How to Read Your Propane Tank Gauge

Tank Gauges:
The majority of our tank gauges are Rochester gauges that display to the number "80." The tank will normally be filled to approximately 80% to allow for heat expansion.  Occasionally a gauge may become "stuck" and often a light tap on the guage will correct this.

91,500 BTU's burn one gallon of propane in one hour.
For example, a gas logs burner that has 40,000 BTUs, would take two hours to burn one gallon of gas if the set ran constantly.
