Troubleshooting
Check strainer clean
Check system for air rate
Check pump for operation –220V AC = 1 Amp
Check system / Check pump
Check system
Check system 5V DC- input signal
Input 220V AC
N/C contacts
Check gas connection
Check gas valve
Check tube for connection
Check flue for blockage
Check gas valve 220V AC
Check gas pressure
Check fan for operation
Check switch, flue for obstruction
Re - connect
Check voltage Pin #15&5 on 21Pin connector,
main controller 5V DC
Re - connect
Check voltage Pin #19&8 on 21Pin connector,
main controller 5V DC
Check fan for operation. Input voltage 7 – 40V
DC. Red-Black wires
Check fan for operation
Check tube connection
Check voltage 5V DC
Check flue for blockage
Check flue termination - relocate
Voltage 5V DC
Check gas pressure
Check gas valve
Check fan for operation
Check tube on air flow sensor
Check air flow sensor – 5V DC
Check flue for obstruction
Check voltage – 5V DC on Pin #10 on 13 pin and
Pin #17 on 21 pin connectors
Re – connect
Check gas supply
Check voltage 5 – 20V DC
Check connection from t-stat to unit
Replace t-stat or micom controller
Check for pump operation 220V AC, approx 1A
(dependent on flow rate)
Check fan for operation
Check rotation
Check setting especially
