INTRODUCTION

All Fenix ventilation units have been designed for continuous year round use. In Finland the Enervent appliances have been installed in small premises and detached houses for over 20 years. The popularity of the appliances is increasing year by year. Using knowledge gained over the years, it has been possible to make the Fenix range more and more user-friendly.

The Fenix range is the result of long-term product development. It is extremely versatile and variable.

With the help of this manual it is possible to install the Fenix unit with common functions yourself. We recommend that installation of ventilation units with special functions and extra equipment be carried out by a qualified electrictian.

If in doubt, we recommend that a qualified ventilation engineer performs the installation work.

Before any maintenance on the appliance is carried out, please read the warning on the next page!

GU AR AN TE E

WARNING

After opening the service hatch, wait for two (2) minutes before starting any maintenance work! Although the unit’s power supply is cut when the hatch is opened, the fans still rotate and the electrical heater is still hot for a while.

There are no user-serviceable parts within the control panel, contact a service technician for service and repairs of this part of the unit.

Check the cause of any fault before restarting the unit!

OPERATING PRINCIPLE

The Fenix ventilation unit is based on recuperative heat recovery. This is achieved with a cross flow plate heat exchanger through which the supply air and the exhaust air flow. Heat from the exhaust air is tranfered through an aluminium plate to the supply air.

The efficiency varies from 52 % to 64 %, depending on the proportion and volume of supply air and exhaust air (the heat from the supply air fan is taken into account). Thanks to its high efficiency, the Fenix saves heating energy at the same time as it provides excellent indoor air quality; therefore it pays for itself in a relatively short time.

PLANNING

PLANNING OF THE DUCT SYSTEM

It is recommended that the task of dimensioning the duct system is given to a professional engineer.

The ducts must be large enough, min. Ø 100 mm diameter (approx 4”) to allow a sufficiently low air speed. In particular the outside feed and the waste air ducts need to be large. The size of the outside air duct, waste air duct and the outside air grille must be Ø 160 mm diameter (approx 8”). Do not fit an insect net behind the grille.

Use only approved materials, such as galvanised spiral-weld or plastic pipe, for the duct system. Air valves which are suitable for mechanical ventilation must be used. Air valves with a diameter of 100 mm or larger are to be used for supply and exhaust air.

The outside air should be taken, if possible, from the north side of the building or from a shady place where temperature variations are moderately small.

The waste air should be led out about 90 cm above the roof ridge. Use insulated factory made fittings. A cover or cowl must be installed on the end of the waste air duct to prevent rain water from entering the duct system.

To enable duct cleaning, a sufficient number of access hatches should be placed in the duct system. The access hatch locations should be marked, for example on the roof trusses, to make finding them easier.

The exhaust air valves should be placed in the following locations: Toilet, kitchen, washroom, bathroom, en-suite, clothing storage room, cleaning cupboard and utility room.

The supply air valves should be placed in the following locations: bedroom, living room, separate dining recess, hobby room, dressing room and sauna. We recommend that a supply air valve is installed in the innermost corner of the sauna. The air flow from the valve should be directed above the stove.

The air from a room with supply air will flow through gaps under the doors or “free flow” door grilles to areas with exhaust air. Normally a 20 mm gap under the door is sufficient, except in the sauna where a 100 mm gap is required. Additional supply air can be ducted directly to wood-burning fireplaces (in the sauna) from the outside. The duct must be closable.

Garages or workshops must not be connected into the ventilation equipment of the house; they should have their own extractor system or independent heat recovery unit.

The cooker extractor hood should not be connected into the house ventilation system. (Excess steam and grease will cause blockage of the heat exchanger).

A fan assisted drying cabinet can be connected indirectly to the exhaust valve (drying cabinet - valve attachment) which allows air from both the room and the cabinet to exhaust from the same valve. The volume through the exhaust air valve has to be at least 12 l/s.

Silencers. A silencer 900 mm long is recommended for the exhaust duct, a silencer 600 or 900mm long is recommended for the supply air duct.

Distances between waste air and fresh air openings. Usually fresh air is taken from a north facing wall and the waste air is led out from the roof or opposite wall.

Other methods are acceptable, so long as they fall within the guidelines laid out by the Building Regulations (Example: D2: Finland 2003, extract shown below), or in accordance with your local directives and regulations governing indoor climate and building ventilation.

The diagram shows how to determine the distance between the outside feed into the house and the waste from the house.

EXHAUST AIR CLASSIFICATION OF LIVING AREAS

The leading of waste air from a building is based on the following, exhaust air classification

Class 1 Exhaust air which contains few impurities. The impurities are mainly from

people or structures. Air is suitable for return air and transfer air.

Class 2 Exhaust air which contains some impurities. The air is not used as return air of

other premises but can be lead for example to the toilet and washing room as transfer air.

Class 3 Exhaust air from premises where high humidity, processes, chemicals and

smells essentially lower the quality of exhaust air. The air is not used as return air or transfer air.

Class 4 Exhaust air which contains ill-smelling or unhealthy impurities considerably

more than the acceptable contents of the indoor air. The air is not used as return air or transfer air.

Examples of exhaust air class of living areas Class 1 Office rooms and small adjoining storage spaces, customer service and

teaching premises, meeting and business premises which are non-odorous.

Class 2 Living rooms, dining recesses, coffee kitchens, shops, warehouses of office

buildings, dressing rooms and restaurant premises where smoking is forbidden.

Class 3 Toilets, washing rooms, saunas, apartment kitchens, distribution and teaching

kitchens, copying premises of drawings.

Class 4 Professionally used fume cupboards, grilles and target exhaust air from

kitchens, car garages and driving tunnels, handling rooms of paints and solvent, dirty wash laundries, store rooms of waste food, chemical laboratories, smoking rooms, hotel and restaurant premises where smoking is permitted.

KITCHEN VENTILATION

A normal cooker hood is installed over the kitchen stove. The hood should be used only when cooking. It is still necessary to install an extract vent, connected into the general ventilation system. The extract air volume should be 20 l/s. The cooker hood should not be connected to the Fenix ventilation unit.

If needed the cooker hood can be connected to the Fenix ventilation unit exhaust air duct, for instance in high-rise buildings where it is difficult to install a separate duct for the cooker hood. Use of separate cooker hood or a combination of a cooker hood and an extractor is recommended to ensure sufficient suction effect.
