Propane Tanks & Furnaces
I have a question regarding propane tanks and my RV furnace.
This weekend, I had 1 full 30lb propane tank and one 2/3 full (30lb) propane tank on an automatic switch over valve. I had the switch over valve pointing to the 2/3 tank with the tank turned on. I left the full tank turned off. (I intended to turn it on later)
All propane appliances were working fine, except the furnace. The pre-blower would turn on, the burner would ignite for about 8-10 seconds, then fail and shut down. I lived with this the first night.
In the morning, I turned on the valve of the full tank, but did not touch the switch over valve.
Poof, the furnace worked as normal.
As it turns out, for the whole weekend, we still had 2 pounds left in the first tank and never dipped into the full one.
Anyone have an idea of what is going on here? I have been RVing for 30 years and have done this many times (running with one tank open).
