11. After the ionization current is being sensed by the monitoring electrode (after the
flame is lit up), check the voltage on the clamps of coil #2 (the system operates
properly at voltage of 0.9 – 1.5 V).

•
Disconnected electrode
conductor
•
Improve connection
•
Damaged electrode
•
Check - replace
•
Damaged spark generator
•
Check - replace
•
Run-down battery or damaged
hydro-generator
•
Check -replace
•
Badly adjusted micro-switch
•
Adjust the micro-switch by screwing
down the bolt placed on the micro-
switch lever. Make sure that after
adjustment there is no sparking when
there is no water flow..
•
Plugged water filter.(limited
water flow)
•
Remove impurity, clean, replace
1.
Lack of spark
(lack of ignition
during water
consumption)
•
Damaged elements in gas-water
unit
⇒
Damaged water membrane
⇒
Damaged control mechanism of
gas valve head
•
Replace gas-water unit or damaged
elements
•
Lack of gas supply (damaged
electrode)
•
Open the manual gas control valve
before the heater
•
Air in the gas line
•
Bleed the air out
•
Damaged ignition burner
•
Replace
2.
Ignition burner
does not light up
from the spark
•
Run-down battery or damaged
hydro-generator
•
Replace
•
Disconnected conductor of
supervision electrode
•
Improve connection
•
Damaged supervision electrode
•
Check -replace
•
Damaged spark generator
•
Check -replace
3.
Ignition burner
lights up, main
burner does not
light up
•
Damaged pressure differential
valve
•
Check -replace
4.
Attempted
ignition without
water flow
•
Badly adjusted micro-switch
•
Adjust the micro-switch by
unscrewing the bolt on the micro-
switch lever. Make sure that after the
adjustment there is no effect of
ignition delay while starting the
heater.
