Hello! We have in the building a machine room that has two Rheem high recovery water heaters of 300 liters of 50,000 Kcal / h and a low pressure steam boiler of 400,000 cal / h. We are being required that the boiler room that is in a 2nd floor has a 50 cm x 50 cm ventilation duct with an exit to the outside. That implies making a 140 meter pipeline. What rules regulate that pipeline? The NAG 201? If we take out the hot water tanks and put a large one of 600 liters, can we reduce the width of the pipeline? What inclination do you have to have? Greetings and thanks.

Hi Having regard to the powers of the artifacts, which in addition to the provisions of NAG 311, NAG 314 and NAG 318 and must comply with provincial provisions on pressure vessels in residential buildings, what corresponds is to give intervention to a Engineer specialized in COMBUSTION, to carry out the calculations corresponding to ventilation openings, injection of clean air and evacuation of stale air; it is not something so simple as to be treated in a forum; I am a 1st gasist and when a similar case is presented I derive the calculation and project to a combustion Engineer. Regards !

It is that otherwise they will not accept the work, it is not to execute it alone, they will ask for the technical documentation

Good afternoon, this outdoor ventilation is required in order to guarantee the replacement of the air consumed by the combustion of gas appliances. This ventilation must take outside air, but it does not need to be at four winds, so it can be taken from an internal courtyard or from the street. It must be sufficient to meet the demand of the combustion equipment of greater capacity, in this case the boiler burner. The minimum measure is 0.20 square meters up to a capacity of 1,000,000 Kcal / h. Atte, Lucas Foncuberta IDS BOILER SRL
