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.

2.1.5Draught 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.
