to do so may cause damage to the gas control valve causing it to malfunction.

Leak Testing the Connection

Plug the end of the consumer piping gas and leak test all joints.
Use a soapy solution to test all gas connections. If a leak is present bubbles will form at the leak
point. When finished remove any residue with a rag. Prevent any soapy solution from coming in
contact with electrical components.
CAUTION

ELECTRICAL SUPPLY

If a power point is used it MUST be 230 V, rated at 10A and MUST be earthed.
This power point MUST NOT be located above the heater. The heater engine
is fitted with a 1.5 metre power cord and three pin plug which can exit the
appliance from either the lower left or right hand side of the heater as required.
