ABOUT YOUR WATER HEATER

WARNING

This water heater is not intended to be operated, adjusted or tampered with by young children or infirm persons. Young children should be supervised to ensure they do not interfere with the water heater.

SAFETY

Do not store flammable or combustible materials near the water heater. Flammable liquids (such as petrol), newspapers and similar articles must be kept well away from the water heater and the draught diverter.

Do not use aerosols, stain removers and household chemicals near the water heater whilst it is working. Gases from some aerosol sprays, stain removers and household chemicals become corrosive when drawn into a flame.

Do not store swimming pool chemicals, household cleaners, etc., near the water heater.

Do not place anything on top of the water heater or in contact with the draught diverter. Ensure the draught diverter is not obstructed in any way at any time.

Do not use Propane / Butane gas mixtures in a Propane model. A Propane model is designed to operate on Propane only. The use of Propane / Butane mixture, such as automotive LPG fuel, in a Propane model is unsafe and can cause damage to the water heater.

This water heater is supplied with a thermostat, an over-temperature cut-out, and a combination temperature pressure 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 is in working order.

The warranty can become void if relief valves or other safety devices are tampered with or if the installation is not in accordance with these instructions.

TO TURN OFF THE WATER HEATER

If it is necessary to turn off the water heater:

Shut down the gas control (refer to “Close Down Procedure” on page 27).

Close the gas isolation valve at the inlet to the gas control.

Close the cold water isolation valve at the inlet to the water heater.
