Sierra Products EF-4001B operating instructions HI TEMP/FLUE and Trim Indicators

deactivate the timer you will have to start over by turning the knob to off and then back to FAN or LOW .

The EASYFIRE will automatically switch to 12 volt backup provided you have the 12 volt option installed.

2.P ro ble m : The heater was lit and burning properly, then suddenly it stopped feeding pellets.

Solution: a) C heck pellet supply in hopper. If em pty, fill and follow start-up procedure as outlined in the beginning of this manual. b) O ccasionally, a foreign object, debris or an excessive amount of sawdust can enter the feed mechanism and jam the feed chute. If this happens, you must em pty the hopper and check the feed chute to see what is causing the jam. Rem ove any foreign material or object and re- start the heater. CAUTION: Keep fingers and hands clear of feed mechanism when heater is on.

3.P ro ble m : The fire was burning well and then it began to overfeed pellets and started backing up into the pellet feed chute, smothering the fire.

Solution: W hen the pellets are overfeeding, it usually

m eans that the air flow has been red uced. Ch eck the F ire Pot air intake holes to be sure they are clear. Check to see if Fire Pot was pro perly seated in pot tray. Check to see if the manifold may have filled with Fly-ash. If you use a low grade pellet, and clink ers (fused ash and dirt) form in the botto m of the Fire Pot, it will choke the air intake (you might consider ch anging the brand of pellets to one that burns cleaner). You must let the fire go out before rem oving and clean ing the Fire Pot.

Never vacuum out the heater w hen the heater is in operation! The hot ashes can lodge in your vacuum cleaner and cause a fire!

You must clean the manifold regularly in order to insure a good air to fuel ratio, thus allowing the heater to "breathe" properly. You must also check the vent pipe and tee to see that they are not clogged and full of ash.

4.Problem: Heater was burning well and then soot began form ing on the glass door.

Solution: Black soot forming on the glass door means that the combustion is not right and the heater needs a good clean out. Some brands of pellets burn much richer than others and you might have to change brands of pellets and/or have the air/fuel settings re-adjusted by your dealer. It is normal to have the glass cloud up after several hours of burning but it should wipe off with a good window cleaner. If the glass turns black quick ly, then the heater needs a good clea n out.

5.Problem: W e had a power failure and the heater emitted smok e for about five minutes.

Solution: If the heater emits smoke during a power failure, and you have frequent power failures then we suggest you purchase the battery back-up system. If the

vent pipe is installed according to these instructions the smok e will syphon out of the pipe in most instances.

6.Problem: After several weeks of outstanding perfor- mance, the heater suddenly stopped and the red light under the control knob came on. This light is the Hi Tem p/Flue Indicator Light.

Solution: The Hi-Temp/Flue Indicator light indicates that Fly-ash has built up in the exhaust system and/or there is a restriction in the exhaust/flue system. Check the pipe system for excessive ash and clogging, particularly the vent cap. Remove the clean out cap on the tee and make sure that ash has not blocked the exhaust air flow. This automatic shut down in case of flue clogging is a safety feature and if the shut down occurs it means you have a problem and should consult a service technician and/or clean your pipe and heater thoroughly. If you feel the Fly-ash build up is excessive, we suggest that you try another brand. In moist climates the pellets and Fly-ash can actually absorb m oisture from the air and crea te creosote and a severe clogging problem . Keep this in mind when you store and handle your pellets. The heater warranty does not cover the quality of the fuels used or the way they may be handled either before or after you've purchased them.

7.Problem: I turned off the switch and the heater kept running.

Solution: This is normal. The exhaust blower will keep running until it cools down and then it will autom atically turn off. This can vary by the temperature the exhaust has reached and the temp erature of the cooling air.

HI TEMP/FLUE AND TRIM INDICATORS:

W hen the H i-Tem p/Flue indicator light com es on (red lite beneath control knob) it means that the flue is obstructed or you have a reverse draft and gases cannot exit properly.

Maintenance is required and a thorough cleaning and pipe check m ust be performed.

TRIM button : Underneath the control knob you will find a sm all round butto n that will turn fo rward and reverse . This button can control the fee d m otor in th e LOW position only. By turning the button clockwise you can increase the feed on LOW and by turning it counterclockwise you can decrease the feed in the LOW position.

Move this button carefully! It is designed to fine tune your LOW setting in the event you change brands of pellets and/or live at a higher elevation.
