INSTALLATION

SETTING UP THE URN — Place the urn carefully in position on urn stand or counter. Faucets should be located over a drip trough or similar

receptacle. Then connect water supply, electric, gas or steam in accordance with the following suggestions:

WARNING: GAS URN — Do not install gas urn near a combustible wall or counter top without proper insulation.
WATER CONNECTIONS — Connect urn water inlet connection with matching size water supply pipe. Valve inlet is 1/2" i.p.s. pipe. Somewhere in

the water supply line before the urn, there should be a union and shut-off valve for easy connection or later change. If local plumbing code requires
a check valve and vacuum breaker before urn inlet, be sure plumber has this part installed. A reducing valve should be provided if water pressure
is over 45 P.S.I.

ELECTRIC CONNECTIONS — Be sure that your current characteristics (voltage, etc.) agree with data specified on metal plate attached to urn.
An experienced electrician should make the installation and he should check that the proper size power cable leads to your urn and that the
circuit is fused adequately. (Do not supply power to a dry urn.)

GAS CONNECTIONS — Connect 1/2" gas supply. Burner is rated at 22,000 BTU on twin LSQ urn and 15,000 BTU on single LSQ urn. (Do not
apply heat to a dry urn).

STEAM CONNECTIONS — On steam heated urns, it is also recommended that a valve be placed in the steam line before the steam line is
connected to the urn. Steam pressure at urn location (not at your steam boiler) should match the pressure for which the urn was built, as indicated
on tag attached to the urn. Excessive pressure can be reduced by installing a reducing valve. Too low a pressure may result in insufficient heating
and improper functioning of the thermostat. Steam lines must be blown out before installation to eliminate any accumulation of chips, dirt or white
lead that may clog system.

ADJUSTMENT OF THERMOSTATS — Normally the thermostats should not have to be adjusted after installation. However, if any adjustment is
required, see pages 5-7.

should be approximately 20-25 Ibs. Do
not use a different pressure unless your
urn was ordered for it

b. Never allow water level in boiler gauge

to go lower than 3 inches from bottom

HOW TO ADJUST THERMOSTAT

(For electrically heated urns)

THERMOSTAT CALIBRATION

Your thermostat should be calibrated if it cycles off
before the urn reaches the brewing range on the dial
thermometer (200° - 205°F) or if the urn reaches a
boiling point.

To Calibrate Thermostat:

1. Turn control to off position and remove black knob.

2. With a small screwdriver, turn screw "A" clockwise
to decrease and counter-clockwise to increase the
temperature.

3. Adjusting the calibration screw 1/4 turn will increase
or decrease the temperature approximately 10°F.

4. Replace knob and turn thermostat back to the No.
10 position and check to see if it is calibrated
properly. When the thermostat is in the No. 10
position — dial thermometer should stay in the
brewing range.
