CONNECTING  TO  GAS SUPPLY
         
 WARNING
:  A  qualified  service
person  must  connect  heater  to  gas
supply. Follow  all  local  codes.
         CAUTION:    Never      connect heater
directly  to  the  gas supply.  This  heater
requires an    external  regulator (not
supplied). lnstall  the  external  regulator
between the  heater  and gas supply.
INSTALLATION   ITEMS  NEEDED
Before  installing  heater, make  sure you
have  the  items  listed  below.
 
piping (check  local  codes)
   sealant (resistant to natural or propane/
      LP gas)
   equipment  shutoff  valve*
   test  gauge  connection*
   sediment  trap
   see  joint
   pipe  wrench
 
flexible gas hose (check local codes).
* A  CSA  design-certified  equipment shutoff
valve   with 1/8
 NPT  tap  is  an acceptable
alternative  to  test   gauge  connection.
Purchase  the    optional  CSA  design-
certified         equipment  shutoff  valve from
your dealer. See  Accessories, page 16.
Figure  7 -Gas  Connection
The  installer  must  supply  an  external
regulator.  The  external  regulator  will re-
duce  incoming  gas  pressure. You must
reduce  incoming  gas  pressure to  be-
tween  11 to 14
 
 inches. If you do not re-
duce incoming gas pressure, heater regu-
lator damage could  occur. lnstall external
regulator with  the  vent  pointing  down  as
shown in  Figure  6.  Pointing  the  vent
down protects  it  from  freezing  rain  or
sleet.
*   Purchase  the  optional  CSA  design-certified  equipment  shutoff  valve  from
    your  dealer. See  Accessories, page  14.
** 11” W.C. pressure is the minimum  inlet  pressure  for  purpose  of  input  adjustment.
INSTALLATION
Continued
          WARNING:  Never connect heater to
private (non-utility) gas wells. This gas
is commonly known as wellhead gas.
         CAUTION:   Only use a new  black
iron  or  steel  pipe. Internally-tinned cop-
per  tubing  may  be  used  in certain
areas.  Check  your  local  codes.  Use
pipe  of 1/2
"
 diameter  or greater  to  allow
proper  gas  volume to  heater. If  pipe  is
too  small, undue loss  of  pressure  will
occur.
Installation  must   include  an   equipment
shutoff  valve, union, and plugged 1/8
"
 NPT
tap.  Locate  NPT  tap  within  reach  for  test
gauge  hook up.  NPT  tap  must  be  up-
stream  from heater (see  Figure 7).
IMPORTANT:  Install     equipment shutoff
valve  in  an  accessible  location.  The
equipment  shutoff   valve  is  for  turning  on
or  shutting  off  the  gas  to  the  appliance.
Apply pipe  joint  sealant  lightly  to  male
threads.This  will  prevent  excess      seal-
ant  from going into pipe. Excess   sealant
in  pipe  could  result  in clogged heater
valves.
         CAUTION:   Use pipe joint sealant
that  is  resistant  to  liquid petroleum(LP)
gas.
We  recommend  that  you install  a sedi-
ment  trap  in  supply  line  as  shown in
Figure 7. Locate  sediment  trap  where  it  is
within  reach  for  cleaning. Install  in  piping
system  between  fuel supply  and  heater.
Locate  sediment trap  where  trapped
matter is not  likely to  freeze.  A  sediment
trap  traps  moisture  and  contaminants.
This  keeps  them  from  going  into  heater
controls. If  sediment  trap  is  not      in-
stalled  or  is  installed  incorrectly,  heater
may  not  run  properly.
               CAUTION:   Avoid  damage to
regulator. Hold  gas  regulator  with wrench
when  connecting  into  gas piping  and/or
fittings.
NG  MODELS:
5” to 10.5” W.C.
