I did exactly the same thing about 12 years ago when I started boiling on a turkey frier I went inside to watch some basketball 20 mins later asked my son to add syrup and he came right back in telling me of the big hole in bottom of the pan. If pan froths up and no one is there to turn down the gas you would do that in a very short period of time.
110 taps W.F Mason 2x3 and two turkey friers for finishing
2011 expanding to a Mason 2x4 with a blower increasing taps to about 200
2011 Hurricane Irene rips thru my small sugar bush cost me to lose 20% of taps
2014 I have reworked my lines for 2014
32 taps on 5/16 line with check valves
57 taps on 3/16 line with check valves
55 buckets with total tapped trees of 144
