INSTALLATION
Kettle Installation & Utility Connection
KETTLE INSTALLATION
1. Uncrate carefully. Report any hidden freight damage
to the freight company immediately.
2. The pressure relief valve is located at the right rear of
the unit. This area should be kept clear and should
not be in an area where operators will normally stand.
The elbow on the relief valve should be turned toward
the floor. A maximum 3 foot, 3/4” diameter pipe may
be used to extend to the floor, but must not be piped
directly to a drain. It must vent to the atmosphere.
3. Set the unit in place. Be certain to maintain minimum
clearances as stated above.
4. To level the unit use a spirit level in all directions on
the top of the kettle (lid up). Adjust the bottom foot on
each leg to overcome an uneven floor.
5. Mark hole locations on floor through anchoring holes
provided in flanged adjustable feet.
6. Remove appliance and drill holes in locations marked
on floor and insert proper anchoring devices.
7. Set unit back in position and re-level left to right and
front to back.
8. Bolt and anchor appliances securely to the floor.
9. Seal bolts and flanged feet with silastic or equivalent
compound.
10. Appliance location must allow air supply to unit and
obstruction free clearance for air opening into the
combustion chamber.
11. Make service connections as indicated.
12. Check the pressure gauge on the front panel before
operating. If the pressure gauge does not indicate
green vacuum zone (below 0 psi), see “Re-establish-
ing Vacuum” section under SERVICE, after complet-
ing installation instructions.
GAS CONNECTION
The serial plate on the lower right side of the unit indicates
the type of gas your unit is equipped to burn. Do NOT
connect to any other gas type.
A 3/4” NPT line is provided at the rear for the connection.
Each unit is equipped with an internal pressure regulator
which is set for 3.5” W.C. manifold pressure for natural
gas and 4.0” W.C. for propane gas. Use 1/8” pipe tap on
the downstream side of the combination valve for check-
ing pressure.
An adequate gas supply is imperative. Undersized or low
pressure lines will restrict the volume of gas required for
satisfactory performance. A steady pressure, minimum 6”
W.C. for natural gas and minimum 11” W.C. for propane
gas, is recommended. With all units operating simultane-
ously, the manifold pressure on all units should not show
any appreciable drop. Fluctuations of more than 25%
on natural gas, and 10% on propane gas, will create pi-
lot problems and affect burner operating characteristics.
Contact your gas company for correct supply line sizes.
Purge the supply line to clean out any dust, dirt, or other
foreign matter before connecting the line to the unit. It is
recommended that an individual manual shut off valve be
installed in the gas supply line to the unit. Use pipe joint
compound which is suitable for use with LP gas on all
threaded connections. Test pipe connections thoroughly
for gas leaks.
WARNING
All connections must be checked for leaks,
after the unit has been put in operation. Use
soapy water only for testing on all gases.
Never use an open flame to check for gas
leaks.
NOTICE
If applicable, the vent line from the gas appli-
ance pressure regulator shall be installed to
the outdoors in accordance with local codes
or, in the absence of local codes, with the Na-
tional Fuel Gas Code, ANSI Z223.1/NFPA 54, or
the Natural Gas and Propane Installation Code
CSA B149.1, as applicable.
NOTICE
If this equipment is being installed at over
2,000 feet altitude and was not so specified on
order, contact service department. Failure to
install with proper orifice sizing may void the
warranty.
