the kettle.
10. Connect the gas cock of the kettle to the gas service
main with 3/4 inch IPS line or approved equivalent
11. Installation must conform with local codes, or in the
absence of local codes, with the National Fuel Gas
Code, ANSI Z 223.1-1988 (or latest edition). The
unit should be installed in an adequately ventilated
room with a provision for adequate air supply. The
best ventilation will utilize 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.
In Canada
, the installation must conform to the
CAN/CGA B149 Installation Codes for Gas Burning
Appliances and Equipment and/or local codes.
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, all gas line joints must be checked for leaks.
DO NOT USE A FLAME TO CHECK FOR LEAKS
.
A thick soap solution or other suitable leak detector
should be employed.
14. For a unit on casters, complete connection to the
gas supply with connectors that comply with the
standard for connectors for moveable gas
appliances, ANSI Z21.69 — latest edition. Restrain
movement of the unit by attaching a cable or chain
to the eyelet (provided at the back of the frame) and
anchoring the cable or chain to the wall or floor.
Make the length and location of the cable such that
the unit cannot pull on the gas connection while the
cable is connected.
15. The appliance and its individual shutoff valve must
be
disconnected
from the gas supply piping system
during any pressure testing of that system at test
pressures
in excess of
1/2 PSIG (3.48 kPa). The
appliance 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 at test pressures
equal to or less
than
1/2 PSIG (3.48 kPa)
16. Check the following points to confirm that your AH
kettle has been installed properly.
electrical, or gas type change must be approved

to a vent.
d. Kettle level.
e. Correct amount of water in the jacket.
f.

g. Connected with a waterproof, 115 volt, 15
amp supply of electric power in accordance
with electrical codes.
h. Gas lines cleaned before connection.
i.
Gas connected with 3/4 inch pipe or
equivalent
j.
Gas line joints checked for leaks.
k. No obstruction to air supply or venting.
B. Initial Start-Up
After the kettle has been installed, the installer
should test to ensure that it is operating correctly.
1. Remove literature and packing materials from
inside and outside of the unit.
2. Install the TDO valve.
3. Put a small amount of water into the kettle.
4. Verify that kettle water level is normal and that
kettle is holding vacuum in jacket. Correct if not.
5. Make sure the supplies of gas and electric
power are on.
6. Follow the

Heating” in “Operating Instructions,” below.
If the kettle functions as described, it is ready for
use. If the unit does not operate as designed,
contact authorized Groen Service Agent.
8. Provide 115 VAC, 60 HZ, 1 PH, 15 AMP
electrical service for standard unit. Unit may be
equipped for alyternate electrical service of 208
VAC or 240 VAC, as ordered. Use 1/2 inch
waterproof conduit and waterproof connections.
Observe local codes and/or The National
Electrical Code in accordance with ANSI/NFPA
70 - latest edition.
AN ELECTRICAL GROUND
IS REQUIRED
