another 20-25°F (11-14°C) (when at high fire), and 
it leaves the boiler at 160-165°F (71-74°C).  This hot 
water is then sent to the system.

If the water at the inlet of the copper heat 

exchanger is 140°F (60°C), or higher, the water will be 
allowed to flow through the copper heat exchanger and 
directly to the outlet of the Brute Magnum, and there 
will be a 20-25°F (11-14°C) temperature rise between 
the inlet and outlet of the unit, when the unit is at high 
fire.

The by-pass mixing control displays the mixed 

water temperature, which is the temperature of the 
water that is sent to the copper heat exchanger.  This 
temperature setting is locked and cannot be changed in 
the field.

By pressing and holding the two buttons on the 

left of the mixing control for at least 3 seconds, the 
user will access two available menus.

The first menu allows selection of the temperature 

units.  Pressing the two left buttons for at least 3 seconds 
displays “Uni” on the screen (for units).  Then “°F” is 
displayed.  Press the up or down arrow on the control to 
change from °F to °C, or °C to °F.  When the preferred 
selection is displayed, press the enter (bottom left) button.  
The control will then display “Add” for the second 
menu.  If no more buttons are pushed, the control will 
automatically return to the temperature display mode.

changed.  This setting will be the best suited to most 
Brute Magnum installations.

Fast: Switch 4 to ON position and all others 

to OFF.  If the rate of system recovery to setpoint is 
sluggish with the control set to medium, the “Fast” 
setting may be an improvement.  The “Fast” setting 
will only be used when the rate of change at the sensor 
is very rapid.  In most cases, this setting is too fast for 
the Brute Magnum.

The Brute Magnum has an internal mixing 

system that ensures that the condensation does not 
occur on the finned copper heat exchanger, with 
boiler return temperature down to 70°F (21°C). This 
system, that consists of automatically actuated 
and linked valves, is set up at the factory, and is 
non-adjustable. The return water goes through the 
stainless steel heat exchanger, then to the mixing 
system (see Figure 7).

If the water at the inlet of the copper heat 

exchanger is less than 140°F (60°C), water from the 
outlet of the copper heat exchanger will be directed 
back to the inlet of the copper heat exchanger, and will 
mix to bring the inlet water up to 140°F (60°C).  Once 
through the copper heat exchanger, the water picks up
