4) PROBLEM: WATER TEMPERATURE DOES NOT REACH FAN CONTROL AQUASTAT SETTING. (DRAFT FAN RUNS CONTINUOUSLY.)
A) Wood may be too wet or green. Try mixing woods.
B) Check for obstructions in draft fan.
C) A defective solenoid may cause fl apper on fan not to open when fan comes on.
D) A partially clogged chimney or exhaust plenum may be restricting air fl ow in the appliance.
E) A buildup of ashes in the ash trough can restrict the exhaust of combustion air.
F) A buildup of ashes on top of the grates can restrict combustion air.
G) Heat is being lost through underground pipes. Temperature coming into house should be no more than 2-3°
diff erent than temperature of water leaving the appliance.
H) Appliance is undersized for building being heated.
5) PROBLEM: NO WATER FLOW
A) Air could be trapped in the line.
•
Repeat
fi lling and venting procedure.
•
Temporarily add more water to system to bring pressure to around 25 psi. This will compress any air
bubbles allowing them to more readily move to the air vents.
B) Pump is not running. You should be able to feel the vibration of pump when it’s running.
•
Defective pump - check if installed properly. If installed incorrectly, pump will burn out. With 180° water
circulating through pump, it will be hot to the touch.
•
Pump is not wired correctly. Refer to wiring diagram. (See page 20.)
C)
Pump
fl anges are closed. Flanges are open when screw slot is parallel with the pipe.
D) The system is frozen somewhere.
6) PROBLEM: EXCESSIVE CREOSOTE IS BUILDING UP IN ASH TROUGH.
A) Ash build up above grates or in ash trough area will cause restrictions in combustion air.
B) Appliance may not be burning hot enough.
•
Set fan control Aquastat to 180°F.
•
Set
diff erential on fan control Aquastat to 20° (if adjustable). This will let water temperature drop 20° before
fan is started, causing a longer burn cycle.
C) Verify that the fuel is properly seasoned (20-25% moisture content).
D) Try burning small pieces of extra dry wood for a few days. Large pieces of wood can cause creosote.
E) If problem persists call your installer or local ROYALL Representative
