INSTALLATION Continued

Pressure Regulators

1.Must have a maximum regulation capacity for the total connected load.

2.The pressure regulator(s) installed must be listed by a nationally recognized agency.

3.The pressure regulator(s) must have a pressure adjustment range to allow adjustment to the manifold pressure on the appliance rating plate.

4.Unless the manifold pressure on all connected appliances is the same, a separate pressure regulator must be supplied for each appliance(s) having differing manifold pressures.

5.Gas supply lines may be connected at right, left or both ends of a battery or at the tee connections on spreader plates. If five (5) or more units are placed in a battery, more than one (1) supply line should be used. A readily accessible, approved type of hand shut-off valve should be installed on each supply line.

WARNING:  Local codes may require that the pressure regulator be externally vented. This will be supplied by others.

Testing

All fittings and pipe connections must be tested for leaks. Use approved gas leak detectors, soap solutions or equivalent, checking over and around the fittings and pipe connections. DO NOT USE A FLAME! Accessibility to all gas

lines and fittings require that valve panel(s) lower front panel(s), oven rack(s) be removed. It may be necessary to remove or at least raise and securely prop griddles, hot tops and top grates. All parts removed (including fasteners) should be stored safely for re-use.

1.Be sure that all valves and thermostats are in the ‘off’ position.

2.Turn on the main gas supply valve.

3.Leak test all valves and fittings as described in the procedure above. Correct any leaks required and recheck.

4.Light oven pilot.

5.The range is provided with an oven shut-off valve separate from the thermostat, turn this valve on and set the thermostat at 500°. If the range oven thermostat has an “off” position on the dial the thermostat is equipped with an internal, integral oven shut-off valve. Set this thermostat to 500°. In both cases, gas will now flow to the oven burner.

6.Leak test all valves, fittings, etc. as above. Correct any leaks and retest.

7.Shut off all range valves and set thermostat dials to ‘off’ or low position.

All units are tested and adjusted at the factory. However, burners and pilots should be checked at installation and adjusted if necessary.
