Gas Appliances

03/29/2010 10:01 AM

why don't all gas appliances come with a specific and concise conversion from NAT to High altitude Nat or lp? it is so wasteful and dangerous to run these things using "their" book. most appliances can and should run optimaly. we can do this.

You seem to be a "broken record" about this issue. From what I understand, there are state and local codes for appliance gas manifold pressure derating based on elevation. The installer would be responsible for ensuring that this is done, not the manufacturer. This is a well-known issue as evidenced by the existence of said codes. I just don't see the problem.
