panel are closed (see Figure 26).

5.Remove the two plugs from the + and – ports of the air orifice taps, thread hose barbs into the 1/8" NPT connections, and attach the manometer pressure lines to the barbs. Be sure all connections are gas tight.

6.Switch on the appliance power switch located on the front of the unit.

7.The Brute Magnum will enter the start sequence. The blower and pump come on for pre-purge, then the ignitor warm-up sequence starts and after all safety devices are verified, the gas valve opens. If ignition doesn’t occur, check that there is proper gas supply. Wait 5 minutes and start the unit again.

8.Open air orifice test port valves. Check air orifice differential at full fire, and make note of the differential.

9.Switch the Brute Magnum off.

10.Close air orifice valves, remove the barbs and replace the plugs. Make sure the connections are gas tight.

11.Remove the two plugs from the + and – ports of the gas orifice taps, thread hose barbs into the 1/8" NPT connections, and attach the manometer pressure lines to the barbs. Be sure all connections are gas tight.

12.Switch on the appliance power switch located on the front of the unit.

13.The Brute Magnum will enter the start sequence. The blower and pump come on for pre-purge, then the ignitor warm-up sequence starts and after all safety devices are verified, the gas valve opens.

14.Open gas orifice test port valves. Check gas orifice differential at full fire, and make note of the differential.

15.Close gas orifice valves, remove the barbs and replace the plugs. Make sure the connections are gas tight.

16.If gas and air orifice differentials match what is shown in Table 7, and do not differ from each other by more than 0.1" w.c., the unit is properly set up. If not, consult, the factory.

17.After placing the appliance in operation, the Burner Safety Shutoff Device must be tested. To test:

(a)Close gas shutoff valve with burner operating.

(b)The flame will go out and blower will continue to run for the post purge cycle. One additional attempt to light will follow including pre-purge, ignitor on, valve/flame on and post purge. Ignition will not occur as the gas is off. The ignition control will lockout, and will have to be reset before the unit will operate.
