TROUBLE SHOOTING
1) PROBLEM: NOT ENOUGH HEAT OUT OF THE APPLIANCE.
A) If the appliance reaches operating temperature (200°F) and draft fan shuts off , it is working properly. (If draft fan
does not shut off , see Problem 4). Possibly, the appliance is undersized for the required heat load.
B) Ensure that the joints in the hot air duct are tight.
C) Check and clean the return air duct.
D) Replace the air fi lter.
E) Check for furniture blocking the cold air return vents.
F) Verify that the fan limit control is properly set.
G) Adjust the draft blower damper to allow more combustion air.
H) Clean the fi re box walls to improve heat transfer.
I) Check for excessive ash buildup.
J) Ensure that the air fl ow baffl
es (if used) are installed properly.
K) The fuel quality might be poor. Split, seasoned, hardwoods are recommended. Contact your installer or system
designer for further resolution.
L) Check chimney for blockage.
2) 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) Verify that the fuel is properly seasoned (20-25% moisture content).
C) Burning small pieces of extra dry wood can cause creosote. Try burning large pieces of wood for a few days.
D) If problem persists call your installer or local ROYALL Representative.
3) PROBLEM: DRAFT BLOWER RUNS CONTINUOUSLY
A) Set the thermostat at the lowest setting. The draft blower should stop if the room temperature is higher than the
thermostat setting. If the draft blower is still running, go to step B.
B) Disconnect the thermostat wires from the fan control center. If the draft blower stops, then either the thermostat
or the thermostat wiring are defective.
C) If the draft blower continues to run, replace the fan control center (the relay is probably stuck in the
closed
position.)
4) PROBLEM: DRAFT BLOWER DOES NOT OPERATE.
A) Install a jumper between R and G on Fan Control Center- if draft blower runs, either thermostat or thermostat
wire is bad.
•
Turn master switch off .
B) Jumper limit side of fan control center (caution 115 Volt is present)
• Turn Master switch on.
• If blower runs the furnace is either too hot or fan limit control is bad
• If furnace is not over heated than replace draft blower.
5) PROBLEM: SMOKE “PUFFS” FROM THE UNIT
A) Wood may be too wet or green. Try mixing woods.
B) Check for obstructions in draft path (blower, chimney connector, chimney).
C) A partially clogged chimney or exhaust plenum may be restricting air fl ow in the appliance.
