Introduction / S afety Precautions
Thank you for choosing your new Dynamic Cooking Systems Professional Restaurant Gas Tandoor. Our prod-
ucts are designed to be safe and reliable when properly cared for and used reasonably. Periodical inspections are
recommended by your service agency or dealer. Installation, maintenance, and repairs should be performed by your
local authorized service agency.
This equipment is for commercial use by trained professionals familiar with Tandoor cooking equipment. It is
the responsibility of the supervisor or equivalent person to ensure that users wear appropriate clothing and safety gear
before use. Please read all sections of this manual and retain for future reference.
Caution:
Should be used when operating your Tandoor, as some parts of the equipment, become very hot especial-
ly the top lip of the ceramic cone and could cause burns if touched accidentally. This equipment is not
intended for home use.
When properly cared for, your Tandoor will give safe, reliable service for many years. However extreme care must be
used since the Tandoor produces intense heat and can increase accident potential. When using this appliance basic
safety practices must be followed, including the following:
●Begin by insuring proper installation and servicing. Follow the installation instructions provided with this product.
Have you Tandoor installed by a qualified technician. Have the installer show you where the gas supply shut off valve is
located so that you know where to shut off the gas to the Tandoor. If you smell gas, your installer has not done a prop-
er job of checking for leaks. If the connections are not perfectly seated and tightened, you can have a small leak and
therefore a faint gas smell.
●This Tandoor must be installed under a proper overhead vent hood.
●Keep appliance free and clear of any obstructions, either to the combustion ventilation pathway or the service and
maintenance access way.
●Keep this appliance free and clear of all combustible materials.
●Be certain that specified safe and proper distances are maintained between the Tandoor and combustible wall
surfaces and counters.

Pre-Installation
Important:
Safe and satisfactory operation of your equipment depends on its proper installation. Installation must conform
to local codes, or in the absence of local codes, with the National Fuel Gas Code, ANSI Z223.1-1988 (or latest edition).
The Canadian CAN/CGA-B149.1 Natural Gas Installation code, and CAN / CGA B149.2 Propane installation code.
NOTE: Installation of any gas fired equipment should be perf0rmed by a licensed plumber. A manual gas shut
off valve must be installed on the gas supply line ahead of the appliance(s) for safety and ease of
future service.
CLEARANCES
The appliance area must be kept free and clear of all combustibles. Adequate clearance must be provided for
air openings into the combustion chamber and for proper air supply. This unit is design certified for the following instal-
lations:
1. Intended for
ootthheerr
use than household use.
2. For installation on a non-combustible floor when equipped with the factory supplied 6” adjustable legs or 5”cast-
ers.
3. With minimum clearance of 6” side and 6”rear for combustible construction.
STANDARDS
Installation must be planned in accordance with all applicable state and local codes, taking into account the fol-
lowing standards (or latest edition).
●Ventilating Hood - ANSI/NFPA 96-1984 ●Fire Detection Thermostat- ANSI/NFPA 72B-1979
●Fire Extinguisher (CO2) - ANSI/NFPA 126-1985
Installation in the United States must meet: ANSI Z88.13 1991 (or latest edition) American Gas Association, and
NFPA Standards #96 and #21-1 National Fire Protection Association.
AIR SUPPLY & VENTILATION
The area around the appliance must be kept clear to avoid any obstructions to the flow of combustion and venti-
lation air as well as for ease of maintenance, service, and proper appliance operation. Keep clearance for air openings
into the combustion chamber and adequate air supply. Means must be provided to exhaust combustion wastes to the
outside of the building.
Air movement should be checked during installation. Strong exhaust fans in this hood or in the overall air condi-
tioning system can produce a slight air draft in the room, which can interfere with pilot or burner performance. If pilot or
burner problem persist, make-up air openings of baffles may have to be provided in the room.
Filters and drip troughs should be part of any industrial hood, but consult local codes before constructing and
installing any hood. The duct system, the exhaust hood, and the filter bank must be cleaned on a regular basis and kept
free of grease.
ALTITUDE
The Tandoor input rating (BTU/HR) is for elevations up to 2,000 feet. For elevations above 2,000 feet, the rating
should be reduced four percent for each additional 1,000 feet above sea level. The correct orifices are installed if the
operating altitude is known at the time of sale.

UNPACKING
Check that the container is upright. Use outward prying no hammering to remove the carton. Check the
Tandoor for visible damage. If such damage has occurred, do not refuse shipment, but contact the carrier and file the
appropriate freight claims. Do not contact the factory, as responsibility for shipping damage is between the carrier and
dealer or end user. Remove, unwrap, and temporarily set aside any accessories shipped with the Tandoor.
POSITIONING
Do not push against the edges of the unit in an attempt to adjust its position. Lift it slightly and place it where it
is to be installed. Although all metal parts are deburred during manufacture protective gloves are recommended when
ever positioning or moving unit. Accidents could occur if the Tandoor should move suddenly while being pushed into
position by hand. Pushing a unit (rather than using a lift jack) also increases the probability of bending the leg spindles
or the internal coupling connectors.
LEVELING
A carpenter’s spirit level should be placed across the top of the Tandoor and the unit leveled both front to back
and side to side. If it’s not level, burner combustion may be erratic or the unit may not function efficiently. If the floor is
level and smooth, level the unit with the screw thread of the legs; adjust the high corner and measure with the spirit
level. If the floor is uneven or has a decided slope, level the unit with a metal shim; the adjustment required may
exceed the thread available in the leg, and / or a castered line-up may not return exactly to the same position after
being moved, requiring re-leveling after each move.
GAS CONNECTION
The gas supply (service) line must be the same size or greater than the inlet line of the appliance. The Tandoor
uses a 3/4” NPT inlet, however, the gas supply lines must be sized to accommodate all the gas fired equipment that
may be connected to that supply. Consult your contractor, gas company, supplier, or other recognized authorities.
Sealant on all pipe joints must be resistive to propane gas. When using thread compound on gas piping, use very small
amounts and only on male threads. Use a pipe thread compound that is not affected by the chemical action of L.P.
gases. Do not apply pipe thread compound to the first two pipe threads. This will prevent clogging of the burner ori-
fices and the control valve.
MANUAL SHUT-OFF VALVE
Supply shut-off valve must be installed on the gas service line ahead of the appliance in the gas stream to shut
off supply in the event of an emergency.

PRESSURE REGULATING
The Tandoor and its individual shut-off valve must be disconnected from the gas supply piping system during
any pressure testing of that system at pressures in excess of 1/2 psig.
The Tandoor 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 at pressures equal or less than 1/2 psig.
Tandoor must have a pressure regulator on the incoming service line for safe and efficient operations.
Regulators installed must be listed by a nationally recognized testing agency. Line service pressure may fluctuate with
local demand. If the incoming pressure is in excess of 1/2 psig. A step down regulator will be required. Minimum
incoming pressure must be 7”W.C. for natural and 11”W.C. for propane.
Manifold pressure should be checked with a manometer. Natural gas units require 6”W.C. and propane units
require 1o” W.C. Double check the arrow forged into the bottom of the regulator body which shows gas flow direction.
It should point downstream towards the appliance. The air vent cap is also part of the regulator and should not be
removed. The pressure regulator installed must be listed by a nationally recognized testing agency. If the vent line from
the gas appliance regulator is used, it should be installed to the outdoors in accordance with local codes or in the
absence of local codes, with the National Fuel Gas Code, ANSI z223.1-1988.
Regulators can be adjusted in the field, but it is not recommended that they be tampered with unless the part is
known to be out of adjustment or serious pressure fluctuations are found to exist and can be solved no other way. Any
adjustment to regulators must be made by qualified service personnel with the proper test equipment.
RATING PLATE
The Tandoor can be connected to either natural or propane gas, depending on the customers ordering instruc-
tions. Be sure the unit gas type matches the supply gas type. Gas type will be located on the rating plate.
The rating plate is attached to the inside of the lower front panel. Information on this plate includes the model
and serial numbers. This data is essential for proper identification when communicating with the factory about a unit or
requesting special parts or information. Other information on this plate is the BTU/HR input of the burners, outlet gas
pressure in inches W.C., and whether the unit is orificed for natural or propane gas.
The Tandoor can be connected to either natural or propane gas, depending on the customers ordering. Be sure
the unit gas type matches the supply gas type. The Tandoor is field convertible between natural and propane gas.
Contact customer service at [phone] for conversion kit and conversion instructions.
Caution: All connections must be sealed with a joint compound suitable for L.P. gas, and all connec-
tions must be tested with a soapy solution before lighting any pilots. DO NOT use an open flame to
check for leaks. Putting an open flame beside a new connection is not only dangerous, but will often
miss small leaks that a soapy solution would find.
FLEXIBLE COUPLING, CONNECTORS, & CASTERS
If the unit is to be installed with flexible coupling and / or quick disconnect fittings, the installer must use a
heavy duty, commercial flexible connector at least 3/4”NPT (with suitable strain relief) in compliance with the standard
for connectors for movable gas appliances, ANSI Z21.69-1987 and Addenda, Z2.169a-1989 (or latest edition) or connec-
tors for movable appliances, CAN/CGA-6.16 (or latest edition) and a quick disconnect device must comply with the stan-
dard for quick disconnect devices for use with gas fuel, ANSI Z21.41-1989 (or latest edition) or quick disconnect devices
for use with gas fuel, CAN1-6.9 (or latest edition).

Initial Start-up / Operation
PLACEMENT OF LAVA ROCK
Place a layer of lava rock on the stainless steel pan located directly above the burners.
PILOT & MAIN BURNERS
All Tandoors are tested and adjusted before leaving the factory, effectively matching them to sea level condi-
tions. Adjustments to assure proper operation may be necessary on installation to meet local conditions; low gas pres-
sure, differences in altitude, variations in gas characteristics, possible problems caused by rough handling or vibration
during shipment, and are to be performed only by qualified service personnel. These are the responsibilities of the cus-
tomer and/or dealer and are not covered by Dynamic Cooking Systems Inc.
The Tandoor utilizes a standing pilot to ignite the main burners. Both the pilot and main burner gas supply are
fed through a thermomagnetic safety valve. Proof of pilot through the use of a thermocouple is required for main gas
supply to open. To gain access to the safety valve and pilot open the hinged lower front panel. The pilot is located
between the two burners.
LIGHTING THE PILOT
1) Turn OFF the two main burner valves located on the front of the Tandoor.
2) Open the manual shut off valve in the incoming service line.
3) Open the hinged lower front panel.
4) Depress and hold the red button on the safety and apply a lit match or taper to the pilot burner. Hold this
button in until the pilot stays lit when it is released. This may take a minute or longer.
5) If the pilot does not stay lit, depress the red button on the safety valve and relight the pilot, holding the red
button in longer before releasing. It may be necessary to relight the pilot several times until the lines are
purged of any trapped air and a constant gas flow is established.
LIGHTING MAIN BURNERS
Once the pilot burner flame is established either or both of the main burners can be lit by turning on the burner
valves located on the front panel of the Tandoor.
Warning: When lighting the pilots and checking for burner performance keep your face away from
the burners. The burner may light with a “POP”and could flashback and cause facial
burns.
Caution: If the pilot and main burner go out, the Tandoor MUST be left completely shut down at
least 5 minutes before lighting.
SHUT DOWN
Nightly shut down turn OFF both main burner valves located on the front panel of the Gas Tandoor. To com-
pletely shut down turn OFF both burner valves located on the front panel of the Tandoor and turn OFF the manual shut
off valve in the incoming service line.

Cleaning and Maintenance
GENERAL
New units are wiped clean at the factory to remove any visible signs of dirt, oil, grease remaining from the man-
ufacturing process. They should be washed thoroughly with hot soapy water to remove any installation dust or debris
before being used for food preparation. Also wash any accessories shipped with the Tandoor.
Any piece of equipment works better and last longer when maintained properly and kept clean. Tandoor is no
exception. The Tandoor must be kept clean during the working day and thoroughly cleaned at the end of each day.
DAILY CLEANING
During the day, all stainless steel body parts should be wiped regularly with hot soapy water. At the end of
each day, a liquid cleaner designed for this material should be used. Remove and thoroughly clean drip pan.
The Tandoor should be checked and adjusted periodically by a qualified service personnel as part of a regular
kitchen maintenance program. This service should include the removal of any built up grease in control boxes.
CAUTION: Do not use steel wool, abrasives clothes, cleansers, or powders. If it is necessary to scrape stain-
less steel to remove encrusted material, soak the area with hot 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 made by these types of instruments are difficult to remove.
REPLACING PARTS
The following should be performed by a qualified service technician.

Troub les hooting
These troubleshooting procedures must be carried out only by a factory authorized agency for warranty repair.
The problems and possible solutions given below cover those most commonly encountered.
PILOT BURNER MALFUNCTION
Pilot will not ignite; no evidence of gas at pilot burner:
●Check that the gas valve is open and gas is present at the valve.
●Check pilot burner adjustment. Adjust the pilot flame to extend above the top of the pilot. Pilot adjustment
screw is located on the front panel between the two burner valves.
●Remove pilot gas supply line and check for dirt. Blow out if necessary and reinstall.
●Check pilot burner orifice for dirt.
Pilot burner ignites but will not remain lit when red button is released:
●Check that the thermocouple lead is firmly screwed into the safety valve.
●Remove end of thermocouple lead from safety valve and clean with fine sandpaper.
●If thermocouple is defective or damaged, replace thermocouple.
●Pilot flame may be too high or too low. Adjust flame by turning pilot flow adjustment screw.
Pilot flame of proper size but unstable. Flame wavers and does not envelop the thermocouple completely at all
times:
●Check for drafts which might be caused by air conditioning equipment or make-up air apparatus. Turn these
“OFF”and recheck the pilot.
MAIN BURNER MALFUNCTIONS.
Main burner will not come “ON”, no gas present at main burner:
●Check that the gas valve is open.
●Check that pilot is ignited and is operating properly.
●The safety valve may be defective. Replace if necessary.
Main burner flames are small and appear lazy, Tandoor is not heating up quickly.
●Check gas pressure at the pressure tap on the manifold pipe located behind the front panel. Use a standard
water type U-Gauge manometer. With the burners in operation, the manifold pressure should be 6”W.C. natural gas
and 10”W.C. on propane gas. If not, unscrew the cover of the pressure regulator adjustment. Use a screwdriver to turn
adjusting screw clockwise to increase gas pressure to burner, counter-clockwise to decrease the pressure. Replace
cover and plug.
