nMANUAL LIGHTINGn
PROCEDURE
1.Remove lower front panel (see Figure 7 page 7).
2.Follow steps through 5 under Lighting Instructions on page12.
3.With control knob pressed in, strike match. Hold match to pilot until pilot lights.
4.Keep control knob pressed in for 30 seconds after lighting pilot. After 30 seconds, release control knob. Follow step 8 under Lighting Instuctions on page 12.
5.Replace lower front panel.
nINSPECTING BURNERn
Check pilot flame pattern and burner flame pattern often.
PILOT FLAME PATTERN
Figure 20 shows a correct pilot flame pattern. Figure 21 shows an incorrect pilot flame pattern. The incorrect pilot flame is not touching thermocouple. This will cause the
thermocouple | to | cool. When | the |
thermocouple | cools, the heater will | ||
shut down. If pilot | flame pattern is | ||
incorrect, as shown | in Figure 21. |
| |
• turn heater off (see To Turn | Off | ||
Gas to Appliance on page | 11 |
for
•see Troubleshooting. pages 14 through 16.
BURNER FLAME PATTERN |
| |||||
Figure 22 | shows a correct | burner | ||||
flame pattern. Figure 23 shows | an | |||||
incorrect | burner | flame pattern. | If | |||
pilot flame | pattern | is | incorrect, | as | ||
shown in | Figure 23. |

WARNING: If yellow |
| tipping | ||||
occurs, your heater could | produce | |||||
increased levels | of | carbon | ||||
monoxide. If burner | flame |
| pattern | |||
shows yellow tipping, follow instruc- | ||||||
tions at | bottom | of | this | page. |
Notice: Do not mistake orange flames with yellow tipping. Dirt or other fine particles enter the heater a n d b u r n c a u s i n g b r i e f patches of orange flame.

ODS/PILOT AND BURNER
•Use a vacuum cleaner, pres- surized air or a small, soft bristled brush to clean.
CLEANING BURNER
PILOT AIR INLET HOLE
We recommend that you clean the unit every 2,500 hours of operation or every three months. 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 PSl. 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 compressed 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.
1.Shut off the unit, including the pilot. Allow the unit to cool for at least thirty minutes.
2.Inspect burner and pilot for dust and dirt.
3.Blow air through the ports/slots and holes in the burner.
Also clean the pilot assembly. A yellow tip on the pilot flame indi- cates dust and dirt in the pilot assembly. There is a small pilot air inlet hole about two inches from where the pilot flame comes out of the pilot assembly (see Figure 24). With the unit off , lightly blow air through the air inlet hole. You may blow through a drinking straw if compressed air is not available.

CLEANING AND
MAINTENANCE
WARNING: Turn off heater and let cool before servicing.
CAUTION: You must keep con- trol areas, burner, 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, bedding material, pet hair, etc.
