Combustion gas discharge

Combustion gases may be discharged by means of hoods connected to a flue
with reliable natural draught, or a fan extraction system. An effective extraction
system requires careful design by an authorised specialist, and must comply
with the regulation distances and positions. After installation, the engineer must
issue a certificate of compliance.
