MAINTENANCE:

Always­keep­the­heater­area­clear­and­free­from­
combustible­materials,­gasoline­and­other­flammable­
vapors­and­liquids.­­
Keep­the­vent­areas­(slots­in­the­bottom­and­top­of­the­
heater)­clear­at­all­times.
Visually­inspect­the­pilot­flame­and­burner­periodically­
during­use.­­The­pilot­flame­should­be­blue­in­color­(not­
yellow)­and­will­extend­to­the­thermocouple.­The­flame­will­
surround­the­thermocouple­just­below­the­tip,­see­Figure­2.
A­slight­yellow­flame­may­occur­where­the­pilot­flame­
