Starting The Gas Fireplace; Pressure Test - RAIS/attika NEXO 100 GAS Installationsanleitung

Starting the gas fireplace

Learn how to start up the gas fireplace after installation in this section.

Pressure test

The fireplace is pre-set to provide the correct amount of heat (kW), which is described under the spec-
ifications. There is no need for further adjustments. "Inlet pressure" (supply pressure to the gas block)
and "Burner pressure" (nozzle pressure) must ALWAYS be measured and if necessary, corrected by an
authorised heating and plumbing and gas installation technician.
1. Close the gas valve (Main Valve Knob)
2. Open the "Inlet pressure tap" on the gas valve and connect a manometer.
3. Check the measurement agrees with the pressure stated on the information plate.
4. Carry out a test of the fireplace at full power including the secondary burners, and when the
fireplace only has the pilot flame lit.
5. If the pressure is too low, check the size of the gas supply pipes to ensure this is correct.
6. If the pressure is too high (more than 5 mbar too high) the fireplace can still be installed but the
gas utility company must be contacted.
7. Loosen the screw to the "Outlet pressure tap" on the gas valve and connect a manometer.
8. Check that the measured pressure agrees with the pressure stated on the information plate.
9. The measured value must be within ± 10% of the stated pressure. This is not the case, contact
the supplier.
NB: After the pressure test is complete and the manometer has been removed, re-tighten the "pres-
sure tap" screws. Check the system for gas leaks.
Mark off the gas type on information plate on the fireplace. It is either natural gas, propane gas or
town gas.
