Pressurised ring main system
This system is used to supply a number
of units from a common storage tank.
A booster pump is used to provide the
pressure to push the oil around the ring
main and back to the tank.
Pressure reducing valves should be fitted on
the delivery pipe to each heater to ensure
that the pressure at the burner pump is less
than 6 psi.
The internal by-pass plug must be
removed from the burner pump
when used in a pressurised ring
main application.
Pipe work and fittings
Galvanised or plastic pipe work
and fittings must not be used.
(See BS 5410 Part 1)
All joints must be sealed properly,
if necessary using PTFE tape or
other approved sealing media.
The pipe work must be effectively
sealed so as to prevent the ingress
of air. The fire check valve must be
operated by way of a fusible link
positioned so that it is above the
burner.
Note: It is advisable to check all pipe
work prior to installation to ensure that
there is no loose debris or scale present.
The oil feed to each heater must be fit-
ted with a fire check valve and isolating
valve.
Black iron pipes can be hammered to assist
in the removal of these contaminants
