All connections and joints should be
tested for gas soundness with a
suitable leak detector (do not use a
naked flame).
2.1.4. Flue system
The water heater should be fitted
with a flue system connected to the
draught diverter. The flue pipe should
rise for at least 50 cm. vertically before
the inclusion of any bends. If a horizon-
tal run of flue is required this should be
kept to the minimum length possible and
incorporate a rise of 6 cm. per metre of
run. A split clip or flange should be
provided in the flue close to the draught
diverter for ease of servicing.
All flue materials should be
corrosion resistant i.e. stainless steel or
galvanised and must include a tested
and approved terminal to BS 5440 part I.
If the flue passes through any
combustible material measures must be
taken to protect against the possibility of
fire.
All flues must terminate in free air
space approx. 1.5 metres from any
vertical surface of structure i.e.
chimney stacks, roof parapets, etc. If
an existing chimney or flue is to be used
this should be swept clean and be free
of debris before an approved liner is
installed and connected to the water
heater.
2.1.5 Draught diverter
The draught diverted is fitted with a
temperature sensor to signal the
blowback of flue gases.
Important
The T.R.S. should never be put
out of operation. The reentry of
flue gasses may cause poisoning.
