Bradford-White Corp DS150S Manuel D’Utilisation

 

The thermostat dial is set to its lowest temperature setting when shipped from 
the factory.  Remember that lower temperature settings are more energy 
efficient.  Adjust the temperature by turning the thermostat dial.  It is 
suggested that the starting point setting not be greater than the “

 

” mark on 

the thermostat dial (approximately 120°F [49°C]) as indicated below.  Rotate 
the thermostat dial clockwise 

 

 to increase the temperature setting.  

Rotate the thermostat dial counterclockwise  

 

 to decrease the 

temperature setting.  Adjust the dial until the minimum acceptable temperature 
is achieved (See figure below for approximate temperature settings). 

 

 

 

 
Hotter water increases the risk of scald injury.  Scalding may occur within 
five (5) seconds at a temperature setting of 135

°

 

F (57

° C).  To protect 

against hot water injury, install an ASSE approved mixing valve in the 
water system.  This valve will reduce point of discharge temperature by 
mixing cold and hot water in branch water lines.  A licensed plumbing 
professional or local plumbing authority should be consulted. 

 

Note:  This water heater is equipped with an energy cut out device to 
prevent overheating.  Should overheating occur or the gas supply fail to 
shut off, turn off the manual gas control valve to the appliance and call a 
qualified service technician. 

 

Note:  Whenever the water heater is filled with cold water, condensate will 
form on the cool tank surface and drops of water will fall on the hot burner 
and combustion chamber surfaces producing a “sizzling” noise.  
Condensation is normal and does not indicate a leak.  It will disappear 
when the tank becomes heated.
