More Product Info
The Green Mountain 20 was designed to be simple to use, easy to maintain, and sized for small living spaces. The square plate on the top of the stove is finished with our food grade enamel, so it’s easy to heat things up and clean up any spills. The catalyst slides back to engage once the fire is hot. The slide system helps you remember to engage the catalyst for a clean burn.
