American Water Heater GAS-FIRED COMMERCIAL WATER HEATER 用户手册

This water heater has been shipped with a draft diverter for which it was 
designed with reference to the horizontal and vertical planes.  If removed, the 
draft diverter shall be replaced in the same position and secured to the jacket 
top by the screws with which it was installed. 
 
This water heater must be connected to a masonry chimney or venting system 
approved by local codes or ordinances.  The vent connector used to attach 
the draft diverter outlet to the chimney or approved vent must be of the same 
diameter as the draft diverter outlet or larger.  For proper venting in certain 
installations, a larger vent connector may be needed.  Consult venting tables 
in ANSI standard (Z223.1-or latest edition), National Fuel Gas Code and 
CAN/CGA (B149.1 or B149.2-latest editions), or local code officials for proper 
application for your area. 
 
Flue Damper 
 
Refer to Figure 5 and follow these instructions: 
 

 
1.  Remove the damper from the accompanying box shipped within the crate. 
 
2.  Locate the collector outlet on top of the water heater. Place the damper 
  over the collector outlet and rotate as necessary to a position in which the 
  damper wiring plug can be fully engaged with the connector on the side of 
  the water heater. 
 
3.  Remove clip which holds damper vane closed.  If supplied this type of vent 
     damper will then open by itself. 
 
4.  Being certain that the damper vane will travel freely from the “closed” to    
   “open” position, secure the flue damper to the jacket top with sheet metal  
   screws.  Note: Some dampers require an additional bracket to assure level 
 installation. 

 

 

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