Measure the CO

level.

Remove the seal from the gas valve adjusting screw
(64) and adjust the CO

level to the figure given in

Table 16 for min. rated heat output.

Fig. 47

Recheck the levels at min. and max. rated heat output
and re-adjust if necessary.

Turn the temperature control

anti-clockwise as

far as the stop so that the display shows 0.
(= Normal operating mode).
