FPB Pro Spur Burners Fire Pits with AWS System
6. Fire Feature Cycles (Turns On and Off) Every Few Minutes
• Gas Volume Insufficient
– See symptom 5 page 21 for “Gas Volume Insufficient” for detailed explanation.
• Oxygen Starvation (Pilot Burner)
– See symptom 5 page 21 for “Oxygen Starvation” for detailed explanation.
• Defective Thermopile
– See symptom 4 page 21 for “Defective Thermopile” for detailed explanation
• Defective Controller
– See symptom 5 page 21 for “Defective Controller” for detailed explanation
7. Main Burner Flame Lazy/Small or Flame NOT Spread Out Over Entire Burner
• Gas Volume Insufficient
– See symptom 5, page 21 for “Gas Volume Insufficient” for detailed explanation
• Debris On Inlet Screen; Valve Box
– See symptom 3, symptom 4, page 21 for “Debris on inlet screen for detailed
explanation
• Debris On Outlet Screen; Valve Box
– See symptom 4, page 21 for “Debris on Outlet Screen for detailed
explanation.
• Obstruction In Plumbing Between Gas Valve Outlet and Main Burner
– If your plumbing was sized correctly to
deliver the proper amount of gas and the screens in the valve box are clean, inspect the plumbing between the valve
and the burner for obstructions. Also, inspect inside the burner inlet to ensure no obstructions in there as well.
8. Main Burner Flame “Flares Up” Every Few Minutes
• Fire glass/Media Layer too Thick
– Fire glass/media comes in different sizes. Use only ½” - ¾” diameter. If you put
a thick layer of fire glass/media on top the burner, over 1” in depth; there is a good chance some of the gas will get
“trapped” within the media while the feature is ON. When this happens, the trapped gas in the fire feature ignites and
you see the “
Flare Up
” effect. Remove some of the fire glass/media from the burner to see if this fixes the problem.
• Gas Leak
– Natural Gas is lighter than air therefore when released into the atmosphere it rises. If you have a Natural
Gas fire feature and there is a gas leak the Natural Gas will rise to the top of the feature. Once it encounters the flame
a flare up will occur. Propane is heavier than air so if there is a gas leak when using propane the gas will fall into the
bottom of the feature. That is why it is REQUIRED drainage/ventilation be installed at the bottom of the feature when
using Propane. You do NOT want Propane accumulating inside the fire feature.
9. Turn the Feature OFF…but a Small Flame Continues to Burn in the Pilot Burner
• Leak in the Pilot Burner Gas Valve
– When debris enters the gas valve by way of either the Inlet or outlet there is
a chance some of that debris will enter the Pilot Burner Gas Valve and contaminate the seal inside the valve. If this
occurs, the possibility exists the valve will not seal properly when turned
OFF
thereby allowing a small amount of gas
to flow even after being turned OFF. Often this will result in a small flame that continues to burn in the Pilot Burner
after the feature has been turned OFF.
• Leak in the Main Burner Gas Valve
- when debris enters the gas valve by way of either the Inlet or Outlet there is
a chance some of that debris will enter the Main Burner Gas Valve and contaminate the seal inside the valve. If this
occurs the possibility exists the valve will not seal properly when turned off thereby allowing a small amount of gas
to flow even after turned off. Often this will result in a small flame that continues to burn on the Main Burner after the
feature has been turned OFF.
