of this manual) for servicing and spare parts for your gas 
continuous flow hot water system. 

warning

Turn off the electrical power supply and close the manual 
gas control valve and the manual water control valve before 
servicing. 

•  Clean the cold-water inlet filter.  

(Refer to the diagram below right) 

•  Be sure that all openings for combustion air are free from 

blockage. If blocked, remove the obstruction. 

•  Check that the opening for exhaust is not blocked. If 

blocked, shut off the water heater’s combustion. Wait 
until the system has completely cooled before removing 
the obstruction. DO NOT touch while the system is 
running – extremely high temperature can cause  
severe burns.  

•  Check the gas pressure. 
•  Keep the area around the system clear. Remove any 

combustible materials, gasoline or any flammable 
vapours and liquids. 

Water heater draining and filter cleaning

2.   Turn off the power supply to the system. 
3.   Close the manual water shut off valve. 
4.   Open all hot water taps in the house (bathroom, kitchen, 

laundry room, etc.). When the residual water flow has 
ceased, close all hot water taps.

heater’s drain plugs. Unscrew the drain plugs to drain all 
the water out of the water heater. 

6.   Wait a few minutes to ensure all water has  

completely drained. 

7.   Clean the filter: Check the water filter located within the 

cold inlet. With a tiny brush, clean the water filter of any 
debris which may have accumulated and reinsert the filter 
back into the cold water inlet. 

8.   Securely screw the drain plugs back into place.  

Hand- tighten only.
