Installation Instructions for VESTAL Circulator Fireplace
General:
The mason is urged to read these instructions carefully. Frequent reference to these instructions and drawings will help the
mason to do a perfect job of installing the Circulator Unit. Particular attention should be given to the application of the glass wool
insulation. The Circulator Unit must not be used as a support for the masonry. The masonry at all points must be self
−
supporting.
Keep masonry 1/2” to 1” away from the steel at all points to allow for normal heat expansion. See that any mortar squeezed from the
mortar joints does not touch the unit at any point.
Foundation
: Foundation dimensions will vary with the size of the Circulator used–type of masonry (brick or stone)–number and
size of any other flues in the same chimney–and width of fireplace on each side of the fireplace opening. Therefore, due to the
unlimited variety of applications for the Vestal Circulator Fireplace Unit, it is impossible to give specific details that cover all
installations and dimensions of the foundation.
The foundation is to be constructed of concrete or solid masonry and generally should be at least 12” thick and extend beyond the
masonry walls 6” on all sides unless codes or conditions call for greater thickness and/or extension.

Outside dimensions shown for standard and modular flues — inside dimensions for round flues. Chimney height is measured from hearth.
NOTE: Dimensions shown are actual measurements. Be sure to allow 1/2” to 1” space for glass wool insulation for heat expansion
between all points of the Circulator and the masonry.
