INSTALLATION PREPARATION
• You must use Model SF Firestop
• It is recommended for safety and reducing heat loss that firestopping be used at the
ceiling level for chase installation even if local codes do not require firestopping.
• Do not insulate chase with blown or fill type insulation. Only allow insulation to come
into contact with fireplace at points where fireplace would normally be contacted by
framing materials.

LOCATING CHIMNEY
(CONTINUED)
• If the fireplace is to be installed on an outside wall, the surrounding walls (chase) must be constructed and insulated.
See Figure 5. If you do not insulate the fireplace from outside temperatures, heat loss through and around the fireplace
will occur.
