All, our Hayward 400K BTU heater sits under the house soffit, I have soffit vents all along the underside for almost the whole length of the house. Last weekend with little to zero wind when I cranked up the heater our interior smelled like heater exhaust gasses (entered through vents). Now with that said, I aired out the house and have not run the heater since. although with cooler nights and the spa it is about to get kicked on.
If I purchased the Hayward vent stack adapter and ran a vent pipe 2.5ft to 3ft above the roof line where the heater sits is this enough clearance to insure no more exhaust gasses come in via the Soffit vents?
Also since it is all exterior do I need double walled vent pipe? Yes I will add a vent cap.
Thanks
