OPERATION
NOTE:
Ambient flame burners produce both a blue and yellow flame. An excessively high yellow
colored flame may be caused by airborne dust, dander, pet hair, etc. Additionally, an excess amount
of Mercaptane in the fuel can result in an orange or yellow colored flame.
When this heater is set for use on propane gas, the upper one third of the flame may be bright yellow.
When this heater is set for use on natural gas, a slight yellow tipping of the flame may occur.
