 WARNING:    Test  all  gas

piping   and  connections  for  leaks
after  installing  or  servicing.   Cor-
rect   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.
3.     Pressurize             supply           piping

compressed   air   or    opening

       propane/LP  supply  tank  valve.
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 14).
2.   Pressurize  supply  piping  system
       by  either  using  compressed  air
      or  opening  propane/LP  supply
      tank  valve.
3.   Check  all  joints  from  propane/LP

supply  tank  to   equipment     shutoff
valve  (see  Figure 14).  Apply
mixture  of  liquid  soap and water
to  gas  joints. Bubbles  forming
show  a leak.

4.   Correct  all  leaks  at  once.

1.  Open  equipment  shutoff  valve
      (see  Figure  14).
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 15 ).  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 10,11and  12) Check
    the  rest  of  the  internal  joints  for
       leaks.
7.  Turn  off  heater (see  To  Turn  Off
     Gas  to  Appliance,  pages 11 and

12).

8.    Replace  lower  front  panel.

A   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.
D.  Do not use this appliance if any

      any  part  of  the  control  system
     and any gas control which has
      been  under  water.
