This oven has been tested and certified for use on gas systems that do
not exceed 1/2 psi (3.45kPa) or pressure. If the piping system is tested at a
pressure higher than 1/2 psi (3.45kPa),this oven should be isolated from the
supply by disconnecting it. If the piping system is tested at a pressure lower
than or equal to 1/2 psi (3.45kPa),this oven should be isolated from the
supply by shutting off the manual shut off valve located on the front panel.
ELECTRICAL CONNECTIONS
Your oven is supplied for connection to a 115 volt, single phase
grounded circuit. The electric motor, oven lights, indicator lights and control
circuits are connected through a seven-foot electric supply cord found at
the rear of the oven.
Before making any connections to these units, check the rating plate to
assure that the voltage and phase of the oven is compatible with the electrical
supply. When installing, all ovens must be electrically grounded in accordance
with local codes, or in the absence of local codes, with the National Electrical

-13 -
Code, ANSI/NFPA70 (in Canada-CSA Std.C22.2).Wiring diagrams are located in
the control compartment area of the oven. Standard wiring schematics are also
provided with this manual.
WARNING：This appliance is equipped with a three-prong (grounding)
plug for your protection against shock hazard and should be plugged directly
into a properly grounder three-prong receptacle. DO NOT cut or otherwise
remove the grounding prong from this plug.
VENTILATION
Proper ventilation is very important for the proper function of your oven. A
good ventilation system will allow the oven to function properly as well as
remove unwanted vapors and products of combustion. Not venting the ovens
properly can result in unsatisfactory baking results as well as the possibility of
damaging your oven. To keep your warranty in force, a proper ventilation
system must be employed, either direct vented or under a canopy;
Warning! Use soap water or testing instrument to test whether
piping joint leaks or not before using, and forbid using an open flame to
test!
After installing completely, you should check gas supply pressure. Use
a pressure gauge which is equipped with liquid (such as U-type
pressure gauge, the minimum value is 0.1mbar) or a digital pressure
gauge to test. Steps are as following:
●After opening the door, loosen the four
screws that hold the lower panel, pull

-14 -
the panel out, and the pressure test
point is on the right.
●Remove needle type pressure joint screw
arbor (Fig.1), then slip rubber tube of
pressure gauge over needle type pressure
joint;
●Start the equipment in accordance with the
instructions, measuring gas supply pressure
(dynamic pressure) in the work state;
●Access to the equipment if measured data Figure 1
within the limits of Table 1, otherwise,
you will need to adjust gas pressure
regulating valve or contact gas supplier
to bargain;
●Unplug pressure gauge after you accomplish pressure testing, then
install needle type pressure joint screw arbor.
Important: must screw joint screw arbor, to prevent gas escape!
It’s very important to debug the new stove. Through the
comprehensive system test of equipment, we can ensure function and
safety performance of products. Discovering any potential problems
before use (such as equipment’s placement, ventilation, operation, etc),
can avoid costly losses.
7. Safety Notices and Precautions
Warning! For your safety, do not place petrol and other flammables
nearby. Please keep clean and free of flammables surroundings. (Read
ANSI Z83.14B, 1991 for reference)
Warning! Any erroneous installation, adjustment and refit may
cause property damage or personal injury and maintenance failure.
Read the instructions carefully before installation and using.

Programming and Operating Instructions
Models with the controller enable the oven to cook food at a specified
temperature for a specified time period, than enter an optional hold mode,. The
hold mode holds food at a specified temperature for a specified period of time.
When the power switch is in the ON position the oven will be in one of two
modes:
1. Cook Mode : In this mode the oven operates at a specified temperature
and the fan runs continuously, unless the cycle option is selected. In cycle
mode the fan runs for 30 seconds and is off for 30 seconds. This cycle
continues during the specified cook time.
2. Hold Mode : In this mode the oven operates at a specified hold temperature,
however the fan only runs when the burners are on . If the fan mode switch is in
the COOL position the fan will run continuously in the Hold mode.
To Program Cook Mode do the following:
1. Turn the power switch ON. The power switch is located in the middle of the
Control Panel.
