Bradford-White Corp Convection Heater Manual De Usuario

Place the draft diverter over the flue opening at the top of the water heater by 
inserting the tips of the draft diverter legs into the four (4) holes provided in the 
water heater top.  On some models, line up the holes in the draft diverter legs 
with the holes provided on top of the water heater.  Secure the draft diverter to 
the water heater with sheet metal screw. (See Figure 5) 
 
Vent piping must be attached to the draft diverter outlet to connect the water 
heater to the gas vent or chimney.  The following minimum clearances must be 
followed when connecting vent piping: 
 

a) The vent connector must be the same nominal size as the draft           

 

diverter. 

 

b) The vent connector should not exceed 15 feet (4.5m) in length (for        

 

power vent appliances, refer to supplemental instructions), must not       

 

project into the chimney beyond the inner wall and should contain the     

 

least possible number of bends. 

 

c) All horizontal runs should have a minimum rise of ¼ inch(2.1cm/m) per    

foot of run. 

 

d) Joints of vent connectors shall be securely fastened by sheet metal      

 

  screws or other approved methods. 

 

e) All single wall vent connectors must be at least 6” (15cm) from            

 

  combustible surfaces. 

 

f)  Vent connectors made of single-wall metal pipe shall not pass            

 

  through any attic, inside wall, concealed space, or any floor.  When a    

 

  single-wall metal pipe passes through an exterior wall constructed of     

 

combustible material, it shall be guarded at the point of passage by a     

 

ventilated metal thimble at least 4” (10cm) larger in diameter than the     

 

connector.  (Consult National Fuel Gas Code, ANSI Z223.1and/or          

 

CAN/CGA B149, Installation Codes). 

 
A separate vent for each application is strongly recommended.  If combined 
venting of multiple appliances is necessary or if an unusual situation arises, 
consult the National Fuel Gas Code, ANSI Z223.1and/or CAN/CGA B149, 
Installation Codes (latest editions), for sizing and installation information. 

The vent system must be installed properly.  Failure to properly install the 
vent system could result in property damage, personal injury, or death.
