OPERATING INSTRUCTIONS
INSTALLING THE FIRE
Your CORGI qualified gas engineer should install
the fire in accordance with the following
regulations and standards:The Gas Safety (Installation and Use) Regulations
1998 (as amended).
The Building Regulations for England and Wales
2000 ref; Approved Document J 2002 edition
(issued by the DTLR).
The Building Standards (Scotland) (Consolidation)
Regulations.
BS5440 parts 1 and 2 1990, BS5871 And these
Installation Instructions.
Warning: Failure to comply with the
regulations, requirements, or these instructions
will invalidate the guarantee and could have
hazardous consequences.
Please note that in tight recesses the gas supply
point may be inaccessible. Therefore it may be
necessary to connect the pipe for the gas supply to
the fire before installing the fire into its recess.
FITTING THE FEET
Care should be taken when fitting the feet not to
damage the painted surfaces of the fire.
• The feet (4 off) are positioned in each corner of
the fire base using the washers and screws
provided.
• Tools required: A no. 2 pozidrive screwdriver.
FLUE SYSTEM
The stove must be connected to a suitable and
efficient flue that provides a good updraught to
safely take the products of combustion (fumes)
from the stove outlet to the outside air. To ensure a
good updraught it is important that the flue gases
are kept warm and that the flue size suits the stove.
The termination of the outlet at the top of the flue
also needs to comply with the Building
Regulations. The minimum effective height of the
chimney must be at least 3 metres and when warm
the flue draught should be between 0.05 and 6mb
(0.5mm to 6mm water gauge).
The Bunny requires a minimum flue size of 100mm
(4 inches) and the Becton 7 requires a minimum
flue size of 125mm (5 inches). If the stove is being
connected to a chimney with an internal flue size
greater than 225mm (9 inches) diameter or 200 x
200mm square, a 125mm (5 inches) diameter
stainless steel flexible flue liner complying with BS
715 should be installed in the flue.
If a new chimney is being provided it should fully
comply with the relevant Building Regulation
Requirements and BS 5440: Part 1. Suitable types
of chimney include the following.
• Masonry chimney built with clay or concrete liners, or a chimney block system meeting Building
Regulations.
• Precast concrete gas flue block complying with
BS 1289: Part 1
Factory made metal chimney complying with BS
715 (often called "Twin wall Class 2 chimney") or
Factory made metal insulated chimney complying with BS 4543: Part 2 (often called "Class 1 prefabricated metal chimney"). To ensure the flue
gases are kept warm an insulated chimney system
should be used if the chimney is positioned outside
the building.
The flue must be terminated with a suitable
chimney pot or cowl and the chimney or flue shall
be swept prior to installation unless the chimney is
clean and unobstructed.
The flue and chimney installation must be
carefully checked by a competent person before
fitting the stove to ensure it is suitable and will
work safely. The flue must also pass a Flue flow
test (smoke test) to BS 5440: Part 1.

HEARTH REQUIREMENTS
To comply with current Building Regulations the
fire must stand on a fireproof hearth, which has an
upper fireproof layer of 12mm non-combustible
material. If the rear of the fire is to be pushed up
against a surface it must be of a non-combustible
material.
The hearth must protrude at least 25mm in front of
the glass window and 150mm either side.
The hearth must not be capable of inadvertent
covering by a carpet or rug. This should be
achieved by either:
The hearth being 50mm above the level of the room
floor. A 50mm high fender or kerb being fixed
around the edge of the hearth.
CONNECTING THE GAS SUPPLY
Once the fire is in place it is then possible to
connect the gas supply. The gas supply point is
located at the rear of the appliance and should be
connected in accordance with the following
requirements.
Check that the appliance is suitable for the gas
supply; refer to data labels on packaging and/or the
fire for gas type. Note: Natural gas and Propane
(LPG) models are not interchangeable.
The gas installation must be in accordance with the
current issue of BS6891.Gas supply pressure at the
fire should be 20mbar for natural gas.
The gas supply should be connected with the
1/4"BSP nut and olive with 8mm tubing.
A maximum pipe run of 1.5 meters (or 5 feet)
should be adhered to and copper tubing may be
used provided a distance of 25mm is maintained
between pipe-work and any surface of the fire. A
gas service cock should be fitted adjacent to the
fireplace to enable safe removal of the appliance for
servicing. After fitting the supply, operate the gas
cock (supplied) and check all joints up to the
termination of the supply pipe for gas tightness
using a soap/water solution and the pressure drop
method.
To check the pressure to the burner it is
necessary to ignite the appliance and set to 'high
rate'.
This is carried out by following instructions on
pages 9 and 10.
Cold setting pressures are in the Technical data
section on page 6.
The pressure test point is located through the hole
in the valve bracket marked 'test point',
See Fig.8 below.

FIRE TESTING
Flame failure device testing
Step 1 Ignite the appliance in accordance with
page 9 and run for 60 seconds.
Step 2 Turn the appliance off to extinguish the
pilot, listen for a snap at the control valve. This
should occur within 60 seconds of the pilot flame
being extinguished. The snap sound will be the
magnet disengaging, and thus shutting off the flow
of gas to the pilot and burner.
Spillage Test
A qualified gas engineer should Perform a spillage
test as follows:
Step 1. Close all doors and windows.
Step 2 Light the appliance and set to the high rate.
Step 3. Allow fire to warm up for 10 minutes.
Step 4. Position the smoke match at the back of the
fire centrally beneath the draught diverter as shown
in Fig 9.
All of the smoke should be drawn into the fire.
If this does not occur the appliance must be
disconnected and the flue checked.
Step 5. If there is an extractor fan in any room,
this must be turned on and any doors between it
and the fire left open, repeat the spillage test.
Repeated operation of the spillage monitoring
system indicates that there maybe a flue draw
problem. In this situation no more attempts at
operating the appliance should take place and your
gas engineer should be contacted.
Warning: The spillage monitoring system is a
safety feature required by law and must not be
adjusted or put out of action by the installer. If
the spillage monitoring system or any of its parts
are to be replaced, only original manufacturers
parts are to be used.
Fig. 9
Note: The fire will give off non-toxic fumes when
first used. This is perfectly normal and is due to the
paint curing, it will disappear after the first few
hours. Once the spillage test is complete open
windows and doors to ventilate the area.

DETAIL OF PILOT ASSEMBLY
It is strongly recommended to leave the pilot on
permanently. This will keep the fire and its
components, including the ceramic coal set in a
warmer state and assist ignition to the burner.
This in turn will reduce condensation in the
chimney and any associated flue problems.
The pilot can be viewed through the L/H & centre
front slots in the base matrix.
