Appliance Protection
The following pages detail types of appliance protection. Each
design requires several factors:correct nozzle choice,correct noz-
zle height above hazard, correct nozzle location and correct aim-
ing point.
Fryer—Single Nozzle Protection
1. Design requirements for fryers are broken down into two
types.
A. FRYERS WITHOUT DRIPBOARDS
If the fryer does not include a dripboard, measure the
internal depth (horizontal dimension from front to back)
and length of the frypot.
B. FRYERS WITH DRIPBOARDS
If the fryer includes any dripboard areas, measure both
the internal depth (horizontal dimension from front to
back) and length of the frypot portion, and then measure
the internal depth and length of the overall hazard area
including any dripboard areas.
2. Using Table, "Maximum Cooking Area Dimension — Single
Nozzle Fryer Protection,"determine which nozzle is needed
to protect the fryer based on the maximum dimensions listed.
A. If the fryer does not include a dripboard, use the maxi-
mum dimensions listed in the first column of the table to
select the correct nozzle.
B. If the fryer includes any dripboard areas, use both the
maximum frypot dimensions in the first column of the
table, and the maximum overall dimensions in the second
column of the table to select the correct nozzle. None of
the maximum dimensions in either column may be
exceeded.
3. If either the maximum frypot or the overall sizes are exceed-
ed, an additional nozzle(s) will be required.Refer to the mul-
tiple nozzle requirements.
Example:A fryer with a dripboard. The inside of the frypot without
the dripboard measures 18 in. in depth x 18 in. in length(46 cm x
46 cm) and the inside of the overall area including the dripboard
measures 18 in. in depth x 24 in. in length (46 cm x 61 cm). From
the Table "Maximum Cooking Area Dimension — Single Nozzle
Fryer Protection,"either the 3N or the 290 nozzle should be select-
ed to protect the fryer, depending on the maximum nozzle height
above the fryer and the positioning requirements allowed.Refer to
appropriate Figures.

obtain the area of the frypot in square inches.
B. FRYERS WITH DRIPBOARD(S)
If the fryer includes any dripboard areas, measure both the
internal depth and length of the frypot portion, and then
measure the internal depth and length of the overall hazard
area including any dripboard areas.
Determine the area of both the frypot and the area of the
overall vat by multiplying corresponding depth and length
dimensions.
2. Divide the frypot or overall vat into modules,each of which can
be protected by a single nozzle, based on the maximum
dimension and area coverage of the nozzle as specified in
Table, "Maximum Cooking Area Dimension—Multiple Nozzle
Protection."
A. If the module considered does not include any portion of
the dripboard, use only the maximum frypot area and max-
imum dimension listed in the first column of the table to
select the correct nozzle.
B. If the module considered includes any dripboard areas,use
both the maximum frypot area and dimension listed in the
first column of the table,and the maximum overall area and
dimensions listed in the second column of the table to
select the correct nozzle.
3. None of the maximum dimensions in either column may be
exceeded.If either the maximum frypot or the overall sizes are
exceeded,the area divided into modules will need to be rede-
fined with the possibility of an additional nozzle.

Multiple Nozzle Fryer Protection—Tilt Skillet/Braising Pan
Protection for tilt skillets or braising pans is to be based upon the
coverage limitations provided for deep fat fryer protection.Refer to
•Section IV, DESIGN, starting on Page 4-10, for maximum fryer
nozzle coverages and maximum fryer nozzle height limitations.
Although the maximum 6 sq.ft.total surface cooking area require-
ment applies to fryer protection, it does not apply to tilt skillets or
braising pans.
Each tilt skillet/braising pan protected module must not exceed the
fryer limitations for "MAXIMUM SIZE MODULE OVERALL WITH
DRIPBOARD"coverage per nozzle as described in Table on Page
•4-11.
Tilt skillets and braising pans generally utilize a hinged cover.Fryer
protection nozzles are to be placed toward the front of the appli-
ance to minimize the potential for the tilt skillet or braising pan
•cover to interfere with the nozzle discharge.See Figure 25.
