drill size orifice."
"For your safety refer to installation
instructions for conversion procedure."

1.Remove grill, radiants and burners.

2.Remove the burner orifice hoods and

install the black orifice hoods supplied.

3.Replace the burners, radiants and grill.

4.Set manifold pressure to (10) inch water

column. A 1/8" pipe plug on the burner

manifold can be removed for attaching a

pressure gauge. Remove the slotted

cover from the pressure regulator and

invert the plug. Replace the cover on

the regulator andthe manifold plug.

Regulator is now set at 10" W.C.

CHECKING FOR GAS LEAKS

Soap and water solution, or other material
acceptable for the purpose of locating gas
leaks shall be used. MATCHES,
CANDLES, FLAME OR OTHER SOURCES
OF IGNITION SHALL NOT BE USED FOR
THIS PURPOSE. Check entire piping
system for leaks.

PILOT LIGHTING INSTRUCTIONS

The broiler is equipped with (6) standing
pilots Model 257 and (4) on Model 255B
and should be lighted immediately after
the gas is turned on.

1.Turn the burner valve knobs to "OFF"

position. CAUTION: If gas valves have

been on and gas has escaped through

the burners, turn unit off and wait 5

minutes to clear gas.

2.Remove valve knobs by pulling off.

3.Open front door panel.

4.Light pilots with match, using match

holder furnished with unit.

SHUTTING DOWN INSTRUCTIONS

Turn the burner valve knobs to the off

position to turn burners off.

PILOT LIGHT REGULATION

The pilot lights on this broiler have been
adjusted at the factory. However, due to
variations of gas pressure in different
locations, the pilot light flames may have
to be adjusted at installation location.
Adjust pilot light flames as small as
possible, but high enough to light
burner immediately when burner valve
is turned on high.

BURNER OPERATION

To ignite burners, turn burner valve
knob to "HI" position. There are (6)
burners for Model 257 and (4) for Model
255B, and each one is controlled by an
individual high-low, on-off valve. An
infinite number of broiling temperatures
may be obtained by turning the burner
valve knob to any position between high
and low.

BURNER ADJUSTMENT

1.Turn burner valve knob to "HI"
position.

2.Slowly decrease openings of air
shutters to give a soft blue flame
having luminous tips, then slowly
increase openings to a point where
the yellow tips disappear and a hard
blue flame is obtained.

3.Set the low adjustment to maintain
approximately 1/8" high flame by
turning the screws inside the valve
shafts when the knob is turned to low.

EXHAUST CANOPY

Open hearth broilers inherently create a
good deal of heat and smoke and should
be installed under an efficient exhaust
hood with flame proof filters. A vertical
distance of not less than 48" shall be
provided between the top of the
appliance and filters or any other
combustible material.

AIR SUPPLY

Provisions for adequate air supply must
be provided.

AIR INTAKES IN BOTTOM

Air for combustion enters from the
bottom of the unit. Do not obstruct this
area.

OPERATING INSTRUCTIONS

LIGHTING

When broiler is first lighted, it will
smoke until the preservation oils and
impurities are burned off. When it stops
smoking, it is ready to use.

BROILING

Turn valves on and pre-heat unit on "HI"
before attempting to broil. You will have
to experiment with the grill settings and
the valve settings for your particular
meat products. We recommend that you
set the grate at the full tilt position to
start with. This position allows the
grease to run down the rods into the
grease tray, reducing flare ups.

CAUTION

Hot fat that drips onto the radiants
causes some flare ups. Check water
pans frequently and add a sufficient
amount of water when necessary.
Hot water vapors rising from the
water pans and through the
combustion chamber, helps reduce
flare ups. Exercise care when using
your broiler.

TILTING THE GRILL

CAUTION

Charbroilers are hot! Never attempt
to change the grill position while
meat products are cooking. Flare
ups can occur unexpectedly. Turn
off charbroiler and allow the
charbroiler to cool.

Raise or lower grill by lifting the rod, at
the back of the charbroiler, on which the
grill rests, by its handles and placing the
rod on the next step of the rod brackets.
Use potholders or gloves to reposition
the rod.

ADJUSTING HEAT PATTERN

The broiler has six (6) heat zones on
Model 257 and four (4) on Model 255B,
controlled by individual valves. It is
possible through this arrangement to
have a high heat or searing section,
while having a low heat finishing or
holding section. For the searing
operation, set the valves for the section
at a position of "HI" or close to it. For
holding or finishing, set the valves closer
to the "LOW" position on the dial. You
select the heat pattern you like, and set
the valves accordingly.

CLEANING

Clean regularly; remove grate sections to
sink for washing. Rods rotate for easy
scraping. Brush out carboned particles
from the radiant area. Remove and wash
water pan and grease trough. Wipe
exterior stainless surfaces with
detergent and a cloth. A non-abrasive
cleaner can be used on caked areas.

GREASE PAN

A grease pan is located at the front,
inside the water pan and can be
removed from the front for cleaning. This
pan should be checked and emptied
when necessary.

CAUTION

EXERCISE CARE IN HANDLING THE
GREASE PAN SINCE IT CONTAINS
HOT GREASE.

AIR INTAKES IN BOTTOM

Air for combustion enters from the
bottom of the unit. Do not obstruct this
area.

REPAIRS AND SERVICE

This appliance should only be repaired
or serviced by the factory or factory
authorized personnel. Contact the
factory or one of its representatives or a
local service company for service or
maintenance if required.

LOCKING STRIPS

Grease tight locking strips are available
to join this broiler to any other Designer
Series units to form a solid bank. Specify
which models are to be banked and their
order in the line up when ordering
strips.

WATER PAN

There are (2) water pans on Model 257
and (1) on Model 255B which are located
at the bottom of the unit, and are easily
removed from the front of the unit.
Water should be added to the water pans
and replaced as necessary. The water
pans help prevent flare ups and catch
any grease that drips past the radiants.
