entis INTRODUCTION

Welcome, and congratulations on purchasing your YUNCA entis (Fuzzy Logic) 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 (back page).

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 dealer.

The YUNCA entis (FuzzyLogic Control) FLUED GAS HEATER is a gas-fired, conventionally vented, room heater tested by independent laboratories to Australian and New Zealand standards.

Electronic ignition and operation is by an infra-red remote control hand piece (pages 13-15). However if your remote is mislaid or damaged there is a convenient manual control panel (page 12) in the right hand side of the air vent, below the fascia panel. Both the remote and the control panel feature “kiddylock” controls for added peace of mind.

The Yunca entis incorporates a two-speed automatic fan boost. We highly recommend the use of the fan boost for greater heating efficiency. When the firebox is at an optimal temperature an automatic sensor starts the fan (on low or high speed depending on the setting, refer diagram below). Note : The fan will continue to run until the unit has cooled down. If the fan is not required then having the switch in the middle position will turn the fan boost off.

low (auto) off left middle high (auto)

right

Should power not be available for any reason, battery back up through two “D” sized batteries ensures the fire will continue to operate (without the fan boost). Ref page 12.

The installation of the YUNCA entis FLUED GAS HEATER must be carried out by a suitably qualified person and comply with the current New Zealand installation code, NZS 5261:2003/AG 601:2002.

CAUTION

:

This appliance must be flued to atmosphere .

Installation and repair of the YUNCA entis GAS HEATER must be carried out 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 entis 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.

(This particularly applies to the remote control handpiece!)

DO NOT USE OR STORE FLAMMABLE MATERIALS NEAR THIS

APPLIANCE.

DO NOT SPRAY AEROSOLS IN THE VICINITY OF THIS APPLIANCE

WHILE IT IS OPERATIONAL.

entis INFRA-RED REMOTE CONTROL with AUTO TIMER.

POWER ON/OFF: First check that the two AAA batteries are inserted. The remote may appear to be on, but it is likely that is not so. To turn on the remote control (it is protected with a “kiddy lock”), press and hold the POWER button for about 2 seconds until “off” disappears from the screen, then release to unlock the safety feature. One short press of the POWER button will turn on power to the remote control, and also start the fire on the MANUAL - HIGH setting. Current mode / settings will be displayed. The fire will always start in manual operating mode on a high setting. (Also refer to the next page for further information). There is an audible beep when the fire receives a signal from the remote, range is approximately 5 metres.

CLOCK SETTING: Press the CLOCK button once (“clock” in the display will start flashing). Press

WEEK to set the week day, press HOUR to set the hour, taking care to check if on a.m. or p.m. Press

MIN to set the minute (holding the button down will advance the minutes quicker). Press CLOCK to save the setting.

MANUAL “FLAME” OPERATING MODE h as three settings: High, Medium, Low. Heat output is fixed to the setting and needs to be adjusted manually by pressing TEMP control “ – “ and “ + “ buttons.

“FUZZY LOGIC” OPERATING MODE r eplaces the traditional thermostat operation with six “comfort levels”. Press MODE to switch between Manual and Fuzzy Logic , and use the TEMP “ – “ and “ + “ buttons. Choose the comfort level that best suits your needs. Every now and then the fire will give a short boost of heat and then return to your chosen setting. This is the most economical way to operate your Yunca Fuzzy Logic control fire.

HINT : The two speed fan is designed to quickly transfer heat around the room and ensures the most economic gas use. The three-position switch (LOW/OFF/HIGH) is located on the fan box (ref page 3), and is accessible from near the centre of the bottom air vent.

AUTO FUNCTION : To set this feature you will need to ensure the remote control is on (as advised above), and ensure the CLOCK time and day are correctly set. PLEASE NOTE: If a key is not pressed for 7 seconds, the programming will “time out” and you will need to re-start the process.

Set times to Start and/or Stop the fire with a choice of up to two daily programme settings ( PROG1 and

PROG2 ). You can choose to use only PROG1 if only one setting is needed. Heat output on Auto is initially run in manual control, and once the fire is operating you can then switch to the more economical

Fuzzy Logic.

EXAMPLE : Set PROG1 to start at 6:00 am, stop at 8.00am. Set PROG2 to start at 4.30pm, stop at

10.30pm Monday to Friday. Both PROG1 and PROG2 may have different settings programmed for the weekend if required.

TO SET: Press PROG1 to set the “timer on” setting (Mon-Fri). Now choose the desired heat output

(High, Med or Low) Press HOUR button, making sure you have chosen the correct a.m. or p.m. time, then press MIN button (increases in 10 minute steps) to set the start time. Press PROG1 again and use the HOUR / MIN buttons to set the stop time. Press CANCEL at any time to clear the setting currently on screen (i.e.either Start or Stop). If you are not setting weekend programming, just press PROG1 to save your settings and exit the programming function.

If you wish PROG1 to operate on Saturday and Sunday, press WEEK button to set start time, using

HOUR and MIN buttons as described above. Then press PROG1 again to set the weekend stop time, and press PROG1 once more to save your settings and exit the setting mode.

Continue as above using PROG2 if required. To check the programme settings press either Prog1 or

Prog2.

Revised 22-08-07

Yunca entis instal Aug07 Page 13 of 23

AUTO FUNCTION CONTINUED: Once the times are set, press the grey AUTO SET button and leave the remote near, but not on , the fire or the fire will not operate automatically. When the AUTO SET button is pressed you will hear a long beep. When the fire is not operating the green light on the front control panel (Page 12) will flash slowly to show AUTO is set, and you will see the AUTO symbol display on the LCD screen of the remote control unit.

IMPORTANT:

Press AUTO SET button again to cancel the auto feature or the fire will continue to run on the automatic settings, even if the remote is “off” .

NOTE – Even when AUTO SET is activated (i.e. the display shows AUTO on the remote and the green light on the fire is flashing) you can continue to operate the fire (i.e. turn it on and off, change mode and heat output) without affecting the automatic feature settings. You are effectively temporarily overriding the automatic control, e.g. if you wish to stop the fire running at an earlier time.

MAINTENANCE .

A qualified service person should conduct an annual inspection and undertake any maintenance required on your entis heater. The venting and installation must be checked to keep it running safely and efficiently. The gas supply and electrical power should be isolated whenever any maintenance procedures are undertaken.

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

Before attempting the following maintenance procedures, be sure to follow instructions on page

5 to avoid damage to your fire.

REPLACING THE GLASS

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

2. Remove the four screws holding the glass retainer.

3. The glass and old thermotape seal can be lifted clear and discarded.

4. New glass (1610EIB) and thermotape seal (1611EE) can be ordered through your YUNCA agent.

Note: Only recommended heat resistant glass may be fitted.

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

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

Screws and spire clips may need replacing if suitable assembly compression cannot be achieved.

CLEANING THE GLASS

The glass may be cleaned with damp paper towels. Ceramic glass cook top cleaner may also be used. The inside of the glass may also need cleaning from time to time (refer page 5 for glass door removal information).

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

CLEANING THE CHASSIS

The enamelled chassis may need cleaning from time to time to remove a white film (refer page

5 for glass door removal information). The chassis is enamelled so a wipe over with a damp cloth when the chassis is cool will be sufficient.

REPLACING THE DOOR ROPE (GASKET)

.

The YUNCA entis has a 10mm fibreglass gasket (part number 1608EE) surrounding the front glass door. Should it ever need replacement, use only the replacement gasket that is available from your YUNCA dealer.

Procedure:

1. Remove the glass door as described on page 5.

2. Unscrew the bottom glass retainer.

3. Remove the existing gasket.

4. Fit new gasket ensuring the gasket is not stretched.

5. Replace the glass retainer.

6. Replace the door.

Revised 22-08-07

MAINTENANCE – cont.

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.

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 logs cannot be removed or installed without force, the cause must be found. The logs must never be forced.

Procedure:

1. Remove glass door as described on page 5.

2. Remove the complete log set from the firebox by lifting it up and out. Brush it gently over a newspaper and carefully place it out of the way.

3. The bark tray and heat baffle can be removed by undoing the attachment screws and lifting out.

4. With firebox empty, a vacuum cleaner can be used to remove any visible dust and lint from within the firebox area.

5. Replace the heat baffle and bark tray.

6. Replace log set.

7. Replace the glass door.

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.
