1.

 If starting after an empty hopper, turn Feed Adjuster 

to “TEST” 

(for one 60 second cycle). This will charge pellets 

into the auger tube and also allow you to check the motors 

for operation. Figure 4.5.

NOTE: The auger motor will not operate with the furnace 

door open.

2. 

Turn Feed Adjuster to #4.

If this is your first fire, or you are trying different pellets, set 

the feed adjuster to #4, Figure 4.6. This is a conservative 

number and will probably need to be increased if maximum 

BTU output is desired. After you know a feed rate setting that 

works well for your application, use that setting.
3. 

Flip the Igniter Switch up 

into  the  “AUTO-LIGHT” 

position, Figure 4.7.
