from fuel combustion which can cause death or
serious illness and which are known to cause cancer,
birth defects, or other reproductive harm.
WARNING: IF THE INFORMATION IN
THIS MANUAL IS NOT FOLLOWED
EXACTLY, A FIRE OR EXPLOSION MAY
RESULT CAUSING PROPERTY DAMAGE,
PERSONAL INJURY, OR DEATH.
For example, benzene is a chemical which is part
of the gas supplied to the cooking product. It is
consumed in the flame during combustion.
However exposure to a small amount of benzene
is possible if a gas leak occurs. Formaldehyde
and soot are by-products of incomplete
combustion. Properly adjusted burners with a
bluish rather than yellow flame will minimize
incomplete combustion.

Gas Connection
The gas supply (service) line must be the same size or greater than the inlet line of the appliance. This oven uses a
1/2” (1.3 cm) ID NPT (Sch40) inlet. Sealant on all pipe joints must be resistive to LP gas.
1. MMaannuuaallsshhuutt--ooffffvvaallvvee::
This installer-supplied valve must be installed in the gas service line ahead of the appliance in the gas stream and in a
position where it can be reached quickly in the event of an emergency. IInnMMaassssaacchhuusseettttss::All gas products must be
installed by a “Massachusetts” licensed plumber or gasfitter.
2. PPrreessssuurreeRReegguullaattoorr::
a) All heavy-duty, commercial type cooking equipment must have a pressure regulator on the incoming service line for
safe and efficient operation, since service pressure may fluctuate with local demand. External regulators are not
required on this oven since a regulator is built into each unit at the factory. Under no condition bypass this built-in
regulator.
b) Any conversion required must be performed by your dealer or a qualified licensed plumber or gas service company.
Please provide the service person with this manual before work begins. (Gas conversions are the responsibility of the
dealer or end user).
c) This oven can be used with Natural or LP/Propane gas.
d) Manifold pressure should be checked with a manometer, natural gas requires 4.0” W.C.P. and LP gas requires 10.0”
W.C.P. Incoming line pressure upstream from the regulator must be 1” W.C.P. higher than the manifold pressure in
order to check the regulator. The regulator used on this oven can withstand a maximum input pressure of 1/2” PS
(14.0” W.C.P.). If the line pressure is in excess of that amount, a step down regulator will be required.
e) The appliance, its individual shut-off valve, and pressure regulator must be disconnected from the gas supply piping
system during any pressure testing of that system at pressures in excess of 1/2 psig (3.45 kPa)
f) The appliance must be isolated from the gas supply piping system by closing its individual manual shut off valve
during any pressure testing of the gas supply piping system at test pressures equal to or less than 1/2 psig (3.45 kPa)
3. RRiiggiiddCCoonnnneeccttiioonnss::
a) Incoming gas is brought from an intake pipe (not supplied) at the upper left corner of the unit to the pressure
regulator. The only connection necessary is from the service supply, through the shut-off valve (not supplied) to this
intake pipe (not supplied) to the regulator.
b) Double-check any installer-supplied intake pipes visually and/or blow them out with compressed air to clear any dirt
particles, threading chips, or other foreign matter before installing in service line. Those particles will clog orifices
when gas pressure is applied.
4. FFlleexxiibblleeCCoonnnneeccttiioonnss::
If the unit is to be installed with flexible coupling and/or quick-disconnect fittings, the installer must use a heavy-duty
agency design-certified flexible connector of at least 1/2” (1.3 cm) ID NPT (with suitable strain reliefs) incompliance with
ANSI Z21.41 and Z21.69. IInnCCaannaaddaa: CAN 1-6, 10-88 metal connectors for gas appliances and CAN 1-6.9 M79 quick
disconnect devices for use with gas fuel. IInnMMaassssaacchhuusseettttss::This appliance must be installed with a 36” (3-foot) long
flexible gas connector.
CAUTION: Before placing the oven into operation, always check for gas leaks with a soapy water solution or other
acceptable method. DDOONNOOTTUUSSEEAANNOOPPEENNFFLLAAMMEETTOOCCHHEECCKKFFOORRLLEEAAKKSS!!

Gas Bake Burner Adjustments for the Outdoor Oven
A properly adjusted burner should be stable and quiet. The flame should have sharp, well defined blue inner cone
with no yellow tipping. The flame should also be stable and uniform with no flames lifting off the burner ports.
1. Locate the air shutter and loosen the set screw that holds the air shutter in place.
2. Adjust the air shutter to obtain a blue flame with no yellow tipping that contacts the burner at the burner ports.
a. Open the air shutter gap to eliminate yellow tipping.
b. Close the air shutter gap to prevent a noisy flame that lifts off the burner.
3. Light the burners by rotating the thermostat to a baking temperature and pushing the ignitor button to light the
pilot. If the flame is not stable with a blue inner cone and no yellow tipping. Turn the burner off and repeat step 2.
4. Once a stable flame is achieved, tighten the air shutter set screws. The burner flame cone should be 1/2” long
when the air shutter is correctly adjusted. NOTE: Both air shutters should be set to the same opening.
5. Replace the bottom pan and racks.

IMPORTANT! CCoonnddiittiioonnsstthhaattccaauusseeooddoorrss::
1. Floating flames are lazy looking and do not have well defined cones. They are long, ill-defined, quiet flames that
sometimes lift completely off the ports and cause a strong and pungent odor.
2. Lifting flames are well defined, hard and noisy that lift completely off the ports.
3. An orifice that is out of line with the burner venturi.

Performance Checklist
The installer should carry out the following performance checks. Refer to instructions below.
1. Check oven ignition and bake burners.
2. Check air shutter adjustment; sharp blue flame,no yellow tipping, no sooting, no flame lifting.
3. Visually check tubular burner reignition to be sure both sides are relighting each time.
4. Check for gas leaks (odor) at all gas connections.
Final Preparation
1. Some stainless steel parts may have a plastic protective wrap which must be removed. The interior of the oven
should be washed thoroughly with hot, soapy water to remove film residues and any installation dust or debris
before being used for food preparation, then rinsed and wiped dry. Solutions stronger than soap and water are
rarely needed.
2. All stainless steel body parts should be wiped with hot, soapy water and with a liquid cleaner designed for this
material. If buildup occurs, do not use steel wool, abrasive cloths, cleaners, or powders! If it is necessary to scrape
stainless steel to remove encrusted materials, soak with hot, wet cloths to loosen the material, then use a wood or
nylon scraper. Do not use a metal knife, spatula, or any other metal tool to scrape stainless steel! Scratches are
almost impossible to remove.
Replacement Parts
Only authorized replacement parts may be used in performing service on the oven. Replacement parts are available
from factory authorized parts distributors. Contact Viking Range Corporation, [phone], for the nearest parts
distributor in your area.
