3.1 Gas Model Installation
Although groen recommends the Tri-Res is installed near non-
combustible surfaces, the following minimum clearances are to
any surface, combustible or non-combustible.
Right Side..............................6 inches
Left Side ...............................6 inches
Rear.......................................0 inches from motor
Recommended Service Clearances
Right Side..............................14 inches
Left Side ...............................6 inches
Rear.....................................24 inches
Front.....................................36 inches
The Tri-Res must be installed in a well-ventilated room with an
adequate air supply. The Tri-Res must be installed beneath a
ventilation hood since gas combustion products exit the appliance.
Any item which might obstruct or restrict the flow of air for
combustion and ventilation must be removed. Do not obstruct
the flue cover or rear vents after installation.
The area directly around the appliance must be cleared of all
combustible material. The installation must conform with lo-
cal codes or, in the absence of local codes, with the National
Fuel gas Code, ANSI Z223.1/NFPA 54, or the Natural gas and
Propane Installation Code, CSA B149.1
The unit and it individual shutoff valve must be disconnected
from the gas supply which has test pressures in excess of 1/2
PSI (3.45 kPA). It must be isolated from the gas supply piping
system by closing its individual manual shutoff valve during any
pressure testing of the gas supply piping system which has test
pressures equal to or less than 1/2 PSI (3.45 kPA).
1. Electrical Supply Connection
Provide 115 VAC, 60 HZ, 1 PH, 15 AMP service. Bring wire in
through hole on the back panel. Each cavity requires a separate
cord for connection. Local codes and/or the National Electrical
Code should be observed in accordance with ANSI/NFPA 70.
AN ELECTRICAL gROUND IS REQUIRED. The wiring diagram
located in the service compartment and in this manual. Maxi-
mum load is 12 AMPs. In Canada, provide electrical service in
accordance with the Canadian Electrical Code, CSA C22.2 Part
1 and/or local codes.
2. Gas Supply Connection
Connection to the gas supply shall be in accordance with the
chart below. Supply pressure must be at least 5” W.C. (maxi -
mum 14” W.C.) for natural gas or 12” W.C. (maximum 14”
W.C.) for LP gas. In Canada, the installation must conform to
the Canadian gas Code, CAN 1-B149, Installation Codes for
gas Burning Appliances and Equipment and/or local codes.
Check all gas connections for leaks prior to unit operation.
Ratings for Gas Tri-Res
*Measured at gas manifold
After the unit has been connected to the gas supply, all gas joints
must be checked for leaks. Do not use flame checking for leaks. A
thick soap solution or other suitable leak detector should be used.
WARNING
The unit must be installed by personnel who are
qualified to work with gas, electricity and plumbing.
Improper installation can cause injury to personnel and/
or damage to the equipment. The unit must be installed
in accordance with applicable codes.
CAUTION
Do not install the unit with the rear vents blocked or
within 6 inches of a heat source such as a braising pan,
deep fat fryer, charbroiler or kettle.
To avoid drainage problems, level the unit front to back
and pitch it slightly to the rear.

After the unit has been connected to the gas supply,
all gas joints must be checked for leaks.
Do NOT use
open flame to check for leaks. A thick soap solution
or an electronic leak detector should be used.
F or a U nit on casters:
A. The installation shall be made with a
connector that complies with the standard
for connectors for movable gas appliances;
ANSI Z 21.69.CSA 6.16, and a quick-
disconnect device that complies with the
standard for quick-disconnect devices for
use with gas fuel, ANSI Z21.41.CSA 6.9.
B. Adequate means must be provided to limit
the movement of the appliance without
depending on the connector and the quick-
disconnect device or its associated piping to
limit the appliance movement.
C. The location where the restraining device
may be attached to the appliance shall be in
acordance with Groen specifications for the
device.
4. Water C onnection(s)
Install a check valve to prevent back flow
in the incoming cold water line, as required
by local plumbing codes. Water pressure
in the line should be between 30 and 60 PSI. If
pressure is above 60 PSI, a pressure regulator
will be needed. These pressures must
provide the
1.5 gallons per minute required for
proper unit function.
A
3
/
4
inch female NH connector (garden hose
type) is used to attach the water supply to the
inlet valve. M inimum inside diameter of the
water feed line is 1 /
2
inch. Use a washer in the
hose connection. Do not allow the connection to
leak, no matter how slowly. Do not over-tighten
hose connections.
This equipment is to be installed to comply
with the basic plumbing code of the Building Officials
and Code Administrators International, Inc.
(BOCA) and the Food Service Sanitation Manual
of the Food and Drug Administration (FDA).
NOTE: Local code may also require check
valves in the water supply line.
5. Drain C onnection
Level the unit and pitch it slightly to the rear
(maximum
1 /
4
inch) by adjusting the optional
legs or the bullet feet on the optional stand.
A drain hose of 1
1
/
2
” inside diameter is required.
W ARNING:
DO NOT CONNECT THE DRAIN DIRECTLY TO
A BUILDING D RAIN. BLOC KING THE DRAIN IS
HAZARD OUS.
There must be a free air gap between the end of the
hose and the building drain. The free air gap should
be as close as possible to the unit drain. There must
also be no other elbows or restrictions between the
unit drain and the free air gap.
CAUTION
D O NOT USE PLASTIC PIPE. DRAIN MUST BE
RATED FOR BOIILING W ATER.
Install the drain line with a constant downward pitch.
IMPORTANT: D o not allow water traps in the line.
A trap can cause pressure in the cavity, which
may cause the door gasket to leak.
P roper Drain Line C onnection –– Drain Line
must have a constant downward pitch of at least
1 /
4
” per foot. O bserve local code regarding air
gap spacing and drain connections.
In Canada, the installation must conform to the
Canadian Gas Code, CAN 1-B1 49, Installation
Codes for Gas Burning Appliances and Equipment
and/or local codes.
