SYMPTOM
UNEXPLAINED SHUTDOWN OF THE APPLIANCE
This appliance contains an Energy Cut-Off Device which reacts when the water in the heat exchanger exceeds the
anticipated temperature limit. Although it is intended to guard against failure of the automatic gas valve, it may be
triggered inadvertently by other causes, especially during the summer months when the inlet water temperature is
unusually high.
SMELL OF COMBUSTION
PRODUCTS
1. Faulty case or terminal seal.
2. Failure to follow Instructions
with regards to openable
windows and doors.
1. Check that the outer case seal -
Part No. 10/17501and terminal
seal - Part No. 31/12299 are in
good condition, replace if
necessary. Ensure the outer
case is correctly positioned.
2. Re-site the appliance.
IMPORTANT NOTE
To ensure continued safe operation, we recommend that if the
pressure relief valve has operated, it should be replaced immediately
However, if the energy cut-off device reacts to a slowly closing automatic gas valve, the shut down of the appliance may
be accompanied by noises from the heat exchanger and pipework. The pressure relief valve located on top of the water
governor may also have vented water into the case. In this situation it is possible that STEAM will come out of the hot
water tap when turned on.
POSSIBLE CAUSE
Excessive resistance of push rod.
SOLUTION
Exchange push rod and seals. Lubricate with Dow
Corning III silicone grease and ensure free movement.
POSSIBLE CAUSE
Failure of appliance thermostat.
SOLUTION
Repair or replace.
