Wood Gasification Hydronic Boiler
Safety
Normal hydronic safety valves are to be fitted as well as suitable expansion capability to the wood gasification hydronic boiler. Therefore a wood log safety flush valve, a 3 BAR pressure relief valve [PRV] and a quality air dirt remover.
Routine cleaning should be continued
You must brush out your KK Series wood gasification boiler. Do this AFTER moving the heat exchanger handle back & forth a few times. Dust in the galleries will drop into the lower chamber. Brush & vacuum the two chambers.
Check the quality of the wood
Hardwood serves as the best fuel for your wood gasification hydronic boiler such as ash, oak, beech, and maple. Moisture content 12% to 20%, measured with a moisture probe. STIHL outlets and Bunnings sell these. https://www.bunnings.com.au/crommelin-moisture-meter_p0911078
Servicing of your boiler
Servicing your wood gasification hydronic boilerboiler annually will ensure it keeps running optimally for as long as possible. Read the user guide for details, if unsure ring Kroll on 1800 805 243. As a rule, it is good to service your boiler in September or October so that it is ready for heavy use during autumn and winter.
Creosote Treatment
Luv Ya!
Try burning some SootLoose to reduce cresote buildup. Once a month.
Periodic Servicing
Cleaning period of your wood gasification hydronic boiler depends on plant features, fuel and combustion parameters so after first commissioning please clean the boiler heat exchange surfaces once a month, if they need any cleaning. After a few cycles you can decide the period of cleaning you will need.
Do not add any additional fuel and wait up to all the fuel finishes burning. See https://kroll-heaters.com.au/user-guides-information/kk-series-operations-maintenance/
Wait for cooling the boiler (min 2-3 hour)
Stop the circulation pump
Disconnect the main power supply then dismantle the back side flue gas top door [see 4.11 Pg 26] and clean all
the flue pipes. Dismantle the bottom back door [see 7.1 Pg 29] and clean
the flue box.
Check the flue between boiler and chimney, clean if necessary. Control
the chimney.
Then put back all the dismantled part in its proper place in reverse order.
