During  Installation  of  this  water  heater…

Hot  and  Cold  Pipe  Insulation  Installation

Insulation  Blankets

Insulation  blankets,  available  to  the  general  

public  for  external  use  on  gas  water  heaters,  

are  not  necessary.  The  purpose  of  an  

insulation  blanket  is  to  reduce  the  standby  

heat  loss  encountered  with  storage  tank  

heaters.  This  water  heater  does  not  store  water  

making  an  insulation  blanket  unnecessary.  

The  manufacturer’s  warranty  does  not  cover  

any  damage  or  defect  caused  by  installation,  

attachment  or  use  of  any  type  of  energy  

saving  or  other  unapproved  devices  (other  

than  those  authorized  by  the  manufacturer)  

into,  onto  or  in  conjunction  with  the  water  

heater.  The  use  of  unauthorized  energy  saving  

devices  may  shorten  the  life  of  the  water  

heater  and  may  endanger  life  and  property.

The  manufacturer  disclaims  any  responsibility  

for  such  loss  or  injury  resulting  from  the  use  

of  such  unauthorized  devices.

CAUTION:  If  local  codes  require  the  

application  of  an  external  insulation  

blanket  to  this  water  heater,  pay  careful  

attention  to  the  following  so  as  not  to  

restrict  the  proper  function  and  operation  

of  the  water  heater:

 

  

Do  not  cover  the  air  inlet,  flue  outlet  or  
operating  and  warning  labels  attached  to  
the  water  heater  or  attempt  to  relocate  them  
on  the  exterior  of  insulation  blanket.

WARNING:  If  local  

codes  require  external  

application  of  insulation  

blanket  kits  the  

manufacturer’s  

instructions  included  

with  the  kit  must  be  

carefully  followed.

NOTICE:  The  hot  and  cold  

pipes  should  be  insulated  as  

shown  to  provide  additional  

freeze  protection.

WARNING:  In  case  the  

pipe  insulation  is  not  rated  

for  the  appropriate  

weather  conditions  install  

electric  heat  tracing  or  

equivalent  to  prevent  

freezing  of  the  pipes.  Do  

not  insulate  or  block  drain  

valve  on  the  hot  outlet  

fitting.  If  the  pipes  are  

allowed  to  freeze,  the  water  

heater  and  the  pipes  may  

malfunction  or  leak  due  to  

freezing  water.
