Every stove is numbered and tested, and manufactured with
the best possible quality. These stoves are manufactured through
only one trained manufacturer located in Nepalgunj. Stove wall
is made of 1.5mm MS sheet and its cooking top surface is made
with 4mm thick MS sheet. It weighs about 40kg. The stove has
three potholes along with a slot for baking roti. Also, a nine litre
capacity stainless steel tank is attached in chimney for water
heating. Bottom of the stove is filled with double mud to prevent
heat loss. Adjustable air vent in the main door allows regulation
of draught air for combustion and damper in the fuel pipe is
used to transfer heat efficiently towards the cooking pots. The
average cooking efficiency may vary from 14 to 22 per cent. Life
expectancy is 15 years and is suitable for use above 2000 m
altitude.
