Check tightness

Danger
Danger! Danger to life by gas!
The entire gas inlet pipe, particularly the joints, must be checked
for leakages before commissioning.
The gas burner valve on the gas burner must be pressure- tested
at maximum of only 100mbar

Venting the gas line

The gas line must be vented before initial commissioning.
For this, open the measuring nozzle for the connecting pressure and vent,
taking the safety precautions into account. Check for tightness of the
connection after venting.

Flue gas connection

For the operation of the EC five as a gas condensing boiler, the flue gas
pipe should be designed with the flue gas temperature under 120°C (flue
gas pipe type B). The flue gas piping system SAS approved in
conformance with building regulations is intended for this purpose.

Important
Connecting the boiler as RLUA-version (RLUA-set and possibly
WAS) may give rise to reduced output of the boiler, which is
compensated by Potterton customer service.
