Figure 28. Gas Trains.

The gas and electric controls on the appliance are engineered for long life and dependable operation, but the safety of the equipment depends on their proper functioning. It is strongly recommended that a qualified service technician inspect the basic items listed below every year.

a.Ignition control

b.Water temperature control

c.Automatic gas valve

d.Pressure switches

e.Blower

f.Mixing control

7.2.1Burner

Check the burner for debris. Remove the fan assembly to access the burner. Remove the 6 nuts, which hold the burner in place. Pull burner up and out. Clean burner, if necessary, by blowing compressed air from the outside of the burner into the center of the burner, and wipe the inside of the burner clean with glass cleaner. A dirty burner may be an indication

of improper combustion or dirty combustion air. Determine the cause, and correct. Always replace the burner gasket when replacing the burner.

7.2.2Filter

The filter used in the Brute Magnum is washable with an 83% arrestance. Since the filter is washable, it will only need replacement in very rare cases. If filter replacement is needed, it should only be replaced with

factory parts. To access the filter, remove the unit’s front panel. Disengage latch on top of filter box and remove the filter box cover. Inspect the air filter. If there is debris on the air filter, remove it from the filter box, and wash it with mild soap and water. Ensure that the filter is completely dry before re-installing, in reverse order.

7.2.3Modulating Gas Valve

The modulating gas valve consists of a valve body and a pressure regulating electro-hydraulic actuator. It provides the air/gas ratio control for the unit. It is designed to operate with supply pressures of 4-13 inches w.c. (1.0 to 3.2 kPa).

To remove the valve actuator, shut off 120-volt power and the gas shutoff valve. Remove the front panel from the unit. Label the four pressure tubes that are connected to the valve actuator, to ensure that they will be replaced correctly and disconnect them from the actuator. Remove the four tubes from the barb connectors. Disconnect the 120-volt wires from the actuator. Remove the valve actuator by taking out the four screws, and pulling the actuator out. Re- install in reverse order. Turn on gas shutoff valve and 120 volt power and check appliance operation and tightness of gas valve connections.

The gas valve body will rarely have to be

removed. If there is a valve problem, and it has been determined the actuator is working properly, the gas valve body may need to be replaced. To remove the gas valve body, shut off 120-volt power and the gas
