is 3.75Kw (12,800Btu’s/h) to water with all controls closed using the same fuel
load. The water capacity of the boiler is 7.1 litres.
The Domestic and Central Heating System
The domestic and central heating system must comply with BS:5449 Part 1.
When fitting a joint central heating & domestic hot water system, it must be a
double feed indirect hot water system storage type incorporating rust inhibitor to
prevent corrosion & scale( normally gravity primary & pumped domestic)
A distance of 50 feet in height between the flow tapping and the header tank is
the maximum permissible.
The system should include a heat link radiator to dissipate excess domestic hot
water when required. Also an injector tee should be fitted to promote an
adequate supply of domestic return water, when the heating system is in
operation.
The Boiler Tappings are 1” diameter BSP and should be connected so the primary
flow and return pipes rise continuously to the open vent.
In order to promote a warm return water temperature a pipe thermostat should
be fitted on the domestic return and set at 45 degrees centigrade. Other controls
such as a pump programmer, room & radiator thermostats can all be utilised
without affecting the appliance thermostatic air control.
Important.
A warm return water temperature to the boiler is essential when burning wood to
avoid the build up tar/resin & condensate forming on the boiler surfaces and
firebox. A suitable pipe thermostat or other means should be attached to control
the temperature of the return water. Failure to observe this warning could result
in cooler water temperatures and extensive boiler damage as well as negating
your stove guarantee.
Final Checks
After the system has been filled with water, light the appliance and check that all
combustion products are being taken from the appliance and exhausted up the
