EMECS Test Fire Checklist
This procedure guides technicians through a full test fire of an EMECS unit, starting with pre-start checks of the panel seal, fire extinguishers, trailer paperwork, grounding and the generator. It then covers starting the blowers, vaporizer and EMECS unit, running integrity, torque, operational and interlock checks, shutting down safely, and completing a final walkaround with inspector and supervisor sign-off.
Inspector/s Name:
Supervisors Name:
EMECS Unit#
Date of Test Fire:
Is the car seal installed and intact on the main panel, with no signs of tampering or unauthorized entry?
if the answer is "noneOf [PASS]"
Check that the SO cord is connected and snug inside of the panel before energizing power to the unit.
Check for any loose wires or disconnected wires. Reinstall and tighten to spec.
Verify that the two fire extinguishers on the unit are ready to use, not damaged, the seal is intact, the UL tag in place, and they are up to date on their annual inspection. Replace if needed.
Fire Extinguisher (2/unit) Visual Inspection (Seal, UL, Damage)
Inspection Date Tag 1:
Inspection Date Tag 2:
Conduct the following Trailer Checks and Write the expiration Date. Ensure all paper work is returned to trailer bubble.
Federal Inspection (Annual)
Federal Inspection (Annual) Expiration Date
State Inspection (BIT)
Registration
Registration Expiration Date
Check Grounding and Bonding (10 OHMS or under)
Unit
Propane
Generator
Generator
Is the Oil change overdue?
if the answer is "oneOf [Yes]"
Red Tag the Generator. Notify the Shop Manager. Put in a WO Request in MaintainX.
Generator Hours:
Meter name
Unit
Is the oil level and the coolant level good?
if the answer is "oneOf [No]"
If levels are low fill reservoirs before starting up the generator.
Check spill containment and drain any liquid.
Inspect for any Fuel/Oil/Coolant leaks.
if the answer is "noneOf [PASS]"
If leaks are found, red tag the generator, inform the shop manager or supervisor, and put in a WO request in MaintainX to address the leak.
Generator #
Check that the SO cord is connected and snug inside of the panel before energizing power to the unit.
Generator Startup
Are there any Active Alarms on the Generator?
if the answer is "oneOf [Yes]"
Red Tag the Generator. Notify Shop Manager. Put in a WO Request in MaintainX.
Capsuhelics and Magnehelics
Check All and Re-zero or replace if necessary
VFD's and Power Breaker Switches
Open Panel (No Power On) Check SO Cord for damage. Verify SO Cord connection is tight to breaker in panel before turning on Generator. Verify Generator is connected correctly. Check for any other issues.
Process Blower and VFD Panel
Motor Rotation
Process Blower
Observe rotation of Process Blower
Combustion Blower
Observe Rotation of Combustion Motor or Blower
Vaporizer Startup
Safety: LP gas is extremely flammable. Monitor continuously with a PID/4-gas meter and route relief vents at least 25 ft away from personnel and ignition sources.
Clear the area and check for leaks – remove all combustibles from the vaporizer area and run a PID/4-gas scan of the cabinet, fuel train, and regulators.
Both Blowers must be on before the following steps can be performed:
EMECS Startup
TOTAL EMECS Unit Hours (Do not put the hours ran during the Test Fire)
Meter name
Unit
Once at Set Point Check all Parameters
EMECS Integrity Checks
Above 400F Degrees
Process Isolation Integrity Test: While Temperature is Below 400F, Open Manual Process valve and Verify No Inlet Vacuum
Manual Process Valve Integrity Test: While Temp is above 400F, Verify process Valve Opens. Then Verify No Vacuum While in Manual Process Valve is Closed.
High Temperature Limit Controller: Lower setpoint below operating Temperature and Observe if the Unit Shuts Down.
if the answer is "oneOf [FAIL,FLAG]"
Determine Why? Move the Setpoint Back to 2000F and Press Reset Twice.
DA/FA Torque Check: Check Torque Values on All FA'S and DA'S.
Verify Torque Values on FA and DA according to the photos below. Record your Torque Pattern and Torque Value's for each pass Below. If you do not Torque properly there is a likely chance of a leak developing. Do NOT bypass this step.
EMECS Operational Checks
When the Unit is at Set Point Check the Following
Pressure Gauge Upstream of MAR90 (PSIG)
Pressure Gauge Downstream MAR90 (PSIG)
Inlet Flow (Unit Maxed Out)
Total Flow (Unit Maxed Out)
Detonation Arrestor Inlet Pressure (with 50' Air Ducting Hose Attached to the DA)
Detonation Arrestor Outlet Pressure (with 50' Air Ducting Hose Attached to the DA)
Flame Arrestor Inlet Pressure
Flame Arrestor Outlet Pressure
Interlocks (Safety Shut-Downs and Alarms)
High-High FA Inlet/Outlet & Firebox Inlet Temperature
FA Backflow-Differential Pressure
High-High DA Inlet/Outlet Temperature
Low-Low Fuel Pressure (Pilot & Enrichment Lines)
High-High Fuel Gas Pressure
Low-Low Combustion Air Pressure
Combustion Blower Failure
High-High Process Air Pressure
Process Blower Failure
High High Firebox Temperature
UV Scanner #1
UV Scanner #2
EMECS Shutdown
Cooling and Shutting Down the Unit
Unit End Hours
Meter name
Unit
Verify Spare Chart Recorder Battery in Panel.
Verify Chart Recorder Settings Sticker are on the outside of the Chart Panel.
if the answer is "noneOf [PASS]"
Get with the Shop Manager and install the Sticker on the panel.
Meter name
Unit
Inspect Air Bottles
Does the unit have Air bottles for the process inlet?
if the answer is "oneOf [Yes]"
Checks
Pressure good and above 500 PSI?
if the answer is "noneOf [PASS]"
Have bottles filled. Inform Shop Manager.
While the bottles are online perform a snoop check for leaks. Once leak check is completed block the bottles back in.
Notes
Notes or Record any Changes Made to Equipment
360 Walkaround Inspection
No Tools or Debris on Deck, Equipment is Secured, all Boxes are Orderly, and Inspection and Registration are Current
if the answer is "oneOf [FAIL,FLAG]"
What issues were found during the 360 Inspection?
Verify Carseal is installed on Main Panel.
