Eko-Vimar Orlanski Orlan - Boiler Shutdown and Air Inlet Settings

Warning!
The yellow “no fuel” light indicates when the boiler needs to be reloaded.
Boiler Shutdown
The boiler turns off in two ways: manually when the power switch on the controller is turned off, or au-
tomatically when the wood supply has burned out. NEVER turn the controller off for extended periods
when the boiler contains burning fuel, as doing so could cause to it overheat. If you want to shut down
the boiler, set the controller setpoint to minimum and let the fuel burn out.
Operating Temperature
Maintaining the proper temperature of the water in the boiler during operation is very important. For
proper gasification to occur, the boiler water temperature should be 140F or greater.
At times, such as when there is a large call for heat, the return water temperature may become too
low. This can result in poor gasification and decreased efficiency, as well as creosote buildup in the
gasification chamber, heat exchanger tubes and chimney. Low temperature return water entering the
boiler can also shorten the life of the boiler. The return water temperature should not be allowed to
drop below 140F. This can be achieved with a properly installed 3- or 4-way mixing valve.
Primary, Secondary and Blower Air Inlet Settings
A critical phase of successfully setting up an EKO boiler for operation involves setting three air supply
openings, as listed below and shown in the photographs on the facing page:
1. Primary Air Setting
2. Secondary Air Setting
3. Blower Air Inlet Setting
The following chart will help you determine how to set each one, depending on the model of boiler
and the variables affecting its operation, specifically wood moisture content and chimney draft:
