2.4.1 Water Connections
Before connecting water to this unit, have water
supply analyzed to make sure that hardness is no
greater than 2.0 grains per gallon and pH level is within
the range of 7.0 - 8.5. Water which fails to meet these
standards should be treated by the installation of a
water conditioner. EQUIPMENT FAILURE CAUSED
BY INADEQUATE WATER QUALITY IS NOT
COVERED UNDER WARRANTY.
CAUTION: PVC OR CPVC PIPING ARE NOT
ACCEPTABLE MATERIALS FOR USE IN DRAINS.
2.4.2 Electrical Connections
Connect cooker controls to 110/120 volt AC, 60
Hz, single phase branch circuit rated 15 amps capacity.
Wiring will conform to the requirements of national and
local electrical codes, (220 volts, 50Hz, single phase
for export units.
NOTE: ONLY A LICENSED ELECTRICIAN SHOULD
MAKE ELECTRICAL CONNECTIONS.
2.4.3 Gas Connections
Each of the generators are factory adjusted for a
gas input of 40,000 BTU/hr at the pressure indicated.
Please read the rating plate on the top of the unit. If
this plate is marked for a different gas than that
supplied, notify your dealer immediately. Install the
supplied external gas supply shut off valve at the gas
main inlet. This is located just under the bottom edge of
the lower front cover panel. Install so that the shut off
valve handle is clearly visible to the operator.
Use new iron or steel pipe complying with the
latest ANSI Standard for Wrought-Steel and Wrought-
lron Pipe, B36, Properly threaded, reamed and free
from chips, oil, and dirt. If pipe dope is used, apply a
moderate amount leaving two end threads bare. Pipe
dope must be resistant to LP gas. Connect the gas line
into the bottom (inlet) side of the gas

supply shut off valve. The supply pressure must be at
least I" (25mm) water column higher than the manifo ld
or regulator pressure for proper functioning of the
regulator. If it is not, check the supply pipe for blockage
or excessive pressure drop and make the necessary
corrections.
Perform a gas leak test of all newly-made joints,
as well as those leading to the main gas control valve.
Use a soap solution. DO NOT USE FLAME!
Natural gas units are equipped with a pressure
regulator factory adjusted to give 3.5" (89mm) water
column manifold pressure.
Propane gas units are equipped with a pressure
regulator factory adjusted to give 11" (279.5mm) water
column manifold pressure.
For conversion to either natural or propane
gas, 3 components must be changed. They are:
1. Gas orifices for each of the main burners.
2. Both complete pilot burners.
3. Springs inside each o f the gas regulator
valves.
Consult the Market Forge for more detailed
information, instructions, and part numbers for
field conversion to either natural or propane gas.
NOTE: ONLY A LICENSED GAS FITTER SHOULD
MAKE GAS LINE CONNECTIONS.
2.4.4 Initial Systems Inspection
After the cooker is set in place, and all service
connections have been made, the cooker must be
given a final systems inspection prior to use. This is to
determine that all systems are functioning properly.
This procedure is described in fu ll detail in Section 3,
"Initial Systems Inspection", of this manual. If all
systems perform as described in Section 3, the cooker
is ready for cooking use. If any of the systems are not
functioning as they should, consult Section 5,
"Troubleshooting" in this manual.
