Maintenance
The Bijou 90 requires no maintenance.
From time to time the burner should be cleaned.
Please observe the following cleaning instructions:
Never use water or compressed air to rinse
or blow out burners! This could flush out /
blow out the sealant grease causing the
burner to leak.
1. The maximum temperature for cleaning is 50 °C
(122 ºF).
2. Do not use cleaning agents because of the risk of
chemical reaction.
3. To clean the valve only use a duster or moist
leather (must not be dripping wet)!
4. To clean the burner close the shutoff valve, pull
the hose off the burner and wipe the burner clean
with a cloth or leather. The burner tubes can be
screwed off and cleaned separately.
7. Switching to a
