Spoke to the gaz company
They recommended a 500 gallon tank based on the kiln pull of 200,000 BTU/HR
A buried tank is $2700 - so we won't be burying it
The 500 gallon tank is only filled 80% or 400 gallons
When it gets to 165 gallons or 1/3 - Mr Freeze visits - so they refill it regularly based on my use
If I use $20 worth of gas a month - there is no charge for the tank
It has to be 10 feet from the building ( on concrete blocks -Doh!!! )and less than 90 feet from the road
They said they would put a gauge on it for me
Propane is $2.67/ gallon these days - so at 20 gal/firing that's ~ $55/load
So I only have to fire every other month to cover the tank
I spoke to Carol at Agway again to get dimensions for the tank
It's 9' 11" ( say 10 feet long) and 37 1/2" ( say 3 ' wide -diameter of the round tank)
So we'll level a pad 3'X10'
There are two legs:
They are 15 inches wide by 37 1/2" when they hit the ground at 5' apart
E-mail conversation with Paul Geil, Bill Schran (refer to drawing below)
RICK: I'm about to lay bricks and I need to know how to get the gas in. Do you know if a second stage regulator will be necessary on the outside of the building?
PAUL: Yes, normally outside.
RICK:Can I bring in the gas pipe on the floor to prevent a tripping hazard (red line), or
Must I bring it in at 8" above the concrete floor (blue line), to "L" down to the connection as you represent on the installation drawings?
PAUL: If your local codes allow the pipe on the floor, it's okay.
RICK:Any thoughts on running the gas pipe up the wall - over the truss and down to the kiln connection? (green line)
PAUL: Yes, we have done this before, this is the cleanest way.
RICK: I read somewhere that the straightest line to the kiln was
like the fewest elbows.If you think the green line plan will not present problems - I might do it
I'll have to check with the gaz company when they deliver the tank next week on their requirements for the regulator and "floor" pipeI think I could also live with a floor pipe with a rubber "threshold" over it
BILL SCHRAN: At school we ran the gas kiln as the red line illustrates in your drawing, well, I guess its actually an inch off the floor.
