INTRODUCTION
The high performance Market Forge Purr-fect Height Steam Shell Griddle Convection Oven Combo creates a new class of
steam cooking equipment. More heat is delivered per square inch than any other griddle and assures food safety. Additionally, steam is injected into the cooking compartments. This technology allows the food to be cooked from both sides, dramatically decreasing cooking times and allowing for broader menu items. These items include seafood, stir-fry, vegetables
and pork. With the glass window in the cooking lids, food can be observed while cooking.
INSTALLATION
GENERAL: Once the unit is installed it must be elec-
trically grounded and comply with local codes, or in the
absence of codes with the National Electrical Code ANSI
NFPA 70-1999. Installation in Canada must comply with
CSA Standard C22. NO. 109-M1987.
CLEARANCES: Allow at least a three in clearance between the back of the unit and any wall obstruction for
proper ventilation, room for plumbing and electrical connections. The ventilation opening on the back of the griddle must have access to cool air. Griddle needs to be placed
on a level surface to provided ultimate performance. A nonlevel unit could lead to heating element damage.
THIS PROCEDURES SHOULD BE FOLLOWED BY
QUALIFIED PERSONNEL ONLY. DAMAGE WILL
VOID WARRANTY!
All griddles are shipped with a de-scaling filter. Installing
the de-scaling filter according to the manufacturers instructions. See manual included with de-scaler. If de-scaler filter
is not included with the griddle when shipped, contact the
factory. Failure to use approved de-scaler system may void
warranty.
TO INSTALL:
Unpack carefully. Remember to report any damage to
1.
the freight company immediately.
Do not remove any tags or labels until the unit is in-
2.
stalled and working properly.
Set the unit on a level floor.
3.
Install lids as shown in figures 1 through 3.
4.
CAUTION:
Glass Doors!
Use extra caution
when unpacking.
Figure 1
Lift lid with both
hands and set para llel to back of unit.
Figure 2
Figure 3
Once lid is securely
seated under counterweight bar, lower lid
slowly parallel to surface
of griddle.
WATER CONNECTION:

OPERATION
GRIDDLE CLEANING AND SEASONING:
1. Seasoning is a process to protect the griddle from rusting and prevent foods from sticking to the surface
during cooking.
2. Use only a small amount of vegetable oil, such as Wesson. Spread is around evenly (avoiding Corners)
while heating.
3. Pour salt over griddle surface and rub in circular motions over entire griddle surface with a handle and
grill screen.
4. When the oil begins to smoke, turn off griddle and squeegee off salt and oil. Let griddle cool for a 30
minute period.
5. Repeat the process one of two more times.
6. Re-season as needed.
7. Do not use water, soaps or griddle cleaners to clean griddle surface. If you do, you must re-season griddle
surface. In between normal cooking operation scrape griddle with a plastic scraper to keep clean. DO
NOT THROW COLD WATER ON A HOT GRIDDLE! it may cause the griddle surface to warp.

CLEANING / PREVENTIVE MAINTENANCE
Cleaning procedures for griddle and stainless steel surfaces:
1. Suggested tools: Rubber Squeegee, rubber or plastic
scrapers, plastic wool, cloth, griddle cleaner and sanitizer.
2. Precautions: Before any cleaning, reduce temperature to
325oF.
3. Remove glass lids and divider. CAUTION: LIDS AND
DIVIDER MAY BE HOT!
4. Clean all food contact surfaces as soon as possible after
use, preferably while the griddle is still hot. Scrape
griddle with a spatula to remove loose food debris. BE
CAREFUL NOT TO SCRAPE THE GRIDDLE SURFACE WITH METAL UTENSILS.
5. Prepare a solution of griddle cleaner as instructed by the
supplier, clean the griddle surface thoroughly.
6. To remove materials stuck to the surface use a brush,
sponge, cloth, rubber scraper, plastic scraper or plastic
wool along with the detergent solution. To minimize the
effort required in washing let the detergent solution sit
on the unit and soak into the residue or heat the detergent
briefly. DO NOT use any abrasive materials or metal
implements that might scratch the surface. Scratches
make the surface hard to clean and provide places for
bacteria to grow. DO NOT use steel wool which may
leave particles imbedded in the surface, causing corrosion and pitting.
7. Rinse the griddle thoroughly with clean water.
8. When the equipment needs to be sanitized, use a sanitizing solution. Contact our factory to ask which sanitizing
solution is best. Follow the instructions on the sanitation solution bottle and apply to the unit after it has been
cleaned and drained. Rinse off the sanitizing solution
thoroughly with clean water.
9. Turn the griddle on and allow surface to heat up enough
to dry thoroughly. Once dry, coat the griddle surface
with a thin layer of liquid shortening.
Cleaning the glass lids:
A. During daily cooking, the glass lid window can be
cleaned using a rubber squeegee and a wet towel.
B. The lids can be removed and placed into the dish-
washer for easily cleaning.

2600 PHE OVEN
YOUR ENERGY EFFICIENT CONVECTION OVEN
The Purr-fect Height Convection Oven is electrically
powered, high capacity ovens featuring high energy
efficiency. These ovens are designed to radically cut
power consumption, delivering the cooking power
of a 16 KW oven from only 11 KW’s of energy input. Improvement of energy use is made possible by
a carefully designed insulating system which keeps
heat inside the oven longer.
A convector fan distributes heat uniformly through-
HOW THE OVEN OPERATES
The Purr-fect Height Convection Oven operates by
use of two simple controls-a power switch for turning on the fan motor and control circuit, and a thermostat for setting the oven temperature. The oven
is otherwise automatic. A thermostat maintains oven
temperature by cycling heating elements on and
off, with temperature fluctuating no more than 20°F
from the setting. Uniform distribution of heat within
the oven is assured by continuous operation of a convector fan.
out the oven interior, for fast even roasting and
baking.
Like all Market Forge products, our ovens are built
to the highest standards of workmanship, employing only the finest materials and components Of
course, Power Saver II ovens are fully approved by
UL, UL Sanitation, and other official testing authorities.
A 60-minute and Constant Heat timer serves as an
aid in using the oven, when the timer expires the
heating elements shut off. To prevent unnecessary
loss of heat when the doors are opened, a interlock
switch stops fan operation whenever the rightside door is opened. Should the operator wish to
cool the oven, opening just the left- side door will
quickly ventilate the oven interior.
