Grant Vortex Boilerhouse Combi - Seasonal Effi Ciency, EPR, and NOX Class; Smoke Analysis (Combustion Gases)

2.3 SEASONAL EFFICIENCY, ERP AND NOX CLASS (NITROGEN OXIDE)
2.4 SMOKE ANALYSIS (COMBUSTION
GASES)
To allow the boiler to be put into service and maintained, the boiler
is supplied with a combustion test socket on the front cleaning door.
When this test point is used, please note the following measures:
• The test sample relates only to the CO2 readings and the smoke
opacity test.
• The smoke output and temperature must be taken from a mea-
surement point located on the starting element of the smoke pipes of
the high, vertical and conventional outlet kits.
• The suction cups with low outlet do not contain a test point. The
smoke temperature and effi ciency readings must be taken at the
outlet of the terminal duct.
To allow the boiler to be commissioned and serviced, the boiler is
supplied with a combustion test point on the front cleaning door.
