OPERATION
OPERATING CHECKS
The heating system must be correctly operated to ensure perfect combustion as far as possible with reduced emissions of carbon
monoxide, unburnt hydrocarbons and soot into the atmosphere, and to avoid hazards and damage to people and goods.
Guide to combustion values:
A diagram is provided in which the system efficiency is obtained according to the flue gas temperature, the ambient tempe-
rature and the percentage of carbon dioxide (CO
2
). Dispersions through the boiler casings are not considered.
