May be necessary where danger of fire is extreme, however, secondary combustion in Chofu prevents most sparks from escaping chimney. Adding a chimney cap reduces draw through stove, slowing the heating rate. Ten feet or more of pipe is necessary when using a chimney cap, to maintain maximum heat rate. Stovepipe with a chimney cap must always be supported to provide stability.
Order the A-CHOFUBRACE bracket as a connection point for this extra support.
