SERVICE CAUTIONS:

Service should be performed only by a
qualified technician. Temperatures found
in these broilers require caution to avoid
any contact with components that

SAFETY CAUTIONS:

1.

The tubular elements are relatively
self cleaning and should never be
scraped with any abrasive tools.

2.

On B-40 and B-406 models the grate
is nested from the top side of the
elements, this requires care in
handling the head assembly not to
raise the head too fast which can
displace the grate if the head up­ward movement stops suddenly.

These Broilers cook various cuts of meat
leaving a cosmetic char branding and a
minimum of fat or grease on the meat.

are subject to high temperatures that may
cause burns. Use caution when handling
or servicing the broiler to avoid causing
damage that may compromise safety.

4.

Allow grates to cool down to a safe
handling temperature before at
tempting to remove them for cleaning.

Always adjust the height of the

5.
grates on the bottom nested units so
that the top of the grate is above
the top of the elements so that there
can be no contact between elements
and the meat being cooked.

On B-44 through B-506 models the
Grate(s) should be nested from the
bottom. These models have 4 bat­wing bolts that mount to the grate
castings tabs on each corner to
position the height of the grate
above the drip pan directly below
the elements.

6.

Never pour water over hot elements.
Never subject heating elements to
caustic sauces or cleaning agents
that may cause corrosion to element
sheaths that may result in splits or
holes in the element sheath.
