Air Supply to Boiler House - Engineering ToolBox
Temporary air intakes - such as windows and doors - should be avoided since they may be closed (and often they are when persons in the boiler room feel the cold) and cutting off the boiler's air supply. If combustion air supply is limited the fire starts to smoke, incomplete combustion occur and carbon monoxide is generated. If the fire goes
Replacing Central Heating Pipes for a Combi Boiler
The system should be vented directly off the boiler flow pipe, as close to the boiler as possible. The cold feed entry Feed / expansion should be inverted and MUST be positioned between the 450 (18") cistern Mimimum Page 9 INSTALLATION BOILER ASSEMBLY - Exploded view Classic FF 230 shown LEGEND 1A.
