Page 7: How Your Water Heater Works
HOW YOUR WATER HEATER WORKS The water heater consists of a gas burner, a combustion chamber lined with refractory tiles and a heat-exchanger made of finned copper tubes. Hot flue gases from the burner pass between the fins on the heat exchanger tubes and heat is transferred first to the fins and then by conduction into the water. -

- Page 14 INSTALLATION COLD WATER SUPPLY Water Heating Applications Where the cold water supply pressure exceeds that shown in the table below, an approved pressure limiting valve is required and should be fitted as shown in the installation diagram (refer to diagram on page 17). Mechanical/Process Heating Applications A cold water feed regulator (Pressure Reducing Valve) should be installed on the cold water make up line.
- Page 15 INSTALLATION HOT WATER DELIVERY (WATER HEATING APPLICATIONS) This water heater can deliver water at temperatures which can cause scalding. It is necessary and we recommend that a temperature limiting device be fitted between the water heating system and the hot water outlets in any ablution and public areas such as bathrooms, ensuites or public amenities, to reduce the risk of scalding.

CONNECTIONS – PLUMBING IMPORTANT: When installing a new water heater to an old or existing system, it is a requirement that the system and its equipment be thoroughly inspected and if necessary, drained and flushed with clean fresh water, before the new water heater is connected. - Page 18 CONNECTIONS – PLUMBING The table below provides indicative pipe and pump sizes for typical installations Minimum Manifold Header Model Pump Branch Size Size Required (mm) Speed inches Series Unit Units Units Units 20-60B 20-60B 1¼ 32-80B 1¼ 32-80B 1¼ PUMP SELECTION In order to obtain the best possible water flow in the system a correctly sized pump must be installed.
- Page 19 CONNECTIONS – PLUMBING In locations where water pipes are prone to freezing, the drain line must be insulated and not exceed 300 mm in length. In this instance, the drain line is to discharge into a tundish through an air gap of between 75 mm and 150 mm.
