Please get a year 4 going! Thanks for all your help!
Much like the gas venting videos you've done these are exceptional. Taking my Red Seal Gas-B (sheet metal worker) tomorrow and these are great refreshers. Thanks for taking the time.
Did ya pass?
Hey, great video. Can you make one about describing all four categories ?
Hello Sir , we have a tightly sealed house with 38000 btuh water heater and 60000 btuh non direct vent high efficiency furnace . We have a fairly small furnace room say (10 foot by 7 foot area ) Im planning to make a duct for fresh air intake from side of house. As per the numbers it should be a 4 inch diameter, but since my furnace space is confined( less than 50 cu ft per 1000btuh, would it make sense to have a bigger fresh air duct of 6 inch instead to let in more air? Are there any cons to that?? Would it make our basement too cold ?? Any help is appreciated
It doesn't matter that the furnace is in a confined space, that does not factor into this type of sizing.
What you do need to consider is equivalent duct length. High probability you are over 20 feet of equivalent duct length. So go with 5" duct
@@MathematicPlumber Really appreciate your help ! 🙏
How come I was red tagged for air supply when have only high efficiency furnace and water heater
That is because inspectors interpret the code the way they want to. (Even if that is not what the code says)
