FRONT BURNER FLAME PATTERN

Figure  26  shows  correct  front  burner  flame 
pattern.  Figure  27  shows  incorrect  front 
burner  flame  pattern.  The  incorrect  burner 
flame pattern shows yellow tipping at top of 
blue flame.

 WARNING: If yellow tipping 

occurs, your heater could pro

-

duce increased levels of carbon 

monoxide. If front burner flame 

pattern  shows  yellow  tipping, 

follow instructions at bottom of 

this page. Yellow flame on rear 

burner is normal.

NOTICE: Do not mistake orange 

flames with yellow tipping. Dirt 

or other fine particles are burned 

by heater, causing brief patches 

of orange flame.

CLEANING

INSPECTING bURNERS

Continued

If front burner flame pattern is incorrect, as 
shown in Figure 27
•  turn heater off (see 

To Turn Off Gas to Ap-

pliance

, page 19)

•  see 

Troubleshooting

, page 22

  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  opening(s)  of 

the burner(s) clean may result in 

sooting and property damage.

BURNER INjECTOR HOLDER AND 

PILOT AIR INLET HOLE

The primary air inlet holes allow the proper 
amount of air to mix with the gas. This pro

-

vides  a  clean  burning  flame.  Keep  these 
holes  clear  of  dust,  dirt,  lint  and  pet  hair. 

Clean  these  air  inlet  holes  prior  to  each 

heating season. Blocked air holes 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. 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 dam

age the pilot assembly.
