Extinguishing
17. Fully close the cock and solenoid valve located immediately before the burner, and check to
confirm that the fire has been extinguished.
※Stop the blower after the in-furnace temperature lowers to below 500℃ to protect the nozzle.
8) Inspection (Burner Nozzle, Ceramic Tube)
1. Confirm that the shut-off valve, the solenoid valve and the combustion blower are powered OFF.
2. Loosen the union and others of the gas piping.
3. Loosen the “hexagon headed bolts”⑰[⑯] fixing the “Air body”⑥[⑤] and the “Gas body”⑦[⑥].
4. Hold the “gas body” firmly, and pull out “burner nozzle”⑧[⑦], “gas pipe”⑨[⑧], “Ignition plug”
⑩[⑨] slowly and simultaneously.
5. Remove the union or the flange from the air piping.
6. Loosen the nuts fixing the burner to the furnace body.
7. Remove the “Air body” and “ceramic tube”① very carefully from the furnace body.
8. The “Ceramic tube” is removed after removing the “air body”. (If an excessive force has to be
applied, be very careful not to break the “ceramic tube”, “ceramic receive packing”④[③] and
“ceramic Support Packing”⑤[④].)
9. If the insulator or the like of the ignition plug has irregularities, such as crack, replace it
immediately (or ignition failure will be caused).
10. To replace the “burner nozzle” by a new one, loosen the “hexagon socket setscrew”⑮[⑭].
11. Check the ceramic tube on the state of the inside and outside. If the combustion tube is broken,
contact us for consultation as combustion may often be hampered.
12. Reassemble the burner by reversing the order of the above steps.
※Inspect and clean the burner and its accessories from time to time according to the operational
conditions.
