Table 7
*Where the terminal is
within
1 metre of
any
plastic material, such material
should
be
protected from the
effects of combustion products of the fuel.
There are additional general requirements
in
most
Regulations
and
Standards
that
the flue
must
be
~
positioned so
that
it
does
not
cause a nuisance
and
permits the dispersal of combustion products. ®
