CLEANING ODS/PILOT AND
BURNER
Use    a      vacuum    cleaner,
pressurized  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   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, 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 26).
With  the  unit  off, lightly blow air
through  the  air inlet hole. You may
blow  through  a drinking  straw  if  com-

PROCEDURE
1.   Remove  lower  front  panel (see
      Figure 7 page 7).
2.  Follow    steps   1   through   5
    under  Lighting  Instructions on
      page  12.
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
     Instructions 
on page 12.
5.  Replace  lower  front  panel.
INSPECTING  BURNER
Check   pilot   flame  pattern  and
burner  flame  pattern  often.
PILOT  FLAME  PATTERN
Figure  22  shows  a  correct  pilot
flame  pattern.  Figure  23 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 23.
 turn  heater off  (see  To  Turn       Off
Gas  To  Appliance.  page  11  for
n o n - t h e r m o s t a t   m o d e l s   o r

  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.  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.

THERMOSTAT
n
CONTROL  OPERATION
The  thermostatic  control  used  on
these  Models  differs  from  standard
thermostats. Standard  thermostats
simply  turn on  and  off  the  burner.
The  thermostat  used  on  this  heater
senses  the  room  temperature. At
times the  room  may  exceed  the  set
temperature.  If  so, the  burner  will  shut
off.  The  burner  will  cycle  back  on
when  room   temperature  drops  below
the  set  temperature. The     control
knob  can  be  set  to any  heat
level  between  HI and  LO.
NOTE
: The  thermostat  sensing  bulb
measures  the  temperature  of  air  near
the  heater  cabinet. This  may  not  al-
ways  agree  with  room  temperature
(depending  on  housing  construction,
installation  location, room  size, open
air  temperatures, etc.)Frequent  use of
your  heater  will  let   you determine
your  own  comfort  levels.
