Roberts Gorden POP-ECA/PGP-ECA 015 to 0100 service manual Servicing 12.1 Servicing Instructions

SECTION 12: SERVICING

SECTION 12: SERVICING 12.1 Servicing Instructions

After commissioning, the heater will require maintenance to be carried out annually. If the heater is used in a dirty or dusty area, more frequent maintenance may be necessary.

Installation, Service and Annual Inspection of the heater must be done by a contractor qualified

in the installation and service of gas or oil-fired heating equipment.

WARNING

Cut Hazard

Turn off fuel and electrical supply before maintenance. Fan can start automatically at any time.

Failure to follow these instructions can result in severe injury or product damage.

NOTE 1: After any maintenance or repair work, always test fire the heater in accordance with the commissioning instructions on Page 33, Section 10 through Page 39, Section 10.10 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 45, Section 14 through Page 50, Section 14.7.

NOTE 2: Check all fuel pipes and pipe joints to ensure there are no cracks or gas leaks. Any cracks in the pipes or pipe joints must be repaired.

NOTE 3: Inspect all suspended components and hardware. Insure that they are in good condition, properly tightened, and corrosion free.

12.2 Burner Maintenance

1.See the manufacturer’s information for specific instructions.

2.Clean the fan (and fuel filters, when fitted). Inspect all components, including the flame monitoring and ignition system, and correct operation of fuel control valves.

3.For oil-fired burners it is recommended that the atomising oil nozzle be replaced during the annual service.

12.3Fan/Motor Assembly Maintenance (all models)

The main fan bearings are permanently sealed and do not need lubrication. Before cleaning, turn off fuel and electrical supply. Remove the heater side panels and use a small brush or duster to clean the fan blades from each side. Replace panels when done.

Check the condition and tension of the drive belts. The condition is best inspected with the belts removed. Check for chaffing or lateral cracks. Replace belts as a matched pair as necessary.

Do not over-tighten belts, as this may cause bearing damage.

12.4 Heat Exchanger Maintenance

Ensure that the front collector box is clean and that the turbulators fitted to the tubes are in good condition.

Also inspect the joint between the heat exchanger and the flue to ensure that it is still sealed.

1.If maintenance is needed, remove the burner. See Page 51, Section 15.1.

2.Remove the upper front panel.

3.Remove the front cover of the heat exchanger.

4.Remove and inspect the turbulators.

5.Clean out any deposits from flue ways and the combustion chamber, using a vacuum cleaner and brush. Inspect the combustion chamber and heat exchanger for damage or corrosion.

6.Any damage must be referred to Roberts-Gordon.

7.Replace components in reverse order to above - replacing gasket material and any damaged turbulators.

8.Inspect and repair any damage to the seal between the flue and the flue spigot.

12.5 Thermal Insulation

While the upper panels are removed for heat exchanger servicing, the thermal insulation fitted to all the upper panels must be inspected. Insulation should be sound, with the foil face in good condition. If any thermal insulation is in poor condition, then it must be replaced with new insulation material and suitably sealed at the edges with adhesive foil tape.
