MISSION

WARNING NOTE

Properly installed, operated and maintained, this appliance will not emit fumes into the dwelling. Occasional fumes from de-ashing and refuelling may occur. However, persistent fume emission is potentially dangerous and must not be tolerated.

If fume emission does persist, then the following immediate action should be taken: -



Open doors and windows to ventilate the room and then leave the premises.



Let the fire go out.



Check for flue or chimney blockage and clean if required.



Do not attempt to re-light the fire until the cause of the fume emission has been identified and corrected. If necessary, seek expert advice.

The most common cause of fume emission is flueway or chimney blockage. For your own safety these must be kept clean at all times.

A

DVERSE

W

EATHER

In a small number of installations, occasional local weather conditions (e.g. wind from a particular direction) may cause downdraught in the flue and cause the stove to emit fumes.

In these circumstances, the stove should not be used. A professional flue installer will be able to

JINHCR03 RevB 22/06/2012

advise on solutions to this problem (e.g. antidowndraught cowl).

Do not fit an extractor fan in the same room as this appliance.

Installation

Instructions

C

HIMNEY

The chimney height and the position of the chimney terminal should conform to Building

Regulations.

Check that the chimney is in good condition, dry, free from cracks and obstructions.

The diameter of the flue should not be less than

150mm and not more than 200mm.

If any of these requirements are not met, the chimney should be lined by a suitable method.

If there is no existing chimney then either a prefabricated block chimney in accordance with

Building Regulations Approved Document J, or a twin-walled insulated stainless steel flue to BS

EN 1856 can be used. These chimneys must be fitted in accordance with the manufacturer’s instructions and Building Regulations.

If the chimney is believed to have previously served an open fire installation, it is possible that the higher flue gas temperature from the stove may loosen deposits that were previously firmly adhered, with the consequent risk of flue blockage. It is therefore recommended that the chimney be swept a second time within a month of regular use after installation.

If you have any doubts about the suitability of your chimney, consult your local dealer/stockist.

C

ONNECTION TO THE

C

HIMNEY

The chimney must be swept before connection to the stove.

An existing fireplace opening can be bricked up or sealed with a register plate.

A short length of flue pipe of minimum 125mm internal diameter may then be used to connect the stove to the chimney. This flue pipe should be made of 316 grade stainless steel or vitreous enamelled steel, nominal thickness 1.2mm.

Ensure that the pipe end is no closer than

76mm to the chimney walls.

The length of any horizontal run of flue pipe must not exceed 125mm.

It is essential that all connections between the stove and chimney-flue are sealed and made airtight.

Both the chimney and flue pipe must be accessible for cleaning and if ANY part of the chimney cannot be reached through the stove

(with baffle removed), a soot door must be fitted in a suitable position.

F

LUE

D

RAUGHT

If the draught exceeds the recommended maximum, a draught stabiliser must be fitted so that the rate of burning can be controlled and to prevent over firing.

If the reading is less than the recommended minimum then the performance of the appliance will be compromised.

The flue draught should be checked under fire at high output.

Minimum Draught – 1.2mm Water Gauge

Maximum Draught – 2.5mm Water Gauge

LEARANCES

Your stove must be installed on a floor with adequate load-bearing capacity, otherwise suitable measures should be taken.

Use the adjusting screws in the feet to level the stove.

The stove can be recessed into a suitably sized fireplace. Ensure there is a free air gap of at least 150mm above and 50mm around the sides and rear of the stove.

Where possible it is recommended that a free air gap of 150mm or more is left around the sides of the stove to obtain maximum heat output and to gain access to the rear of the stove.

The hearth should extend at least 225 mm from the front of the stove.

If the stove is to stand in an appliance recess, it should stand wholly above a solid, noncombustible hearth, at least 125 mm thick (this may include the thickness of a solid floor).

If the stove is not to stand in an appliance recess, it may stand wholly above a hearth

JINHCR03 RevB 22/06/2012 made of non-combustible board / sheet material or tiles, at least 12mm thick.

The hearth should extend at least 150 mm from the sides and rear of the stove, and at least 225 mm from the front of the stove.

All non-combustible walls closer than 300mm to the stove should be at least 75mm thick.

OMMISSIONING

& H

ANDOVER

Upon completion of the installation, allow a suitable period of time for any fire cement and mortar to dry out.

A small fire may then be lit and checked to ensure the smoke and fumes are taken from the

stove up the chimney and emitted safely to atmosphere.

Do not run the stove at full output for at least

24 hours.

On completion of the installation and commissioning, ensure that the operating instructions and operating tools for the stove are left with the customer.

Advise the customer on the correct use of the appliance with the fuels likely to be used on the stove and warn them to use only the recommended fuels for the stove.

Advise the user on what to do should smoke or fumes be emitted from the stove.

The user should be warned to use a fireguard to

BS 8423 in the presence of children and/or infirm persons.

ONTROLS

This stove has been designed to burn far more efficiently than a traditional stove, with the obvious notable feature of clean glass.

However, for this product to work properly it must be used correctly. To prevent excess smoke emissions, the air controls of this appliance must only be operated as directed in the instructions.

It is essential that the stove has an adequate air supply for combustion and ventilation.

IR

Tertiary air aids in good secondary combustion of the fuel and reducing emissions into the chimney and environment.

Tertiary air can be controlled by adjusting the cover plate on the back of the stove.

Warning! - This appliance will be hot when in operation and due care should be taken.

JINHCR03 RevB 22/06/2012

We advise that suitable gloves are used when operating the Primary and Secondary air controls, and when opening the door.

R

IDDLING

G

RATE

Your Hunter Stove is fitted with a locomotive type grate. So that de-ashing can be carried out cleanly and easily, it is riddled from the outside of the stove with the doors closed.

To burn wood, push the operating tool up and away from you.

When left in this position, air is restricted through the bed of the fire providing a solid base to build up a bed of ash.

Surplus ash can be removed either by gentle riddling or with a shovel.

It might prove beneficial when burning more reactive fuels to leave the grate in a “neutral” position, thus directing some under fire air and some over fire air to the firebed.

N

OTES ON

W

OOD BURNING

With a full load of wood, the stove will need to be refuelled approximately once every hour.

Wood can be stacked in the stove, but care must be taken that logs do not touch the baffle.

JINHCR03 RevB 22/06/2012

Overloading the stove can cause excess smoke to be emitted.

Wood burns most efficiently with the secondary air valve lever in the open position and the primary control closed. Moving the secondary control will control the burn rate of the stove.

Note - primary and secondary air is needed to light the stove, see section entitled ‘Lighting the

Stove’

Wood burns most efficiently on a bed of ash and it is therefore only necessary to remove surplus ash from the stove occasionally.

If there is insufficient burning material in the firebed to light a new fuel charge, excessive smoke emission can occur.

Refuelling must be carried out with a sufficient quantity of glowing embers and ash, so that the new fuel charge will ignite quickly. If there are too few embers, add some kindling to prevent excessive smoke.

L

IGHTING THE

S

TOVE

We recommend that you have two or three small fires before you operate your stove to its maximum heat output.

This is to allow the paint to cure in steadily and to give a long service life of the paint finish.

During this curing in process you may notice an unpleasant smell. It is non-toxic, but for your comfort we would suggest that during this period you leave all doors and windows open.

To light the stove open the primary and secondary air controls fully. Light one or two firelighters placed centrally on the grate, allowing the flames to become established before placing several pieces of small dry

kindling in a criss-cross fashion above the firelighters, taking care not to smother the fire.

Close the stove door. Once the kindling is well alight open the door and build the fire by gradually adding slightly larger pieces of wood, closing the door afterwards.

Once you have a good fire established across the grate bed, further fuel can be added as required and the air controls set to the correct position (see ‘Notes on Wood burning’).

Should the fire fail to light correctly open the door and use a poker to spread the fuel across the grate. Close the door and allow the fuel and stove to cool before attempting to relight the fire.

N.B. Leaving the air controls in the closed position, adding too much fuel or using wood that is wet or too large will prevent the fire from establishing correctly and may result in smoke emission from the stove.

R

EDUCED

C

OMBUSTION

In order to shut down the stove, close the primary control, then close the secondary air slider by moving the handle all the way to the left.

If the controls are left in this position, the fire will be starved of air and will die down.

If you want to revive the fire it is recommended that the primary air control is open first, and then open the secondary air slider.

Warning!- The stove will remain hot for a considerable time after the fire has been extinguished.

R

ECOMMENDED

F

UELS

Hunter Stoves recommend that wood logs are burnt in this appliance.

Burn only dry, well-seasoned wood, which should have been cut, split and stacked for at least 12 months, with free air movement around the sides of the stack to enable it to dry out.

Burning wet or unseasoned wood will create excess smoke emissions, tar deposits in the stove and chimney and will not produce a satisfactory heat output.

Only authorised smokeless fuels may be used in smoke control areas.

Warning! - Petroleum coke fuels or household waste must not be burnt on this appliance.

This appliance should not be used as an incinerator.

No liquid fuels should be burnt on this appliance.

C

HIMNEY AND

F

LUEWAYS

It is important that the chimney, flueways and any connecting flue pipe are swept regularly.

This means at least once a year for smokeless fuels and at least twice a year for wood and other fuels.

The baffle will need to be removed from its supports in order to sweep the chimney (see assembly instructions).

JINHCR03 RevB 22/06/2012

Only wire-centred sweeps’ brushes fitted with a guide wheel should be used.

If it is not possible to sweep all parts of the chimney through the appliance, ensure there is adequate access to cleaning doors.

P

ERIODS OF PROLONGED NON

-

USE

If the stove is to be left unused for a prolonged period of time then it should be given a thorough clean to remove ash and unburned fuel residues. To enable a good flow of air through the appliance to reduce condensation and subsequent damage, leave the air controls fully open

If the appliance has been unused for a long period of time, such as during the spring and summer months, a competent person should check the chimney for potential obstructions before lighting the stove.

G

ASKETS

All gasket used on this appliance are produced from a heat resistant material called Manniglas.

The glass gasket will have to be replaced when a new piece of glass is fitted as the gaskets become brittle after firing the stove.

Over time you may also find that the gasket changes colour. This is due to a reduction in the pigment used in the manufacture of the product and no cause for concern.
