INTRODUCTION

Welcome and congratulations on purchasing your YUNCA EROS FLUED GAS HEATER.

Please read the following carefully before attempting to operate the heater and ensure all members of your home understand how this elegant and highly efficient heater functions.

Please fill out and return the registration card promptly.

These instructions should be stored in a convenient safe place for ready reference. If you have any questions regarding your heater please contact your YUNCA EROS dealer.

The YUNCA EROS FLUED GAS HEATER is a listed gas-fired, conventionally vented, room heater tested by independent laboratories to New Zealand standards.

The installation of the YUNCA EROS FLUED GAS HEATER must be carried out by a suitably qualified person and comply with the current New Zealand (Australian installation code) NZS

5261:1996 (AG 601:1998)

CAUTION

: This appliance must be flued to atmosphere. Installation and repair of the

YUNCA EROS VENTED GAS HEATER should be done by a qualified person. The appliance should be serviced at least annually by a qualified service person. Control valve compartments, burners, fan, and air circulating passageways of the EROS must be kept free from any lint and dust build-up to ensure efficient and safe operation of the heater.

DO NOT PLACE ARTICLES ON OR AGAINST THIS APPLIANCE.

DO NOT USE OR STORE FLAMMABLE MATERIALS NEAR THIS APPLIANCE.

DO NOT SPRAY AEROSOLS IN THE VICINITY OF THIS APPLIANCE WHILE IT IS

OPERATIONAL.

To remove internal packaging, refer to page 12 for front door removal.


INSTALLATION

Considerations

The most desirable and beneficial location for a YUNCA EROS HEATER is in the centre of a building, thereby allowing the most efficient use of the heat created.

The location of windows, doors and the traffic flow in the room where the heater is to be located, should all be considered.

If possible a location should be selected that allows the flue pipe to be installed simply and pass through the house without cutting a floor or roof joist.

To obtain maximum heat distribution with any freestanding heater a ceiling fan can be fitted.

Another important consideration when installing the Yunca EROS is availability of power supply to the fan.

When the appropriate position has been selected the unit can be bolted to the floor to ensure that the unit remains upright in the event of an earthquake or similar. A template has been supplied with your heater and should be placed on the floor so holes can simply be drilled through the template. The flue centre is also marked so a plumbob can be used to find the centre of the ceiling flue.

If the heater is being attached to a concrete floor dyna bolts should be used, if the floor is wooden the bolts used should be long enough to go fully through the floorboards and fixed with nuts and washers from the underside.

The earthquake brackets are located at the rear corners of the heater and are exposed by removing the cover.



CLEARANCES

The YUNCA EROS FLUED GAS HEATER should be installed with clearances equal to or greater than those recommended below and comply with NZS 5261/ AG601.

This is to ensure adequate air circulation around the heater and avoid heat damage to wall coverings.

Note: Ensure main gas pipe will not interfere with the removal of fan assembly at the back of the plinth.

(Fig. 3)


CONNECTING THE HEATER TO A GAS SUPPLY

.

Burn only the fuel for which the heater is equipped.

The YUNCA EROS may be shipped from the factory equipped to burn natural gas, Propane or

L.P.G. The data plate affixed to the back of the heater specifies the gas type which the heater is factory equipped for. Fuel Conversion Kits are available from your YUNCA agents.

See Appendix: A for instructions on field conversion from one gas to another. This conversion can only be done by a suitably qualified person.

Gas connection:

The gas inlet is located behind the fan Back Pane. The inlet thread is a female 3/8” BSP.

A separate gas isolation valve should be installed immediately up stream of the connection to the appliance.

WARNING: To stop pipe compounds entering the gas line, do not apply sealing compounds to the first two threads at the tip of any gas connection. All joints should be tested for leaks before operating the heater.


GAS PRESSURE REQUIREMENTS

Correct gas pressure and the use of a properly sized gas supply line is essential for the safe and efficient performance of this appliance. The inlet and outlet pressures at the control must be tested on installation, following the procedure over page.

Note: Improper gas pressure will affect heater performance, flame Colour or cause pilot malfunction.

Natural Gas:

Minimum inlet pressure 1.25 Kpa (5”w.g.)

Maximum inlet pressure 5.0 Kpa (20”w.g.) With supplied inline regulator fitted.

Operating pressure 1.0 Kpa (4”w.g.)

L.P.G. (NZ Only) and Propane

Minimum inlet pressure 2.75 Kpa (11”w.g.)

Maximum inlet pressure 3.5 Kpa (14”w.g.)

Operating pressure 2.5 Kpa (10”w.g.)

CAUTION: Do not use this heater if any part has been under water or exposed to moisture causing corrosion.

A Qualified service technician should inspect the heater and replace any part of the gas system that has been under water.


PRESSURE TESTING:

The pressures listed on the previous page can be tested using a manometer.

To attach manometer, first remove the inspection cover from back panel. The cover is located directly behind the control and is removed by unscrewing the two top screws.

This will expose the back of the control so manometer tubes can be attached to the pressure taps as shown below.

The inlet pressure can be adjusted via in line regulators in the supply to the heater, and the outlet

(operating) pressure by adjusting the valves internal regulator. To locate the valves regulator

adjustment screw the plastic control cover must be removed from the front of the valve. This is done by removing the bottom screw and inserting a small flat head screwdriver into the slot at the top on the front of this cover and pulling the cover off. Refer to fig. 4 below

THERMOSTAT

The thermostat sensing bulb is found on the fan back panel held in a saddle.

In some installations the thermostat sensing bulb may need to be repositioned to accurately sense the room temperature. Reposition in an unobtrusive place.

CONNECTING THE FAN

The fan should be connected to the mains supply (240V 50Hz) via the 3m flex and 3pin plug

MAINTENANCE

A qualified service person recommended by your YUNCA dealer should conduct an annual inspection and undertake any maintenance required on your EROS. Its venting and installation must be checked to keep it running safely and efficiently. The following procedures should be performed only by a qualified service person. The gas supply and electrical power should be isolated whenever any maintenance procedures are undertaken.

Note: the door can only be removed after the heater has been turned off for long enough so that the door has cooled to touching temperature.

Removing The Front Door

1. First the top panel must be removed, to do this grip panel at the front edge and the back corner. Pulling up will disengage the locating pin. Then work the hand position around the panel to disengage all the locating pins.

Care needs to be taken not to damage any panels by keeping the panels from touching each other during this process

2. The side panels must be removed, to do this grip the top of the and pull out to disengage the locating pins. The panel should be swung out to about 20 degrees and then pulled up to release the locating pins at the bottom. Take care to ensure the door is not damaged by the side removal.

3. This will expose the restraining latches at each side. To open these latches lift the butterfly grip forward and twist it through 180 degrees.

4. The front door can now be removed by griping it by its back bottom corners by lifting it away from the heater.

Removing The Glass For Replacement.

1. Remove the front door as described above, and place front down on a soft surface.

2. Remove the bottom front glass retainer by taking out the four screws along the base of the door.

3. To remove the front glass place one hand under it and lift it up and out of the doorframe.

4. New glass with gasket attached can be ordered through your YUNCA EROS agent.

Note: Only recommended heat resistant glass may be fitted.

5. Place replacement glass in position in the reverse order of removal.

6. Replace bottom glass retainers with their respective bolts and screws.

Note: Tighten the screws and bolts alternately, do not over tighten, to avoid damaging glass.


REPLACING THE GASKET.

The YUNCA EROS has a 10mm fibreglass gasket surrounding the front door. Should it ever need replacement, use only the replacement gasket that is available from your YUNCA dealer.

The reference number for this is listed in the parts list.

Procedure.

1. Remove the front door as described on previous page.

2. Remove the existing gasket and clean the channel of all loose material.

3. Lay the gasket in the channel, starting from one end.

4. Replace the door carefully to avoid dislodging the gasket.

Cleaning The Glass

The glass may be cleaned with ordinary household glass cleaner and a soft cloth or paper towel.

Note: Never clean the glass when it is hot. Do not use abrasive cleaners on the glass.

CLEANING THE LOG SET AND FIREBOX.

During the annual inspection and maintenance appointment, the service person should clean dust, lint and any light soot accumulation from the logs and the fire box area. An extra soft brush should be used on the logs as they are extremely fragile. If at any time the logset cannot be removed or installed without force, the cause must be found. The logset must never be forced.

Procedure.

1. Remove front door as described previously.

2. Remove the inner hearth by removing the screws along the lower front and lifting clear.

3. Remove the loose side coals with care. Gently brush clean.

4. Remove the log set from the firebox by lifting it up and out.

5. Brush it gently over a newspaper and carefully place it out of the way.

6. Vacuum cleaner can be used to remove any visible dust and lint from within the firebox area.

7. In and around the pilot light assembly the fine gas ways need to be clean and free from obstruction. The jets may require to be checked for obstructions

8. Replace the logset and then the loose coals.

9. Replace the inner hearth.


10. Replace and relatch the front door, replace the side panels and top.

CLEANING THE TOP AND LOUVRES

Note: If a flue guard kit has been fitted this may need to be removed. This is done by sliding the front half up and out and unscrewing the back half from its brackets.

The top panel is held in place by four retaining pins. The top panel must be removed, to do this grip panel at the front edge and the back corner. Pulling up will disengage the locating pin. Then working the hand position around the panel to disengage all the locating pins.

Care needs to be taken not to damage any panels by keeping the panels from touching each other during this process.

Slide the top panel up the flue until there is sufficient space to vacuum any dust and lint that may be lying under the panel.

This is also a good time to wipe the front louvers with a soft cloth.

CLEANING THE (OPTIONAL) GOLD DOOR/PARTS

The gold finish is very soft. Care must be taken not to damage the gold coating.

Cleaning must be completed using a soft non-abrasive damp cloth.

NEVER use an ABRASIVE on the gold finish. The gold coating can easily be removed with the lightest rub with abrasive material.

INSPECTING THE VENTING

An inspection of the venting system should be made during the annual service appointment.

There must be no blockages and the flue must be in good repair. Any sections that are taken apart for inspection must be reassembled and sealed as required.


CLEANING THE FILTER

This is the one maintenance procedure designed to be carried out by the householder. The filter should be cleaned periodically to maintain an unrestricted air passage to the fan.

The filter is found at the back of the fire (see below). To clean, use a vacuum cleaner or similar to remove any dust or lint build up. The filter is not designed to be removed for general cleaning.

The area behind the fire should be maintained in a clean state. This reduces the possibility of the fan picking foreign matter that will cause fan noise or damage.

HOW TO REMOVE FAN

Fan removal for cleaning.

1. IMPORTANT. Unplug the fan from the power supply.

2. Remove the front plinth by pulling clear of the locating pins.

3. Undo the screws attaching the switch block inside the heater

4. Loosen the four screws holding the Fan Back to the plinth at the back of the heater. Screws should be loosened but do not need to be removed.

5. The Fan Back that contains the fan is removed from the back of the fire by lifting up off the screws.

6. The fan blades can be cleaned of any dirt and grim.

7. Reassemble

The fan assembly should only be disassembled by an electrician or trained Yunca Technician.
