Figure  23  shows a  correct   burner
flame  pattern.  Figure 24  shows  an
incorrect  burner   flame  pattern.  If
pilot flame   pattern   is   incorrect,   as
shown  in  Figure 24.

 

  turn  heater  off  (see  To  Turn  Off

Gas To Appliance. page 12 for non-
thermostat  models  or  page

        11  for  thermostat  models)

     see  Troubleshooting. (pages  14

        through 16)

 

Use    a      vacuum    cleaner,

pressurized  air  or a  small,  soft

        bristled  brush  to  clean.

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   com-
pressed  air  no  greater  than   30  PSl.
Your  local  computer  store,  hard-
ware 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 direc-
tions 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,  pilot  for  dust
         and  dirt.
3.       Blow  air  through  the  ports/slots
         and  holes  in  the  burner.
Also, clean  the  pilot  assembly.   A yel-
low  tip  on  the  pilot  flame   indicates
dust  and  dirt  in  the  pilot assembly.
There  is  a  small  pilot  air inlet  hole
about  two  inches  from where  the  pi-
lot  flame  comes  out  of the  pilot  as-
sembly  (see  Figure 25). 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.

     Use     a      vacuum     cleaner    or

        pressurized  air  to  clean.
Exterior

     Use  a  soft  cloth  dampened  with

        a  mild  soap  and  water  mixture.
        Wipe  the  cabinet  to  remove dust.

Check   pilot   flame  pattern  and
burner  flame  pattern  often.

Figure  21  shows  a  correct  pilot
flame  pattern.  Figure  22 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 22.

 

turn  heater off  (see  To  Turn

Off  Gas  To  Appliance.  page  12
for non-thermostat models or

       page 11  for thermostat models.)

 

 see  Troubleshooting.  pages  14

        through 16.

WARNING:   Turn off heater

and  let  cool  before  servicing.

  CAUTION:  You  must keep  control

areas,  burner,  and  circulating  air
passageways  of heater  clean.  In-
spect 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:   If   yellow   tipping

Notice:   Do not mistake orange
flames  with  yellow  tipping.  Dirt
or other fine particles enter the
heater and burn causing brief
patches  of  orange  flame.
