OPERATING INSTRUCTIONS
6.1  Filling the Boiler System
1. 
Ensure the system is fully connected. Close all 
bleeding devices and open make-up water valve. 
Allow system to fill slowly.
2. 
If make-up water pump is employed, adjust 
pressure switch on pumping system to provide 
a minimum of 12 psi (81.8 kPa) at the highest 
point in the heating loop.
3. 
If a water pressure regulator is provided on the 
make-up water line, adjust the pressure regulator 
to provide at least 12 psi (81.8 kPa) at the highest 
point in the heating loop.
4. 
Open bleeding devices on all radiation units 
at the high points in the piping throughout 
the system, unless automatic air bleeders are 
provided at such points.
 
Note that there is an air bleed (coin vent) 
located in the back of the unit, on top of the 
flue collector, to bleed air from the secondary 
(stainless steel) heat exchanger.
5. 
Run system circulating pump for a minimum of 
30 minutes with the boiler shut off.
6. 
Open all strainers in the circulating system, 
check flow switch operation, and check for 
debris. If debris is present, clean out to ensure 
proper circulation.
7. 
Recheck all air bleeders as described in Step 4.
8. 
Check liquid level in expansion tank. With the 
system full of water and under normal operating 
pressure, the level of water in the expansion tank 
should not exceed ¼ of the total, with the balance 
filled with air.
9. 
Start up boiler according the procedure in this 
manual. Operate the entire system, including the 
pump, boiler, and radiation units for one (1) hour.
10.  Recheck the water level in the expansion tank. If 
the water level exceeds ¼ of the volume of the 
expansion tank, open the tank drain, and drain to 
that level.
11.  Shut down the entire system and vent all 
radiation units and high points in the system 
piping, as described in Step 4.
12.  Close make-up water valve and check strainer in 
pressure reducing valve for sediment or debris 
from the make-up water line. Reopen make-up 
water valve.
13.  Check gauge for correct water pressure and also 
check water level in the system. If the height 
indicated above the boiler insures that water is at 
the highest point in the circulating loop, then the 
system is ready for operation.
14.  Refer to local codes and the make-up water 
valve manufacturer’s instructions as to whether 
the make-up water valve should be left open or 
closed.
15.  After placing the unit in operation, the ignition 
system safety shutoff device must be tested. First, 
shut off the manual gas valve, and call the unit 
for heat. Main gas terminals will be energized, 
attempting to light, for seven (7) seconds, and 
then will de-energize. The unit will go into 
lockout mode. Second, turn the power off, press 
the manual reset button on the ignition control, 
open the manual gas valve and allow the unit 
to light. While the unit is operating, close the 
manual gas valve and ensure that power to the 
main gas valve has been cut.
16.  Within three (3) days of start-up, recheck all air 
bleeders and the expansion tank as described in 
Steps 4 and 8 above.
Important: The installer is responsible for 
identifying to the owner/operator the location of all 
emergency shutoff devices.
 
 WARNING
Do not use this appliance if any part has been 
under water. Immediately call a qualified service 
technician to inspect the appliance  
and to replace any part of the control system and 
any gas control that may have been  
under water.
6.2  Operating the Burner and Set Up
The Brute Magnum modulating appliance utilizes 
an advanced, state-of-the-art design. The setup must be 
checked before the unit is put in operation. Problems 
such as failure to start, rough ignition, strong exhaust 
odors, etc. can be due to improper setup. Damage to 
the boiler resulting from improper setup is not covered 
by the limited warranty.
REQUIRED TOOLS:
Differential pressure gauge capable of reading 
negative 0.01 inches W.C. (0.002kPa).
1. 
Using this manual, make sure the installation 
is complete and fully in compliance with the 
instructions.
2. 
Determine that the appliance and system are 
filled with water and all air has been bled from 
both. Open all valves.
3. 
Observe all warnings on the Operating 
Instructions label and turn on gas and electrical 
power to appliance.
4. 
There is a gas/air test panel to the left of the 
control panel, at the front of the unit (see Figures 
25 and 32).  Ensure that all four valves on the test
