• Do obtain new warning and instruction labels from Sears for 
placement on the blanket directly over the existing labels.
• 
Do inspect the insulation blanket frequently to make certain 
it does not sag, thereby obstructing combustion air flow.
Combustion Air and Ventilation for 
Appliances	Located	in	Unconfined	Spaces
UNCONFINED SPACE is space whose volume is not less than  
50  cubic  feet  per  1,000  Btu  per  hour  (4.8  m3  per  kW)  of  the 
aggregate input rating of all appliances installed...

FIGURE 13.
• Alternatively a single permanent opening may be used when 
communicating directly with the outdoors, or with spaces that 
freely  communicate  with  the  outdoors.  The  opening  shall 
have  a  minimum  free  area  of  1  square  inch  per  3,000  BTU 
per hour (8.3 cm²/kW) of total input rating of all equipment in 
the enclosure. See Figure 14.

•  Louvers  and  Grilles:  In  calculating  free  area,  consideration 
shall  be  given  to  the  blocking  effect  of  louvers,...

This  water  heater  shall  not  be  connected  to  any  heating 
systems or component(s) used with a non-potable water heating 
appliance.
All piping components connected to this unit for space heating 
applications shall be suitable for use with potable water.
Toxic  chemicals,  such  as  those  used  for  boiler  treatment  shall 
not be introduced into this system.
Water supply systems may, because of such events as high line 
pressure, frequent cut-offs or the effects of water hammer have...

Fit T & P valve insulation over valve. Make sure that the insulation 
does not interfere with the lever or block the discharge opening 
of the T & P valve.
Secure all insulation using tape.
Temperature-Pressure Relief Valve
This  heater  is  provided  with  a  properly  certified  combination  
temperature - pressure relief valve by the manufacturer.
The  valve  is  certified  by  a  nationally  recognized  testing 
laboratory  that  maintains  periodic  inspection  of  production  of 
listed...

The temperature-pressure relief valve must be manually operated 
at  least  once  a  year.    Caution  should  be  taken  to  ensure  that 
(1) no one is in front of or around the outlet of the temperature-
pressure relief valve discharge line, and (2) the water manually 
discharged will not cause any bodily injury or property damage 
because the water may be extremely hot.
If  after  manually  operating  the  valve,  it  fails  to  completely 
reset  and  continues  to  release  water,  immediately...

FIGURE 18.
The  vent  pipe  from  the  water  heater  must  be  no  less  than  the 
diameter of the draft hood outlet on the water heater and must 
slope upward at least 1/4 inch per linear foot (21 mm per meter). 
See Figure 19.
FIGURE 19.
All vent gases must be completely vented to the outdoors of the 
structure (dwelling).  Install only the draft hood provided with the 
new water heater and no other draft hood.
Vent pipes must be secured at each joint with sheet metal screws.
There  must  be  a...

Water  heaters  covered  in  this  manual  have  been  tested  and 
approved for installation at elevations up to 7,700 feet (2,347 m) 
above sea level. For installation above 7,700 feet (2,347m), the 
water heater’s Btu input should be reduced at the rate of 4 percent 
for  each  1,000  feet  (305  m)  above  sea  level  which  requires 
replacement of the burner orifice in accordance with the current 
edition  of  the  National  Fuel  Gas  Code ANSI  Z223.1/NFPA  54.

NOTE:  A water temperature range of 120°F-140°F (49°C-60°C) 
is recommended by most dishwasher manufacturers.
The thermostat of this water heater has been factory set at its 
lowest position (PILOT LIGHTING).  It is adjustable and must be 
reset to the desired temperature setting to reduce the risk of scald 
injury.  The mark () indicative of approximately 120°F (49°C) 
is preferred starting point.  Some states have a requirement for 
a lower setting. 
Turn  the  water  temperature  dial  clockwise...

Tank (Sediment) Cleaning
Sediment  build-up  on  the  tank  bottom  may  create  varying 
amount  of  noise  and  if  left  in  the  tank  will  cause  permanent 
tank  failure.  In  some  water  areas,  you  may  not  be  able  to 
drain  all  sediment  deposits  by  simply  draining  the  tank.  In 
these  cases  Mag-Erad  (part  no.  23600)  can  be  used  to  help 
remove the sediment deposits. This may be ordered from the 
Sears  Service  Center.  For  ordering,  refer  to  the Parts Order...
