The rest of the gas lines I believe are 3/4 inch which feeds my dryer, and 2 gas stoves, I live in a mother daughter so I have a 2nd range on the 2nd floor.
When I had my new Bryant furance installed last year I had a couple of bids and one contractor said the 3/4 inch main coming into the house may need to be upped to 1 inch. The company who ended up doing the job said it was ok.
I find it funny that the furance is only fed w/ 1/2 inch?? isn't that the biggest gas appliance in the house consuming the most BTUs?? How can I tell if that my furance is being starved or any of my appliances are being starved by having a 3/4 main and not 1 inch?? Is there any kind of calculation I can do to determine this?? OR is there a max for 3/4 inch??
Maybe the old rule applies here "if it's not broke don't fix it" but I was just wondering esp. since the furance is only fed w/ half inch and not 3/4?? Could I be losing any effiency? or worse damage it?
Lastly, I was also toldl that if a gas appliance is being starved you will hear a high pitched squeal coming from that appliance? Is this true??
Your help is greatly appreciated,
TIA,
Harvey
