Note:
If the drain line becomes clogged or frozen, condensate will back-up into the water heater and a "29" 

error code will 

flash

 on the remote controller, ceasing operation. If this occurs, clear the clog or freeze 

so that condensate can freely 

flo

w. Be sure to slope the drain pipe, use the appropriate size pipe, allow 

the proper clearances, and apply freeze prevention measures (when necessary) to prevent the drain 

line from clogging or freezing.
