why is my new natural gas fire pit flame blue and not yellow?
outside pit has blue flame only, needs to be yellow
Ok, basically every answer here has missed the point. This unit is an OUTDOOR FIRE PIT. They are NOT designed for indoor use, nor are they vented. The burner is designed to create an aesthetically pleasing flame that simulates a real wood fire. To suggest that one would want a solid blue flame on this unit would defeat the purpose of the unit. Again this is an OUTDOOR FIRE PIT, the main concern is aesthetics and not proper combustion (As it pertains to what is traditionally perceived as proper burner adjustment.); it’s supposed to look like a real wood fire people! (Yes, yellow flames and all.) Variations in burner port size throughout the burner, plus allowing the gas to flow through various types of media prior to ignition all create the flame appearance of a wood fire.
I don’t doubt the good intentions of any answer here, but they all provide clear evidence to show that you really need an installer that is NFI (National Fireplace Institute) certified. You can see by the answers that this type of system goes against every grain of common knowledge that an average HVAC tech. has. The entire concept of creating poor combustion in the name of aesthetics is counterintuitive to the common teachings of proper combustion within the heating industry.
With all that being said, and without laying eyes on your installation it would be difficult to say what the problem is. One could mistakenly assume that these units would be installed quite simply. Nothing is further from the truth. Each manufacturer has slightly different methods of achieving the best aesthetics. Here are some of the factors that should be considered before installation.
Capacity of incoming system to meter - Capacity of system between origin and connections to the control valve - Type of pipe - Size of pipe - Length of run - orifice/air mixture - Number of turns - Capacity of valve - Line pressure - Altitude.
Testing of all the above factors is the only method of insuring enough/proper supply to make a full flame pattern.
