22. CHECK OF COMBUSTION PARAMETERS

To measure combustion performance and the toxicity of the products of
discharge pipe at a distance from the boiler equal to twice the inside diameter of the pipe itself.
The following parameters can be measured through this hole:
• temperature of the combustion products;
• oxygen (O ) or carbon dioxide (CO
2
• carbon monoxide (CO) concentration.
The combustion air temperature must be measured close to the point where the air enters the boiler.
The hole, which must be made by the person in charge of operating the system when it is commissioned, must be sealed
in a way which ensures that the combustion product discharge pipe is airtight during normal operation.

23. OUTPUT / PUMP HEAD PERFORMANCES

This is a high static head pump fit for installation on any type of single or double-pipe heating systems. The air vent valve
incorporated in the pump allows quick venting of the heating system.
