Mertik GV60 – Troubleshooting Quick Guide

Balanced flue gas fires fitted with Mertik GV60 gas control system:

1. Acoustic Warning Signals:

• One long beep
  • Kill switch OFF (0): Flip Kill switch to (I).
  • Wiring not complete: Check wiring thermocouple circuit.
  • 8 wire cable defective: Check/replace 8 wire cable.
  • Micro switch defective: Change gas valve.
  • Sync not OK: Perform new sync remote<>receiver.
• Three short beeps: Replace batteries or mains power supply.

2. No Reaction from Remote/Receiver:

• Power supply/batteries: Check power supply.
• No sync between remote and receiver: Perform Sync procedure.
• Distance between remote and receiver: Re-position receiver.
• Damaged receiver: Replace receiver.
• Damaged remote control: Replace remote control.

3. No Pilot Gas (no clunking sound):

1. Check wiring and interrupter in pilot circuit.
2. Check/replace 8 wire cable remote<>gas valve.
3. Check ground wire under torx during 1 spark stop.
4. Replace receiver.
5. Replace gas valve.

4. No/Bad Spark:

• Disconnected spark wire: Check spark cable connections.
• Short between cable and metal: Check if cable is free from metal parts.
• Bad spark plug: Check spark plug for fractures and replace.
• Distance between spark plug and pilot head: Ensure distance is approximately 4mm.

5. Pilot Flame Hard to Ignite:

• Issues with mains gas supply pressure: Adjust main gas supply pressure or pilot flame pressure.
• Air inside pilot tube: Purge complete gas lines.
• Blocked injector: Clean or replace pilot injector.
• Issues with pilot flame gas tube: Check and purge.
• Damaged pilot flame head: Check/replace if necessary.

6. Pilot Drops After Ignition:

• Issues with pilot flame not heating thermocouple tip:
  • Check gas supply pressures.
  • Check pilot flame injector and pilot gas tube.
  • Purge pilot lines if air is inside.
  • Check premix openings.
  • Verify wiring connections.
  • Measure circuit voltage (should be a minimum of 4.5 mV).
  • Check thermocouple.
  • Replace gas valve if DC magnet unit is bad.

7. Pilot Drops in a Closed Fire:

• False air issues: Check for gasket/leakage and ensure pressure hatch is fully closed.
• Main flame interference: Check restrictor/baffle status as per the installation manual.

8. Pilot/Main Flame Drops:

• Check main gas supply lines and pressure.
• Check power supplies.
• Verify fire/flue system specifications.
• Ensure flue connections are secure.

9. No Main Burner Start-Up:

• Gas valve setting: Ensure the big knob on the gas valve is set to ON.

10. Delayed Ignition of Main Burner:

• Obstructions: Check the log/stone positions.
• Check and adjust flame pressures.
• Clean main burner portholes.
• Verify log positions against the manual.

11. Low Main Flame:

• Gas supply issues: Check and correct mains gas supply pressure.
• Check and adjust burner pressure.

12. Main Flame has No Adjustability:

• Adjustment issue: Check low set adjustment and correct as per manual.

13. DB Double Burner Not Working:

• Bad step valve: Listen for a clicking sound, push the ++ button on the remote several times, and replace step valve if needed.

14. Sooting Fire:

• Transport and setup issues: Verify all specs and positions against installation manual.
• Pressure issues: Adjust mains gas supply.
• Check and clean blocked burner portholes.
• Verify and correct main burner and decorative item setups.
