PRELIMINARY INSTALLATION PROCEDURES
FOR THE BUTLER MULTI

To get full benefit from the Butler Multi 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 Butler Multi 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 4.2metres above the top of the

Butler Multi Flue Flange. The performance of the Butler Multi depends more on the flue than on any

other single component. It is the draw on the flue that drives the stove.

4. Remember a permit is required from your Local Authority.

Floor Protector/Hearth Requirements

The MINIMUM requirement for the Butler Multi with a wet back fitted or as a DRY model 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 BUTLER MULTI MUST BE AFFIXED TO THE HEARTH AND FLOOR FOR SEISMIC RESTRAINT.

For Seismic Restraint use two holes in the base at the rear and screw through the hearth and into the floor.

NOTE: FOR DRY MODEL AND SPECIAL 2KW WET BACK MODEL PLEASE SEE SEPARATE DRY

INSTALLATION INSTRUCTION SHEET AS CLEARANCES ARE DIFFERENT.

Wet Back Fitting

The Butler Multi is fitted with a wet back unless a Dry Model is requested.( see separate specification sheet )
We recommend that you use the “Lion” Wet Back which has been designed and tested specifically for the
Butler Multi. 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.
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 as wet backs can become fouled with lime which will void
the warranty.
NB Some coals are very corrosive and may shorten the life of the wet back – please check with the
supplier as this is NOT covered by 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.

Baffle & Brick Assembly for Wet Back Model

Position the baffle on the ledge in the top, central chamber of the wet back, in the ceiling of the firebox.
The round rods on the baffle should face downwards. The baffle should then be pushed back so that there is
no gap at the rear. Position the bricks so that they tuck up under the edge of the wet back.
