with short flames with Control Knob Set
to High Flame (Infrared Flame)
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.
NOTE: Before servicing you will need to remove the
front panel of the heater. There are 4 tapping screws,
2 on the left side and 2 on the right, securing the front
panel to the heater (see Fig. 26).
Always allow the unit to cool for at least thirty minutes
before attempting to remove the front panel.
