tern. Incorrect pilot flame is not touching ther

-

mocouple. This will cause the thermocouple 
to  cool.  When  thermocouple  cools,  heater 
will shut down.
If  pilot  flame  pattern  is  incorrect,  as  shown 

in Figure 30

•  turn  heater  off  (see 

To  Turn  Off  Gas  to 

Appliance

, page 20

•  see 

Troubleshooting

, page 24

Note: 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 burner through holes in fit

-

ting at entrance to burner. These holes may 

become blocked with dust or lint. 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 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

  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.

ODS/pILOT AND BURNER

Use a vacuum cleaner or small, soft bristled 

brush to clean.

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 and lint. 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 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 
directions on can. If you don’t follow directions 
on can, you could damage pilot assembly.
