Troubleshooting
If furnace is not heating:
1. Check fire.
2. Check pump. If pump is not running, shut off power supply to pump and inspect.
3. Check water level. If water is low, inspect for leaks in the system.
4. Check chimney for creosote build-up. If opening is reduced fire cannot burn properly.
5. Check Fan Draft and Draft Flapper. Make sure they are operating properly.
6. Check Fan Switch on ETC to be sure it is ON. Fan Switch should only be off while filling or clean

ing.
7. If water temperature is reading 120° or lower, push Set Button on ETC System to restart Heating
Mode.
Furnace boils:
1. Check fire door. Be sure door was not left open.
2. Check fire door rope. This is the fire resistant gasket around the Fuel Door. Make sure the door
has a tight seal.
3. Check air intake on fire door. Make sure cover closes tight.
4. In extremely warm weather, a smaller amount of wood should be used.
5. Check Auger Head for air leaks and that Ash Auger Head Discharge Door is closed.
NOTE: If furnace boiled water out and air entered lines this could damage pump. Be sure to remove air
from system. (See Filling With Water on page 11.) A hissing sound coming from the pump, in most
cases, means there is air in the system. Check water level to insure that your furnace is full.
If none of these suggestions appear to
solve your problem, contact your dealer.
