[TheForge] Sidearm burners, Murphy burners & blown burners

[Jerry Smith]

Ladies and Gentlemen,

I have read all of these psotinh on burners. I went to
my local hardware store and bought all the the
pieces/parts. Currently I figuring out check vales,
chokes and other controls on both Frosty's design as
well as the Zoeller design. 


Some things I taken license and done them a different
way, while other I followed the design. I have listen
to every one, but I am out trying these burners. 

I must say I was impressed with the heat you can
create.
