Check the main injectors
• Inspect the injectors for any sign of damage or blockage and remedy
as required.
Service the pilot:
• Inspect the pilot and flame rods for any signs of damage or wear. By
blocking the main injectors (a silicon tube across both injectors works well)
the fire can be started and operated with just the pilot operating if required.
• Remove the front pilot assembly bracket and the pilot head can be removed
and cleaned; the pilot injector can now also be inspected and cleaned.
• If replacing the pilot injector, remove the retaining nut on the base of the
pilot body and remove the pilot injector using a small, flat screwdriver.
• Inspect the flame rods and leads for signs of damage and replace if
required.
Note:
There might be a slight build-up of soot on the flame rods
and this should be removed to help ensure continued operation.
Service the fan:
• Remove the fan cover by removing the 4 screws holding it in place.
• With the cover removed it should be possible to inspect and vacuum the fan
to remove any build up of dust and lint. Note: if replacement of the fan is
required, the gas will need to be disconnected and the gas control assembly
removed to gain full access to the fan bracket. Replace the cover when done.
Inspect the firebox:
• Check the gas control assembly – valve, control box, regulator, wiring,
panels etc. – for any signs of overheating, water damage or anything else
out of the ordinary and remedy as required.
Reassembly:
• Re-assemble the pilot
• Check that the Aeration Sleeves (if fitted) are in place and in good
condition
• Return the main burner assembly to its correct position and fasten in place.
• Return the burner media as it was. Do not pour the vermiculite, Pebbles,
or Glass onto the burner as any dust that has gathered can block the ports
and cause problems.
