Installation in exposed positions is not recommended. Account must be made of
the pluming from the flue. If it is likely to be a nuisance to the householder the use
of a vertical balanced flue or conventional flue should be considered.
Terminating positions must be at least 1.8 metres from an oil storage tank unless
a wall with at least 30 minute fire resistance and extending 300 mm higher and
wider than the tank is provided between the tank and the terminating position.
