Air fuel mixing for Powerflamer natural stove

Customer (PF13LQN120): 

I can’t see a way to adjust the air mix on the Powerflamer 120 quick connect. There is a galvanized 3/8 pipe the attaches directly to the burner, but no air adjustment. Can you point to the air shutter for me?

For PF13xQN120 natural gas stove, there is no air/fuel mixing wheel.   Individual jet burner on the burner ring mixes themselves.  Do you have soot problem?

Customer

Yes, the burners produce a lot of soot on the bottom of the wok.

The jet burners (16 in total) burn cleanly if their holes are not blocked by spider web or things.  So please check if all jet burner center holes plus their side holes (to let air in) are all not blocked by anything.

Then limit the pilot flame length to around 0.5”.   If the pilot flame is allowed to be too long, it will not burn clean and produce soot.  Let us know any update.

Customer

Thanks, I will try.  The pilot flame is quite long at fully open.  I’ll limit it and see if that helps.

Only difference between PF13LQN120 & PF13LFN160 is gas connect method?

Inquiry: 

Hi there,  Is the only difference between the PF13LQN120 & PF13LFN160 the gas connect method; quick connect vs. direct?
 
If so, is everything else identical between on two models (the burner, size, height, etc)?
 
I don’t understand how there can be a 40k BTU difference in output if the only difference between the models is quick connect vs. fixed.
 
What size are the black pipe fittings on the stove? They look like1/2″ from the photos.
 
Outdoorstirfry: 

Our fixed installation stove allows more gas to pass through to the burner.   Both 160K and 120K numbers are our actual measurement data points.   We don’t have more photos than that available from our web site.   Usually fixed installation is for serious customer who need to meet local code requirement by hiring a licensed plumber (~$200/Hr rate) and proper code compliance hose.   For regular home cooking, most people should find 120KBTU one is quite sufficient.   The black pipe on our stove is 1/2″.
