Use of the Level Guage
WARNING:
CAUTION:
Never remove the clean out screws on the top or bottom of the gauge when the kettle is full. Disregard for
this warning can cause severe burns!
The BoilerMaker™ brew kettle uses a thick wall borosilicate glass level gauge tube that will never cloud,
scratch or discolor or break from normal use. The heavy gauge guard will protect the glass from accidental
breakage, but care must be taken to avoid impacts to the kettle. Broken level gauge glass is not covered
under warranty.
Hops, particularly whole hops, can block/plug the opening of the level gauge affecting the ability to read the
level accurately. Bagging your hops in a muslin grain bag is recommended if this becomes problematic.
If you have foaming/boiling wort in the level gauge glass this is a clear indication that there is too much heat
reaching the external components and you need to improve the heat shielding to them, reduce heat, or both.
The level gauge is calibrated to reflect the liquid level in the kettle and is accurate to approximately 1qt. for the 10/15/20
gallon BoilerMakers™, and approximately 2qt. for the 30/55 gallon BoilerMakers™. During a full rolling boil, it may be
difficult to get an accurate level reading. Turn off heat temporarily to obtain an accurate reading.
To clean the gauge glass after use, remove the set screw in the top and bottom of the level gauge (shown in Fig. 5) using
the ¼” hex wrench provided. Use the included cleaning brush to clean the tube (shown in Fig. 6). When reinstalling the set
screws, DO NOT over tighten them! When you feel the set screw make contact with the bottom of the fitting a small amount
of torque is all that is needed to make the seal. This will prevent premature failure of the threads or damage to the seals.
If you choose to remove and disassemble the gauge from the kettle for periodic cleaning, take care to place the O-rings
in the proper locations. Inspect all O-rings for tears or cuts and replace as needed. Repair kits are available through your
retailer.
Verify the o-ring is present between the kettle and the level gauge end blocks. Reinstall the gauge and tighten the mounting
screws by hand. Insert the 5/16” allen wrench to tighten the nut to 20 ft-lb (27 N-m)(Shown in Fig. 10). DO NOT over tighten!
A firm pressure is all that is needed to seal the joint. Take care to prevent the end block from rotating, which will crack the
glass!
Note:
If using metric volumes, remove sight glass gauge and invert, and reinstall for liters scale.
Warning:
The handles of the BoilerMaker™ brew kettle are installed at the factory and should not be removed for any
reason. Before each use, ensure that the nuts are tight! If you notice a loose nut, tighten it with a torque wrench to 32 in-lb.
(3.6 N-m) prior to using the kettle. Do not over-tighten or joint could be damaged. If for any reason you have damaged, or
suspect you have damaged, a nut/stud do not use the product. Contact your retailer or Blichmann Engineering™ to arrange
for repair of the kettle.
