Chimney Requirements - Heatilator EC36 Installation & Operating Instructions Manual

3. Sidewalls/Surrounds
Adjacent combustible side walls must be located a minimum of 12 in. from the fireplace opening. See Figure 6. If
you are using a decorative surround constructed of combustible material, it must be located within the shaded area
defined in Figure 6. Short stub walls are also acceptable if they are contained within the shaded area.
When planning your fireplace location, the chimney construction and necessary clearances must be considered. The
fireplace system and chimney components have been tested to provide flexibility in construction. The following figures
are the minimum distances from the base of the fireplace.
