required. The electrical schematic is on the
inside of the service panel and in this manual.
9. Internal gas lines were cleaned and closed off
with a gas valve before the unit was shipped.
Free external gas lines of lint, dirt, metal
chips, sealant, grease, oil, or other contami-
nants before connecting them to the kettle.
10. Connect the kettle gas valve to the gas
service main with ¾ inch IPS line or an
approved equivalent.
11. Installation must conform with local codes
and with the National Fuel Gas Code, ANSI Z
223.1-1988 (or latest edition). Install the unit
in an adequately ventilated room and ensure
an adequate air supply. The best ventilation
will use a vent hood and exhaust fan with no
direct connection between the vent duct and
the flue. Do NOT obstruct the flue or vent
duct after installation.
12. Adequate space for proper service and
operation is required. Do NOT block any air
intake spacings to the combustion chamber
or obstruct the air flow by piling or stacking
anything near the kettle.
13. .After the kettle has been connected to the
gas supply, check each gas line joint for
leaks. DO NOT USE A FLAME TO CHECK
FOR LEAKS. A thick soap solution or other
leak detector should be employed.
14. The appliance and its individual shutoff valve
must be disconnected from the gas supply
piping system during any pressure testing at
test pressures in excess of ½ PSI (3.48
kPa). The unit must be isolated from the gas
supply piping system by closing its manual
shutoff valve during any pressure testing of
the gas piping system at pressures equal to
or less than ½ PSI (3.48 kPa).
15. Check the following points to confirm that
your HH kettle has been installed properly.
a. Sufficient room between the kettle and
nearby objects for cleaning and service.
b. Minimum clearance of six inches from the
kettle’s sides and draft diverter.
c. Unit vented to a hood or chimney.
d. Kettle is level.
e. Correct amount of water in the jacket.
f. Safety valve outlet is pointed down.
g. Connected with a waterproof, 115 volt, 15
amp supply of electric power and
grounded in accordance with electrical
codes.
h. Natural gas lines cleaned before
connection.
i. Gas connected with ¾ inch pipe.
j. Gas line joints checked for leaks.
k. No obstruction to air supply or venting
B. Initial Start-Up.
After installation, the installer should test the
kettle to ensure that it is operating correctly.
1. Remove all literature and packing materials
from the inside and outside of the unit. Clean
out any material that might clog or damage
the tangent draw-off valve.
2. Close the draw-off valve, and put water into
the kettle to a depth of about six inches. Test
draw-off operation by opening it all the way,
then closing it before all the water runs out.
3. Make sure the supplies of gas and electric
power are on.
4. Following “To Start Kettle” instructions on
Page nine of this manual, begin heating the
water at the highest thermostat setting. The
heating indicator light should come on as
soon as you turn up the thermostat dial, and
heating should continue until the water boils.
5. To turn off the unit, follow “To Turn Off Kettle”
instructions on page 10.
If the kettle functions as described, it is ready for
use. If it does not, contact your area Groen
Authorized Service Representative.
