Problem

Reason

Investigation/Solution

Temperature rises 

too high (above 

temperature 

setting) in first 

15-20 minutes of 

operation

LID CLOSED TOO SOON 

AFTER STARTUP.

• After turning to Smoke for startup, don’t shut the lid until lots of 

smoke is released and the fire has burnt for a few minutes. 

• Shutting the lid too early results in the large initial quantity of 

pellets releasing lots of heat which easily overshoots lower 

temperature settings.   

• Leave the lid open for up to 10min (especially in hot weather) 

during startup if temperature overshoots after closing the lid. 

• Note that leaving the lid open for too long (>10min) will also 

cause issues as the the controller will continue to dump more 

and more pellets to try and achieve the target temperature. 

Excessive or 

discoloured smoke 
or  
Grill not able to 

reach desired 

temperature

MOIST PELLETS

• Empty the hopper of wood pellets. 
• Run the grill at 232

o

C to push out remaining pellets in the augur 

tube.  

• Turn the controller dial to Shut Down.   
• Once cooled down, vacuum out the hopper and fire-pot. 
• Pour in dry pellets (only as many as required for cooking) and 

then follow the Initial Startup Instructions. 

Noisey Auger

LONG PELLETS

• Occasional clunking and squeaking sounds are normal and are 

due to the auger breaking through longer pellets.  

• Try using shorter pellets.

Lots of smoke 

appearing from the 

Pellets in Hopper.  
  
Tiny amounts of 

smoke may appear 

in windy conditions 

which is normal.

WOOD DUST in AUGER 

TUBE and HOPPER  
or  
HIGH TEMP OPERATION 

WITH LID OFTEN OPEN 
or 
HIGH TEMP OPERATION 

IN WINDY CONDITIONS 
or 
DIRECTLY TURNING 

FROM HIGH 

TEMPERATURE TO SHUT 

DOWN

DO NOT pour any water into the Hopper 

Steps to Take 

• Open the grill and hopper lids. 
• Turn the controller dial to Smoke setting (power switched ON). 
• If after another 10 minutes there is no more smoke coming from 

the hopper, turn the grill to shut down, or back to the desired 

temperature to continue cooking. 

• If the smoke does not stop appearing from the hopper after 10 

minutes, remove all the pellets from the hopper right down to the 

auger (use vacuum if necessary) and run the controller on High 

until ALL pellets have cleared from the auger tube.   

• Turn the unit to Shut Down.   

Clean the Grill 

• Once the unit has fully shut down and is cool, vacuum out all 

pellets, dust and ash in the hopper, fire-pot, pellet feed tube and 

grill drum.   

• Complete Initial Startup Procedure with clean pellets. 

Future Prevention 

• Avoid pouring the wood dust from the bottom of bags of pellets 

into the hopper.  Very dusty pellets should be sifted before use. 

• Every 15-20kg of pellet usage, let the grill fully run out of pellets, 

so the pellet feed tube is empty.   Then “Clean the Grill” as 

outlined above. 

• After each use, vacuum out the fire-pot and grill drum area of ash.  
• Make sure the chimney cap is not screwed down too much. There 

should be roughly a 0.5cm gap between the top of the chimney 

and the cap.  Also clean the underside of the chimney cap and 

chimney of soot build up.
