Gas Connections

Note:

The furnace retort is not designed to operate as a pressure vessel,

and is fitted with a pressure relief valve at the exhaust. To mitigate the
risk of pressure build up, before each use, check that the retort exhaust
pipe is free of any obstructions e.g. condensed tar.

l

The main gas supply inlet is situ-
ated at the rear of the furnace
beside the water inlet and outlet.

l

The gas supply line to the retort
is fitted and contained within the
main furnace body and does not
require assembly.

l

All connections are secured with
10mm compression fittings.
