The presence of high volume of water may create greater smoke while it burnt in the stove.


Sometimes the bag of pellet stove becomes damaged. You have to cover up the damaged portion of the pellet bag with water proof tapes.

Don’t store pellet in your living room or bedroom. It may attract the pest or insects. Also, pellet emits little amount of toxic gases (carbon monoxide) when it is stored. Find a safer place outside your home like garage or you can choose your storeroom for this purpose.  You need to use an exhaust or ventilation fan for safety.
