INSTALLATION
Because each installation is unique to the property, it is not possible to give full details of the
constructional hearth setting. However, this should be constructed to comply with the
requirements of the Building Regulations and be made using “best practice” construction
methods. Remember that many fireplace openings will have a supporting lintel. Do not
remove this without making provision to support the remaining structure of the building.
The Stockton stove must not form any part of the supporting structure.
1. INSTALLING THE STOVE
1.1 Decide if the installation is to be top or rear flue exit, and fit and seal the flue collar
and blanking plate to suit. The flue collar attaches to the stove backplate or top plate
with hexagonal headed bolts. The blanking plate is fixed to the unused flue outlet
with fixing nuts.
1.2 Lift the stove into position on the prepared hearth area, taking care not to damage
the hearth finish.
1.3 Connect the stove to the chimney system, using Stovax enamelled flue pipe and seal
the connecting joints.
2. INSTALLING THE BOILER
2.1 The Stockton boiler is not to be used on sealed or pressurised heating circuits.
2.2 Gravity installation horizontal pipes must have an incline of at least 5mm / 1000mm,
and have a minimum diameter of 28mm (1"). Reductions can be made to vertical pipes.
2.3 Radiators larger than 1500mm (5’) wide and heat sink radiators should be connected
using diagonal connections.
2.4 The circuit should be fitted with an adjustable circulating pump to enable the flow to
be matched to the system requirements. This can be fitted to either the flow or return
pipework, and must be fitted with isolation valves to enable removal for maintenance.
2.5 The circulating pump static head should be a minimum of 1.5m (60"), measured
between the cistern tank and the pump centre line.
2.6 The cistern tank should have an overflow with a minimum diameter of 22mm (3/4")
and a feed, connected as the last connection on the common boiler return, of 22mm
