SECTION III:  GENERAL INFORMATION 
 
FEATURES 
 
1.  Porcelain enamel lined tank provides corrosion protection with a tough glass lining on the interior of the tank. 
2.  Magnesium anodes provide an extra measure of protection and extends tank life. 
3.  Direct Vent design with an induced draft blower.  Flue gases are exhausted and combustion air is taken from outside 
the building through 3” or 4” PVC, CPVC, or ABS pipe.  Maximum venting distance for each pipe of 40 feet with one 
elbow for 3” diameter pipe and 55 feet with one elbow for 4” diameter pipe.  May be horizontally or vertically vented.  
See venting section for complete details. 
4.  Hand Hole Cleanout allows inspection of tank interior and allows the removal of lime and sediment deposits. 
5.  Honeywell Integrated Water Heater has the following features: 
  Attractive digital water heater display on control panel for precisely setting and displaying the temperature setpoint.  
Pressing temperature up and down buttons changes the temperature setpoint.  Temperature format may be 
displayed in degrees F or degrees C. 
  Single control board with  plug in wiring controls temperature, ignition, and induced draft blower operation. 
  Reduced number of parts for servicing and wiring. 
  Plug in wiring reduces chance of miswiring. 
  Water heater display will show diagnostic codes in the event the water heater needs servicing.  Aids in diagnosing 
and servicing the water heater.  Temperature of the tank sensors can be monitored in the Service Mode. 
  Water heater display can show up to 10 previous error codes to further aid in servicing the water heater. 
 
Keep clear of combination temperature and pressure relief valve discharge line outlet.  The discharge may be 
hot enough to cause scald injury.  The water is under pressure and may splash. 
 
For protection against excessive temperatures and pressure, install temperature and pressure protective equipment 
required by local codes, but not less than a combination temperature and pressure relief valve certified by a 
nationally recognized testing laboratory that maintains periodic inspection of production of listed equipment or 
materials as meeting the requirements of the Standard for Relief Valves and Automatic Gas Shutoff Devices for Hot 
Water Supply Systems, ANS Z21.22
 and the Standard CAN1-4.4 Temperature, Pressure, Temperature and 
Pressure Relief Valves and Vacuum Relief Valves
.  The combination temperature and pressure relief valve must be 
marked with a maximum set pressure not to exceed the maximum working pressure of the water heater.  The 
combination temperature and pressure relief valve must also have an hourly rated temperature steam BTU 
discharge capacity not less than the hourly rating of the water heater. 
 
Install the combination temperature and pressure relief valve into the opening provided and marked for this purpose 
on the water heater. 
 
Note:  Some models may already be equipped or supplied with a combination temperature and pressure relief valve.  
Verify that the combination temperature and pressure relief valve complies with local codes.  If the combination 
temperature and pressure relief valve does not comply with local codes, replace it with one that does.  Follow the 
installation instructions above on this page. 
 
Install a discharge line so that water discharged from the combination temperature and pressure relief valve will exit 
within six (6) inches (15.2 cm) 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 combination temperature and 
pressure relief valve and the discharge line.  The discharge opening must not be subjected to blockage or freezing.  
DO NOT
 thread, plug or cap the discharge line.  It is recommended that a minimum clearance of four (4) inches 
(10.2 cm) 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.
