Burner: The burner is made from heavy wall 304 stainless steel, but extreme heat and a corrosive
environment can cause surface corrosion to occur. This can be removed with a brass wire brush. Inspect
the burner at least annually for cracks, insect nests, excessive corrosion or any other damage. If the
burner is damaged, it must be replaced with a burner specified by the manufacturer before the appliance
is put into operation.
CAUTION!
Beware of Spiders.
Spiders and insects are attracted to the smell of propane and natural gas. The burner is equipped with an
insect screen on the air shutter, which reduces the likelihood of insects building nests inside the burner
but does not entirely eliminate the problem. A nest or web can cause the burner to burn with a soft
yellow or orange flame or cause a fire (flashback) at the air shutter underneath the control panel. Other
warning signs that may indicate a problem are:
• Strong or unusual odor coming from the appliance.
• Continued difficulty or delayed ignition.
• Flame appears either very short or very long.
• Flame only burns part way across the burner.
• Excessive soot building up on the glass embers.
To clean the inside of the burner, it must be removed from the appliance: Remove the front glass shield
and the glass embers and examine the burner. If dirty, clean with a wire brush. Remove the screws that
attach the glass ember tray and the wind shield. Cleaning: Use a flexible venturi tube brush to clean the
inside of the burner. Shake any loose debris from the burner through the gas inlet. Check the burner ports
and valve orifices for blockages. Burner ports can close over time due to debris and corrosion, use an
opened paperclip or a drill bit to clean them The ports are easier to clean if the burner is removed from
the appliance, but it can also be done with the burner installed.
Lift the glass tray from the fireplace, pushing from the top, disengage the thermocouple and igniter from
the glass tray.
Remove the flex hose and the orifice from the burner and completely remove the glass tray from the
fireplace.
