LIGHTING INSTRUCTIONS

Before lighting your Hearth Focus for the first time, make sure that all items are out of the hopper, ash pan and firebox

area.  

Press the “On” button and allow your heater to run for at least 4 minutes, to check for proper operation. Once your

heater is started, you will notice the draft fan starts immediately. If you press the “Heat Setting” button up, the draft fan
changes speed, increasing speed the higher the heat setting. After 3 minutes, the auger and agitator will start rotating.

Note:  The room fan will not operate at this time, as a temperature of at least 110 degrees must be reached before

operating.  If proper operation of your heater is confirmed, you can add fuel to the hopper and allow the auger to purge the

fuel to the firepot.

TO START:
Turn the Heater to the “OFF” position and place a small handful of wood pellets or fire starting pellets (Pellets that already

contain fire starter) in the firepot.
Squirt only a small amount of fire starter gel on top of the wood pellets (NOT necessary if using fire starting pellets).
Light the fire starter and wait approx. 1-minute for it to start actively burning.
Press the “On” button, adjust the heat setting to read  “Hr-2” and  pull the damper out approximately 1.5 inches for this

heat setting. This will automatically match your feed rate with the proper combustion air. As you increase the heat

setting, your feed rate and combustion air increase together.
NOTE:  Even if you are burning corn or other fuels in your unit, wood pellets make an excellent source of

starter fuel.  Corn takes too much starter to get lit and up to temperature.
Three minutes after turning the stove “On”, the auger will begin feeding fuel into the firepot along with the agitator

turning. You should have the starting fuel completely burning in the firepot as the agitator rotates. NOTE: If the starting

fuel is not burning hot enough, you may see the fire begin to go out as new fuel is being added. If this occurs, pressing

the “Auger Delay” button will allow the auger to pause for 1 minute.  Pressing the “ON” button will resume the auger if

1 min. is to long.  If not enough fuel is the reason for not burning, pressing and holding the “ON” button will allow the

auger to run continuosly until you release the button.
Once the fuel starts burning aggresively, you can adjust the heat setting to your desired range. Make sure that you pull

the damper out fully for heat ranges above Hr-4.
As you begin to have better understanding of how the heater operates and the amount of heat you require, you can adjust

the heat settings up or down to your satisfaction.
Never use gasoline, gasoline-type lantern fuel, kerosene, charcoal lighter fluid, or similar liquids to start or

‘freshen up’ a fire in this heater.  Keep all such liquids well away from the heater while it is in use.
Overfire Protection - If the heater is being overfired, burned too hot, the heater will automatically shutdown to avoid

damage to components in the heater.  Refer to “Lighting Instructions” for proper use.

Turning the stove off
Pressing the OFF button will cause the stove to enter a shutdown mode.  If the stove has reached operating temperature, the

OFF Indicator will blink until the shutdown procedure succeeds in lowering the stove temperature.  The Room Fan will stay

on to cool the stove, and the Exhaust Fan will stay on to remove smoke and heat from the combustion chamber.  The Agitator

will stop.  The Auger will bump the fuel out of the auger every few seconds to prevent the fuel in the auger from burning.

Once the temperature of the burn chamber falls below about 100 degrees F and the pressure switch detects that the door

is closed, the fans will stop and the Auger will run for a few seconds to purge the auger system of any burned fuel.  At this

point, the OFF Indicator will go out and the stove will turn completely off.  If during burning, the stove has reached at least
