IMPORTANT INFORMATION & WARNINGS

SAFETY DEVICES

The water heating system is supplied with various safety devices including temperature sensors, overheat sensors

and switches and a Pressure & Temperature Relief (PTR) valve. These devices must not be tampered with or

removed. The water heating system must not be operated unless each of these devices is fitted and is in working

order.

EXCESSIVE DISCHARGE FROM SAFETY DEVICES

Pressure & Temperature Relief (PTR) Valve

It is normal and desirable that this valve allows a small quantity of water to be discharged during the heating cycle.

If it discharges more than a bucket of water during a 24 hour period or discharges continuously there may be

another problem.

If the valve dribbles continuously, try easing the valve gear for a few seconds as described above. This may

dislodge any foreign matter and alleviate the problem.

If the valve discharges at high flows, especially at night, it may be as a result of the water pressure exceeding the

design pressure of the water heater. Ask your installer to fit a Pressure Limiting Valve (PLV).

Expansion Control Valve (ECV) - if fitted

It is normal and desirable that this valve allows a small quantity of water to be discharged during the heating cycle.

If it discharges more than a bucket of water during a 24 hour period or discharges continuously there may be

another problem.

If the valve leaks continuously, try easing the valve gear for a few seconds. This may dislodge any foreign matter

and alleviate the problem. If this does not alleviate the problem contact Rinnai.

Operate the easing gear regularly to remove any lime deposits and to verify that it is not blocked.

DO NOT tamper with or remove safety devices.

DO NOT operate the water heater unless all safety devices are fitted and in working order.

DO NOT block or seal the PTR Valve and drain pipe.

Pressure & Temperature Relief (PTR) Valve

This valve is located near the top of the water heater

and is essential for safe operation. It is normal for the

valve to release a small quantity of water through the

drain line during heating.

However, continuous leakage of water from the

valve and its drain line may indicate a problem with

the water heater.

Never block the outlet of the PTR valve or it’s drain line for any reason. The easing gear must be

operated at least every 6 months to remove lime deposits and verify that it is not blocked. Failure

to do this may result in the water heater failing.

If the valve does not discharge water when the easing gear lever is opened, or does not seal again

when the easing gear is closed, attendance by an authorised person must be arranged without

delay. The PTR valve is not serviceable.

NEVER replace the PTR valve with one which has a higher pressure rating than is specified for your

water heater.

WARNING

Twist cap until water

flows from drain line

Lift lever until water

flows from drain line

(Lower lever gently!)
