Who is we do you have a mouse in your pocket your statement does not answer the Why of the previous post
Sorry Charley We as in the CSA authority. Natural Gas and Propane installation code.
What does C air have to do with return air distance from the flue on a 90% furnace???
I am asking you to explain this circumstance help me to understand as I am the newbie and you are the instructor
I’ll make it easier. Explain it to me THE newbie. I kinda see your point Kevin but I need it explained better.
I am outa here was just informed a free meal waiting:D:D
10 feet has been a rule for some time. Now since the manufacturers say nothing about it is best that you go with your AHJ.
I am not sure what your area would be but 3 feet may be the standard.
Could it effect the flame not likely unless the room was well sealed.
We just by pass this now and say it is best to provide enough air for combustion by a vent to outside.
You still don’t get it C air never was a question in the orginial post by the Pope. Your walking in circles evading my quesion do I need to explain this to you like you were the Newbie. I detest these threads that carry on and on that is a Larson and Jonas thingy not me
He’s just getting started Charley. This thread is doomed…
You stated that it was a HE disposable. So was the return opening underneath the platform?
The problem was the returns proximity to the furnace, and in that room it was unable provide the volume of air that was needed for the supply side.
Yes sir.
It is in the CODE 1602.2 2.3
Who is it that said “a little knowledge is a dangerous thing”?:roll:
If you add up all the restriction back to the combustion that might be more than 10 feet.:mrgreen:
This is the code regarding return air. This code does not discuss the combustion air you brought up.
:roll:
How about 1601.3.8, or maybe 1701.3?
I don’t get it.
In mine that is Flood Hazard Areas. M1601.3.8
You will not find a code that says you have to install air supply vent to outside unless you cannot provide enough air for the proper burning process.
As Will pointed out it is better to take air from outside.
Kevin you are mixing to different topics which is very confusing. The discussion Will was commenting on was regarding combustion air for HE furnaces.
The topic of this post is regarding the location of the return air in relation to the furnace install which so happens corresponds to the code you posted.
Why do you post a code about one topic and then starting commenting about a unrelated thread?
I know for myself that I use this board as a learning tool, but when you are mixing up topics trying to prove some kind of point it makes it difficult.
Because there are two issues involved. One is the return and the other is the combustion air required. They both go together and it was asked why it is different with HE. Only if the air is taken from inside the home.
