Requirements Of Your System:
IMPORTANT!
Read before unpacking or using this product!
For the TOWER of POWER
tm
control system to function properly, your brewing system must meet
some basic requirements. If your system is unable to meet these requirements please contact your
RETAILER for guidance. We cannot guarantee the performance of the product if these basic
minimums are not met.
Hot liquor tanks perform well on nearly any system that can maintain a moderate flame. Mash Tuns require
a couple basic performance parameters to be met for proper performance.
Important!
Do not use or install the TOWER of POWER
tm
equipment until you verify that your equipment is
capable of the requirements below. If you are using Blichmann Engineering BoilerMaker
tm
mash tun with our
false bottom, and a TopTier
tm
burner you will not have equipment limitations. However, it is still important
that you verify that your crush will allow adequate wort flow! Most stuck mashes are caused by too fine of a
crush. It is also expected that
Your mashing system must have the capability to continuously recirculate your wort using a pump for the
duration of the mash without sticking. The flow rates in the chart below are minimum values.
Finished Batch Size gal (L)
Min Flow GPM (LPM)
5 (19)
0.5 (2.8)
10 (38)
0.75 (3.8)
15 (57)
1.25 (4.75)
20 (76)
1.5 (5.7)
32 (121)
2.25 (8.5)
Important:
Grain bed flow rates are highly dependent on crush quality. Move to a coarser crush if you are
not able to flow at the above rates. It is also recommended that you allow a 10 min dough-in prior to turning
on the pump to allow the air to purge from the grain and for the grain to fully absorb the water.
Burner Requirement:
Your burner must be capable of operating well at low power settings. If you cannot
maintain a flame at about half power your system stability will suffer. Specifically, you should be able to
reduce your heat to achieve an average heating rate of 1.5 F/min or less. To do this, recirculate your wort at
the above rates or faster (use a stop watch and known volume to measure flow rate). Then apply heat on your
burner at the lowest stable level. If over a 20-30 min period the increase in wort temperature divided by the
time is at or below 1.5 F/min you have met this requirement.
Fuel Supply:
The solenoid valve supplied is suitable for up to 25 PSI propane regulators and residential
natural gas. Fuel flow rate through this valve is adequate to power Blichmann Engineering TopTier
tm
burners
on both fuels, however, other burners may need a larger solenoid valve (not included). Do NOT install a
solenoid valve that draws over 2A at 120V including inrush or you may damage the ignition start relay which
is NOT a warrantable failure.
