Installation

Instructions

READ

THESE

INSTRUCTIONS

CAREFULLY

BEFORE

INSTALLATION

These instructions cover the basic principles to ensure satisfactory installation of the stove and cannot

cover all situations due to the site of location conditions. In allcases the installation must comply with

National and European Building Regulations, Local Authority Byelaws and other specifications or

regulations as they affect the installation of the stove.

Health

and

Safety

Precautions

Handling

Adequate

facilities

must

be

available

for

unloading

and

site

handling.

Fire

Cement

Some

types

of

fire

cement

are

caustic

and

should

not

be

allowed

to

come

into

contact

with

the

skin.

In

case

of

contact,

wash

immediately

with

plenty

of

water.

Metal

Parts

When

installing

or

servicing

the

stove,

take

care

to

avoid

the

possibility

of

personal

injury.

Note:

Any

white

deposits

on

the

stove

joints

are

caused

by

humidity

reacting

with

the

joint

sealant.

These

deposits

may

be

brushed

off

and,

if

necessary,

blackened

with

a

proprietary

stove

polish.

Important

Warning

This

stove

MUST

NOT

be

installed

into

a

chimney

that

is

shared

with

any

other

heating

appliance.

No

purpose

provided

ventilation

is

required

for

stoves

rated

under

5kW.

For

each

kW

above

5kW,

550

mm

2

of

fixed

ventilation

is

required

i.e.

a

stove

rated

at

8kW

would

require

3

x

550

mm

2

=

1650

mm

2

of

fixed

ventilation.

If

more

than

one

appliance

is

installed

in

the

same

room,

the

ventilation

requirements

for

each

appliance

must

be

added

together.

There

MUST

NOT

be

an

extractor

fan

fitted

in

the

same

room

as

the

stove

as

this

can

cause

the

stove

to

emit

fumes

into

the

room.

Installation

Chimney

The

chimney

must

be

fitted

in

accordance

with

manufacturer’s

instructions

and

the

relevant

part

of

the

Building

Regulations.

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

125mm

and

not

more

than

200mm.

If

any

of

these

requirements

are

not

met,

the

chimney

should

be

lined

by

a

suitable

method.

The

chimney

must

be

swept

before

connection

to

the

stove.

Where

the

chimney

is

believed

to

have

previously

served

as

an

open

fire

installation,

it

is

possible

that

the

higher

flue

gas

temperature

from

the

stove

may

loosen

deposits

that

were

previously

securely

in

place,

with

the

possible

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

a

local

installer.

AMIC/12/ST/PW/1

Flue

Draught

A

flue

draught

of

minimum

1.2mm

to

a

maximum

2.5mm

water

gauge

is

required

for

satisfactory

appliance

performance.

The

flue

draught

should

be

checked

under

fire

at

high

output

and,

if

it

exceeds

the

recommended

maximum,

a

draught

stabiliser

must

be

fitted

so

that

the

rate

of

burning

can

be

controlled

and

to

prevent

over

firing.

Connection

to

the

Chimney

An

existing

fireplace

opening

can

be

bricked

up

or

sealed

with

a

register

plate.

A

short

length

of

flue

pipe

of

a

minimum

125mm

internal

diameter

may

then

be

used

to

connect

the

stove

to

the

chimney.

This

flue

pipe

should

conform

to

Building

Regulations.

Ensure

that

the

pipe

end

is

no

closer

than

76mm

to

the

side

or

rear

chimney

walls.

Ideally,

the

old

fireplace

should

be

filled

in

so

that

there

is

a

smooth

streamlined

entry

into

the

flueway.

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.

This

appliance

is

not

suitable

for

installation

in

a

shared

flue

system.

Both

the

chimney

and

flue

pipe

must

be

accessible

for

cleaning

and

if

any

parts

of

the

chimney

cannot

be

reached

through

the

stove

(with

baffle

removed),

a

soot

door

must

be

fitted

in

a

suitable

position

to

enable

this

to

be

done.

Material

Clearances

A

MINIMUM

clearance

to

combustible

material

MUST

be

at

least

1500mm.

The

stove

can

be

recessed

in

a

suitable

sized

fireplace

but

a

permanent

free

air

Operating

Instructions

These

stoves

have

been

designed

to

burn

clean

and

efficiently

only

when

operated

correctly

following

the

manufacturer’s

guidance

given

in

this

manual.

WARNING

These

appliances

will

be

HOT

when

in

operation

and

due

care

should

be

taken

when

operating

the

controls.

Air

Controls

It

is

essential

for

the

stove

to

have

an

adequate

air

supply

for

combustion

and

ventilation.

The

primary

and

secondary

air

inlets

must

be

kept

clear

from

obstruction.

Primary

Air

Primary

air

is

controlled

via

the

two

rotary

air

controls

on

the

bottom

of

the

door.

This

provides

a

conventional

air

draught

to

the

bed

of

the

fire.

The

primary

air

intakes

can

be

adjusted

to

give

the

best

possible

results

when

burning

different

fuels.

Secondary

Air

The

cast

iron

stove

is

fitted

with

an

“air

wash”

system.

This

secondary

air

supply

to

the

stove

is

controlled

through

a

slider

assembly

located

at

the

top

of

the

stove.

Note:

The

secondary

air

control

is

open

when

pushed

to

the

right.

Closed

Open

Multi-fuel

Grate

There

are

two

types

of

multi-fuel

grates

for

these

stoves,

Rotary

style

and

grid

style.

For

the

rotary

style

grate,

you

can

operate

it

by

dragging

the

stainless

steel

rod

forward

and

backward.

For

grid

style

grate,

a

special

hook

is

supplied

to

de-ash.

It

is

important

to

de-ash

regularly,

to

ensure

that

the

primary

airflow is not impeded, as a build-up of ash can damage the cast iron bed.

Ashpan

It

is

essential

that

you

empty

the

ashpan

regularly.

Use

the

supplied

tool

to

lift

the

ashpan

out

of

the

stove.

IMPORTANT

-

It

is

very

important

to

empty

the

ashpan

regularly.

If

the

ash

is

allowed

to

build

up

on

the

underside

of

the

grate

then

burnout

or

distortion

of

the

grate

may

be

caused

7 Ref:

On

Solid

Mineral

Fuels

DO

NOT

have

more

than

a

30

degree

incline

of

the

fuel

bed

from

front

to

back,

when

you

put

solid

mineral

fuels

on

the

fuel

bed.

The

height

of

loading

fuels

must

not

exceed

the

rear

cast

iron

lining.

The

refuelling

intervals

at

nominal

heat

output

will

be

approximately

every

4

hours.

When

using

solid

mineral

fuels,

we

suggest

you

keep

the

secondary

air

control

in

the

closed

position,

so

it

can

burn

at

maximum

efficiency.

This

allows

the

primary

air

controls

to

be

adjusted

to

set

the

burn

rate

of

the

appliance.

In

order

to

prevent

the

ash

from

being

stacked

to

the

underside

of

the

bottom

grate,

always

de-ash

before

refuelling.

Once

the

ash

builds

up,

it

can

easily

stifle

the

airflow

and

causes

the

fire

to

die.

On

Wood

burning

With

a

full

load

of

wood,

the

stove

will

need

to

be

refuelled

approximately

every

1.5

hours.

Wood

can

be

stacked

higher

in

the

stove

than

solid

mineral

fuel

but

care

must

be

taken

that

logs

do

not

touch

the

baffle.

Wood

burns

most

efficiently

with

the

primary

air

controls

closed

and

the

secondary

control

partially

open.

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

best

with

a

layer

of

ash

on

the

fuel

bed

and

it

is

therefore

only

necessary

to

remove

surplus

ash

from

the

stove

occasionally.

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

tar

deposits

in

the

stove

and

chimney

and

will

not

produce

a

satisfactory

heat

output.

Lighting

the

Stove

It

is

recommended

to

get

the

best

out

of

the

appliance

that

you

start

with

two

or

three

small

fires

before

you

operate

your

stove

to

its

maximum

heat

output.

This

is

to

allow

the

paint

to

cure

equally

around

its

surface

and

to

give

a

long

service

life

for

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.

First,

load

the

fire

with

starting

fuel,

i.e.

paper,

dry

sticks

and/or

firelighters

in

the

mode

chosen,

either

wood

or

solid

mineral

fuel.

DO

NOT

USE

liquid/lighter

fuels

to

start

this

appliance.

Light

the

fire

at

the

base

leaving

all

air

controls

open.

Allow

the

fuel

to

reach

a

steady

glow

and

build

the

fire

up

gradually.

Once

you

have

a

good

fire

established

across

the

grate

bed,

further

fuel

can

be

added

as

required.

Shutting

Down

In

order

to

shut

down

the

stove,

close

the

primary

air

controls,

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

go

out.

If

you

want

to

revive

the

fire

it

is

recommended

that

the

primary

air

control

is

opened

first,

then

open

the

secondary

air

slider.

WARNING
