CABINET HEATER
4.5 Gas Supply
General
The installation must comply with local laws and regulations, and the complete installation including the meter, where
fitted, must be purged and tested for soundness.
The gas supply must be adequately sized to carry a sufficient quantity of gas at the specified pressure at the heater
inlet whilst firing (see data tables in section 2).
The gas supply must be sized to supply the correct amount of gas to the heater under all load conditions.
It will generally be required to use installation pipes of a larger diameter than the heater inlet connection.
The supply should terminate at each heater with a service cock and a union so as to facilitate the removal of the gas
train for servicing (see Fig 3.1).
Natural Gas
The gas meter and service must be checked by the local gas supply undertaking to ensure that it is adequate to deal
with the total connected load of the completed installation.
Each heater must be provided with gas having the inlet pressure controlled at 20 mbar (17mbar - 25mbar)
L.P.G.
For L.P.G applications each heater must be provided with gas having an inlet pressure controlled at 37mbar (25mbar
- 45mbar) for propane (G31).
