Buzzing From Furnace Unit - HVAC

I use to pipe the entire job in BP, but to compete I've changed over to stainless. I can't get myself to run copper even though its allowed. But I always stub out with BP and put a moisture drip on no matter what. Another thing I do is put a gas valve on the start of any flex tubing, I just don't like the idea of a flex tubing not having some type of shut off 'just in case'.

I've been holding back in ordering the IMC because Ohio is so screwed up! They have changed their minds so many times about things! Here in Ohio the IMC doesn't apply to residences of 3 or less, its still up to the local community. The IMC is now the standard for commercial and 4 units, but that was questionable even last year.

Thanks KJ, your certainly a pro

Always have a shut off with-in reach of the equipment. Before the flex as you say is a must, as I have seen flex split into two different pieces!

Buy the set, read them, that way you can be up on the correct practices and perform to a high standard!

Don't let the hacks run you, you run them! Be the best you can be, and people will find out you know your s*it and don't jeperdize their saftey in the process! I don't care what they charge, I know what I have to charge to do things right. If I can't do a job correctly, I don't need or want it! I value my relationship with my other biz partners (like the Liability Ins Co., Bank, etc...) I don't need a job that is going to make me dip into them beause something was done improperly.

Geez.. (same to you, you just need to knew it for yourself!)

The device you are pointing to is a fan relay. Just looking at the condition of those burners it is obvious you seriously need a cleaning. you need to call a local company to clean this for you and replace that non code gas line. burners

Not quite correct Greg. my 95+ has 2 burners. the number of burners depends on the BTU rating not the efficiency.
