Installation
Refer to the following pages for important information regarding the
installation of LCS and LCG ClimaPlus Combis. It is recommended
that installation be accomplished by a certified and properly trained
technician.
NOTE: When installing a ClimaPlus combi, humidity calibration must
be performed. This process takes approximately 45-60 minutes. (page 62)

NOTE: With total reset procedure all custom programs are deleted. After a total
reset, 12:00 or 13:00 will be indicated on the timer display. Real time must be
reset. To set clock to actual time, see page 50.

Sensor key, and IQT key simultaneously until the word “VERSION”
appears next to the IQT key.
I Use Central Dial to select CALIBRATE.
I Close cabinet door.
I To start calibration press PROG/START and TEMPERATURE key
simultaneously.
I Calibration starts automatically and lasts 45-60 minutes.
I After calibration, unit must be switched off for 5 seconds before using again.
I During calibration, several values will be shown on the display.
I Once calibration begins, do not interrupt the process.
I Do not open door until calibration is complete.
After calibration, very hot steam–around 392°F (200°C)–remains in the cabinet.
When opening the cabinet door hot steam will escape, and burns could result.

I For drain connection (Fig. 12) use only steam temperature resistant pipe,
diameter 2 in. (50 mm) and constant slope 5%. No hose should be used.
I Direct drain connection is possible, ventilated gap is an integrated part of the
WA
appliance (Fig. 13).
I Drain pipe should be supported to the wall/floor.

I To connect a dual water supply–treated soft water or warm water below
I 140°F (60°C)–disconnect T-water connection at the two water inlets (Fig. 15).
Connect treated water to water inlet marked WZ2 and standard water to inlet
marked WZ1. Treated water must comply with the above-mentioned water
specifications.
NOTE: If using external filter to treat hard water: Contact your Henny Penny
distributor for average water consumption when using CleanJet. Increases in
average water consumption may exceed specifications of external filters and may
affect the frequency of filter maintenance. (See page 57)

Ventilation
Contact your local regulatory agency for ventilation requirements. If a ventilation
hood is installed, observe the following:
I The standards of the local authority.
I The hood should protrude 12-20 in. (300-500 mm) over the front of the
appliance.
I The integrated grease filter should be in the protruding part of the hood.

INSTALLATION
continued
DO NOT attempt to use any type of gas other than that specified on the data
plate. Incorrect gas supply could result in fire or explosion resulting in severe
injuries and/or property damage.
To avoid possible serious personal injury, the installation must conform with local
codes, or in the absence of local codes, with the National Fuel Gas Code, ANSI
Z223.1-1988 or latest edition. In Canada, CAN/CGA-B 149.1 Natural Gas
Installation Code CAN/CGA-B 149.2 Propane Installation Code.
I All Henny Penny Combi-Steamers are equipped with two heat exchanger
systems. One is responsible for steam production, the second for dry heat. Each
individual heat exchanger is heated with a separate burner assembly.
I Separate gas valves for the steam burner and dry heat burner are responsible for
the gas supply to the individual burners. All LCG models have manual shut-off
valves that can be accessed from the left without tools. To operate the valves,
unscrew the two knurled screws and remove the service cover. Open or close
manual valves as desired.
Gas Leak Test
I After piping and fittings have been installed, check for gas leaks. A simple
checking method is to turn on the gas and brush all connections with a soap
solution. The appearance of bubbles indicates escaping gas. In this event, the
piping connection must be redone until no bubbles occur.
Never use a lighted match or open flame to test for gas leaks. Escaping gas could
result in fire or explosion resulting in severe injuries and/or property damage.
Gas pressure
I The gas pressure should be measured when all other gas appliances in the
kitchen are on high flame. The minimum and maximum incoming line flow
pressures should be as follows:
Natural: 7-10 in. water column (18-25 mb)
Propane: 12-14 in. water column (30-35 mb)
65
INSTALLATION
During pressure testing note the following:
continued
1. The unit and its individual shut-off valves must be disconnected from the gas
supply piping system during any pressure testing of that system when test
pressures exceed 1⁄
gas supply line.
2
psig (3.45kPa). Turn OFF main gas shut-off valve or main
2. The unit must be isolated from the gas supply piping system by closing its
individual manual shut-off valves during any pressure testing of the gas supply
piping system at test pressure equal to or less than 1⁄
psig (3.45kPa).
2
3. If incoming pressure is over 14 in. water column (35 mb) a separate regulator
must be installed ahead of the manual gas shut-off valve.
To prevent damage to the control valve regulator, the first time the gas valve knob is
turned to the ON position, it is very important to turn the knob very slowly.
NOTE
After turning on the gas, the manual shut-off valve must remain open, except
during pressure testing as outlined above, or when necessary during service
maintenance.
I Incoming pressure reading can be taken by installing a gas pressure gauge on
the front of the unit’s main gas valves test port. This should be done with all
gas appliances in operation on the same gas supply line. Should the manifold
pressure drop below the desired level, consult your local gas utility service.
Gas Hook-up
RIGHT
WRONG
A minimum pull of appliance
away from wall is acceptable in
order to disconnect hook-up.
Maximum pull prior to disconnect
will result in kinked ends and reduce
hose and connector life.
66
INSTALLATION
Utilize elbows when necessary to avoid sharp kinks or excessive bending. For ease of
movement, install with a “lazy” loop. Gas appliance must be disconnected prior to
maximum movement. (Minimum movement is permissible to disconnect gas line.
continued
Couplings and hose should be installed in the
same plane as shown at left. DO NOT OFFSET
COUPLINGS. This results in twisting and undue
torsion causing premature failure.
Correct way to install metal hose for vertical traverse.
Note single, natural loop. Allowing a sharp bend,
shown at right, strains and twists the metal hose to
a point of early failure at the coupling.
Maintain the minimum or larger bending diameter
between couplings for the longest life. Couplings too
close together, as shown at right, create double bends
causing work fatigue failure of fittings.
In all installations where self-draining is not necessary,
connect metal hose in a vertical loop. DO NOT
CONNECT METAL HOSE HORIZONTALLY
unless self-draining is necessary. Then use support on
lower plane as show at left.
Cable Restraint
Please refer to the illustration at left when installing cable restraint on all moveable
gas appliances
Eye-bolt is to be secured to the building using acceptable building practices.
Dry wall construction
Secure eye-bolt to a framing stud. DO NOT attach to dry wall only. Locate eye-bolt
at the same height as the gas service approximately 6 in. (150 mm) to either side of
service. Cable restraint must be at least 6 in. (150 mm) shorter than flexible gas line.
