Bryant plus 90

[uncle charly]

I think there is air in the gas line to the Bryant plus 90. The reason I'm thinking this is because we ran out of propane this summer. I didn't have him check the furnace because I heat with wood and didn't plan on using it, well it is suppose to be in the negative digits.

Purging air

Open the pilot manually and wait about two minutes. this should purge out any air.
normal propane pressure is about a 11 inch water column.
