Failure to follow these instructions can result in death, electric shock, injury or property damage.

13.1 Servicing Instructions

After start-up, the heater will require maintenance to be carried out, at a minimum, annually. If the heater is used in a dirty or dusty area, more frequent maintenance may be required.

IMPORTANT: After any maintenance or repair work, always test fire the heater in accordance with the start-up instructions on Page 26, Section 11 through Page 28, Section 11.3.1 to ensure all safety systems are in working order before leaving the heater to operate. Minor faults may be traced by using the troubleshooting charts on Page 34, Section 14 through Page 38, Section 14.5.

IMPORTANT: Check all gas pipes and pipe joints to ensure there are no cracks or gas leaks. Any cracks in the pipes or pipe joints must be repaired.

IMPORTANT: Inspect all suspended components and hardware. Ensure that they are in good condition, properly tightened, and corrosion free.

13.2 Burner Maintenance

1.Open the door and remove the burner compartment cover. See Page 40, Section 15.2.

2.Clean any deposits from the main burner which may have formed in the injectors or venturi of the burner. See Page 40, Section 15.2.1.

3.Remove the ignition electrode and flame probe. Check condition of ignition electrode and flame probe. Clean off any deposits which may have been formed, check condition of ceramic

insulators. Replace as required. See Page 41,

Figure 15.3.

13.3 Heat Exchanger Maintenance

The heat exchanger will remain clean unless a problem has developed with combustion. Inspect the heat exchanger. Look for signs of overheating at the front tubes which may indicate burner over firing or persistently low air flows.

13.4 Gas Valve Maintenance

No regular maintenance is required on this device. To change gas control valves, See Page 39, Section 15.1.

Do not repair or disassemble gas valve.

Replace faulty gas valves with replacement parts sold and supplied by Roberts-Gordon LLC.

13.5 Flue Blower

The flue blower should not require maintenance. However, if the air pressure switch is causing burner lockout, then remove the flue blower from the vent box by unscrewing the three screws at the mounting plate. Remove the four screws attaching the mounting plate to the fan inlet (See Page 42, Section 15.5). Ensure that the fan is free to run and that the fan wheel is clean.

13.6 Venting and Air Intake Pipe

Inspect all venting and air intake pipe. Ensure that all seams are sealed and suspension points secure. Repair suspension points if any part of the venting or combustion air pipe is sagging. Check to make sure any insulation is not missing or in poor condition. Replace as required. Check all venting and air intake components to ensure they are in good condition, gas tight and corrosion-free.
