1. SAFETY AND UNPACKING
Installer
Before continuing any further with the installation of this appliance please read the
following guide to manual handling.
The approximate lifting weight of this heat engine and convection box is 7.4 kg.
One person should be sufficient to lift the heat engine and convection box. If for
any reason this weight is considered too heavy then obtain assistance.
When lifting always keep your back straight. Bend your legs and not your back.
Avoid twisting at the waist. It is better to reposition your feet.
Avoid upper body/top heavy bending. Do not lean forward or sideways whilst
handling the fire.
Always grip with the palm of the hand. Do not use the tips of fingers for support.
Always keep the fire as close to the body as possible. This will minimise the
cantilever action.
Use gloves to provide additional grip.
Always use assistance if required.
This product uses fuel effect pieces and a burner compartment rear wall
containing Refractory Ceramic Fibres (RCF), which are man-made vitreous
silicate fibres. Excessive exposure to these materials may cause irritation to
eyes, skin and respiratory tract. Consequently, it is important to take care when
handling these articles to ensure that the release of dust is kept to a minimum.
To ensure that the release of fibres from these RCF articles is kept to a
minimum, during installation and servicing we recommend that you use a HEPA
filtered vacuum to remove any dust and soot accumulated in and around the
fire before and after working on the fire. When replacing these articles we
recommend that the replaced items are not broken up, but are sealed within a
heavy duty polythene bag, clearly labelled as RCF waste. RCF waste is classed
as a stable, non-reactive hazardous waste and may be disposed at a landfill
licenced to accept such waste. Protective clothing is not required when
handling these articles, but we recommend the use of suitable gloves to
prevent irritation. We also recommend you follow the normal hygiene rules of
not smoking, eating or drinking in the work area and always wash your hands
before eating or drinking.
This appliance does not contain any component manufactured from asbestos
or asbestos related products.

2.2 Efficiency.
The efficiency of this appliance has been measured as specified in BS 7977 - 1 and
the result is as below:
Model Efficiency % (Gross) Efficiency % (Net)
955 55 61
955 when converted to LPG. 58 63
The gross calorific value of the fuel has been used for this efficiency calculation. The
test data from which it has been calculated has been certified by Advantica
Certification services (0087). The efficiency value may be used in the UK
Government's Standard Assessment Procedure (SAP) for energy rating of dwellings.
The conversion of net efficiency to gross was achieved by multiplying the net
efficiency by the following conversion factor from Table E3 of SAP 2005, rounding
down to the nearest whole number.
