CAUTION! 

If this water heater is left in an operating condition and unused for two weeks or more, a 
quantity of hydrogen (which is highly flammable) may accumulate in the top of the water 
cylinder.  To dissipate this gas safely it is recommended that a hot tap be turned on for 
several minutes at a sink, basin or bath, but not a dishwasher, clothes washer or other 
appliance.  During this procedure there must be no smoking, open flame or any other 
electrical appliance operating nearby.  If hydrogen is discharged through the tap it will 
probably make an unusual sound as with air escaping. 

 

SAFETY INFORMATION: 

 

WARNING: 

For safe performance this water heater is fitted with: 

1. Thermostat. 
2.  Over-temperature energy cut-out. 
3.  Combination pressure & temperature operated relief valve. 

These devices must not be tampered with or removed. 
The water heater must not be operated unless each of these devices is fitted and in 
working order. 
Relief valves should be checked for adequate performance or replaced at intervals not 
exceeding 5 years, or less in areas where there is a high incidence of water deposits.  The 
lever on the relief valve must be pulled to operate the valve at least once every 6 months. 
Failure to operate the relief valve easing gear at least once every six (6) months may result 
in the water heater exploding. 
 

IMPORTANT 

The relief valve and its drain outlet pipe must not be sealed or blocked.  It is normal for 
valve to overflow during heating cycle.
