Wood Burning

If burning wood then it should be burnt on the cast grate and V boards. (Coal or smokeless fuel cannot be burned
in this way).
Allow t he a sh t o b uild u p t o a bout 1 " ( 25mm) d eep i n t he b ase t o e nsure e ven a nd e fficient b urning.
Ash Removal. After several burns as the ash builds then it can be raked through the cast grate so as to fall in
the ash pan below. This can be emptied by sliding out. If ash builds at the sides and cannot be removed through
the cast grate then it is desirable to clean out a few shovels full of the surplus ash as required. (This will be more
frequent if burning heavily).

Lighting with Wood

When lighting the fire, the air control should be opened fully by sliding the operating lever to the fully open
position. T he fi re m ay b e l it u sing p roprietary fi relighters w ith k indling w ood. T he d oor s hould b e l eft s lightly o pen

See sections on Use of Air Supply Control and Fuels below.
DO NOT USE THE APPLIANCE AS AN OPEN FIRE ALWAYS USE IT WITH THE DOOR CLOSED.

Basket Grates

Use the basket grate for burning coal or smokeless fuels, alone or mixed with wood.
If burning wood alone then it should be burnt on the cast grate and V boards.
Ash Removal. The removable ash pan simply slides out from under the cast grate for easy emptying. Do not
allow ash to build up under the basket grate bars. If they are allowed to become covered they will overheat
and it will seriously reduce the life of the basket grate. See Fitting the Basket in the Installation section of this
booklet.

Lighting with Basket Grate

When using smokeless fuel place the fuel around the edge of the basket forming a circle or two circles. Leave a

below.

Use of the Air Supply Control

The air control lever adjusts the primary air. The secondary air supply is pre-set to create simplicity for the user
to operate just one control. The primary and secondary air creates an air wash system drawing air across the
glass. This helps to keep the glass clean.
It reduces or increases the amount of air drawn into the fire to give the optimum burn and to carry away the
smoke. I t a lso h as a n e ffect u pon t he b urning r ate o f t he fi re. T he d egree o f c ontrol e xercised b y t he a ir c ontrol
lever is dependent on the draw of the chimney.
When l ighting t he fi re, t he a ir c ontrol s hould b e o pened f ully b y s liding t he o perating l ever t o t he o pen p osition.
Once the fire is established, the operating lever may be slid back to a position where the air supply is as far
closed as possible while maintaining smoke or fume clearance and the glass clear. Whenever fuel is added to
the fi re, t he a ir s upply l ever s hould o nce a gain b e o pened f ully u ntil t he f uel i s w ell a light.
When operating the fire on a weak flue (as in some bungalows with relatively short chimneys) the optimum
position of the air supply lever may be half open or more.
