rod in place of the burner) in the lamp mount.
To do so, remove the lower clamp (19.1). Pull
up the cooling element (19.3) and turn it to the
side. Detach the lower clamp system (19.2)

After installation, the labeling must be upright.
If a glass melt nipple is present (19a.4), posi-

Remove the burner’s dust cover (19b.5) after
you have installed the burner.
