To provide the stove with fuel at the correct pressure it will be necessary to have the tank outlet at the maximum
3  meters  (118  inches)  above  the  stove’s  metering  valve  top.    The  hightest  fuel  level must  never  be  allowed  to
exceed 3 meters above the valve top.  If these limits cannot be achieved a secondary reservoir with a lift pump or
level control valve must be fitted.  You will need to refer to the relevant building regulations and local bye-laws
for any restrictions on tank  position relative  to buildings and boundaries  together with the provision of barrier
walls that may exist in your area.
Whatever  type  of  tank  you  fit  it  must  be  equipped  with  two  outlets,  one  to  supply  the  stove  and  one  at  the
opposite end through which to drain off any accumulation of dirt or condensate from the tank. To facilitate this
the tank must be mounted to allow a fall, away from the stove outlet end and towards the drain, of 0.8 inches for
every 1 meter of tank length.

If  a  metal  tank  is  installed  it  may  be  supported  on  brick  piers  insulated  from  the  tank    with  a  waterproof
membrane.  A polyethylene tank must be supported over its entire base area.
Do not underestimate the weight of a full oil tank, it is heavy and must be supported with adequate foundations
and plinth.  All cemented support must be allowed sufficient time to cure before fitting the tank.

Tank Fittings and Pipework

An  isolating  valve  must  be  fitted  directly  to  the  tank  outlet,  allowing  for  the  maintenance  of  the  other
components in the pipeline.  These components should include a metal bowl oil filter mounted to allow adequate
room for the removal of the  sediment bowl  and filter element without  difficulty.   The filter element should be
cleaned or replaced at least annually.  We do not advise the fitting of plastic bowl oil filters as we consider them
too fragile for outdoor, unprotected situations.

Whilst  the  pipework  from  the  tank  to  the  stove  may  be  in  either  steel  or  copper,  the  fitting  of  steel  pipe
necessitates regular maintenance, therefore, the use of plastic covered copper pipe is recommended because it is
easily installed and virtually maintenance free.  The use of galvanised steel pipe is prohibited because zinc reacts
with the fuel.
Where it is possible it may be desirable to bury the pipe, and whilst this is perfectly acceptable it must be done
with the utmost attention to the protection of the pipe from damage, both during the installation and throughout
its life, as it will not be possible to make inspections for leaks after installation.

Before the pipeline enters the building a fire valve should be fitted which will cut off atomatically the oil supply in
the unlikely event of the stove overheating.  This valve is controlled by a remote sensing element situated within
or near the stove and above the metering valve.  Finally, another manual isolation valve should be positioned as
close to the stove as possible to enable all supply to be turned off for stove maintenance.
It is possible to bury oil tanks, install them in house cellars and end oil pipework over a tortuous route of many
hundreds  of  yards,  but  any  oil  installation  other  than  the  most  simple  should  be  attempted  only  by  suitably
qualified and experienced personnel, with the written approval of your insurance company.
