Dewhot | Gas geyser manual

1.  Open the battery box and insert two ‘D’ 

Cell sized batteries 

2.  Open both the cold and hot water 

valve. Close the water Inlet valve after 
you make sure the cold water is flowing 
out through the water outlet and the 
ignition pins fire up. 

3.  Open the gas supply 

4.  Open the water inlet valve and 

the geyser will ignite immediately. 
Sometimes because there is air in the 
gas pipe, it may not ignite the first time, 
so, try two or three times. 

5.  By closing the water inlet or outlet 

valve the gas heater will stop working. 
If needed again, just re-open the water 
inlet valve or water outlet valve. Please 
note that the temperature of hot water 
flowing out is higher so wait for the 
temperature to stabilise. 

6.  This gas geyser may only be used for 

short delivery periods and may not be 
used for the purpose of supplying hot 
water to a bath or washing machine. 

7.  This gas geyser may only be installed 

in a room if the room meets the 
appropriate ventilation requirements 
(refer to SANS 10087-1) 

8.  This gas geyser shall not be 

connected to a flue.
