q Allow a minimum of 4-inches (102mm) from the
right side of the oven to allow the door to open to at
least a 90° angle. Fully opened, the door will extend
up to a 225° angle If the oven is furnished with the
retractable door option, allow a minimum clearance
of 6-1/2 inches (165mm).
q Allow a minimum clearance of 4-inches (102mm)
from the back of the oven for plumbing connections.
qAllow a 20-inch (500mm) clearance at the top of
the oven for free air movement and for the steam
vent(s) located at the top.
qDo not install the oven adjacent to heat producing
equipment such as fryers, broilers, etc. Heat
from such appliances may cause damage to the
controls of the Combitherm. Minimum clearance
recommended: 20-inches (500mm)
Place the Combitherm oven on a stable, non-
combustible level horizontal surface. For countertop
models, the oven stand must be level. Level from front-
to-back and side-to-side by means of the adjustable
legs. In addition, the overall height of the oven should
be positioned so the operating controls and shelves may
be conveniently reached from the front.

VENTILATION REQUIREMENTS
An adequate ventilation system is required for
commercial cooking equipment. Information may be
obtained by writing to the National Fire Protection
Association, Batterymarch Park, Quincy, MA 02269.
When writing refer to NFPA No. 96.
1. A single gas Combitherm oven requires a minimum
of 28 CFM make-up air for natural and propane
gas. Kitchen ventilation must include a provision
for an adequate ow of fresh air for gas combustion
and to prevent a negative-pressure condition. The
bottom of the oven provides air supply access for
gas combustion and must be kept clear at all times.
DO NOT obstruct or restrict ventilation nor the air
ow required to support combustion.
2. DO NOT obstruct the flow of the exhaust flue at
the top rear of the oven. It is especially critical
that gas supply piping and electrical support
cord and/or receptacle be routed away from the
path of the hot combustion fumes.
3. Make certain the oven installation maintains adequate
air ventilation to provide cooling for electrical and gas
components. The area around the oven should be clear
of any obstructions which might retard the ow of
cooling air. Failure to observe this caution may result in

INSTALLATION
GAS SUPPLY & INSTALLATION
Remove any tape
or compound
residue on all
external thread
connections before
proceeding. Use
an approved gas
pipe sealant at all
external threaded
connections,
Gas piping used on gas connections must avoid
sharp bends that may restrict the flow of gas to the
appliance. If the connected pressure exceeds 14.0”
W.C. (3.5 kPa), a step-down regulator is required to
be supplied by the owner/operator.
Close the individual manual shut-off valve to isolate
the appliance from the gas supply piping system
during any pressure testing at test pressures equal
to or less than 1/2 psig. (3,4 kPa). The appliance and
individual shut-off valve must be disconnected from
the gas supply piping system during any pressure
testing at pressures in excess of 1/2” psig. (3,4 kPa).
In the U.S.A., installation must conform to local
codes or, in the absence of local codes, with the
current edition of the National Fuel Gas Code,
NFPA-54 and ANSI Z83.11a CSA 1.8a 2004 (or
latest edition). In Canada, installation must be in

COMBITOUCHTM ESG SERIES • GAS INSTALLATION MANUAL • 18.
INSTALLATION
GAS SUPPLY & INSTALLATION
The minimum size requirement for gas piping or a
flexible connector is 3/4 - inch (19mm). For long runs
of gas piping, the pipe diameter must conform to the
tables in the National Fuel Gas Code, ANSI/NFPA
Z223.1.
A listed gas shut-off valve must be installed
upstream of the appliance to shut off the gas
supply during servicing. The shut-off valve should
be accessible with the appliance in the normal
installation position.
If the oven or the oven stand is supplied with
casters, gas connection must be made with a flexible
connector that complies with the Standard for
Connectors for Movable Gas Appliances, ANSI
Z21.69; or in Canada, Connectors for Movable Gas
Appliances, CAN/CGA-6.16-M87. When using a
flexible connector, a quick disconnect device must
be used to comply with the Standard for Quick-
Disconnect Devices for Gas Fuels, ANSI Z21.41; or in
Canada, Quick Disconnect Devices for Use with Gas
Fuels, CAN1-6.9.
When a quick disconnect device and flexible
connector are used, a restraining device must be
installed to limit the movement of the appliance and
prevent damage to the connector or quick disconnect.
An example of a restraining device would consist
of a 2000 pound test, stainless steel cable, attached
to a structural member of the kitchen wall behind
the oven. The means of attachment should consist
of a quick connect snap so that the oven can be
disconnected when the appliance must be moved
away from the wall.
The other end of the cable should be permanently
attached to the rear frame of the oven. The cable
should be of sufficient length so that no strain is ever
placed on the flexible gas connector in the event of
accidental movement of the oven without properly
disconnecting the gas connector. The flexible
connector should be routed to form a downward
“U” loop between the building gas supply and the
permanent attachment at the rear of the oven.
The routing of the flexible connector must not be
made under the oven. Oven temperatures achieved
during operation are too hot for safe operation. Gas
piping should be installed from the point of gas
connection at the bottom, front of the oven to the
back of the oven where the flexible connector may be
safely used. See the illustration for the recommended
placement.
WARNING
GAS PIPING MUST NEVER
BE INSTALLED TO RUN
UNDER THE BURNER.
