MAINTENANCE
GLASS CRYSTAL BURNER REMOVAL / INSTALLATION HZI390PB
Care must be taken when installing the burner into the fi rebox.
Do not damage, knock or scrap the pilot assembly.
The fl ame sensor and ignition lead are fragile and can be damaged
easily.
1) If already installed, removed glass crystals and ceramic spa stones.
2) Remove fi ller sections from right and left sides of burner. Discard fi ller sec-
tion if enamel panels are to be installed - see below.
1) Lift the burner assembly with both hands. Point the mixing tube towards
the rear of the fi rebox. Lean the rear of the burner assembly downward.
Partially lift the burner assembly so that the mixing tube will then slide
into the air shutter.
2) Lower the front edge of the burner assembly so that the burner front
mounting tab rests on the burner mounting bracket left and right, near
the front of the fi rebox. These tabs will not line up unless the mixing tube
is inside the air shutter at the rear of the fi rebox.
