Section A
GENERAL INSTRUCTIONS
1. Preliminary operations
Make sure the appliance is supplied complete and has not been damaged in transit.
2. Positioning
Keep the appliance area free and clear of combustible material and do not obstruct the flow of combustion or ventilation air.
The installation of any components such as a vent hood, grease extractors, and/or fire extinguisher systems, must conform to the their applicable nationally recognized installation standards.
For the exact position and size of connections, consult the gas connection chart enclosed in Section B.
All gas connections must be in accordance with local codes and comply with the National Fuel Gas Code ANSI Z223.1 latest edition, Natural Gas Installation Code CAN/CGA - B149.1 or Propane Installation Code CAN/CGA - B149.2.
Connect each oven separately. A gas shut off valve must be installed to the oven(s) and located in an accessible area.
This 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 PSGI (3.45 kPA) and 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 system at test pressures equal to or less than 1/2 PSIG (3.45 kPA).

This appliance is to be installed to comply with the applicable Federal, state, or local plumbing codes having jurisdiction.
Always install a stop-valve upstream of the appliance.
Downstream of the stop-cock, install appropriate fittings for easy disconnection of the appliance and filters which can easily be inspected and cleaned.
Use materials, seals and fittings approved according to applicable standards. Use suitable pipes which have properly treated in order to prevent the release of iron oxides into the water (as these can alter the taste of the food and mark stainless
steel)Make.sure the water specifications are within the limits indicated in section B.
If necessary, install a suitable water treatment system.
