The following are possible fault conditions. Check the items mentioned and repair or replace parts as necessary. The list is not
exhaustive but a fair outline of possible faults.
1. No Spark
(a) Check spark by manually operating the spark generator.
(b) Check the spark gap and electrode alignment (see Fig 21). The electrode, thermocouple probe and horizontal arm of the
pilot burner should be in a straight line.
(c) Inspect the spark lead, ensure firm contact at the ends and that there is no shorting out of spark at either end.
2. Spark but the pilot does not light.
(a) Verify availability of gas at the pilot burner, if possible, light with a match.
(b) If gas is available, proceed as in 1 above.
(c) If gas is not available, check the pilot burner and supply pipe for blockage.
(d) Ensure gas is available at the pilot port of gas tap, if not replace the tap.
3. Pilot lights but goes out on heat setting.
(a) Check for linting of the pilot lint trap filter(Steel gauze fitted around the body of the pilot burner) and the aeration hole
under the filter.
(b) Pilot starvation due to partial blockage. Clean the pilot gas supply line. See also 2(c) and 2(d) above.
4. Nuisance shut off.
(a) Inspect the pilot flame.
(b) Check the thermocouple. If faulty replace the pilot assembly.
(c) Check the magnet unit in the gas tap. If faulty replace the tap.
(d) Check the ventilation into the room. Vitiation may be due to the lack of sufficient air supply.
(e) Check for satisfactory clearance of combustion products. Vitiation may be due to spillage of combustion products into
the room.
(f) Remove spigot restrictor if fitted.
5. Main burner popping.
Remove the loose fuel effect components. Light the fire and inspect the burner for cracks and leakage. Replace the burner if
necessary.
6. Poor flame picture.
(a) Remove the burner assembly. Check the alignment of the burner ports with the holes in the base ceramic matrix. Ensure
the ports are clear.
(b) Re-assemble correctly and check the flame picture.
(c) Check the gas rate.
(d) Check fuel effect layout is correct to these instructions.
7. Sooting.
Proceed as in 6 above.
8. Spillage.
(a) Check the seal of the fire to the wall/surround.
(b) Inspect the chimney.
(c) Remove the spigot restrictor if fitted.
(d) Check the fuel effect arrangement.
