   WARNING:   Test  all  gas piping

and  connections  for  leaks after
installing  or  servicing.   Correct   all
leaks   at   once.

    WARNING:   Never  use  an  open

flame   to   check   for  a   leak. Apply   a
mixture   of   liquid   soap and   water
to   all   joints.  Bubbles forming
show  a leak.  Correct  all   leaks  at
once.

1.   Disconnect   appliance   with   its
       appliance       main        gas     valve
     (control valve)   and   equipment
      shutoff    valve   from   gas   supply
     piping  system.  Pressures  in
       excess  of   1/2  psig  will  damage
      heater  regulator.
2.    Cap   off  open   end   of   gas  pipe

where  equipment  shutoff  valve

       was   connected.

4.   Check  all  joints  of  gas  supply

piping  system.  Apply  mixture  of
liquid  soap  and  water  to  gas
joints. Bubbles  forming  show

      a  leak.
5.   Correct  all  leaks  at  once.
6.   Reconnect heater and equipment
       shutoff  valve  to  gas supply.  Check

reconnected   fittings  for  leaks.

1.   Close equipment  shutoff  valve
       (see Figure 15).
2.   Pressurize  supply  piping  system
       by  either  using  compressed  air
      or  opening  propane/LP  supply
      tank  valve.
3.   Check  all  joints  from   gas  meter
    to equipment  shutoff  valve

4.   Correct  all  leaks  at  once.

1.  Open  equipment  shutoff  valve
      (see  Figure  15).
2.   Open propane/LP  supply  tank
      valve.
3.   Make    sure    control    knob    of
      heater  is  in  the  OFF position.
4.   Check  all  joints  from  equipment
      shutoff   valve   to   control   valve
      (see Figure 16 ).  Apply  mixture  of
        liquid   soap    and    water  to   gas
     joints. Bubbles  forming  show
      a  leak.
5.   Correct all leaks at once.
6.   Light    heater    (see   Operating
     Heater,  pages  10  and  11  for
       thermostat    model    or   page 12
    for  non-thermostat  model).
     Check   the  rest  of  the internal
      joints  for  leaks.
7.   Turn  off  heater (see  To  Turn  Off

Gas  To  Appliance,  page 11  for
thermostat  model  or  page

       12  for  non-thermostat  model).

A.    This   appliance  has  a  pilot  which
     must    be   lighted   by   hand.
     When  lighting  the  pilot,  follow
      these  instructions  exactly.
B.  BEFORE  LIGHTING  smell  all
     around   the  appliance  area  for
     gas.  Be  sure  to  smell  next  to
      the  floor  because  some  gas  is
     heavier  than  air  and  will  settle
      on the  floor .

 

Do  not  try  to  light any  appliance.

 

Do not touch any electric switch;

    do not use any phone in your
       building.

 

Immediately       call      your     gas

    supplier from  a  neighbor’s
       phone.     Follow        the        gas
       supplier’s   instructions.

 

If     you     cannot    reach     your

    gas  supplier,  call   the  fire
      department.

C.  Use  only  your  hand  to  push  in
     or  turn  the   gas   control  knob.
     Never   use   tools.  If   the   knob
    will  not  push  in  or  turn  by
      hand, don’t  try  to  repair  it, call
     a qualified service technician or
      gas supplier. Force or attempted
    repair may result in  a fire or
      explosion.
