  and  depress  for

        five(5) seconds

NOTE:   The  first  time  that  the
heater   is  operated  after  connecting
the   gas  supply ,  the   control   knob
should  be  depressed for  about  thirty
(30) seconds.  This will   allow  air  to
bleed   from  the  gas  system.

6.    With  control  knob  pressed  in,
       push  down  and   release   the
     ignitor button. This  will  light
       pilot. If  needed,   keep    pressing
     ignitor button until pilot  lights.

NOTE:  If  pilot  does  not  stay  lit,refer
to  Troubleshooting,  pages 14 through
16.   Also  contact  a  qualified  service
person  or  gas   supplier   for  repairs.
Until   repairs are   made,   light   pilot
with   match. To light  pilot  with match,
see Manual   Lighting   Procedure.

7.   Keep  control  knob  pressed  in
     for  thirty  (30)  seconds  after
       lighting       pilot.         After       30
       seconds,  release  control  knob.

 

If   control   knob  does   not   pop

     up  when  released,  contact  a
      qualified     service    person    or
       gas  supplier  for  repairs.

NOTE:   If  pilot  goes  out,  repeat
steps 3 through 7. Wait one (1)
minute  before  lighting  pilot  again

8.   Turn             control            knob
       counterclockwise       

          to

      desired    heating    Level.   The
      main  burner  should  light.  Set
      control  knob  to  any  heat  level
       between  HI  and  LO.

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.  The
thermostat     adjusts     the    amount
of    gas    flow     to     the       burner.

This  increases  or  decreases   the
burner  flame height.  At  times  the  room
may exceed  the  set temperature.  If  so,
the  burner  will  shut  off.  The  burner
will  cycle  back  on  when room  tem-
perature  drops   below  the set
temperature. The    control knob  can  be
set  to  any  heat  level between  HI and
LO. Selecting  the HI  setting  will  cause
the  burner  to remain  fully  on  without
modulating  down  in  most cases.

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.
