GENERAL INSTRUCTIONS AND SAFETY NOTES
Thank you for purchasing your new CHAD-O-CHEF Gas Fireplace manufactured
to high standards and tested for compliance with SANS 1539:2017
The manufacturer and /or its agents and distributors will not be held
responsible for injuries or damages caused by faulty or incorrect installation or
use of the appliance.
1. This replace provides radiant heat both eciently and safely, using the latest
technology, without the need of a ue. This appliance consumes oxygen
when in use and it is important that it is only used in a well ventilated area,
for the ecient performance of the appliance and for the safety of the
occupants of the area.
2. No permanent ventilation is required if the room is 57m³ or larger, but an
opening window is required. Should the room size be smaller than 57m³
then permanent ventilation will be required. This volume may include up to
50% of adjacent rooms connected by permanent archways, but not rooms
separated by a closable door.
3. DO NOT install in a bathroom.
4. DO NOT install in a bedroom.
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 paran appliances must
be included in the calculations. It is the installer’s responsibility to do these
calculations on behalf of the home owner.
6. This appliance may only be installed by a registered Natural Gas installer
and must comply with the installation 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 installation, the installer is required to explain the
operational details of the appliance together with the safety instructions. You
will be asked to sign acceptance of the installation and be provided with a
completion certicate. You should only sign for acceptance 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 light-up of your new replace, the “newness” will burn o within the
rst 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 ventilated with all windows open during this period.
8. Humidity levels will rise with the use of your replace, 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.

to be cut into the masonry construction housing the unit
(2x brick-sized holes). - see diagram on pg.6
Choosing a site:
This replace may be installed in any room in a home except in bedrooms or
bathrooms where the humidity levels are too high. (See page 1)
Avoid areas where there are strong draughts, which may be generated by
outside doors. It is recommend that the replace should not be installed
within 500mm of any air vent, as this could aect the working of the ODS.
This replace is to be installed in an island setting, as it is not suitable to
be installed against a wall.
Clearances to combustible materials:
Combustible materials are dened as wood, fabrics, or other materials likely
to burn when exposed to ame. Any other material which is likely to discolour,
melt, or lose shape when exposed to moderate heat, should fall into the
same category.

INSTALLATION INSTRUCTIONS
FOR QUALIFIED GAS INSTALLER
A masonry shelf may be tted 800mm above the replace but under no
circumstances should any electrical equipment such as a TV be positioned
above. Any ornaments positioned above the replace must be able to
withstand the elevated temperatures and moisture. No combustible
materials whatsoever must be used or placed
above the replace.
Unpacking
Carefully undo the strapping to separate loose parts and remove all plastic
protective sheeting.
Positioning and Sizing
Conrm 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 replace into, so that it rests on the surrounding rim.
Provide a vent for the primary air to the burner by means of 2x brick-size
holes, leading into the cavity below the unit.
Connect up according to SANS 10087-1
Connect a copper pipe from the gas supply via a regulator, complying with
SANS 1237, to the Ø8 compression tting on the control valve, taking into
account the distance from the gas supply, to calculate the size of the copper
pipe.
Setting up
1. Insert the burner with the venturi facing the gas jet, and ensure the burner is
seated correctly.
2. Fill the burner with the special glass pebbles. Use only the number of
pebbles 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.
Brieng the customer
All instructions must be handed over to the user for safekeeping. Instruct the
customer how to turn the gas on and o and how to light and control the re.
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 rst sign of malfunction and at least
once in 2 years.

NG6801 VALVE: OPERATING INSTRUCTIONS
NG6801 VALVE: PRESSURE TESTING
The ODS pilot is situated on the side of the burner.
The gas control valve is accessible by removing the side cover, which lifts o.
1. Push in and turn the control knob to the pilot position and hold it there for a
few seconds to allow the gas to feed to the pilot.
2. Continue turning anti-clockwise through the PILOT to click at the SPARK
position. Ensure that the pilot is lit. If not,
return to OFF position and repeat.
3. When the pilot is lit, keep the knob
depressed for approximately 10 to 15
seconds.
4. Now release the knob and the pilot should
stay alight.
If the pilot is extinguished during use, wait
3 minutes before repeating the ignition
procedure.
5. Continue turning the knob anticlockwise
to the HIGH position and the main burner should light after a few seconds
6. Select the required HIGH or LOW setting.
7. To turn the re OFF, depress the knob and turn it clockwise to the OFF
position and release. This will extinguish both the main burner and the pilot
burner.
iNlET prEssurE

1. Access the valve by lifting the replace out of its masonry construction.
2. Attach inline “Pressure Test Tee” into main inlet line.
3. Adjust line pressure to correct working pressure, whilst re is set on high.
The pressure should be according to the
data set out in the SPECIFICATIONS. The
replace is factory set to work at these
pressures and any signicant variation could
indicate a supply problem.
If the pressure is too high or too low, then
check the inlet pressure, by the above
procedure.

conform. Refer to the latest SANS 1539:2017 Annex A ,C & E
Check there is gas in the gas bottle (if bottle is nearing empty change over to
new bottle)
Check that the inlet running pressure is 2.1 kPa (whilst running). If not correct:
Check that the supply pipe is the correct diameter for the distance
covered.
Check that the regulator is functioning correctly.
The burner must be correctly positioned and sitting ush on the bottom
plate,
Jet is centrally aligned with the burner venturi.
Check for spider webs in the venturi.
The Glass pebbles supplied with Chad-O-Chef replaces must be inside the
burner. Ensure that the right amount of glass pebbles placed on the replace
are correct, as supplied by Chad-O-Chef.
DO NOT use more glass pebbles than recommended and supplied. (See
Page 2)
The room must be bigger than the
minimum room size for that replace.
(See Page 2)
Ensure that there is adequate ventilation in the box housing the unit. (See
Page 1)
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 eciently 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 o immediately and
relight after 1 min. If condition persists, contact your gas installer.
Should a leak in the gas be detected, turn o the gas at the gas cylinder, and
contact your installer immediately.
Should there be an unexplained shutdown, which could be the result of
insucient oxygen in the room, shut o the gas supply, then open windows
and doors in the room, wait 5 min before attempting to restart. If condition
persists, contact your gas installer.

WARNINGS
WARNING
This is an un-vented gas heater. It uses air (oxygen) from the room in
which it is installed. Provisions for adequate ventilation must be provided.
Refer to appropraite section of the user manual.
WARNING
This appliance shall not be installed in bedrooms or bathrooms.
WARNING
CARBON MONOXIDE POISONING
CAN LEAD TO DEATH
Carbon monoxide poisoning: Early signs of carbon monoxide poisoning
resemble the u, 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 aected by carbon monoxide
than others. these include pregnant women, people with heart or lung
disease or anemia, those under the inuence of alcohol, and those at high
altitudes.

CLEANING
SERVICING
Should soot deposits appear on the stainless steel, rst clean with a dry cloth
when cold, and follow up with a cloth dampened with methylated spirits and a
nal bung with a dry cloth. Do not use an oil based cleaner, as the oil tends to
discolour the stainless steel when heated.
The surrounding facia may be cleaned with any good stainless steel cleaner,
whilst a damp cloth should clean any other surfaces.
Servicing must be carried out by a qualied gas installer.
Frequency of service depends on usage, but must be carried out at the rst 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 problem in
the home, have your replace 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 glass pebbles inside into a temporary container.
3. Clean the burner and venturi by vacuuming.
4. Inspect the ODS pilot and clean the airways. Check the spark gap.
5. Inspect and clean the main jet
6. Re-assemble the components.
7. Turn on the gas supply and leak test.
8. Check pilot and burner for good ignition.
9. Light the re and check pressure settings.
10. Check the safe operation of the unit.

GUARANTEE CLAIM FORM
Guarantee Claim Form
The Guarantee given by Chad-O-Engineering (Pty) Ltd covers the working
components, on all Chad-O-Chef Gas Fireplaces for the period of 2 Years
(+ 1 Year t’s & c’s apply), covering manufacturing defects caused in the
manufacturing process. This does not cover component malfunction if the
product is not installed by a registered Gas Installer, or the product is
modified after leaving the factory.
Chad-O-Engineering (Pty) Ltd will not be held responsible in the event of
rust. Stainless Steel is inherently corrosion resistant when compared to
other metals, due to its thin protective surface layer. This does not mean
that it is rust-proof & it will require regular maintenance to preserve this
protective surface layer in order to enjoy the high-quality standard that is
to be expected from Chad-O-Chef.
Read your complete Instruction manual & ensure that you understand it
fully. If you have any concerns, please contact our service department for
