GAS FIRES USING MERTIK GV60 GASCONTROL
Function
Possible cause
Solution
1. Acoustic signals
1 long beep > reset switch OFF (0)
Set switch to (I)
1 long beep > connections not complete
Check connections in thermocouple circuit
1 long beep > 8-core cable defective
Check connections in connector/replace 8-core
cable
1 long beep > micro switch defective
Replace gas valve
1 long beep > Sync not OK
Carry out new sync procedure for remote control
<> receiver
3 short beeps > power supply
Replace batteries or 6-VDC adapter
2. Spinning/rattling gas control knob
8-core cable defective
Check connections in connector/replace cable
Micro-switch defective, blocked
Check and replace gas control valve
3. No reaction remote control/receiver Power supply problem
Check batteries/6-VDC adapter
No sync remote/receiver
Carry out sync procedure
Distance between remote control/receiver
Change position of receiver
Defective receiver
Replace receiver
Faulty remote control
Replace remote control
4. No pilot light gas
GV60 DC magnet unit does not open (no clicking
noise from gas valve)
Check wiring and breaker on thermocouple circuit
Check/replace 8-core cable between remote
control and gas valve
1 x sparks and stop: check ground cable under torx
gas valve
Replace receiver
Replace gas valve
5. Poor/no spark
Spark cable loose
Check spark cable connections
Short circuit between cable and metal
Check whether cable is free of metal parts
Poor spark candle
Check spark candle for fractures, replace if
necessary
Distance of sparkling candle to pilot light head
Check distance is approximately 4mm
6. Pilot light difficult to ignite
Gas supply pressure too high, nervous flame
Adjust gas supply pressure or adjust the pilot light
pressure using the gas valve
Gas supply pressure too low, short flame
Adjust gas supply pressure, check gas pipes, or
adjust pilot light pressure using the gas valve
Air in (pilot light) pipe, flame on/off
Blow pipes through, make air-free
Injector blocked
Clean or replace pilot light injector
Blocked/curved pilot light pipe
Check & clean pipe
Pilot light head damaged
Check & replace pilot light
7. Pilot light goes out after ignition
Small pilot light, no flame on thermocouple tip
Check gas supply pressure, possibly too low
Check pilot light injector and gas pipe
Nervous pilot light flame, no flame on
thermocouple tip
Check gas supply pressure, too high, adjust
Adjust pilot light pressure on gas control block
Air in pipes - vent
Lazy pilot light, no flame on thermocouple tip
Check premix opening on pilot light, must be open
Poor connections in thermocouple circuit
Check cables/breaker in thermocouple circuit
Check thermocouple connections in gas control
block, do not over-tighten.
Measure thermocouple circuit voltage - 4.5mV
minimum
Bad thermocouple
Check open circuit voltage of thermocouple
(18-30mV), replace if necessary
Poor DC magnet unit in GV60
Replace gas valve
8. Pilot light goes out when the
fireplace is closed
False air along pilot light holder/gasket
Check pilot light holder and gasket for leaks
False air hatches
Check pressure hatches/gasket is completely
closed
Main flame causes pilot light to go out
Check restriction/baffle in accordance with
regulations
