Getting Started

AIR CONTROLS

Triple Air Systems

Several Yeoman appliances have triple air systems

providing cleaner burning, and greater efficiency and control,

see Diagram 2.

1) Airwash - air drawn over the window cleans the glass.

The source of Primary Combustion air when

burning wood.

2) Primary Air - for use initially when establishing fires and

the main air supply when burning solid fuels.

3) Cleanburn - Secondary air is preheated through a heat

exchanger to combust unburned hydrocarbons, providing

a cleaner and more efficient burn.

Manually operate the following air controls using the

tool provided.

Do not place tool on hot surfaces (e.g. top of appliance).

Secondary Control

Pull - OPEN

Push - CLOSE

Airwash Control

CLOSE OPEN

Primary Control

CLOSE OPEN

Thermostatic Control

The Secondary Air Control is located below the appliance

door, above the plinth. This control is used to adjust the

amount of 'Cleanburn' combustion air injected into the burning

flames. Push air control in to reduce and pull to increase the

flow of air.

DOOR OPERATION

Use a protected gloved hand to operate.

DO NOT OPEN THE DOOR WITH BARE HANDS

DO NOT OPEN THE DOORS WHEN THE FIREBOX IS

FULL OF FLAMES - WAIT FOR THEM TO DIE DOWN.

To Open and Close

Rotate handle and pull door to open

Warning: Do not force the handle

as damage may occur.

HEATING & HOT WATER SYSTEM CONTROLS

CONTROLS, GENERAL

1.15 As part of the installation of this appliance controls will have

been fitted to the heating and hot water system in order to

provide two functions:

—To control the comfort level in the house, see 1.16.

—To maintain safety in the event of misuse or mechanical

failure, see 1.18.

COMFORT CONTROLS

1.16 A programmable timer switches the pump on when heat is

required and off when it is not.

The timer, when combined with a room thermostat and / or

thermostatic radiator valves, enhances the comfort levels in

the house.

Some room thermostats combine the function with the timer

and can be programmed to reduce the room temperature

rather than turning the system off. This is effective in

not allowing rooms to become too cold and speeding up

recovery time.

1.17 The hot water cylinder can also be fitted with a thermostatic

valve which turns off the flow when the cylinder has reached

the desired temperature, but the heat leak radiator will have to

be bigger to cope with the extra load when the tank is isolated.

SAFETY CONTROLS

1.18 A high limit thermostat is fitted to the gravity flow pipe set at

80˚C.Thisthermostatshouldbeconnectedtothepumpso

thatthepumpisturnedonifthetemperatureexceeds80˚C.

This will prevent accidental boiling in the gravity circuit.
