These regulations are purely indicative. Each installation how-
ever, has its own unpredictable working conditions: actual
nozzle output; positive or negative pressure in the combus-
tion-chamber, the need of excess air, etc.
All these conditions may require a different air-damper set-
ting.
It is important to take account of the fact that the air
output of the fan differs according to whether the burn-
er has its metal cover fitted or not.
Therefore we recommended to proceed as follows:
