1.2 Introduction

The TEMPRA Boiler is a “room-sealed” appliance: it takes in the air required for combustion and
encloses all the combustion products in an hermetic compartment. The discharge of fumes and
intake of combustion air are managed through air/flue pipes that may be run horizontally in all
directions, or through a concentric flue running vertically or horizontally.

The main components of the boiler are:

- A compact heat exchanger in copper, formed by four pipes with external finning and internal
turbulence activators.

- A combustion chamber insulated to reduce heat loss and thus improve efficiency.

- Nine stainless steel burners, an oxidation- and thermal shock-resistant material specially devel­oped for this product.

- A fan to discharge combustion products and draw in combustion air.

- A boiler thermostat overheat thermostat and frost thermostat.

- A steel room-sealed compartment treated against corrosion, enclosing all the above components.

- An air differential pressure switch which, to ensure safe operation, allows burner ignition only
when the fan functions normally.

- A newly-designed gas ignition valve assembly, comprising a range rated regulator gas valve and a
flame control device. (Ignition is by an intermittent pilot flame; which lights the main burners.)

- An expansion vessel, pump, automatic air vent and air separator .

- A temperature sensor.

- Pressure gauge.

- Pressure relief valve set at 3 bar.
