Multifuel Grate
Your Parkray Stove is fitted with a locomotive type grate. So that
de-ashing can be carried out cleanly and easily, it is riddled from the
outside of the stove with the doors closed. The grate is designed to
burn both wood and solid fuels.
To burn solid mineral fuels
place the operating tool over the
riddling spigot and pull it down towards you. When left in that
position, air is directed under and up through the slots in the firebed,
giving the optimum conditions for burning solid fuels.
It is important that the riddling tool is used to remove the ash to
ensure airflow through the firebed and allow the fire to burn over the
entire area of the grate.
The ashpan should be emptied at least daily and ash should never be allowed to build up over a
period of time as this will result in damage to the fire bars. The flat end of the riddling tool can
be used to carry the ashpan.
To burn wood
, push the operating tool up and away from you. When left in this position, air is
restricted through the bed of the fire providing a solid base to build up a bed of ash. Surplus ash
can be removed either by gentle riddling or with a shovel.
It might prove beneficial when burning more reactive fuels to leave the grate in a “neutral”
position, thus directing some under fire air and some over fire air to the firebed.
Notes on solid mineral fuel burning
Solid mineral fuel should be placed in the stove so that there is no more than a 30° incline of the
fuel bed from front to back. It should
not
be stacked above the bottom of the baffle as this may
result in damage to the stove.
With a full load of fuel, the stove will need to be refuelled approximately once every 4 hours.
Solid mineral fuel burns most efficiently with the secondary air control in the closed position.
The primary air sliders can then be used to control the burn rate of the stove.
Always de-ash before refuelling and do not let the ash build up to the underside of the grate bars.
Solid mineral fuel produces ash, which if allowed to build up will stifle the airflow through the
Primary air sliders and grate. This will eventually cause the fire to die.
With some solid mineral fuels a residue of burnt fuel or clinker will accumulate on the grate,
allow the fire to go out periodically to remove this.
Important!
-
We cannot stress firmly enough how important it is to empty the ashpan regularly.
Air passing through the firebed cools the grate bars. Distortion or burning out the grate bars is
nearly always caused by ash being allowed to build up to the underside of the grate.
