The hopper and furnace top will be hot during operation; therefore, you should always use some type of 

hand protection when refueling your furnace.  

Never place your hand near the auger while the furnace is in operation.

In the event of a 

power outage

, the furnace WILL

 NOT

 function.  It is very important that unit be vented properly

, as the 

natural draft is needed to clear the smoke from the furnace during a power outage. In case of power outage, remove any

If the furnace has cooled-of

f, it will reset to its 

“OFF” 

condition.  

At this point, you may press the 

“ON” 

button to 

begin a new start-up sequence.

NOTE: 

The unit will also shut down in the event of an draft fan failure; if this is the case, the unit will not re-start and yo

SAFETY

 AND CONVENIENCE FEA

TURES

Y

our 

King 

incorporates a 

safety pressure switch 

that helps ensure proper operating conditions before feeding fuel to 

the burn pot.  Because the furnace works using an induced draft pressure, the furnace will not continue to operate if the 

viewing door is left open, if the draft fan fails or if the exhaust system is blocked.

The 

temperature limit control 

will prevent your furnace from operating at abnormally high temperatures. Should the 

furnace temperature begin to approach the factory pre-set limit, the temperature limit control will automatically slow down 

the auger feed rate until the temperature returns to a normal condition.  Both room air fans will also operate at full  speed 

until the furnace returns to normal operating temperatures.

Therefore, it is important that the exhaust 

system be 

inspected and cleaned at least monthly 

during the burning season.

 Be aware

less creosote is deposited, and that weekly cleaning can be necessary in mild weather

, even though monthly cleanings 

can be enough in the coldest months. 

Check the clean out tees periodically to determine the required cleaning schedule. 3 or 4-inch chimney brushes are 

available for chimney cleaning. If the exhaust system or outside air pipes have screens on them, frequently clean the
