INSTALLATION Continued
Ventilation and Air Supply
One of the most important considerations is ventilation.
The fryer must be installed so that products of combustions
are removed efficiently, but so that the kitchen ventilation
system does not produce drafts that interfere with proper
burner operation. The fryer flue opening must NOT be placed
close to the intake of the exhaust fan.
The fryer must never have its flue extended in a chimney
fashion. This changes the combustion characteristics of the
fryer. This will cause the fryer to be slow to recover, frequently
cause delayed ignition, and sometimes cause pilot outage.
The ideal method of ventilating a fryer is the use of a
properly designed canopy which should extend six inches
(6”) (152mm)beyond all sides of the appliance and six feet
(6’) six inches (6”) (1981mm) from the floor.
Many operators do not realize that the finest ventilation
system will break down when it is not maintained properly.
The duct system, the hood, and the filter bank must be
cleaned on a regular basis and kept free of grease.
Adequate distances must be maintained from the flue outlet
of the fryer to the lower edge of the filter bank. Filters should
never be installed in the horizontal position. They should be
installed at an angle of 45 degrees, and a drip tray should be
located beneath the lowest edge of the filter. NFPA Standard
No.96 states that “A Minimum distance of 18” (457mm)
should be maintained between the flue outlet and the lower
edge of the grease filter.” We recommend that the MINIMUM
DISTANCE BE 24” (610mm) FROM THE FLUE OUTLET TO
THE BOTTOM EDGE OF THE FILTER WHEN THE APPLIANCE
CONSUMES MORE THAN 120,000 B.T.U. PER HOUR.
A strong exhaust fan will create a vacuum in the room, for an
exhaust system vent to work properly, replacement air must
enter the room in which the vent is located.
All gas burners and pilots need sufficient air to operate and
large objects should not be placed in front of this fryer which
would obstruct the air flow through the front. A minimum of
24” (610mm) should be provided at the front of the unit for
servicing and proper operation. Air for combustion enters
the unit below the cabinet at the base. Do not place anything
around the base or under the fryer.
Assembly Of Battery
All heavy duty batteries equipment is aligned and fitted at
the factory, from left to right and must be installed in this
order. There is a diagram provided with every heavy duty
battery. All 35M/MST Fryers and 70M/MST Fryers may be
installed to battery with other GARLAND 40 Series Ranges,
sharing common manifold connections.
A. All such units should be placed in their respective battery
position. Detach valve panels to prevent damage,
remove them from the area where the battery is being
assembled.
B. Level each unit (if a range, to the oven rack) by adjusting
the six inch (6”/152mm) legs, or where legs are not used,
adjust level with shims. Readjust legs, if required.
C. Connect units together by mating the unions at each
end of the manifold. (Adjoining units must have
matching unions, unless the union parts are of the
same specifications, a leak proof connection cannot be
assured.) Hand tighten unions at this point.
D. The units should be fastened at the rear by inserting 5/16”
bolts through the holes provided at the rear of the burner
box sides. Install washer and nut and hand tighten. Be
sure of proper unit alignment in the battery before final
tightening of these bolts or unions. Improper tightening
will cause “fanning” or “bowing” of batteried units.
The final tightening of the union should be accomplished
by using a suitable spanner wrench. If such a wrench
is not available, the GARLAND union collar has special
ridges, and a cold chisel can be driven against these
ridges to properly seat and seal the union.
E. The manifold of this unit or the manifold of which is
a part of must be equipped with a certified pressure
regulator suitable for battery application and adjustable
for an outlet pressure at the manifold as specified on the
rating place
