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.
• 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.
• The rooms in which LPG is used must be fitted with adequate
ventilation slots on external walls without closing devices in ac-
cordance with the regulations in force.
• Performance of the LPG system to ensure correct and safe
operation.
Natural gasification, from a cylinder bank or tank, can be used only for systems having low power. The following table gives an approximate indication of the gas output capacity according to the tank size and minimum outdoor temperature.
DANGER / CAUTION
The burner's minimum and maximum output (kW) is rated
based on its use with methane gas which more or less cor-
responds to the power values obtained with propane gas.
• Combustion testing
To limit consumption and avoid serious trouble, adjust combu-
stion by using the appropriate instruments. It is absolutely essen-
tial to check that the percentage of carbon monoxide (CO) does
not exceed the maximum value permitted by the regulations in
force (use a combustion analyser).
DANGER / CAUTION
The warranty does not cover burners burning liquid gas
(L.P.G.) in installations in which these measures have not
been taken.
