Getting Started
The sheet metal sides and top are easily removed to reduce
the chance of dents and/or scratches in the finish. simply
lift the top off, and that will allow the sides to be pulled away
and up, for removal. To re-install, slide the channel, at the
bottom of each side piece, over the lip at the bottom of the
boiler, and hold downward while moving the side panel into
place. Then slide the top down over the sides.
NOTE: The sheet metal top holds the sides in place,
thus, no bolts or screws are needed.
CAUTION: BOILER SHOULD NOT BE INSTALLED

Locating Boiler
Place the boiler as close to the chimney as possible, while
still maintaining the above mentioned clearances. Bolt the
shaker handle on to the block on the side of the boiler, using
the (2) 5/16 X 3/4 in. bolts and lock-washers.

Install the a350 sensor wire all the way into the immersion
well and screw the well into one of the top hole
Turn the pressure relief valve into the stub on top of the
boiler, next to the supply outlet fitting.
