I am running an underground poly gas line from my outdoor meter around my house ...into my house to feed a 48" pro style range, a natural gas insert in a masonry chimney and a direct vent wall heater.
Farthest appliance is the insert at approx. 100' from the meter...total btu load for the 3 units is 233k btu's
158k btu for the range, 40k btu for the insert and 35k btu for the wall heater. Range has a 3/4" connection but the manufacturer recommends a 1" feed line.
2 questions
1) If I have sized this properly I need 1 1/4" pipe to supply the btu's needed ?
2) Do I have to run the 1 1/4" directly to each appliance then size it down or can I branch off the 1 1/4" main line as it enters the house and run smaller feeds according to the appliance ? Does that make sense...
Also, the chances of me having all 3 appliances running wide open at once is pretty slim, so what about a 1" line from the meter @ 100'...looks like it will give me 209k btu's....a little shy of what I need but easier to work with.
I am a firm believe that bigger is always better, especially with gas so......
Any and all advice is greatly appreciated..
