the ease of use of LP Gas.
Choosing a site:
This replace may be installed in any outdoor area, and is designed to function
correctly with ample ventillation. Avoid areas where there are strong draughts,
which may be generated by narrow passage ways, as excessive wind could
aect the correct working of the repit.
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.
Min clearance to the sides for wood 800 mm
Min clearance to the sides for fabric 1500 mm
Min clearance to the ceiling 1500 mm
Min clearance to a oor ( including carpet ) 300 mm

INSTALLATION INSTRUCTIONS
FOR QUALIFIED GAS INSTALLER
Unpacking
•Carefully undo strapping to separate loose parts and remove all plastic
protective sheeting.
•Conrm that all components for the repit are present, and accounted for.
Positioning and Sizing
Build up a masonry or steel platform to the customers design, with a suitable
space to drop the repit into, so that it rests on the surrounding rim.
Provide ventilation underneath the platform for the primary air to the burner,
by means of a hole, with a minimum size of 100mm².
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 tting 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 Fireglass.
3. Spread the Ceramic Ash or Fireglass evenly around the burner.
NOTE: Should the burner become dislodged, replace it making sure that it
rests at on the lip of the designated platform, without any gaps between it
and the plate.
4. Place Gas Logs in a tee-pee pattern with large hollow centre, or, in a hash(#)
pattern, spread across the burner evenly, allowing for about 50mm gaps
between layers.
Use only the number of Ceramic Ash and Gas Logs, or Fireglass supplied.
Testing and Commissioning
Turn on the gas supply and test for leaks with soapy water.
Ensure that the WORKING PRESSURE is 2,8 kPa at the control valve.
*See checklist for more detail
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.

OUTDOOR FIREPIT: OPERATING INSTRUCTIONS
OUTDOOR FIREPIT VALVE: PRESSURE TESTING
The Outdoor Firepit Valve opens manually to allow gas through to the burner.
1. Open any Shut-O valves in the gas line, leading up to the Control Box.
2. Depress and Turn the ON/OFF VALVE counter-clockwise until rst stop, and
keep the knob depressed.
3. Wait for 5 seconds before depressing the IGNITOR Button, and keep the
ON/OFF knob depressed.
4. If the pilot is extinguished during use, turn OFF the ON/OFF VALVE for 1
minute before repeating the ignition procedure several more times before
consulting your Gas Installer.
5. To turn the Outdoor Firepit Burner OFF, simply turn the main ON/OFF valve
clockwise at the control box to “OFF”.
(This will extinguish both the main burner and the pilot burner.)
1. A “Pressure Test Tee” needs to be
tted in the line just before the main
inlet of the Control Box. (As depicted
below)
2. Adjust line pressure to correct
working pressure, whilst re is set to
“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.

CHECKLIST FOR GAS INSTALLER
CAUTION
Before calling the manufacturer, ensure that all the checkpoints below
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 working pressure is 2.8 kPa. If not correct:
Check that the supply pipe is the correct diameter for the distance
covered.
Check that the regulator is functioning correctly, and not “humming”.
The burner must be correctly positioned and sitting ush on the bottom
plate.
Check that the gas jet is centrally aligned with the burner venturi.
Check for spider webs in the venturi.
The black ceramic ash supplied with the Chad-O-Chef repit must be
placed inside the burner.
Ensure that the number of Gas Logs placed on the repit is correct, as
supplied by Chad-O-Chef.
DO NOT use more Ceramic Ash or Gas Logs than recommended and
supplied. (See Page 3)
Ensure that there is adequate ventilation for the Firepit (See Page 2)
Do not tamper with jets, burners or regulator settings. NEVER MODIFY OR
ADAPT CHAD-O-CHEF PRODUCTS TO WORK DIFFERENTLY.
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.

WARNINGS
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.
WARNING
This Outdoor Firepit must NEVER be installed Indoors

CLEANING
SERVICING
It is normal for soot deposits to appear on the ceramic logs. This phenomenon
adds a rustic aesthetic to your repit and should not be of concern. If the soot
deposits are such that the build-up is excessive, then clean each log individually
with a broom, or brush when cold. Do not use any water or oil based cleaners, as
these will penetrate the ceramic and cause irregular burning of the repit.
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 ceramic logs.
3. Remove the burner and empty the black ceramic ash into a container.
4. Clean the burner and venturi by vacuuming.
5. Inspect the Pilot and clean the airways. Check the spark gap.
6. Inspect and clean the main jet
7. Re-assemble the components.
8. Turn on the gas supply and perform a leak test.
9. Check pilot and burner for good ignition.
10. Light the re and check pressure settings.
11. Check the safe operation of the unit.
