Product review (5 stars): Burns K-1 very nicely
I doubt you could find anything for the same expense to equal this unit. BE WARNED: you must ignite the unit outdoors for the first time metals, paint and new wick will emit odors during initial burn-in.

1. Trim the wicks equally.
2. Initially fill to about 20% of capacity/good quality K-1 Kerosene (Lowes or Home Depot) until you are comfortable lighting and operating unit.
3. IMPORTANT: CONTROL THE WICK HEIGHT BY GENTLY PULLING OUT ON THE ADJUSTMENT KNOB, (clockways =high, CCW =low) otherwise the adjuster will latch into position which can be a really exciting event when you have raised the wick to high and then cannot get it to go down!!
4. Do it outside until you are comfortable with the operation.
5. NOTE: the wick feed mechanism is not threaded it is marginally secured to reservoir/tank assembly. Make sure it is secure before lighting rotate CW and press down, it does provide a reasonable fit.
6. This unit is not UL listed. It will require some thought and common sense to safely operate.
7. One more thing, I have observed the unit to creep up after lighting it up from a cold start, be prepared to back the wick down to lower output, could just be a break in issue.

I have been using mine for a couple of weeks now and I am very happy with it, it gasifies k-1 very nicely and produces the beautiful blue color in the chamber column which means the fuel is burning efficiently. For my needs this form of energy is just perfect and is much more efficient than LP. Hat's off to the people who can design and fab these units for so very little.
