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 spreads 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 certified
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
accordance 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
corresponds to the power values obtained with propane gas.
•
Combustion testing
To limit consumption and avoid serious trouble, adjust combustion
by using the appropriate instruments. It is absolutely essential
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.
