BURNER FLAME PATTERN
Figure 24 shows correct burner flame pattern.
NOTICE: Do not mistake orange flames with yellow tipping. Dirt or other fine particles are burned by heater, causing brief patches of orange flame.
If burner flame pattern is incorrect, as shown in Figure 25
•turn heater off (see To Turn Off Gas to Appli- ance, page 17)
•see Troubleshooting, page 22
The flames from the burner travel horizontally through the log set and emerge at the middle and rear of the set against the back logs.
The flames are blue off the burner and as they progress through the log set, change to a light yellow color, yellow decorative flames are visible as the flames exit the log set.
The base of the log set and the underside of the top logs glow red. Natural gas models will burn with more blue flame, while propane gas model will burn with bright yellow flame.

CLEANING AND
MAINTENANCE
WARNING: Turn off heater and let cool before cleaning.
CAUTION: You must keep control areas, burners and circulating air passageways of heater clean. Inspect these areas of heater before each use. Have heater inspected yearly by a qualified service person. Heater may need more frequent cleaning due to excessive lint from carpeting, pet hair, bedding material, etc.
WARNING: Failure to keep the primary air openings of the burner clean may result in soot- ing and property damage.
BURNER INJECTOR HOLDER AND PILOT AIR INLET HOLE
The primary air inlet openings allow the proper amount of air to mix with the gas. This provides a clean burning flame. Keep these holes clear of dust, dirt, lint and pet hair. Clean these air inlet openings prior to each heating season. Blocked air openings will create soot. We recommend that you clean the unit every three months during operation and have heater inspected yearly by a qualified service person.
We also recommend that you keep the burner tube and pilot assembly clean and free of dust and dirt. To clean these parts we recommend using compressed air no greater than 30 PSI. Your local computer store, hardware store or home center may carry compressed air in a can. You can use a vacuum cleaner in the blow position. If using com- pressed air in a can, please follow the directions on the can. If you don't follow directions on the can, you could damage the pilot assembly.
