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.
