890 HD INSTALLATION INSTRUCTIONS
Prior to installation ensure that the local distribution conditions (identification of the type of gas
and pressure) and adjustment of the appliance are compatible G20 @ 20 mbar.
The front of the fire act as a dress guard, conforming to BS 1945 (1971) and satisfies the heating
appliance regulations (1991). However, a guard conforming to BS6539 (1984) must be used to
protect young children, the elderly or infirm.
This appliance incorporates a safety device in form of an oxygen depletion system. It must not
be adjusted or put out of operation. This is a non
–
serviceable item and must be exchanged as
a
complete assembly using only the original manufacturer’s part.
A suitable proprietary fire surround with a 150 degree C minimum rating is required.
Class One
That is a conventional brick or stone chimney as used for a solid fuel appliance with an effective
cross sectional dimension of 225 x 225mm or a lined flue with a minimum diameter of 125mm.
The chimney must have a minimum effective height of at least 3 metres. Any permanent flue
restriction or variable damper are to be removed or locked fully open. The chimney should be
swept prior to installation if it has previously been used with a gas appliance or if it is a new
installation.
The 890 HD is designed to be fitted into a class one flue with a fire place which will require a
50mm rebate. The other option is hole in the wall which can be plastered up to the edge of the
fire place frame or fitted with wall mounted non combustible slips. The two methods will require
different size apertures.
