Today I will try to clear up any confusion on the direction a burner’s holes (or jets) should face (upward or downward).<\/p>\n
First of all, this post is about burners using natural gas.\u00a0 Propane is a whole different subject.\u00a0 If you are using a propane burner, the holes should already be faced properly for that type of burner.\u00a0 So let’s forget about propane(LP) for this discussion.<\/p>\n
Let’s also make three assumptions.<\/p>\n
You will notice when ordering any of our burners that have a polarity (where one burner leg is shorter than the other so it fits nicely into the trapezoid shape of a common fireplace) there is an option to order the burner with holes facing downward or upward and to specify which side (left or right) the gas feed is located.<\/p>\n
NOTE THAT THE BURNER WILL FUNCTION WELL WHETHER THE HOLES ARE FACING UPWARD OR DOWNWARD, so we do not make the option “mandatory” when you place an order.\u00a0 This is very important to know.<\/p>\n
Taking everything above into account, we prefer to face the burner holes downward.\u00a0 Since natural gas rises, the gas pushes down and then rises and spreads before igniting and burning above the surface of the filler material.\u00a0 There is not enough oxygen under the surface of the filler material to allow the gas to burn.\u00a0 It is too rich to burn.\u00a0 Natural gas needs to mix with oxygen in order to burn.\u00a0 Burner holes facing down should give you a little larger flame bed when compared to burner holes facing upward.<\/p>\n
I hope that clears up this topic.\u00a0 As always, feel free to ask for more clarity if something is not making sense.<\/p>\n","protected":false},"excerpt":{"rendered":"
