We just put a new room in part of our cellar. It was recommended that we install an 'outside air vent' to our gas steam boiler (venting to the outside through a window) to make sure that there is enough air flow for the boiler. Is this necessary? If so, who would we contact to install this? Our gas steam boiler is 15 years old.
