Sierra Products EF5001B-AL Maintenance Procedure, Soot and Fly-ash Formation and Need for Removal

4.Clearance to combustibles may only be reduced by m eans approved by the regulatory authority.

5.Store pellet fuels in a dry area away from unit. Do not store fuels within the space heater installation clearances or within the space required for charging and ash rem oval.

6.Adequate ventilation air is required to operate this heater. During operation the heater draws air for com bustion which can be assisted by the installation of outside com bustion air inlets. However, certain weather conditions such as icing or use of kitchen exhaust fans may im pact and reduce the effectiveness of vents. It is im portant to note that room air starvation well negatively im pact the operation of the heater.

7.If power outages with battery backup or room air starvation occurs during operation of heater, sm oke in the house may result. This may trigger sm oke detectors if they are installed.

MAINTENANCE PROCEDURE

CAUTION: MOVING PARTS MAY CAUSE INJURY, DO NOT OPERATE WITH REAR COVER REMOVED.

WARNING: RISK OF ELECTRICAL SHOCK, DISCONNECT ALL POWER BEFORE SERVICING.

ALWAYS TURN YOUR Heater OFF & LET IT COOL BEFORE CLEANING.

Soot and Fly-ash: Formation and Need for Removal.

The products of combustion will contain small particles of fly-ash. The fly-ash will collect in the exhaust venting system and restrict the flow of the flue gases. Incom plete com bustion, such as occurs during startup, shutdown, or incorrect operation of the room heater will lead to some soot form ation which will collect in the exhaust venting system . The exhaust venting system should be inspected at least once every year to determ ine if cleaning is necessary.Your EASYFIRE Pellet Heater requires routine m aintenance for maxim um performance and is mandatory for the warranty to rem ain in effect. The following procedures should be studied carefully and perform ed regularly as indicated:

1.Fly Ash: Some ash will accumulate in the heat exchanger, firepot and flue and should be cleaned out on a regular basis for best efficiency and safety.

W hen the heater is shut down and cold, you should:

a.Open door and rem ove clean out slide cover. To rem ove, sim ply slide up and out from retaining angle bracket (Figure 10). Clean one side at a tim e. W ith one slide cover rem oved, leave door open and turn control knob to the "CLEAN" position. Let heater run until ash in fire pot area is vacuumed out by heater fan. Turn off and replace cover. Rem ove rem aining cover and repeat procedure for the other side. The tee cap on the vent pipe should be cleaned out after this procedure.

b. Rem ove firepot by lifting up and out, it may be brushed out or vacuumed. Firepot should be cleaned daily. Make sure holes in pot are not clogged. The area around and below the pot should be checked every five or six days depending on how many hours a day you are burning your heater and the quality of the pellets being burned. (After a few days you will be able to determ ine the frequency needed for clean out.)

c.Scrape pellet feed chute with putty knife to rem ove hardened material on which sawdust can accumulate.

d. The tee connector on the vent pipe must have a clean out cap and this must be checked every four to six weeks or whenever you utilize the clean out mode on the control dial.

e.Fly-ash can also accum ulate in the vent pipe. Inspect exhaust system frequently to maintain free flow of exhaust fum es and fly-ash. The frequency of clean- out depends entirely on the quality of the pellets, so you will have to initially monitor the buildup in the pellet vent pipe. Those installations going into an
