appliances or 9.2% for LP appliances (to be checked only at full fire). When using an O2 analyzer, the correct O2 is 6.8% for both Natural Gas and LP appliances.

Caution

Should any odor of gas be detected, or if the gas burner does not appear to be functioning in a normal manner, close main shutoff valve, do not shut off switch, and contact your heating contractor, gas company, or factory representative.

6.7 Shutting Down the Brute Deluxe

1.Switch off the main electrical disconnect switch.

2.Close all manual gas valves.

3.If freezing is anticipated, drain the Brute Deluxe and be sure to also protect building piping from freezing.

This step to be performed by a qualified service person.

6.8 To Restart the Brute Deluxe

If drained, follow Section 6.2 in this manual for proper filling and purging.

1.Switch off the main electrical disconnect switch.

2.Close all manual gas valves.

3.WAIT FIVE (5) MINUTES.

4.Set the aquastat or thermostat to its lowest setting.

5.Open all manual gas valves.

6.Reset all safety switches (pressure switch, manual reset high limit, etc.).

7.Set the temperature controller to the desired temperature setting and switch on electrical power.

8.Burner will go through a prepurge period and ignitor warm-up period, followed by ignition.

SECTION 7.

Maintenance

7.1 System Maintenance

1.Lubricate the system water-circulating pump, if required, per the instructions on the pump.

2.If a strainer is employed in a pressure reducing valve or the piping, clean it every six months.

3.Inspect the venting system for obstruction or leakage at least once a year. Periodically clean the screens in the vent terminal and combustion air terminal (when used).

4.Keep the appliance area clear and free from combustible materials, gasoline, and other flammable vapors and liquids.

5.If the appliance is not going to be used for extended periods in locations where freezing normally occurs, it should be isolated from the system and completely drained of all water. All systems connected to it should also be drained or

protected from freezing.

6.Low water cutoffs, if installed, should be checked every 6 months. Float type low water cutoff should be flushed periodically.

7.Inspect flue passages, and clean with brushes/ vacuums, if necessary. Sooting in flue passages indicates improper combustion. Determine the cause and correct.

8.Inspect the vent system and air intake system, and if the vent system is Category III, ensure that all joints are sealed properly. If joints need to be resealed, completely remove existing sealing material, and clean with alcohol. Apply new sealing material, and re-assemble.

7.2 Appliance Maintenance and

Component Description

Only genuine replacement parts should be used.

Caution

Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and dan- gerous operation. Verify proper operation after servicing.

See Figure 5 for location of gas train components. 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 controls

b.Ignitors

c.Water temperature control

d.Automatic gas valve

e.Pressure switches

f.Blowers

7.2.1 Burners

Close main manual gas valve before proceeding. Checking the burners for debris - Remove the ignitor inspection panels(s) and ignitor(s) and inspect the burners through the ignitor hole(s) using a flashlight to illuminate. If there is any indication of debris on the burners that are visible, all the burners will need to be inspected more thoroughly. Remove the screws from around the front of the air box (large panel from which the ignitor inspection panel(s) were removed), and remove the large panel. Remove the gas manifold assemblies and the burner panels. Inspect the burners. Clean burners, if necessary, by blowing compressed air from the outside of the burners into the center of the burner. A dirty burner may be an indication of improper combustion or dirty combustion air. Determine the cause, and correct. Replace the burners in the reverse order
