Information Related To Safety

1.

Unpacking and Handling of the Furnace 
Before operating the furnace please take note of following points.

This  furnace  has  been  packed  to  minimize  any  risk  due  to  transportation.  Remove  the 

packing with care; avoid using any kind of force and removing packing inserts slowly.

It is extremely important to remove the packing inserts from 
inside the furnace .Operating the furnace without removal 
of safety inserts will cause heavy damage on the heating elements.

Use furnace base while lifting and carrying the furnace.

Always use two persons to carry.

Always take note of the weight of furnace during placement.

Do not operate the furnace if there is inflammable material around. Ensure that the risk of 

fire is non-existent .Do not place the furnace on an inflammable surface.

Placement should be in a well ventilated room, with no interaction with other sources of 

heat. Do not place on an inflammable surface.

Air circulation, should be capable enough to remove any gas emission 
due to come through the lid or furnace chimney. Almost all gas 
emissions during operation can be hazardous for Human health 

Always give space of 30cm around the furnace to enable quick service. Do not close the 
vents on the furnace body. These are required to cool down the system.
