General Description

Halton’s MM1 Series hood is designed to efficiently capture and remove the grease, smoke, and
other effluents generated when cooking with pizza ovens. The hood is designed to rest on top of the
pizza oven which provides an operational advantage of capturing the grease, smoke and other
effluents directly above the pizza oven outlets. By localizing the capture area the hood can
efficiently capture and effectively eliminate convective heat spillage to the store.

System Capabilities

The hood system is ETL listed in both the United States and Canada for use with the Middleby­Marshall PS360G, 536, 540, 555, 570, 636, 640 and 670 model ovens, both gas and electric. The
hood can be used with single, double or triple-stack configurations at the design exhaust airflows
shown on the previous page. Optional side skirts can also be utilized with all oven configurations
(single, double and triple stack) to reduce the required exhaust airflow. An optional eyebrow over the

front loading window is available when desired or required by local codes.

Model MM1 INSTALLATION INSTRUCTIONS

1) Inspect the crating carefully. If there are signs of damage, call the freight carrier
before uncrating the units. Carefully uncrate the units.

** Important note **

Do not leave units out in the weather for an extended time period. The protective PVC
around the hood will become very difficult to remove if left exposed to the weather
conditions for a long period of time.

2) Position the hood near the actual installation site and carefully remove the crating
material.

3) Locate the mounting channels on the top of the uppermost oven. The channels
should be fastened to the top of the oven with machine screws. Threaded
inserts are installed in the top of the oven which will locate the channels
approximately 1.5” from the front of the oven and about 3” in from each end.
Match the mounting holes in the channel to the threaded inserts and tighten
securely. (See reference drawing)

4) Place the hood on top of the oven with the base of each pod resting in the
channels attached in the previous step. The stainless steel fascia piece
between the pods should be at the front of the hood. The two hat channel
braces between the pods should be at the back of the oven.

4) Make sure grease filters and grease cups are installed in place before start-up.

5) Until the unit is placed into service, protect the outer surface from being scratched

under normal job site conditions.

Installation of Mounting Channels

6) Side skirts, when desired, may be installed on both pods or are sometimes only

required on the intake end of the oven. See the job specific submittal drawings or
cut sheets for guidance on the locations and number of the side skirts. Side skirts
are installed, if desired, by fastening the upper edges of the side skirt to the lower
edges of the hood pod end walls where holes are provided for this purpose. Tabs
are provided along the flange which runs down the oven body which allows the
side skirt to be attached to the oven at predetermined points. Threaded inserts
have been installed at these points on the oven to allow the side skirt to fasten to
the oven. The screw(s) are installed into the threaded inserts, through the slotted
tabs, and tightened to hold the side skirt in position.

FIRE SUPPRESSION SYSTEM

The MM1 hood may be ordered pre-piped with a fire suppression system. Local codes or
a desire for enhanced fire safety may dictate the inclusion of fire protection in the hood.
The hood, if ordered pre-piped, will come with the detector bracket and fire protection
nozzles installed in the exhaust plenum of both hood pods to cover the requirements of
the duct protection and exhaust plenum protection. The local Ansul fire system installer
must supply the distribution piping, Ansul Automan and suppressant tanks, detector
conduit and wire rope runs, fusible links, remote pull station, Ansulex liquid fire
suppressant and all other supplies to complete the fire system installation. If appliance
protection is required the local Ansul installer must also design and install the distribution
piping and nozzles for this requirement. The side skirts on the rear of the hood require
holes to be punched to allow access for the appliance protection distribution piping. This
work must be performed by the Ansul system installer. The illustrations below depict the
typical layout for an MM1 hood fire system. The pre-pipe components supplied by Halton
are shown in solid lines and the components supplied by others are shown in dashed
lines. The complete fire system must satisfy the requirements of the National Fire
Protection Association (NFPA), Underwriters Laboratories Standard 300 and all local
codes and Authorities Having Jurisdiction.

1) After installation is complete, it will be necessary to check and balance the airflows.

2) After the system has been placed into service and the balancing of airflows has been
accomplished, a final inspection should be made. Check for unusual noises, excess
exhaust or supply rates and general operations.

HOOD MAINTENANCE

OPERATION OF SYSTEM

1) Clean the hood canopy inside and out as needed with mild soap and water. Never
use harsh or abrasive cleaners on Stainless Steel or Painted surfaces.

2) Clean the filters and grease cup(s) daily, first washing by hand, and then placing them

into a dishwasher or by steam cleaning.

** Handle the Grease filters carefully **

WARRANTY

Halton Company warrants all MM1 hoods for a period of 12 months from date of
shipment to be without defects in workmanship and material. Omissions or defects
will be re- placed or repaired at Halton’s option. Halton will not accept labor charges

GENERAL INSTALLATION

Upon receipt of the Halton hood, inspect it immediately for any shipping damage and
notify carrier immediately if damage is found. Halton will not accept responsibility for any
shipping damage, but will assist with getting a claim filed if needed.

There are no instructions contained within this manual for installation or maintenance of
fan packages. See appropriate manufacturer’s manual for detailed instructions.

It is the responsibility of the installing contractor to see that the system installation is
completed in accordance with the project plans and specifications and that it meets all
specific requirements of local code officials. The local authority having jurisdiction could
overrule some of the installation details written in this manual. The installation shall be
in accordance with NFPA-96. All electrical systems shall be installed following local and
national codes.

It is very important that the system be turned over to the owner in the best condition pos­sible. The owner and/or operator should be instructed in the proper operation, care and
maintenance of the system.

If questions or complications should arise during the installation of the Halton hood
that cannot be solved using the instructions, please contact Halton office at 1-800-442-

5866.

EXHAUST AIRFLOWS

Because the exhaust airflows rates were established under controlled laboratory condi­tions, please see submittal drawings or contact the manufacturer for exhaust air flow
rates.
