barbas UNIVERSAL-6 70 Instructions For Use & Maintenance Manual page 16

We recommend that you maintain a substantial layer of ash (2 - 3 cm). This not only
forms a protective layer for the base of the appliance but also signifi cantly reduces
consumption of fuel and allows new wood to catch light easier.
When loading the appliance with fuel, two blocks measuring ca. 30 cm long and 30 cm
perimeter is suffi cient. Only load again when the last fl ames have disappeared. This
ê
is after approximately 45 minutes. Do not leave the door open longer than necessary.
The maximum amount of fuel specifi ed in this manual should not be exceeded,
overloading can cause excess smoke and damage to the appliance.
Refuelling on to a low fi re bed.
If there is insuffi cient burning material in the fi rebed to light a new fuel charge,
excessive smoke emision can occur. Refuelling must be carried out onto a suffi cient
quantity of glowing embers and ash that the new fuel charge will ignite in a reasonable
period. If there are too few embers in the fi rebed, add suitable kindling to prevent
excessive smoke.
Weather conditions
In order to reduce pollution and any other inconvenience, we advise not fi ring up the
appliance when there is no wind, or in foggy/misty conditions.
Smoke development
Your appliance has been designed to be used with the load/observation door closed.
Should you use it with the door open, under certain circumstances (presence of
mechanical ventilation, draught, differences in barometric pressure) smoke may enter
the room in which the appliance is situated.
Use of the appliance
Your appliance is suitable for periodic use.
The appliance may only be positioned in a place where the location, construction and
activity in the room can accommodate it without danger.
