damage or shipment errors to the delivery agent.
Write down the model number, serial number, and
installation date for your unit at the top of the
Maintenance and Service Log at the back of this
manual. Keep the manual with the unit.
To remove the kettle from the box, cut any straps from
around the box. Detach the box sides from the skid.
Pull the box up off the unit, taking care to avoid damage
or injury from any staples left in the box walls. When
installation is to begin, cut the straps holding the kettle
to the skid, and lift the kettle straight up off the skid.
Examine the packing materials to make sure no loose
parts are discarded with the materials.

WARNING
THIS PRODUCT MUST BE INSTALLED BY A LICENSED PLUMBER OR GAS FITTER WHEN
INSTALLED WITHIN THE COMMON WEALTH OF MASSACHUSETTS. IMPROPER INSTALLATION CAN
CAUSE INJURY TO PERSONNEL AND/OR DAMAGE TO THE EQUIPMENT.
THIS UNIT IS FOR COMMERCIAL USE. NEVER USE HOME OR RESIDENTIAL GRADE GAS CONNECTIONS.
THEY DO NOT MEET GAS CODES AND COULD BE HAZARDOUS.
Installation and Initial Start-Up
A. Installation
The unit should be installed in a ventilated room for
efficient performance. items which may obstruct or
restrict the flow of air for combustion and ventilation
must be removed. The area directly around the
appliance must be cleared of all combustible materials.
1. Installation requires connection with gas and
electrical services. See items 8 to 14 for details.
2. To protect the unit from damage, leave it on the
shipping pallet until the time of installation. When
installation is to begin, cut the straps holding the
kettle, and hoist the kettle straight up off the skid.
NOTICE
To avoid damaging parts of the burner system
underneath the kettle, LIFT THE UNIT ONLY BY THE
RING beneath the outer portion of the body.
3. Install the unit with a minimum clearance to
combustible and non-combustible construction of six
inches at the sides and six inches between the draft
diverter and the wall. Also leave enough room for
cleaning, maintenance, and service.
4. The draft diverter shipped with the kettle is the
correct height and shape to give maximum
performance. Install the draft diverter as shown on
Figures 1 and 2 above. Securely fasten the screw
to attach draft directly. Do not change the diverter
in any way.
WARNING
DO NOT ATTACH THE UNIT TO A TYPE “B” VENT.
FAILURE COULD RESULT IN FIRE OR PROPERTY
DAMAGE.
Install the unit under a ventilation hood, or vent the
flue directly to a masonry chimney. Put a hood at
least several inches above the upper end of the draft
diverter. Do not rest hood supports on the diverter.
Installation of a ventilating hood should comply with
local codes and/or ANSI/NFPA-96 Latest Edition.
Also, local codes may require that the kettle be
electrically interlocked to shut off the gas supply
and prevent the operation of the unit if the
exhaust fan is not operating or if the fire
suppression system is activated. Failure to
follow these instructions can cause bodily injury
and/or property damage.
5. To level the unit, adjust leg length by turning the
bullet feet
6. Make sure the water level is correct in the
jacket, by confirming that the level is between
the marks on the gauge glass. If the water level
is low, follow the instructions under “Jacket
Filling” in the “Maintenance” Section of this
manual.

Operation
WARNING
ANY POTENTIAL USER OF THE EQUIPMENT MUST BE TRAINED IN SAFE AND CORRECT OPERATING
PROCEDURES
A. Controls
Operator controls for the AH/1 kettle are:
1. Manual gas valve which controls the supply of gas
from the main line to the unit.
2. On-Off (toggle) switch. This switch turns the control
circuit power supply on or off.
3. Thermostat dial, which turns the thermostat on or off,
and sets the kettle operating temperature.
4. Indicator Lights to alert operator of unit conditions:
a. Power On Indicator - shows that the unit is turned
on
b. Heat Indicator - indicates that main gas is on to
produce steam in the kettle jacket.
c. Low Water indicator - shows that jacket water is
low
d. Unit gas pressure regulator adjustment - located
behind the access door in the kettle skirt.
B. Operating Instructions
WARNING
KEEP AREA AROUND KETTLE FREE AND CLEAR OF
ALL COMBUSTIBLE MATERIALS.
DO NOT ATTEMPT TO LIGHT ANY BURNER WITH A
FLAME.
CAUTION
HEATING AN EMPTY KETTLE MAY CAUSE THE
RELEASE OF STEAM FROM THE SAFETY VALVE.
1. To Start Kettle
a. CHECK THE WATER LEVEL IN THE JACKET
EVERY DAY. The level should be at the middle
of the sight glass. If the level is low, see Jacket
Filling in the Maintenance section of this manual
b. Check the pressure/vacuum gauge. If the gauge
does not show 20 to 30 inches of vacuum (i.e. a
reading of 20 to 30 below zero), see Jacket
Vacuum in the Maintenance section of this
manual.
c. DO NOT attempt to light any burner with a
flame.
d. Open main supply gas valve (handle in line
with the pipe).
e. Turn the toggle switch to ON. For 90
seconds, or until it succeeds, the electronic
ignition control will attempt to light the pilot.
f. Once the pilot is lit, turn the thermostat to
the desired setting.
g. If the pilot does not light, turn it off and wait
five minutes. At that time follow the
instructions for starting once again.
h. If the unit repeatedly fails to light, contact
an authorized Groen Service Agency for
assistance.

SYMPTOM WHO WHAT TO CHECK
indicates items which must be performed by an authorized technician.
Safety Valve pops open User a. For air in the jacket. See “Jacket Vacuum” in the Maintenance section.
b. Thermostat dial setting.
Auth
Service
Rep Only
c. For defective thermostat. The thermostat should click when the dial is
rotated to settings above and below the temperature of the kettle. If
defective, replace.
d. For defective safety valve. If the valve pops at pressures below 29 PSI,
replace.
Burners will not light. User a. That the main gas supply valve is open. (handle is in line with the gas
pipe).
b. Gas supply to the building.
Auth

d. Thermostat operation. The thermostat should click when the dial is
rotated to settings above and below the temperature of the kettle.
System does not produce a spark Auth
Service
Rep Only
a. AC voltage between terminals on secondary side of transformer with
unit power turned on. If it is not 24 Volt, replace the transformer
b. That the high tension cable is firmly attached and in good condition. If
cracked or brittle, replace.
c. Pilot burner ceramic insulatorfor crack or break.
d. Pilot spark gap. Regap.
Spark is present but the pilot will
not light.
Auth
Service
Rep Only
a. That the pilot valve is securely connected to terminals.
b. For 24 VAC at terminals PV and PV/MV. If 24V is not present, replace
the ignition control module.
b. That gas pressure is at least 3.5" W.C.(8.7818
b).
c. For gas at the pilot. If it is not flowing:
(1) Check the pilot gas line for kinks and obstructions.
(2) Clean orifice, if necessary.
(3) Check magnetic operator for pilot valve on gas valve. Repair or
replace as necessary.
d. That the pilot spark gap is located in the pilot gas stream. If not, adjust
or replace the pilot burner.
e. For drafts. Shield the pilot burner, if necessary.
Pilot lights, but main burner will
not come on and spark does not
stay on.
Auth
Service
Rep Only
a. For 24 V between terminals MV and PV/MV while pilot is burning. If
24V is not present, replace the ignition control module.
b. That gas pressure is at least 3.5" W.C.(8.7818
b).
c. Electrical connections of the main valve to terminals, to assure that they
are securely attached. Check magnetic operator for main valve on gas
valve. Repair or replace as necessary.
Pilot lights, but main burner will
not come on, the spark stays on.
Auth
Service
Rep Only
a. Check for bad burner ground. If necessary, repair with high
temperature wire.
b. Pilot burner ceramic insulator for cracks.
c. That cable is not grounded out. If it is, correct the ground-out condition
or replace cable.
d. For proper gas pressure.
e. Clean pilot assembly, or replace if necessary.
f. Tighten all mechanical and electrical connections.
g. If the pilot flame is weak, increase pilot orifice size.
h. Replace ignition control module.
Main burner comes on but will not
stay on.
Auth
Service
Rep Only
a. Check burner ground for bad wire or connection. Replace if necessary
with high temperature wire.
b. Check for low gas supply pressure. If necessary, replace ignition
control module.
