1) When changing over to liquid petroleum gas, the subsequent burn-
er adjustment must be adapted to the permissible gas input pres-
sure. This adaptation must be made clear by an entry on the type
identification plate (fig. 4-17, item 27) and on the setting type iden-
tification plate (fig. 4-17, item 28).
2) When changing over to natural gas LL/L, this adaptation must be
made clear by an entry on the setting type identification plate
(fig. 4-17, item 28).
