INSPECTING BURNERS

•  turn heater off (see 

To Turn Off Gas to Ap-

pliance

, page 19).

•  see 

Troubleshooting

, page 22.

Note: The pilot flame on natural gas units will 

have a slight curve, but flame should be blue 

and have no yellow or orange color.

BURNER PRIMARY AIR HOLES

Air is drawn into the burner through the holes 

in  the  fitting  at  the  entrance  to  the  burner. 

These holes may become blocked with dust, 

lint or pet hair. Periodically inspect these holes 

for  any  blockage  and  clean  as  necessary. 

Blocked air holes will create soot.

MAIN BURNER

Periodically inspect all burner flame holes with 

the heater running. All slotted burner flame 

holes should be open with yellow flame pres-

ent. All round burner flame holes should be 

open with a small blue flame present. Some 

burner flame holes may become blocked by 

debris or rust, with no flame present. If so, 

turn off heater and let cool. Remove blockage. 

Blocked burner flame holes will create soot.

CLEANING AND MAINTENANCE

Check pilot flame pattern and burner flame 

patterns often.

PILOT FLAME PATTERN

Figure 23 shows a correct pilot flame pattern. 

Figure 24 shows an incorrect pilot flame pat-

tern. The incorrect pilot flame is not touching 

the thermocouple. This will cause the thermo-

couple to cool. When the thermocouple cools, 

the heater will shut down.
If pilot flame pattern is incorrect, as shown 

in Figure 24.

  WARNING:  Turn  off  heater 

and let cool before cleaning.

  CAUTION:  You  must  keep 

control areas, burner and circu-

lating 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 clean-

ing  due  to  excessive  lint  from 

carpeting, bedding material, pet 

hair, etc.

 WARNING: Failure to keep 

the  primary  air  opening(s)  of 

the burner(s) clean may result in 

sooting and property damage.

BURNER ORIFICE 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.
