blown gas burner
FMP
The FMP burner range of compact industrial packaged gas burners covers outputs up to 150 therms, using a very
stable "nozzle-mixing" combustion head and is suitable for use on Natural, LPG or Towns Gas (type must be specified
at time of ordering). They are suitable for firing a wide range of industrial applications. Standard burners should not
be used against a back-pressure, special versions are available to fire into a resistance.

BURNER MOUNTING

All burners are provided with a mounting flange
which is pre-drilled to the dimensions given on the
data sheet and all screwed studs or alternative fixings
should be to these dimensions.
A suitable opening should be provided in the
appliance wall for the combustion tunnel/ quarl.
When the burner is mounted to the appliance, a
distance equal to the overall length of the burner
including combustion tunnel should always be
allowed at the rear of the burner unit to allow for
withdrawal of the burner inner assembly.

VENTILATION

An adequate, dust-free supply of fresh air is required for the burner, at all firing rates, in accordance with the
appropriate standards.

GAS AND ELECTRICAL CONNECTIONS

The gas supply to the burner must be constructed and installed to comply with local conditions and appropriate
codes. When connecting a gas supply it is essential to install a manual shut-off valve, together with a suitable pipe
union, at or near the burner. The burner assembly should not be used to support the incoming gas supply, suitable
brackets or hangers should be used for this purpose. Care should be taken to ensure that the incoming gas piping is
sized correctly to prevent excessive pressure drop (N.B: supply pipework is generally larger than the burner gas
connection).
All electric wiring must be carried out to all applicable Codes and Standards.
Wiring of the burner should be in accordance with the appropriate wiring diagram. A suitable mains isolator should
be placed in a convenient location, and the final electrical connections to the burner should be flexible conduits. It is
vital that the live and neutral wires are connected to their appropriate terminals as shown on the wiring diagram, as
reversal could present a hazard. Earth bonding must be checked, preferably by a "megger".
The burners are all of the "expanding flame" type pilot system and normally use "intermittent" flame failure control
boxes. The pilot valve remaining energised all the time that the main safety shut-off valves are energised. Interrupted
flame failure control boxes, where the pilot valve is de-energised when the main safety shut-off valves are energised,
can also be used.
