       22 . A water heater comprising: 
 a water container;    a combustion chamber adjacent the water container;    a burner associated with the combustion chamber;    a blower assembly located to receive combustion products generated by the burner;    an intake air conduit sealingly connected to the combustion chamber and having a combustion air intake opening located adjacent an upper portion of the water heater, said combustion air intake opening being covered with a perforated cap; and    a dilution air conduit sealingly connected to the blower assembly and having a dilution air intake opening located adjacent a lower portion of the water heater.    
   
   
       23 . A water heater comprising: 
 a water container;    a combustion chamber adjacent the water container;    a burner associated with the combustion chamber;    a blower assembly located to receive combustion products generated by the burner;    an intake air conduit sealingly connected to the combustion chamber and having a combustion air intake opening located adjacent an upper portion of the water heater;    a dilution air conduit sealingly connected to the blower assembly and having a dilution air intake opening located adjacent a lower portion of the water heater; and    wherein the intake and dilution air conduits are substantially PVC, ABS and/or CPVC.    
   
   
       24 . A water heater comprising: 
 a water container;    a combustion chamber adjacent the water container;    a burner associated with the combustion chamber;    a blower assembly located to receive combustion products generated by the burner;    an intake conduit sealingly connected to the combustion chamber and having a combustion air intake opening located adjacent an upper portion of the water heater, said combustion air intake opening being covered with a perforated cap, the intake conduit comprising a substantially vertically oriented portion extending along at least a portion of the length of the water heater, and a substantially horizontally oriented portion extending from the vertically oriented portion to an opening in the combustion chamber; and    a dilution air conduit sealingly connected to the blower assembly and having a dilution air intake opening located adjacent a lower portion of the water heater, the dilution air conduit comprising a substantially vertically oriented portion extending along at least a portion of the length of the water heater, and a connector portion extending between the blower assembly and the substantially vertically oriented portion.    
   
   
       25 . A water heater comprising: 
 a water container;    a combustion chamber adjacent the water container;    a burner associated with the combustion chamber;    a blower assembly located to receive combustion products generated by the burner;    an intake conduit sealingly connected to the combustion chamber and having a combustion air intake opening located adjacent an upper portion of the water heater, the intake conduit comprising a substantially vertically oriented portion extending along at least a portion of the length of the water heater, and a substantially horizontally oriented portion extending from the vertically oriented portion to an opening in the combustion chamber;    a dilution air conduit sealingly connected to the blower assembly and having a dilution air intake opening located adjacent a lower portion of the water heater, the dilution air conduit comprising a substantially vertically oriented portion extending along at least a portion of the length of the water heater, and a connector portion extending between the blower assembly and the substantially vertically oriented portion; and    wherein the intake and dilution air conduits are substantially PVC, ABS and/or CPVC.
