     information  on  the  side of
       heater.
2.  Check  that  gas  supply  to
       heater  is  on.
3.  Push  in  gas  control  knob
        slightly  and  turn  clockwise  to  the
       OFF position.

NOTE:   knob  cannot  be  turned from
      “PILOT”  to  “OFF”  unless knob  is
      pushed  in  slightly. Do  not use
      force.

4.   Wait five (5) minutes  to  clear
      out   any   air. Then   smell  for
       gas,  including  near  the  floor.
        If      you      smell     gas,    STOP!
       Follow   “B”     in     the     safety
        information  on  the  side of  the
       heater.  If   you   do   not   smell
       gas,  go  to  the  next  step.
5.    Push     in    gas   control   knob
        slightly                  and                 turn
       counterclockwise    

            to

      “PILOT/IGN”  and  depress  for
        five(5) seconds
NOTE:   You may be running this
heater  for the  first  time  after hooking
up to  gas  supply. If so, 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.

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.

2.   Follow   steps   1   through  5
        under Lighting Instructions.
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.
5.     Replace   lower front   panel.

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.

            CAUTION:   Do  not  try  to
adjust  heating  levels  by  using
the  equipment  shutoff  valve.
