6. Cleaning /
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.
5. Do not dismantle the burner!
6. Never drill out the burner jets.
7. Do not blow out the burner‘s inlet nozzle with
compressed air. This could blow away the sealing
grease and cause the burner to leak.
8. The burner jets must not be screwed out for
cleaning. The burner could start to leak and safe
use is no longer guaranteed.
If the burner nozzle becomes plugged,
disassemble the tubes than hold the burner
with the nozzle facing down. Use a hair dry-
er or other device generating hot air, melt
the wax plug and allow the molten wax to
completely run out.
If this method fails to clean the nozzle, it
must be either cleaned or replaced by an
authorized technician.
7. Switching to a
different type of gas
The Bijou 90 conforms with the regulations set out
in DIN 30665 Part 1 and enables a switch to another
type of gas by changing the set of burner nozzles.

conversion sets are given in the table above. Each
set consists of a small nozzle, a large nozzle and a
sticker naming the respective type of gas. The con-

The changeover of the nozzles must only be
carried out by qualified specialists in ac -
cordance with DVGW regulations (German
