COMMISSIONING
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 regulators 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 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 and Adjustments.
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.
Testing
1. Be sure that all valves and thermostats are in the “OFF”
position.
2. Turn on the main gas supply valve. Light all top section
pilots.
3. Leak test all valves and fittings as described in the
procedure above. Correct any leaks as required and
recheck.
4. Light oven pilot.
5. If the range is provide with an oven shut-off valve
separate from the thermostat, turn this valve on and set
the thermostat at 500°F (260°C) degrees. If the range
oven thermostat has an “OFF” position on the dial the
thermostat is equipped with an internal, integral shut-off
valve. Set this thermostat dial to 500°F (260°C) degrees. 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 rang 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.
CAUTION
: Gas will flow to top burners even with top pilots
out. Gas will not be interrupted. It is the responsibility of
the operator to check the ignition of the burners. Should
ignition fail after ten (1) seconds, turn burner valve off and
wait five (5) minutes and then try again.
Pressure Settings (All Models)
1. Make sure all gas valves are in the OFF position and turn
on the main gas supply.
2. Light all pilots in accordance with the User’s Instructions.
3. Connect a U-gauge manometer to the pressure test point
on the main manifold and turn all gas controls to the ON
position.
Confirm that the pressure is the same as stated on the rating
plate.
Burner Adjustments
Air Shutters
Open Top Section
1. Check that the air shutter is set to the required opening.
(Refer to figure 6)
2. Adjust setting as necessary.
