CONGRATULATIONS
Thank you for purchasing your new CHAD-O-CHEF Gas Fireplace manufac-
tured to high standards and tested for compliance with SANS 10087-1
The manufacturer and /or its agents and distributors will not be held re-
sponsible for injuries or damages caused by faulty or incorrect installation or
use of the appliance.
1. This fireplace provides radiant and convection heat both efficiently and safe-
ly, using the latest technology, without the need of a flue. This appliance consumes
oxygen when in use and it is important that it is only used in a well ventilated
area, for the efficient performance of the appliance and for the safety of the
occupants of the area.
2. No permanent ventilation is required if the room is 97m³ or larger,but an
opening window or louver is required. Should the room size be smaller than 97m³
then permanent ventillation will be required. This volume may include adjacent
spaces connected by permanent openings and not separated by a door.
3. The fireplace must not be installed in an enclosed bathroom.
4. The fireplace must not be installed in a bedroom without the provision of
permanent ventilation.
5. Where applicable, the min. free area of ventilation must be 13 cm² per mJ of
heat input. The heat input of other gas, wood, coal or paraffin appliances must be
included in the calculations. It is the installer’s responsibility to do these calculations.
6. This appliance may only be installed by a registered LP Gas installer
and must comply with the requirements of SANS 10087-1. Ask to be shown
the installer’s card with his registration number, before allowing the installation work
to commence and make a note of his QCC number. Upon completion of the installa-
tion, the installer is required to explain the operational details of the appliance to-
gether with the safety instructions. You will be asked to sign acceptance of the in-
stallation and be provided with a completion certificate. You should only sign for ac-
ceptance of installation, upon commitment from the installer, that it complies with
SANS 10087-1 and is to your satisfaction.
Note that if the guarantee card is not signed by yourself and the installer and
returned to the manufacturer, the product guarantee is invalid.
7. On initial lightup of your new fireplace, the “newness” will burn off within the
first few hours of operation. During this period some smoke may be emitted from the
unit, this should be no cause for concern. Accordingly, the room should be well
vetilated with all windows open during this period.
8.Humidity levels will rise with the use of your fireplace, but with the usual
dryness of winter, it will surely be welcomed. Should the humidity become
overbearing, open the windows for a short period to ventilate the room.

INSTALLATION REQUIREMENTS
Your VFDI800-N Fireplace is designed to drop into a hole prepared in a
masonry construction.
In order to function correctly the unit needs adequate ventilation
holes to be cut into the masonry construction housing the unit
(2x 100mm holes)
Choosing a site
This fireplace may be installed in any room in a home except in enclosed bath-
rooms where the humidity levels are too high. (See page 2)
Avoid areas where there are strong draughts, which may be generated by out-
side doors. It is recommend that the fireplace should not be installed within 500mm
of any air vent, as this could affect the working of the ODS.
An outside wall is most convenient for the gas installation.
Clearances to combustible materials
Combustible materials are defined as wood, fabrics, or other materials likely to
burn when exposed to flame. Any other material which is likely to discolour ,melt, or
lose shape when exposed to moderate heat, should fall into the same category.
Min clearance to the sides 100 mm
Min clearance to the sides for curtains & fabric 500 mm
Min clearance to the ceiling 800 mm
Min clearance to a floor ( including carpet ) 100 mm
Min clearance to combustible furniture in front 1000mm
A masonry shelf may be fitted 300mm above the fireplace but under no cir-
cumstances should any electrical equipment such as plasma screen TV sets be po-
sitioned on the wall above. Any ornaments positioned above the fireplace must be
able to withstand the elevated temperatures and moisture. No combustible materials
whatsoever must be used or placed above the fireplace.

INSTALLATION INSTRUCTIONS
FOR QUALIFIED GAS INSTALLER
Unpacking
Carefully undo strapping to separate loose parts and remove all plastic protec-
tive sheeting.
Positioning and Sizing
Confirm that the size of Fireplace chosen is the right size for the room.
Build up a masonry platform to the customers design, with a suitable hole to
drop the fireplace into, so that it rests on the surrounding rim.
Provide a vent for the primary air to the burner by means of a hole, with a
minimum size of 50 sq cm, leading into the cavity below the unit.
Connect up according to SANS 10087-1
Connect a copper pipe from the gas bottle via a regulator, complying with
SANS 1237, to the Ø8 compression fitting on the control valve, taking into
account the distance from the gas tank, to calculate the size of the copper
pipe.
Setting up
1. Insert the burner with the venturi facing the gas jet.
2. Fill the burner with the special black radiant ceramic ash or glass chips.
3. Spread the decorative stone or ceramic evenly around the burner.
NOTE: Should the burner become dislodged, replace it making sure that it
rests flat on the base plate, without any ceramic or stone coming between it and the
plate.
4. Place pebbles in a single layer, double row, spread across the burner,
allowing about 10mm gaps between them.
Or place coals in a single layer, double row, spread across the burner,
adding a second row on top, allowing about 10mm gaps between them.
Use only the number of pebbles or coals supplied.
Testing and Commissioning
Turn on the gas supply and test for leaks with soapy water.
Ensure that the WORKING PRESSURE is 2,1 kPa at the control valve.
See checklist.
Briefing the customer
All instructions must be handed over to the user for safekeeping. Instruct the
customer how to turn the gas on and off and how to light and control the fire.
After commissioning the unit the customer should be instructed on the safe use of it
and the need for regular servicing. Frequency of service depends on usage, but
must be carried out at the first sign of malfunction and at least once in 2 years.
Identify the Valve of the Fireplace using the pictures on pages 5-7 and use the
Operating and Pressure Testing Instructions as appropriate.

 Ensure that there is adequate ventilation (See Page 2)
CAUTION
Do not tamper with jets, burners or regulator settings. NEVER MODIFY OR
BEND THE THERMOCOUPLE TO MAKE THE PILOT STAY ALIGHT. CHAD-O-
CHEF products are preset and tested to function efficiently and are approved
by the LPGSA.
Should a burn back occur, i.e. the jet catching alight at the entry to the burner
with a noticeable loud rushing sound: Turn the gas off immediately and re-
light after 1 min. If condition persists, contact your gas installer.
Should a leak in the gas be detected, turn off the gas at the gas cylinder, and
contact your installer immediately.
Should there be an unexplained shutdown, which could be the result of insuf-
ficient oxygen in the room, shut off the gas supply, then open windows and
doors in the room, wait 5 min before attempting to restart. If condition per-
sists, contact your gas installer.

WARNING
This appliance shall not be installed in separately enclosed bathrooms.
WARNING
This is an un-vented gas fired heater. It uses air (oxygen) from the room
in which it is installed. Provisions for adequate ventilation must be
provided.
Refer to the appropriate section of the user manual.
WARNING
CARBON MONOXIDE POISONING
CAN LEAD TO DEATH
Carbon monoxide poisoning: Early signs of carbon monoxide poisoning
resemble the flu, with headaches, dizziness or nausea. If you have
these signs, the heater may not be working properly. Get fresh air at
once. Have the heater serviced. Some people are more affected by car-
bon monoxide than others. These include pregnant women, people with
heart or lung disease or anemia, those under the influence of alcohol,
and those at high altitudes.

SERVICING
Servicing must be carried out by a qualified gas installer.
Frequency of service depends on usage, but must be carried out at the first sign of
malfunction and at least once in 2 years.
Spiders are the biggest pests, because they tend to occupy the smallest of
holes which will be in the burner venturi or the pilot air holes. If spiders are a prob-
lem in the home, have your fireplace serviced just before the new season begins.
Suggested procedure for servicing:
1. Isolate the gas supply and work on a cold unit.
2. Remove the coals or pebbles.
3. Remove the burner and empty the black radiant ceramic ash into a container.
4. Clean the burner and venturi by vacuuming.
5. Remove the surrounding stone or ceramic ash and clean by vacuuming.
6. Inspect the ODS pilot and clean the airways. Check the spark gap.
7. Inspect and clean the main jet
8. Re-assemble the components.
9. Turn on the gas supply and leak test.
10. Check pilot and burner for good ignition.
11. Light the fire and check pressure settings.
12. Check the safe operation of the unit.
CLEANING
Should soot deposits appear on the stainless mosaic tiles, first clean with a dry
cloth when cold, and follow up with a cloth dampened with methylated spirits and a
final buffing with a dry cloth. Do not use an oil based cleaner, as the oil tends to dis-
colour the tiles when heated.
The surrounding facia may be cleaned with any good stainless steel cleaner,
whilst a damp cloth should clean any other surfaces.
