changing connected type of gas a detailed ue gas analysis MUST be done using
adequate CO and CO
2
measuring equipment!
This shall ONLY be done by trained technicians!
Changing the gas setting only by adjusting the CO
2
screw will result in an unsafe ue gas
condition, is dangerous to life and will damage the equipment
!
Note: Yearly maintenance of Gas components is needed:
Clean Burner head, Electrode and interior blower housing from fats and dust! (TI03-2007)

2) Open control panel
3) Set DIP switch 1 on PCB to „ON“ position
4) With timer dial select: „SE“ = Settings:
5) Activate „Settings“ by pressing core temperature key; display changes to „SE1“
6) With timer dial select: SE6
7) Activate position SE6 with timer key (keep key pressed)
8) Select new gas type with timer dial:
G20=Nat Gas H, G25=Nat Gas L, G30=3BP, G31=3P, 13A=Nat. Gas Japan
9) Con rm new gas type with core temperature key (now timer key can be released)
10) With timer dial select: SE7
