like natural
gas, which has a lower specific weight than air (specific weight
of natural gas relative to air = 0.60), but precipitates and spre-
ads out at ground level (as if it were a liquid). Summing up the
concepts we deem most relevant for the use of LPG
• Liquefied petroleum gas (L.P.G.) burners and/or boilers may be
used only in premises located above ground level and certi-
fied toward free spaces. Installations using liquid gas are not
allowed in underground or semi-underground premises.
• Rooms where liquid gas is used must have ventilation inlets
without closing devices, located on external walls with a surface
of at least 1/15 of the room’s area and a minimum of 0.5 m2.
At least one third of the entire surface of these inlets must be
located in the lower part of the external wall, flush with the floor.
• |b| Implementation of the liquid propane gas plant to ensure cor-
rect funcioning and safety.|bb| Natural gasification, from cylin -
der units or tanks, can only be used for low power plants. Gas
supply capacity on the basis of tank size and minimum outdoor
temperature are shown in the table below, as an approximate
indication only.
• |b| Burner;|bb|
The burner must be ordered specifically for use with liquid gas (L.P.G.) so that it is equipped with gas valves of sufficient dimensions to ensure correct ignition and gradual adjustment. The valve sizing is foreseen for a supply pressure of approximately 300 mm W.C. You are recommended to check the burner gas pressure using a water column manometer.
DANGER / CAUTION
Minimum and maximum burner power (Kcal/h) is the one
with natural gas fuel. L.P.G. has greater heating capacity
than natural gas, which means that for a correct combu-
stion it requires a quantity of air proportionate to the heating
power produced.
• Combustion control
To limit consumption and avoid serious trouble, adjust com-
bustion by using the appropriate instruments. It is absolutely
essential to check that the percentage of carbon monoxide (CO)
does not exceed the maximum permitted value of 0,1 % (use a
combustion analyser or other similar instrument).
DANGER / CAUTION
The warranty does not cover burners burning liquid gas
(L.P.G.) in installations in which these measures have not
been taken.
