When I first attempted to insert the regulator into the propane connection in the side of the stove, the regulator stem would not go in all of the way. I determined that the cause was that the internal propane connection was not lined up with the hole in the side of the stove. I removed the stove drip plate and properly aligned the propane stem with the hole in the side of the stove and that solved that issue. While I did not have any issues with this repair, I would think that many customers would not attempt this fix, this is a manufacturing and quality control issue.
The next issue I encountered was that the knurling on the brass connection nut on the regulator stem was basically non-existent. This makes it very difficult to tighten the nut to the correct torque to prevent a leak at this joint, this again is a manufacturing/quality control issue.
When I assembled the stove and connected it to a propane source and attempted to light the stove, no propane would come out of any burners. I had to close the valves on the stove, close the valve on the propane source, remove the propane source several times to get the regulator to provide propane to the stove. Once I finally got propane running to the stove, and I had one burner running, as soon as I turned on a second burner, the first one would go out. I had to close both burners, then turn them on simultaneously to get two running at the same time. Over time using the stove, this issue did get better. This is a regulator manufacturing/quality control issue.
While the stove valves have approximately 180 degrees of motion, only about 30 degrees or less control the flame from off to full. Attempting to adjust the flame to anything less than medium is very difficult if not impossible, once you get the flame to low, and let go of the valve knob, the flame jumps to medium, this is a design issue.
The next issue is the design of the stove its self, the stove is advertised as a three burner stove, but its design will not allow three pots of any reasonable size to be used simultaneously. You have to align the three pots in a triangular shape, which does not allow them to have sufficient contact with the burner flame to heat them reasonably. Only two pots can be used simultaneously, which completely negates the value of a three burner stove, the main reason I bought the stove. The stove needs to be at least 6-8 inches wider to use 3 burners.
I noticed that most of the competitors in this propane stove/size have as a standard, a stainless steel drip pan and burner rack, this unit has neither.
In good conscious I cannot recommend this stove for purchase, considering Coleman’s reputation for superior design/reliability, and dependability, this unit is a very big disappointment.
