Preliminary Installation Procedures for
WAGENER Fairburn Cooker
To get the full benefit from the Wagener Fairburn it is important that it is installed correctly, both for
efficiency and safety sake. The following points should be noted:
1.
The characteristics and purpose of the Wagener Fairburn will determine its position within the home.
Generally an interior wall installation suits flue requirements better than against an exterior wall.
2.
Check for flue obstructions above the ceiling. (header tanks, electrical mains or load bearing roof
supports and the like).
3.
The
recommended vertical flue height for optimum operation is 4.8 meters
as the
performance of the Fairburn depends more on the flue than on any other single component.
It is the draw on the flue that drives the cooker.
4.
Remember a permit is required from your Local Authority.
Assembling the Wagener Fairburn
The Wagener Fairburn chassis will arrive fully assembled and ready to be installed.
(Drawer base, upstand/splashback and plate rack are packaged separately if supplied)
If you choose to lighten the chassis weight for installation you can remove doors, bricks, grates, hot plates etc
but please ensure you have a record of correct placement for refitting as safety and performance may be
affected. We suggest taking photographs and also referring to Wagener Fairburn parts on our website.
Note: the grate is fitted with the wider gap between rungs facing downwards.
Incorrect fitting may cause the grate to buckle and bow.
Floor Protector/Hearth Requirements & Positioning
The Wagener Fairburn requires an ash hearth floor protector only
.
The Ash Hearth floor protector shall have an upper surface, including grouting if required, of a durable,
non combustible material. (eg Tiles, slate, treadle plate etc)
All joints in the surface must be sealed to protect and prevent ash or spilled embers reaching the floor.
Floor protection shall extend under the cooker and not less than the width of the cooker and shall extend
forward 300mm and be 200mm from the side of the firebox door opening (120mm from side of end panel)
For concrete floors trim back any floor coverings to no less than the minimum hearth requirement.
THE WAGENER FAIRBURN
MUST BE AFFIXED TO THE HEARTH AND FLOOR FOR SEISMIC RESTRAINT.
For Seismic Restraint use two holes in the base of the legs and screw through the hearth and into the floor or
for the drawer base model fix through the base beneath the drawer.
Wet Back Fitting
Wagener Fairburn Cookers can be fitted with a wet back. We recommend that you use the “Lion” Wet Back
which has been designed and tested specifically for the Fairburn. In general, wet backs are factory fitted at the
time of ordering. However, a suitably qualified person can fit or change the wet back out in the field if this is
required. Water MUST always be present in the wet back. Tempering valves are required.
The 5.5kw steel boiler requires rust inhibitor in the water and will therefore require an indirect system.
Wetbacks MUST be connected by a Registered Plumber to an open vented system.
Please check the PH level of the water supply
particularly if the area is prone to lime deposits or if the
customer is not on town supply as wet backs can become fouled with lime or affected by corrosion which will
void the warranty.
Please advise the householders NOT to boil the wet back as this will cause vibrations and will
fatigue the wet back, the pipes and the cylinder. This will NOT be covered by the warranty.

Preliminary Installation Procedure
To get full benefit from the Wagener Fairburn it is important that it is installed correctly, both for efficiency
and safety sake. The following points should be noted:-
1. The characteristics of the Wagener Fairburn will determine its position within the home. As a general
rule an interior wall installation suits flue requirements better than against an exterior wall.
2. Check for flue obstructions above the ceiling. (e.g. header tanks, electrical mains or load bearing roof
supports).
3. The minimum vertical flue height for satisfactory operation is 3.7metres above the top of the Fairburn
Flue Flange or 4.6metres above the top of the Floor Protector. Where possible we recommend
4.8metres of flue as the performance of the Fairburn depends more on the flue than on any other
single component. It is the draw on the flue that drives the Fairburn.
4. Remember a permit is required from your Local Authority.
Assembling the Wagener Fairburn
Your Wagener Fairburn will arrive fully assembled and ready to be installed. However, due to the weight of
the fully assembled Wagener Fairburn it is not uncommon for the installer to remove doors, bricks, grates,
cooktop plates, etc. in order to lighten the load when carrying the Wagener Fairburn into the home. When
removing parts care should be taken to remember each part’s exact placement for refitting as safety and
performance may be affected.
Note: The grate fits with the flat face upwards.
Floor Protector/Hearth Requirements & Positioning
The MINIMUM requirement for the Wagener Fairburn is an ASH HEARTH only.
The Floor Protector shall extend under the appliance and NOT Less than the width of the Appliance and shall
extend 300mm forward and 200mm each side of the Fuel Loading/Ash-Removal opening.
The Ash Hearth shall have an upper surface, including grouting, of durable, non-combustible material.
All joints in the surface must be sealed to protect and prevent ash or spilled embers reaching the floor.
For concrete floors trim any floor coverings to the same minimum hearth requirement.
NOTE: THE WAGENER FAIRBURN MUST BE AFFIXED TO THE HEARTH AND FLOOR FOR SEISMIC RESTRAINT.
For Seismic Restraint use two holes in the base of the legs and screw through the hearth and into the floor or
for the drawer base model fix through the base beneath the drawer.
Wet Back Fitting
All Fairburn Cookers can be fitted with a wet back.
We recommend that you use the “Lion” Wet Back which has been designed and tested for the Wagener
Fairburn. In general, wet backs are factory fitted at the time of ordering.
However, a suitably qualified person can fit or change the wet back out in the field if this is required.
The Wagener Fairburn will accommodate 3 different sizes of wet back – see dimension specifications.
Household requirements will determine which size is fitted. Water must always be present in the wet back.
The wet back MUST be connected by a Registered Plumber to an open vented system.
Tempering valves are required.
Please check the PH level of the water supply particularly if the area is prone to lime deposits
or if the customer is not on a town supply as wet backs can over time become fouled with lime
or affected by corrosion which will void the warranty.
Please note that the 5.5kw steel boiler will
require a rust inhibitor in the water. Therefore, unlike wet back systems, indirect heating for domestic hot
water will need to be provided. PLEASE consult with your Plumber/Installer or Wagener Stoves if you require
further advice in this area
.
Please advise the householders NOT to boil the wet back as this will cause vibrations and will
fatigue the wet back, the pipes and the cylinder. This will NOT be covered by the warranty.
OPERATING YOUR WAGENER FAIRBURN
Fuel
Dry, seasoned wood should be used at all times and, as a general rule, the harder the wood the longer it will
burn. Try to buy wood well in advance and store so that the air can circulate through the pile to assist drying.
Wet, unseasoned wood (under 12 months old) can cause creosote problems, especially if the Fairburn is
burned slowly. If unseasoned fuel is used, special care should be taken to ensure that the fire is actually
burning and not just smouldering which will precipitate a creosote problem.
DO NOT burn driftwood or treated timber as they will damage your Fairburn and flue and void your
warranty.
NOTE: The heat output level of the Fairburn is controlled not only by the air control but also by the type and
quality of fuel in the firebox.
COAL may be used in the Fairburn but does tend to be more corrosive and therefore may shorten the life of
the firebox. If you wish to use coal we suggest you burn a mix of wood and coal.
First Burn on a New Appliance or Repainted Appliance
On INITIAL LIGHTING, the high temperature paint used on the Fairburn will give off smoke and odour for
a short period. This is a temporary condition. Open doors and windows to give adequate ventilation
(please
see additional sheet on paint supplied with these instructions).
To condition the firebricks your first 2-3 fires
must be small.
Start Up
1. Rotate the air control (black round plate beneath the firebox door glass) to the open position so that
the widest air opening is obtained.
Caution: refer Over firing section page 6
Position the flue control clockwise towards the (east/west position) so the fire gases
go directly up the flue.
2. Open the firebox door. Ensure ash pan is fitted right back under the grate. Remove cooking plate
above firebox using tool provided. Place crumpled newspaper on top of the grate (if using firelighters
place firelighters under the newspaper). Stack kindling around it like an Indian Tepee, refit cooking
plate, check the flue control is fully open from step 1, light newspaper (or firelighters) through firebox
door, then close firebox door. Once the kindling is well alight add slightly larger pieces of wood
through the top cooking plate until you have a good healthy fire.
3. Refuel once the fire is established.
4. Adjust the air control to the desired setting.
5. It should not be necessary to fill the firebox to capacity. Smaller loads of wood burned on half air
supply will produce more heat per kg of wood. Flue length and outside wind may affect the
performance of the fire.
6. Over Firing will damage your cooker & flue system and will void your warranty.
Please refer to page 6 - Signs of Over Firing, Causes and Remedies.
