[QUOTE="Rob_the_rich, post: 383565, member: 8419"] Aah ok, I was wondering where the condense was that Andy mentioned, I had an earlier model's instructions. I have the right instructions now; " Gas present and at correct pressure? Gas valve – Check that there is 35V d.c. to each solenoid – Check the resistance of each solenoid: Top solenoid = 380 Ω ・} 10% (342 - 418 Ω) Bottom solenoid = 190 Ω ・} 10% (171 - 209 Ω) Combustion CO2 level. Flue condition. – Blocked flue? Blocked condensate pipe or frozen condensate. Gas valve adjustment. Ignition electrodes/harness/connections. – Check for condition and resistance of leads (approximately 2100 Ω) Otherwise replace control board" The easiest thing to check is that the plastic condensate pipe is not blocked, it could be frozen outside,. See if you can disconnect it at the boiler and blow down it. [/QUOTE]
