INSTALLATION:
Mount the flare stack vertically by bolting to a standard ANSI 150# pipe flange with a suitable gasket, or mount the
anchor plate with studs in a foundation. Tighten bolts alternately and uniformly. If anchor plate is used, the stack
should be leveled and grouted in place. [See Bolt Torque Table 4 pg. 8]
Mount control panel on wall or suitable support structure at the specified minimum distance from the waste gas
burner; see drawing C-87532, Page 10 or C-87533, Page 11. The pilot gas line should be a minimum 1/2" ID pipe or
tubing.
Connect control panel to ignition transformer box as shown on drawing A-87463, Page 13. The transformer box is
grounded to the flare stack. The pilot gas line should be hydrostatically tested according to local codes. At a
minimum, the test pressure should be maintained for at least 30 minutes at 1.5 times unregulated supply gas
pressure.
The complete piping system must be bubble tight. Inspect the inspirating venturi and gas line to ensure that is free
of contaminants such as dirt, insects, nests, etc. prior to installation.
Connect 115/60/1 VAC [or other optional power supply as specified on purchase order] to the control panel following
both the National Electric Code and local code guidelines.
Do not attempt to light the pilot until performing the system check-out.
WARNING:
The solenoid valve can freeze in either the open or closed position if exposed to temperatures below 32 o F.
The valve must either be installed in a protected environment or heat traced and insulated.
SYSTEM CHECK-OUT:
Before a waste gas burner is placed into operation, the complete system must be checked carefully. The check list
below may include items that are not included in your system.
Note:
Some of these checks have been performed at the factory. However, since a long time period may have
occurred between shipment of the equipment and start-up, it is recommended to check all applicable items.
1. Pressure test the pilot gas line.
2. Pressure switch function - isolate switch and raise pressure checking that NO terminal contacts are closed. If
control panel is equipped with automatic mode option, check that PILOT GAS ON lamp is illuminated when
pressure switch is energized.
3. Solenoid valve function. Supply power and confirm that valve opens; disconnect power to check shut-off.
4. Back-Pressure Regulator [if applicable]. Isolate regulator from system and confirm that regulator opens at
desired set pressure.
5. Check Valve - ensure that it is installed in correct flow direction.
6. Connect power supply to control panel. With pilot gas supply closed, check ignition cycle by switching the
Control Panel to manual or providing signal from the remote switch. Observe both spark and duration of "spark
on" - "spark off" cycles. Refer to operation instructions on page 4.
7. The air injector has been adjusted to the specified gas supply pressure. However, it may be necessary to adjust
the air intake plate to optimize the pilot flame. Do NOT remove the Flame Check, drawing C-84652, page 16,
which is installed in the gas supply port of the injector.
