General Safety Information
Personnel should have a clear understanding of these
instructions and all applicable, current local and national
building and fire codes before installing this product.
NOTE
All service and maintenance on the fire suppression system
should be conducted by an authorized fire equipment
distributor. Do not tamper with fire suppression components
if not instructed to do so.
WARNING
To reduce the risk of fire, electric shock, or injury to
persons, observe the following:
• Use this product only in the manner intended by the manufacturer
(to cover domestic ranges used for domestic purposes).
• When cutting or drilling into wall or ceiling, do not damage
electrical wiring or other hidden utilities.
• Ducted exhaust fans must always be vented to the outdoors.
• Use only rigid, metal ductwork
• This unit must be properly grounded.
To reduce the risk of range top grease fire:
• Never leave the range unattended at high settings. Boil-overs
cause smoking and greasy spillovers that may ignite.
• Dense smoke from frying pans indicates cooking oil is near auto
ignition – turn the burner down or off.
• Always turn the hood fan ON when part of the cooking surface is
on
• Always make sure the hood grease filter is installed before cooking.
• Clean hood grease filter frequently. Do not allow grease to
accumulate on filter.
• Always use proper pan size. Use cookware appropriate for the size
of the surface element.
• Keep cooking areas clean and clear of combustible materials.
To reduce the risk of injury to persons in the event of a
range top grease fire, observe the following:*
• SMOTHER FLAMES with a close-fitting lid, cookie sheet, or metal
tray, then turn off the burner. BE CAREFUL TO PREVENT BURNS.
If the flames do not go out immediately, EVACUATE AND CALL
THE FIRE DEPARTMENT.
• NEVER PICK UP A FLAMING PAN. You may be burned.
• DO NOT USE WATER, including wet dishcloths or towels - violent
steam explosion will result.
* Based on “Kitchen Fire Safety Tips” published by NFPA.
AVERTISSEMENT
Pour réduire le risque d’incendie, de choc électrique ou
de blessure corporelle, respecter ce qui suit :
• Utiliser uniquement ce produit de la façon prévue par le fabricant
(pour couvrir les cuisinières domestiques utilisées à la maison).
• Lors de la découpe ou du perçage de murs ou plafonds, ne pas
endommager les câbles électriques et autres conduites masquées.
• Les caissons d’extraction à gaine d’évacuation doivent toujours
être évacués vers l’extérieur.
• Utiliser uniquement un réseau de gaine rigide, en métal.
• Cet appareil doit être bien raccordé à la terre.
Pour réduire le disque d’incendie de graisse sur le
dessus de la cuisinière :
• Ne jamais laisser la cuisinière sans surveillance à des réglages
élevés. Les débordements causent de la fumée et des
débordements de graisse qui peuvent s’enflammer.
• Une fumée dense provenant de poêles à frire indiquent que l’huile
à friture s’approche de son point d’inflammation spontanée. Régler
le bruleur plus bas ou l’éteindre.
• Toujours activer le ventilateur de la hotte lorsqu’une partie de la
surface de cuisson chauffe.
• Toujours s’assurer que le filtre de graisse de la hotte est installé
avant la cuisson.
• Nettoyer fréquemment la graisse du filtre de la hotte. Ne pas laisser
s’accumuler la graisse sur le filtre.
• Toujours utiliser la taille appropriée de poêle à frire. Utiliser une
batterie de cuisine proportionnelle à la surface de l’élément.
• Garder propre l’aire de cuisson et dégagée de toute matière
combustible.
Observer les points suivants pour réduire le risque
de blessures aux personnes advenant un incendie de
graisse sur le dessus de la cuisinière :*
• ÉTOUFFER LES FLAMMES à l’aide d’un couvercle ajusté,
d’une plaque à biscuits ou d’un plateau en métal, puis fermer le
brûleur. S’ASSURER D’ÉVITER DES BRÛLURES. Si les flammes
ne s’éteignent pas immédiatement, ÉVACUER LES LIEUX ET
APPELER LE SERVICE D’INCENDIE.
• NE JAMAIS SAISIR UNE POÊLE EN FLAMME. Vous pourriez vous
brûler.
• NE PAS UTILISER D’EAU, ni de linges à vaisselle ni de serviettes
mouillées car il pourrait se produire une violente explosion de
vapeur.

WARNING
Failure to affix the mounting bracket
to studs correctly can lead to
structural damage and/or serious
injury. The structural integrity of
the wall is the responsibility of the
contractor.
Hood Weight
30 inches 86 lbs.
36 inches 93 lbs.
AVERTISSEMENT
Si le support de fixation est mal posé
sur les montants, il peut y avoir des
dommages structuraux et/ou de
graves blessures. L’entrepreneur est
responsable de l’intégrité structurale
du mur.
It is recommended that before drywall is hung, all
electrical cables that need to be run within the wall
should be run through the wall to their corresponding
components. Mount the control j-box to line up with
the right corner of the hood mounting bracket and run
cables for these components into this box through the
grommets. Confirm all critical mounting points will need
to be secured through studs or utilize dry wall hangers.
Hood weight should be supported by at least two (2)
studs. Hood needs to be centered above the range and
within the height requirements shown. Make sure that
with integral fan – rear discharge configurations, the
studs and control j-box do not interfere with the rear
discharge duct.
After drywall is hung, affix mounting bracket to wall
using the necessary field provided fasteners through the
critical mounting points.

Ductwork (if applicable)
Running ductwork will be required for hoods configured for external fans. A small rectangular piece of duct spanning
the width of the wall will be required for integral fan – rear discharge configurations (discharging through the back
wall). Check the individual hood drawings to see what fan type is provided with your system.

All ductwork will need to be provided in the field. Installing ductwork must be done by qualified person(s) in
accordance with all applicable codes and standards, including fire-rated construction. All ductwork, per IMC Section
505 should be constructed of sheet metal, have smooth inner walls, be air tight, and be independent of all other
exhaust ductwork systems.
To minimize static pressure losses and promote adequate airflow, minimize duct run lengths where possible.
For external fan configurations, duct should be connected to the 8 inch collar adapter on the hood mounting bracket.
Transitions should be utilized to expand duct to duct size minimum requirements noted in table above.
Hood
1. Remove hood from crating. Remove the grease filter.
2. Carefully lift it onto the lower hood tabs on the wall mounting bracket.
2. While holding the hood up, hook the safety cable to the chain link on the mounting bracket and screw nut to close
the link. The hood is now in the service position.
3. To put the hood into operation position, lift the hood up, and one at a time re-hook the clamps and pull the clamps
tight until they lock. Make sure the safety bolt lever is located inside the notch in the hood mounting bracket. See
page 22 for pictures and more information.
4. When all construction is complete, remove protective plastic sheeting from hood stainless steel. Clean (using
alcohol and rag) and polish (using stainless steel polish) the hood. When cleaning or polishing, be sure to wipe
with the grain and not against it.
Fire Ready Hood 9
External Fan (if applicable)
External Fan – Inline
Install fan vertically or horizontally in ductwork running
between the unit and roof cap. Make sure the fan
installed with the airflow arrow on the side of the fan
directed away from the hood (to the outside).
For best results, use as few elbows or transitions as
possible. If necessary, long radius elbows or bends are
recommended.
To attach ductwork, use duct tape at inlet and outlet to
assure a good seal. If using fan clamps, attach clamps
and insert screws through clamp into inlet and outlet
flanges.
CAUTION
Use sheet metal screws to secure ductwork to inlet
and outlet. It is critical that the screw penetrate the
metal of the flange, but not so far as to bind the
impeller. It may be necessary to angle screws away
from impeller.
ATTENTION
Utiliser des vis autotaraudeuses pour fixer le réseau de

NOTE
Integral fan – front recirculating models shouldn’t have
to be calibrated, as these require no added ductwork.
Fan calibration is necessary for integral fan – rear
discharge and external fan configurations (both inline
and fan by others).
NOTE
To avoid poor hood performance, it is important for
the hood to be balanced for the designed CFM. For
NFPA 101 compliant models, 500 designed CFM is
required.

Press the “Balance Exhaust Fan” button, and fan will
turn on and ramp to full speed.
Once fan is on, connect one end of manometer to
plenum pressure port (1/8 inch MNPT barb located near
grease filter) and take reading. Adjust the max speed as
necessary to match the pressure with the corresponding
value on the screen (or reference the table below based
on your hood size and configuration).
For example, for a 36 inch, non-NFPA 101 compliant,
external fan – top discharge, inline fan configuration
model, to obtain the designed 300 CFM, we need the
plenum pressure reading to be 0.25 in. wc.

Unit Pre-Suppression Functions
The XRRS functions as a standard ventilation range
hood with the added capability to suppress stove top
fires.
Designed to use over a standard 30 and 36-inch
domestic range, the system relies on input from a
combination of sensors to control the fan and shutoff
power to the stove when the temperature reaches
preset points.
The fans and lights can be turned on and off using the
user interface. The range can also be unlocked via the
user interface. A password may be required to unlock
(turn on) the range. The range may be automatically
locked again after a time limit (default 2 hours) if the
hood system was configured for NFPA 101 compliance.
To comply with NFPA 101, this time limit cannot exceed
2 hours.
If the temperature reaches the cooking detection
temperature setpoint (default 115°F), the hood turns
the fan on (if not already on) and the fan speed control
buttons are disabled. The speed of the fan is no longer
controlled via the user, instead the fan is controlled via
the hood temperature.
If the temperature continues to climb, upon the
temperature reaching the high temperature setpoint
(default 180°F), the hood will immediately lock (shut off)
the range. An alarm will appear on the user interface
warning the user of the high temperature. The dry fire/
fault contacts at this point will switch state (see page 15
for terminal blocks and wiring information).
If the temperature continues to climb, upon reaching
approximately 216°F, the fire suppression system
will discharge, dispersing wet chemical on top of the
appliance and suppress the fire below.

System arming is typically performed by factory
authorized fire equipment distributor during startup.
Do not tamper with the fire suppression system after
the initial startup unless authorized to do so.
To arm the range, do the following:
1. Once hood and hood components are installed,
wired, and fan is balanced (if necessary), drop the
hood into the service position, (instructions on page
22) and turn on all breakers feeding the hood and
hood components.
2. Remove the black cover from the fire suppression
control board enclosure inside the hood (on left side
of hood if looking at the hood front face).

3. With the cylinder pull-pin still installed in the agent
tank (mounted beneath the fire suppression board),
and 9V battery installed on the fire suppression
control board, initiate a diagnostic test by press
and release of the “TEST” button (also on the fire
suppression board).
BACK WALL
4. The test should fail and issue six chirps, indicating
that the pull pin has not been removed from the tank.
If the result is a lesser number of chirps followed by
the series of six chirps, then some item other than
the pull pin has failed and the system should be
troubleshot before proceeding further (see Diagnostic
Failure Codes, page 25).
5. After troubleshooting, re-test until only the 6 chirp
diagnostic failure code occurs.
6. Verify that the fuel shut-off is powered (breaker is on)
and all burners on the range are off.
7. Remove wing screws that hold
the fire suppression control
board enclosure in place above
the wet chemical tank. Without
disconnecting any cables, slide
the control board assembly
towards the middle of the hood
and down so it’s next to the tank,
revealing the tank assembly.
8. Check and make sure the solenoid release latch
is engaged and holding the release latch up, then
remove the pull pin from the agent cylinder and insert
the pull pin in its socket on the PCU board.

10. The final step for verification is to turn on a range
burner, then momentarily push and release the
“TEST” button. If there are no failures detected, the
fire suppression board will run a shutoff sequence
(the alarm will sound for 10 seconds and shut off
fuel to the stove followed by a chirp every minute).
This allows complete verification of the system
function all the way to the fuel shut-off but without
the chemical agent dump. If the stove does not
shut-off (burner shuts off and begins to cool down),
additional troubleshooting is required.
11. Reset the CPU board by pressing the “RESET”
button and confirm the green indicator momentarily
lights up.
12. Make sure all burners are off, then unlock the range
via the user interface.

Fire Prevention Tips
If you must leave the kitchen when frying food, turn the
burner off or remove the pan from the burner until you
return.
In case of a grease fire:
NEVER attempt to move a pan of cooking grease that is
already on fire from the kitchen range.
NEVER attempt to extinguish a grease fire with water.
Instead, alert the other occupants and evacuate. Let the
fire suppression system installed in the hood extinguish
the range top fire. Wait at least 30 minutes after a
cooking fire has been extinguished before approaching
your range.

Service and Maintenance
Accessing Internal Components
NOTE
• All service on the fire suppression system should be
performed by authorized equipment distributor.
• Do not drop the unit into service position while
cooking on the range below.
WARNING
The hood is heavy. It is recommended to utilize
multiple people to drop the hood into the service
position; one person to support the hood while the
other disengages latches inside, as to prevent the
hood from causing injury.
ATTENTION
La hotte est pesante. Il est recommandé d’utiliser
plusieurs personnes pour abaisser la hotte en position
d’entretien, une personne supporte la hotte tandis que
l’autre dégage les loquets intérieurs pour empêcher la
hotte de blesser quelqu’un.
1. Pull down on

4. Now the hood is in its service position. Any service to
the fire system and interior components can be done
at this time.
5. To put the hood back into operation position, lift the
hood back up, and one at a time re-hook the clamps
and pull the clamps tight until they lock. Make sure
the safety bolt lever is located inside the notch in the
hood mounting bracket.
3. With both clamps released, release the safety bolt
lever simply by pulling the black handle down. Keep
upward pressure on the bottom of the front part of
the hood while doing this. After releasing the safety
bolt, the hood front will want to drop. Slowly lower the
front of the hood until the safety cable is tight.

Fire System Diagnostics
Pressing, then releasing the “TEST” button on the fire
system control board will start a diagnostic test, putting
the system into “test mode”. This is a way to verify
that the entire system is working properly and the fuel
shutoff function is working without discharging the fire
suppression wet chemical.
NOTE
The same tests that are performed after pressing and
releasing the “RESET” button are performed when
pressing and releasing the “TEST” button.
Upon entering test mode and failing any particular
test, a sequence of audible chirps will sound which
represent a failure code (as well as a quick flash of the
red indicator on the fire suppression control board).
If multiple tests fail then you will hear multiple series
of beeps with a pause in between each to identify
multiple failure codes. Upon failing any part of the test,
the control board will revert to a slowly flashing red
indicator. If all six tests pass, the unit will enter a shut
off sequence. (See next section, Fire System Shut Off
Sequence).

Chirps
1 Sensor 1 / Remote Pull
2 Sensor 2
3 Battery Voltage Low
4 Solenoid
5 Low Pressure
6 Pull-Pin
Corresponding Fire System Component Issue
Fire System Shut Off Sequence
A shut off sequence will cause:
1. 10 second audible alarm
2. Disconnect fuel from range
3. Following the 10 second audible alarm, the unit will
issue one chirp every minute to alert the owner that
the fire suppression system needs to be serviced.
Six items can cause a shut off sequence:
1. Low battery indication has persisted for at least 4.5
hours
2. A test sequence was executed successfully (see
Arming the System, page 18)
3. The pull-pin was removed from its socket while in fire
detect mode
4. An open circuit was detected on one of the fire
suppression temperature sensors while in fire detect
mode
5. An open circuit was detected on the solenoid while in
fire detect mode
6. Low pressure on tank cylinder detected while in fire
detect mode
Fire System Detect Mode
Upon pressing the “RESET” button on the fire
suppression control board (and passing successfully
passing all six diagnostic tests), the fire suppression
control board will display a solid green indicator for two
seconds, then the unit will enter into fire detect mode.
NOTE
Powering the fire suppression control board by
inserting the battery OR pressing and releasing the
“RESET” button will cause the same action.
During fire detect mode the fire suppression control
board will silently run all six diagnostic tests. If at any
time one of these test fails (with the exception of a
low battery), the fire suppression control board will
begin a shut off sequence (see above, “Fire System
Shut Off Sequence”). Upon a low battery, there will be
a short chirp to indicate that the battery needs to be
replaced, which occurs every minute. After 4.5 hours of
a low battery indication, the unit will enter the shut off
sequence.
During fire-detect mode, the main unit monitors two
sensors to detect high temperature indicating a fire.
If a fire is indicated, the fire system control board will
issue a fire alarm sequence (see page 26, “Fire Alarm
Sequence”).
Fire Ready Hood 25
Fire Alarm Sequence
A fire alarm sequence will only occur upon the detection
of extremely high hood temperatures (approximately
216°), or when the remote pull station is pulled (if
provided).
The fire alarm sequence causes:
1. Audible alarm
2. Fire system (wet chemical) discharge
3. Fuel shut off to disconnect fuel to the cooking
appliance (if not already shut off due to a high
temperature alarm).
NOTE
The fire alarm sequence can only occur when the fire
suppression control board is running in fire detect
mode.
NOTE
To mute the audible alarm, place the hood into
service position, and press “RESET” button on fire
suppression control board.
After Actuation
NOTE
A complete system inspection and servicing must be
done immediately following a kitchen range top fire.
Consult an authorized fire equipment company for
service or proper procedure.
NOTE
All service on the fire suppression system after
actuation should be performed by authorized
equipment distributor.
CAUTION
Before replacing the wet chemical, the tank, release
valve assembly, it is recommended to wear approved
type of eye protection and rubber gloves.
8. Flush out existing distribution assembly water to
remove residual wet chemical and blow dry.
9. Replace the extinguisher cylinder manifold O-ring
and reinstall manifold / siphon tube assembly into the
extinguisher cylinder (part of recharge kit).
10. Connect a nitrogen supply line to the ¼ inch male
quick connect fitting and pressurize to 100 PSI.
CAUTION
Do not use extinguisher cylinder gauge to determine
when the intended charge pressure has been reached.
AVERTISSEMENT
Ne pas utiliser le manomètre du cylindre extincteur
pour déterminer le moment où a été atteint la pression
de charge prévue.
11. Reinstall the extinguisher cylinder assembly in the
enclosure base.
12. Refer to the “Arming the System” section on page
18 to reactivate the system.
NOTE
Upon performing the fire system diagnostic test,
additional components may need to be replaced as
a result of the high temperatures and flames that
occurred during the fire. Replace these parts as
necessary (see “Parts” on page 29).
1. Shut off power to range (via building breaker).
2. Clean up all wet chemical using soap and warm
water with a sponge. Do not use vacuum cleaner.
3. Carefully drop the hood into the service position,
remove the fire suppression control board enclosure
cover, and remove the battery from the fire
suppression control board.
4. Disconnect the tank cylinder release valve terminal
wire connections from the fire suppression control
board.
5. Remove the extinguisher cylinder assembly from the
enclosure based by loosening the cylinder band.
6. Unscrew and remove the extinguisher cylinder
manifold / siphon tube assembly from the
extinguisher cylinder. Pour out any leftover wet
chemical in the cylinder.
7. Refill extinguisher cylinder with 4.9 lbs. of wet
chemical agent (part of recharge kit).
