IMPORTANT  INFORMATION  –  READ  CAREFULLY

 

NOTE:   The   equipment   shall   be   installed   in   accordance   with   those   installation   regulations   required   in   the   area   where  the  installation  is  to  be  made.  These  regulations  shall  be  carefully  followed  in  all  cases.  Authorities  having  

  jurisdiction  shall  be  consulted  before  the  installations  are  made.  

All  wiring  on  water  heaters  must  be  in  accordance  with  the  National  Electrical  Code  (latest  edition)  and/or  local   regulations  in  the  US,  and  in  accordance  with  the  Canadian  Electrical  Code  (latest  edition)  and/or  local  regulations  

 

in  Canada.  

Improper  installation,  adjustment,  alteration,  service  or  maintenance  can  cause  property  damage,  personal  injury,   or   loss   of   life.   Read   and   understand   the   entire   manual   before   attempting   installation,   start-­‐up,   operation,   or   service.  Installation  and  service  must  be  performed  only  by  an  experienced,  skilled  installer  or  service  agency.  

 

This  water  heater  contains  very  hot  water  under  high  pressure.  Do  not  unscrew  any  pipe  fittings  or  attempt  to   disconnect   any   components   of   this   water   heater   without   positively   assuring   that   the   water   is   cool   and   has   no   pressure.  Always  wear  protective  clothing  and  equipment  when  installing,  starting  up  or  servicing  this  water  heater   to  prevent  scalding  injuries.  Do  not  rely  on  the  pressure  and  temperature  gauges  to  determine  the  temperature   and  pressure  of  the  water  heater.  This  water  heater  contains  components  that  become  very  hot  when  the  boiler  is  

  operating.  Do  not  touch  any  components  unless  they  are  cool.  

Failure   to   follow   all   instructions   in   the   proper   order   can   cause   personal   injury   or   death.   Read   all   instructions,   including   all   those   contained   in   component   manufacturers’   manuals   before   installing,   starting   up,   operating,  

 

maintaining,  or  servicing  the  water  heater.  

To  reduce  the  risk  of  excessive  pressures  and  temperatures  in  this  water  heater,  install  temperature  and  pressure   protective  equipment  required  by  local  codes  but  no  less  than  a  combination  temperature  relief  valve  certified  by   a  nationally  recognized  testing  laboratory  that  maintains  periodic  inspection  of  production  of  listed  equipment  or   materials,   as   meeting   the   requirements   for   Relief   Valves   and   Automatic   Shutoff   Devices   for   Hot   Water   Supply  

Systems,  ANSI  Z21.22-­‐latest  edition.  This  valve  must  be  marked  with  a  maximum  set  pressure  not  to  exceed  the   marked   working   pressure   of   the   water   heater.   Install   the   valve   into   an   opening   provide   and   marked   for   this   purpose   in   the   water   heater,   and   orient   it   or   provide   tubing   so   that   any   discharge   from   the   valve   will   exit   only   within  6  inches  above,  or  at  any  distance  below,  the  structural  floor,  and  cannot  contact  any  live  electrical  part.  

The  discharge  opening  must  not  be  blocked  or  reduced  in  size  under  any  circumstances.  

Improper  water  quality  will  reduce  the  life  of  the  water  heater.  Hard  water,  sediment,  high  or  low  PH  and  high   levels   of   chlorides   in   the   domestic   water   should   be   avoided.   Be   sure   that   PH   levels   fall   between   6   and   8   and   dissolved  chlorides  are  less  than  100  ppm.  A  filter  must  be  used  where  sediment  is  greater  than  5  microns  in  size  in   the   water   supplied   to   the   unit.   A   water   softening   system   is   recommended   for   areas   with   hard   water.   In   cases   where  water  quality  is  unknown,  a  qualified  water  treatment  expert  should  be  consulted.    

NOTICE:  Damage  to  tanks  caused  by  improper  water  quality  is  not  covered  under  the  warranty.  

 

DO  NOT  store  or  use  gasoline  or  other  flammable  vapors  or  liquids  in  the  vicinity  of  this  or  any  other  appliance.    If   you  smell  gas  vapors,  DO  NOT  try  to  operate  any  appliance  -­‐  DO  NOT  touch  any  electrical  switch  or  use  any  phone   in   the   building.   Immediately,   call   the   gas   supplier   from   a   remotely   located   phone.   Follow   the   gas   supplier’s   instructions  or  if  the  supplier  is  unavailable,  contact  the  fire  department.  Do  not  operate  any  appliance  until  the   leakage  is  corrected.  

 

This   water   heater   is   supplied   with   an   adjustable   thermostat   to   control   the   water   temperature.   Hot   water   temperatures   required   for   automatic   dishwashers   and   laundry   use   can   cause   scald   burns   resulting   in   serious   personal  injury  and/or  death.  The  temperature  at  which  injury  occurs  varies  with  the  person’s  age  and  the  time  of   exposure.  The  slower  response  time  of  disabled  persons  increases  the  hazard  to  them.  NEVER  allow  small  children   to  use  a  hot  water  tap  or  to  draw  their  own  bath  water.  NEVER  leave  a  child  or  disabled  person  unattended  in  a   bathtub  or  a  shower.

Pre-­‐installation  Considerations  

 

 

Inspect  shipment  carefully  for  signs  of  damage.  All  equipment  is  carefully  inspected  and  packed.  

Heat-­‐Flo’s   responsibility   ceases   upon   delivery   of   the   water   heater   to   the   carrier   in   good   condition.  Any  claims  for  damage  or  shortage  must  be  filed  immediately  against  the  carrier  by   the  consignee.  No  claims  for  variances  or  shortages  will  be  allowed  by  the  Manufacturer,  unless   they  are  presented  within  sixty  days  after  receipt  of  the  equipment.  

Installation   must   conform   to   the   requirements   of   the   authority   having   jurisdiction.   In   the   absence  of  such  requirements,  installation  must  conform  to  the  National  Plumbing  Code  and   the  National  Electrical  Code  ANSI/NFPA  No.  70  (current  edition).  

IMPORTANT  CONSIDERATIONS  BEFORE  INSTALLATION  

1. Tank  sizing:  

Choose  the  water  heater  model  based  on  the  expected  water  usage  for  the  given  site.    

Factors  that  increase  water  demand  dramatically  include  high  flow  shower  heads,  hot   tubs,   and   the   use   of   more   than   one   shower   at   a   time.   Increase   the   tank   size   if   these   factors  are  present.  Consult  ASHRAE  sizing  guides  and  other  references.

LOCATING  THE  WATER  HEATER  

The   water   heater   should   be   located   in   an   area   where   water   leakage   from   the   tank   or   connections  will  not  result  in  damage  to  areas  adjacent  to  the  water  heater  or  to  lower  floors  of   the  structure.  When  such  a  location  cannot  be  avoided,  a  suitable  drain  pan  must  be  installed   under  the  water  heater,  and  the  drain  pan  must  be  connected  to  a  drain.  The  drain  pan  depth   must  be  suitable  for  draining  and  collecting  water.   The  piping  to  drain  must  be  at  least  3/4”   diameter  and  be  pitched  for  proper  drainage.  

The   water   heater   should   be   installed   as   close   to   the   boiler   as   is   practical   for   easy   access   for   service.  The  unit  is  designed  for  installation  on  combustible  flooring  and  in  alcoves,  closets,  etc.  

The  minimum  clearances  from  combustible  surfaces  are:

ADDITIONAL  RECOMMENDED  COMPONENTS  

1. Shut-­‐Off   Valves:   Allows   the   isolation   of   the   water   heater   from   the   boiler   system   during  service.  

2. Unions:  Allows  for  easy  locating  or  removal.  

3. Vacuum  Breaker:  Protects  the  water  heater  from  collapse  if  a  hot  tank  is  valved  off  to   service  other  components  in  the  system.  

4. Thermal   expansion   tank.   If   the   water   heater   is   installed   in   a   closed   water   supply   system,  such  as  a  system  having  a  back  flow  preventer,  a  check  valve,  or  a  pressure   reducing  valve  in  the  cold  water  supply  line,  the  installation  of  a  thermal  expansion  

  tank  is  required.  

 

For  California  installation  this  water  heater  must  be  braced,  anchored,  or  strapped  to   avoid   falling   or   moving   during   an   earthquake.   See   instructions   for   correct   installation   procedures.  Instructions  may  be  obtained  from  California  Office  of  the  State  Architect.  

 

Water  Quality  

Improper  water  quality  will  reduce  the  expected  life  of  the  water  heater.  Hard  water,  sediment,   high  or  low  Ph,  and  high  levels  of  chlorides  in  the  domestic  water  should  be  avoided.  Sediment   and  hard  water  will  eventually  coat  the  heating  coil  inside  the  water  heater  and  reduce  the  rate   of  hot  water  production  and  may  eventually  cause  a  failure.  High  or  low  Ph  and/or  high  chloride   concentrations   will   cause   corrosion   and   eventually   failure.   A   filter   is   strongly   recommended   where  sediment  is  present  in  the  water.  A  water  softening  system  is  recommended  for  areas   with  hard  water.  In  an  area  where  the  water  quality  is  not  known,  a  water  quality  test  should   be  performed.  

WARNING:  

 

 

Do  not  operate  the  Heat-­‐Flo  water  heaters  in  areas  where  the  Ph  is  above  8.0  or  below  6.0,   and/or   with   chloride   concentrations   greater   than   100   parts   per   million   (ppm).   Heat-­‐Flo’s   standard  warranty  does  not  cover  problems  caused  by  improper  water  Ph  or  excessive  levels  of   chlorides.  

 

Damage  to  tanks  caused  by  improper  water  quality  is  not  covered  under  the  warranty.  

PIPING  

DOMESTIC  WATER  PIPING  (See  Figure  1,  Pg.  3)  

1. Drain  the  domestic  water  system.    

• Shut  off  the  cold  water  supply  at  the  main  shutoff  valve.  

• Open  one  or  more  faucets  to  relieve  the  pressure.  

• Open  the  system  drain,  leaving  the  faucets  open.  

Heat-­‐Flo,  Inc.  |  Hot  Water  Storage/  Booster  Tanks     Page  |  5  

2. Position  the  water  heater  in  its  final  location  

3. Connect  the  cold  water  supply  piping.  

• Install  piping  onto  cold  inlet  connection.  

• Connect  to  cold  water  supply  connection  using  a  union,  a  heat  trap,  a  shut-­‐off  valve,  a   vacuum  breaker,  an  expansion    tank  (where  required),  and  a  filter  (recommended  to  

  prevent  sediment  buildup).  

 

If   installing   on   a   city   supply,   a   properly   sized   thermal   expansion   tank   is   required   and   should  be  installed  in  accordance  with  the  product  installation  manual.  

If   a   water   heater   is   installed   in   a   closed   water   supply   system,   such   as   one   having   a   backflow  preventer  in  the  cold  water  supply,  a  check  valve  in  the  cold  water  supply,  or  a   pressure   reducing   valve   in   the   cold   water   supply   means   shall   be   provided   to   control   thermal  expansion.  

 

The  appliance,  when  installed,  must  be  grounded  in  accordance  with  the  local  codes,  or   in  the  absence  of  local  codes,  with  the  National  Electrical  Code,  ANSI/NFPA  70.  

 

If  this  product  is  connected  to  a  cold  water  supply  line  that  has  a  check  valve,  a  backflow   preventer,   a   pressure   reducing   valve,   or   a   check   valve   in   the   water   meter,   it   is   a   requirement  that  a  properly  sized  thermal  expansion  tank  be  installed  in  the  cold  water   inlet  line.    There  will  be  no  warranty  on  applications  where  there  is  no  pressure  control.  

4. Connect  the  domestic  hot  water  piping.  

• Install  piping  onto  hot  water  supply  connection  using  a  union,  a  heat  trap,  and  a  shut   off  valve.      

• Pipe  the  relief  valve  discharge  so  that  the  discharge  from  the  valve  will  exit  only  within  

6   inches   above,   or   at   any   distance   below,   the   structural   floor   and   so   that   it   cannot   contact   any   live   electrical   part.     The   discharge   opening   must   not   be   blocked   or   reduced  in  size  under  any  circumstances.    

 

Install   a   discharge   line   so   that   water   discharged   from   the   temperature   and   pressure   relief   valve   will   exit   within   six   (6)   inches   above,   or   any   distance   below,   the   structural   floor  and  cannot  contact  any  live  electrical  part.  The  discharge  line  is  to  be  installed  to   allow  for  complete  drainage  of  both  the  temperature  and  pressure  relief  valve  and  the  

DO   NOT   thread,   plug,   or   cap   the   discharge   line.   It   is   recommended   that   a   minimum   clearance  of  four  (4)  inches  be  provided  on  the  side  of  the  water  heater  for  servicing  and   maintenance  of  the  combination  temperature  and  pressure  relief  valve.  

Do  not  place  a  valve  between  the  combination  temperature  and  pressure  relief  valve  

and  the  tank!  

Heat-­‐Flo,  Inc.  |  Hot  Water  Storage/  Booster  Tanks     Page  |  6  

5. Fill  the  water  heater.  

• Open   all   faucets   to   allow   air   to   purge   from   the   tank   and   piping.   Remove   screens   on   faucets.  

• Open  domestic  hot  water  shut-­‐off  valve.  

• Open  cold  water  inlet  shut-­‐off  valve.    

• Purge  all  of  the  air  from  the  domestic  water  system.  Allow  water  to  run  so  the  tank  is   completely  purged  of  any  debris.  Run  the  water  long  enough  to  change  at  least  five   tank  volume  changes.    

• Close  all  faucets.  Reinstall  all  of  the  screens  in  the  faucets.  

• Check  the  system  for  leaks.  Repair  as  required.  

OPERATION  

STARTUP  

After  the  water  heater  has  been  plumbed  and  wired  and  the  boiler  water  piping  is  purged  of   air,  the  water  heater  is  ready  to  be  started.    

1. The  tank  thermostat  is  factory  pre-­‐set  to  125  degrees  F  and  will  call  for  heat  if  the  water  in   the  tank  is  lower  than  that  (125  deg.  F).    

2. On  a  call  for  heat,  the  tank  thermostat  contacts  close  to  start  the  circulator.    

3. After   the   tank   has   reached   the   temperature   setting,   the   tank   thermostat   opens   and   de-­‐ energizes  the  circulator.    

                                                     -­‐  

SCALDING!  

This  water  heater  can  deliver  scalding  temperature  water  at  any  faucet  in  the  system.    

Be  careful  when  using  hot  water  to  avoid  scalding  injury.    By  setting  the  thermostat  on   this  water  heater  to  obtain  an  increased  water  temperature,  you  create  the  potential   for  scald  injury.    To  protect  against  injury,  you  should  install  an  ASSE  approved  mixing   valve   (a   device   to   limit   the   temperature   of   water   to   protect   against   scald   injury   via   mixing  hot  and  cold  water  supply)  in  the  water  system.    This  valve  will  reduce  point  of   discharge   temperature   in   branch   supply   lines.     Such   valves   are   available   from   a   local   plumbing  supplier.    Please  consult  with  a  plumbing  professional.      

 

SCALD  RELATIONSHIPS  

The  tank  thermostat  controls  the  maximum  water  temperature  in  the  water  heater.  If  it  is  set   too   high,   the   resulting   hot   water   can   cause   painful   scalding   with   possible   serious   and   permanent   injury.   The   temperature   at   which   this   occurs   varies   with   a   person’s   age,   and   the   length   of   time   in   contact   with   the   hot   water.   The   slower   response   time   of   infants,   older,   or   handicapped  people  increase  the  hazard  for  them.  

 

Heat-­‐Flo,  Inc.  |  Hot  Water  Storage/  Booster  Tanks     Page  |  7  

WATER  TEMPERATURE  ADJUSTMENT  

It  is  recommended  that  the  thermostat  be  set  for  the  lowest  possible  temperature  that  satisfies   your  needs.  This  will  also  provide  you  with  the  lowest  energy  consumption  and  cost.  

Check   the   water   temperature   at   a   hot   water   faucet   soon   after   the   tank   thermostat   has   satisfied,  and  the  circulator  and  the  boiler  have  turned  off.  Adjust  as  needed.  

Lowering  the  thermostat  setting  will  not  have  an  immediate  effect  on  the  water  temperature   because  the  stored  water  will  have  to  be  used  and  the  thermostat  must  go  through  the  cycle  of   heating   cold   water   and   satisfying   at   the   new,   lower   temperature.   Additional   temperature   checks  should  follow  the  completion  of  a  heating  cycle.  Further  adjustments  may  be  required  

  after  you  have  used  the  water  heater.  

 

The   table   below   details   the   approximate   relationship   of   water   temperature   and   time   with  regard  to  scald  injury  and  may  be  used  as  

  a   guide   in   determining   the   safest   water   temperature  for  your  applications.  

 

 

The   scald   label   shown   to   the   right   can   be   found   on   all   Heat-­‐Flo   Indirect   Water   Heaters   and  Storage  tanks.    Take  note  and  use  caution   when  adjusting  the  temperature  settings  with   your  water  system.    Be  sure  to  always  feel  the   water  before  bathing  or  showering,  especially   when  drawing  a  bath  for  an  infant  or  elder.

It  is  the  responsibility  of  the  installing  contractor  to  see  that  all  controls  are  correctly   installed  and  are  operating  properly  when  the  installation  is  complete.      

DO  NOT  operate  the  water  heater  with  jumpered  or  absent  controls  or  safety  devices.      

DO  NOT  tamper  with  or  alter  the  water  heater  and/  or  controls.  

DO   NOT   operate   the   water   heater   if   any   external   part   has   been   under   water.    

Immediately  call  a  qualified  service  technician  to  inspect  the  appliance  and  to  replace   any  part  of  the  control  system  that  is  or  had  been  under  water.      

DO   NOT   install   this   water   heater   on   carpeting.     This   water   heater   is   suitable   for   installation  on  combustible  flooring.  

DO  NOT  operate  this  water  heater  without  first  being  certain  it  is  filled  with  water.  

MAINTENANCE  

The  water  heater  is  intended  to  provide  many  years  of  reliable  service.  Components,  such  as   thermostats  and  relief  valves,  may  be  subject  to  failures  that  require  service .

 Depending  on  the   quality  of  the  water  supply,  sediment  and/or  scale  may  coat  the  heating  coil  in  the  tank  and   reduce   hot   water   recovery   rate.   Failure   to   use   the   correct   procedures   or   parts   can   result   in   unsafe  operation.  

The   owner   should   arrange   to   have   the   following   inspections   and   simple   maintenance   procedures  done  at  the  suggested  frequencies.  

1. Domestic  Water  Piping  (Annual)  

• Check   all   piping   for   signs   of   leakage   at   the   joints,   unions   and   shut-­‐off   valves.   Repair   as   required.  

2. Temperature  and  Pressure  Relief  Valve  (Annual)  

• The   temperature   and   pressure   relief   valve   should   be   checked   to   ensure   that   it   is   in   operating  condition.  To  check  the  relief  valve,  lift  the  lever  at  the  end  of  the  valve  several   times.  The  valve  should  seat  properly  and  operate  freely.  If  water  does  not  flow,  remove   and  inspect  for  obstructions  or  corrosion.  Replace  with  a  new  valve  of  the  recommended   capacity  as  necessary.  Do  not  attempt  to  repair  the  valve,  as  this  could  result  in  improper   operation  and  a  tank  explosion.  In  areas  with  poor  water  conditions,  it  may  be  necessary   to  inspect  the  temperature  and  pressure  relief  valve  more  often  than  once  a  year.  

 

Before  manually  operating  the  valve,  make  sure  that  a  drain  line  has  been  attached  to  the  valve   to  direct  the  discharge  to  an  open  drain.  Failure  to  take  this  precaution  could  mean  contact  with   extremely  hot  water  discharging  from  the  valve  during  this  checking  operation.  

If   the   temperature   and   pressure   relief   valve   on   the   heater   discharges   periodically   or   continuously,  it  may  be  due  to  thermal  expansion  of  water  in  a  closed  water  supply  system,  or  it   may  be  due  to  a  faulty  relief  valve.  Thermal  expansion  is  the  normal  response  of  water  when  it  is   heated.  In  a  closed  system,  thermal  expansion  will  cause  the  system  pressure  to  build  until  the   relief  valve  actuation  pressure  is  equaled.  Then  the  relief  valve  will  open,  allowing  some  water   to   escape,   slightly   lowering   the   pressure.   Contact   your   water   supplier   or   local   plumbing   inspector  on  how  to  control  this  situation.

ABOVE  ALL,  DO  NOT  PLUG  THE  TEMPERATURE  AND  PRESSURE  RELIEF  VALVE.  THIS  IS  NOT  A  

SOLUTION  AND  CAN  CREATE  A  HAZARDOUS  SITUATION.  

3. Sediment  (Annual  except  where  harsh  water  quality  may  require  more  frequent  service)  

• Depending   on   water   conditions,   a   varying   amount   of   sediment   may   collect   in   the   tank.  

Levels   requiring   service   are   indicated   by   a   small   temperature   difference   between   the   boiler   supply   and   return   lines,   and   a   reduced   recovery   rate.   Repeated   flushing   usually   clears   such   material.   As   a   preventive   measure,   water   should   be   drawn   from   the   drain   valve  until  it  runs  clear  and  the  installation  of  a  water  filter  should  be  considered.    

4. Inspect  Anode  (annual)  

 

 

• The   purpose   of   the   magnesium   anode   is   to   reduce   the   damaging   effects   of   aggressive   water   on   the   water   heater.     Aggressive   water   will   cause   the   anode(s)   to   erode.     The   anode(s)  must  be  inspected  at  least  annually  to  determine  whether  a  new  anode  should   be  installed.    Use  anode  replacement  parts  supplied  by  Heat-­‐Flo  only.    Heat-­‐Flo  anodes   are  1-­‐1/4  NPT  and  are  made  with  magnesium,  brass,  and  stainless  steel.    There  is  no  steel   in  a  Heat-­‐Flo  anode.  Severe  or  rapid  deterioration  of  the  anode  indicates  very  aggressive   water.     If   this   occurs,   have   the   water   tested   to   verify   whether   it   is   within   the   limits   outlined  on  page  6.    Failure  to  inspect  the  anode  regularly  and  replace  if  necessary  could   result  in  damage  to  the  water  heater.    If  this  unit  is  installed  and  maintained  according  to   the  instructions  and  conditions  in  this  manual,  this  product  will  last  for  a  long  time.  

1.  Close  domestic  water  isolation  valves.  

2.  Drain  the  water  heater  completely  and  allow  it  to  cool  off.  

3.  Remove  the  anode  cover  on  the  front  of  the  unit.  See  figures  on  pages  2  and  3.  The   temperature  control  can  be  turned  to  the  side  to  allow  easier  access.  

4.  After  the  water  heater  has  drained  and  cooled,  remove  the  anode  using  a  1  ¾”  6-­‐point   socket  and  a  breaker  bar.  

5.  Inspect  the  anode  and  replace  if  needed.  The  anode  should  be  replaced  when  more   than  6”  of  core  wire  is  exposed.  The  anode  should  be  replaced  with  a  Heat-­‐Flo  supplied   anode  only.    See  above.  The  brass  hex  on  the  anode  is  1  ¼  NPT  and  installs  into  a  1  ¼   stainless  half  coupling  on  the  shell  of  the  tank.  This  part  will  need  to  be  properly  Teflon   taped  and  coated  with  a  quality  Teflon  based  pipe  sealant.  

6.  Replace  the  inspection  cover.  

7.  Refill  the  water  heater,  and  restore  to  operation.  

8.  Verify  operation  of  boiler  and  water  heater.
