Aeration adjustment
As described in section 11, for natural gas appliances, the burner aeration is adjustable. For the vast majority of installations,
no adjustment will be necessary. However, in a very few instances, performance may be improved by sliding the shutter to
adjust the aeration by (See figure 35). Evaluate the aeration only after the unit has warmed up – approximately 15 minutes.
Increasing aeration will cause the flame to appear more transparent and blue making the ceramic fuel effects glow more.
Decreasing aeration will cause the flames to appear more yellow or orange making the fuel effects glow less.
Too little
aeration may result in black carbon forming and dropping into the firebox.
