NIECO MODEL 9025 -BURGER KING CHAIN BROILER
TWO - SINGLE FLOW POINT NOZZLE (P/N 11982)
The Nieco Chain Broiler Model 9025 is a unique appliance and when fitted with two catalysts it requires the
use of two Amerex nozzles (P/N11982)to protect each half of the appliance. Total appliance protection
therefore, requires the use of a total of four Amerex nozzles (P/N 11982). This unique appliance is actually
two chain broilers put together to accommodate the cooking of two different products at the same time. This
appliance can be fitted with two catalysts (18" x 24" overall) one for each cooking side.
The protection of the appliance is accomplished by using two nozzles P/N 11982 positioned two inches
outside of the catalyst perimeter aimed at the center point of the catalyst. The nozzles are to be located on
opposite ends of the catalyst, 180° apart and are to be 13" to 36" above the top surface of the catalyst. This
configuration is repeated for both cooking sides of the appliance. If no catalyst is used the same protection is
required for the unit.
Note: Maximum & minimum heights
must be measured from the tip of nozzle
to the top surface of the catalyst or
appliance (if no catalyst is used).

October 2003 Section 3 Design Page 3 - 23
Amerex KP Wet Chemical System (EX 4658)
DETECTION NETWORK LIMITATIONS: MRM
Optimum fire suppression system performance relies on proper detection network design. This section
discusses the type of detectors used, their selection, placement and design limitations.
The Amerex KIP Restaurant Fire Suppression System MRM uses a continuous cable, corner pulleys, detector
bracket, detector linkage, fusible links, conduit offset, terminal link connector and a temperature-measuring
device.
The quantity of detectors to be used in a system will depend on the number of ducts, number of appliances
and the location of the appliances under the hood.
DETERMINING DETECTOR LOCATION AND NUMBER OF DETECTORS
In order to detect a fire in the duct, a detector is required to be placed within the duct opening or up to 12
inches into the duct. If it is mounted into the duct, the bracket cannot shield the fusible link from the hot
vapors moving through the duct.
Every appliance under the hood that is being
protected by the suppression system must
have a detector placed over it and positioned
within the path of exhaust vapors.
WARNING: DO NOT LOCATE DETECTORS
DIRECTLY IN THE PATH OF GAS APPLIANCE
EXHAUST FLUE GASES. DOING SO COULD
RESULT IN UNNECESSARY DISCHARGE OF
THE SYSTEM.
GENERAL LIMITATIONS OF DETECTION

Maximum of 24 corner pulleys. (either style)
Maximum of 20 detectors (any combination of temperature settings).
Maximum of 120 feet of cable on the detection network.
No pulley tees are allowed.

FUSIBLE LINK SELECTION
To assure that the appropriate temperature is selected, the temperature sensing device must be used at each
detector location while the cooking line and exhaust fan is operating. Temperatures found at each detector
should be recorded and placed with other documentation in the job file for future reference. Selection of
fusible links should be made according to the temperature measured:

DETECTION NETWORK LIMITATIONS: PRM
Select a suitable location for the pneumatic release module (PRM) that has access for installation, service,
recharge and where both the nitrogen actuation cylinder pressure gauge and the system status indicator can
be viewed. The PRM has provisions for a single, continuous section of detection tubing. No splicing or
"tee's" are allowed. There shall be only two tubing terminations - one at the accumulator cylinder inside the
PRM and the other at the opposite end of the tubing, with the use of an End of Line fitting (P/N 16506). Install
in areas where the maximum expected ambient temperature does not exceed 375°F.

The Linear Fusible Link Detection System provides complete hood fire detection by placing thermal
links at maximum 24" intervals the entire length of the hood. Installing the links in this manner
allows the appliances to be placed anywhere under the hood without having to locate links directly
over each appliance.
A unique system of cable segments, pie-fabricated, has been developed to make the installation of
this system simple and easy. It eliminates the use of conduit, link holders and mounting brackets
under the hood in the plenum area.
The limitations of the Linear Fusible Link Detection System are as follows:
Maximum of 20 detection links and (19) Link to Link Cable Segments.
Maximum of 30 feet of cable used in the Link to MRM Cable Segment.
Maximum of 20 corner pulleys. (either style)
Maximum unsupported detection cable length is 8'-0".
Refer to Fusible Link Selection section, page 3-24 of this manual for proper selection
process. The higher setting links are to be used when higher temperatures are encountered
with appliances such as char-broilers.
The Linear Fusible Link Detection System is for use in single hood applications, or where
multiple hoods are connected "end to end" only. It can not be used for "back to back" hood
arrangements or multiple hoods that are mounted in separate locations and are part of a
single KIP Fire Suppression System.

MANUAL PULL STATION NETWORK LIMITATIONS
Every Amerex KP Restaurant Fire Suppression System installation must have at least one manual pull
station. The manual pull station network consists of cable, corner pulleys, pulley tee, manual pull station(s)
and optional conduit offset.
GENERAL LIMITATIONS OF MANUAL PULL STATION NETWORK
Maximum of 20 corner pulleys per manual pull station
Maximum of 130 feet of cable per manual pull station
Maximum of I pulley tee per network (counts as one corner pulley for each manual pull station)
Maximum of 1 conduit offset per network (must be attached to the MRM and before tee pulley when chosen)
NOTE: Manual pull stations should be installed no higher than 48 inches from the floor and must be
along a path of egress. Consult the local Authority Having Jurisdiction (AHJ) for the final
approval for manual pull station quantity, locations and mounting height and other
considerations prior to finalizing manual pull station mounting details.

MECHANICAL GAS VALVE APPLICATIONS
The PRM or MRM closes the mechanical gas valve immediately upon system discharge. A pneumatic and
mechanical action in the gas trip assembly pulls on a cable attached to the mechanical gas valve, unlatching
the valve and allowing an internal spring within the valve body to provide the closing force. Connection of the
cable from the valve to the PRM or MRM under tension maintains the gas valve in an open position.
MECHANICAL GAS VALVE
A mechanical gas valve trip assembly must be used with any
mechanical gas valve. The gas valve trip assembly (P/N %11t9, 12740) is included with all Amerex manufactured gas valves
but must be ordered separately for use with gas valves listed *40004 PORT NO. 12740 in this manual supplied by other manufacturers.
See Section 3 "System Components" for all mechanical gas valves that
are suitable for use with the Amerex Restaurant Fire Suppression
System. The use of any other mechanical gas valves will avoid the UL
listing for the system installation. All of the listed valves have female NPT
threads. The location of the gas valve should be accessible and approved
by the local Authority Having Jurisdiction. A contractor licensed and
qualified for such work should perform installation of the mechanical gas
valve into the gas line.
MECHANICAL GAS VALVE ACTUATION NETWORK LIMITATIONS
The mechanical gas valve actuation network consists of cable, corner pulleys, pulley tee, gas valve and
conduit offset.
GENERAL LIMITATIONS OF MECHANICAL VALVE NETWORK
Maximum of 20 corner pulleys per mechanical gas valve of any listed type in KP Manual
Maximum of 130 feet (39.6m) of cable per mechanical gas valve of any listed type in KP Manual
Maximum of I pulley tee per network (counts as one corner pulley for each mechanical gas valve)
Maximum of 1 conduit offset per network (must be located at pneumatic release module and before tee pulley
when chose)

ELECTRICAL GAS VALVE APPLICATIONS
110 VAC electrical gas valves may be used in place of the mechanical gas valves. The electric shut off valve
used with the Amerex KP Restaurant Fire Suppression System must be UL listed for use with natural gas or
propane, be held open by energizing an electric solenoid and be wired through a microswitch and manual
release relay. A qualified electrician must do any field wiring and connections involving the shut down of
electrical cooking equipment or an electric gas valve.

ELECTRIC GAS VALVE OPERATION
Power to the electric gas valve is run through the normally closed contact on a microswitch located in the
pneumatic release module (PRM) or mechanical release module (MRM) to the manual reset relay and from
the manual reset relay to the electric gas valve. In a normal (non fire) condition, current is allowed to flow to
the solenoid on the electric gas valve, holding the valve open. In a fire condition, when the release module
actuates the suppression system, the microswitch contacts will transfer, opening the normally closed contacts
in the manual reset relay, interrupting current to the gas valve and cause it to close.
Resetting the MRM or PRM and transferring the contacts back to a normal (normally closed) position will not
cause the electrical gas valve to open. The manual reset relay must reset before current will flow to the valve
and cause it to open. A loss in electrical power, even temporary or momentary, will require someone to
manually reset the relay before the electrical gas valve will open again.
