EDGE 60 Pellet Fireplace
D. Construct the Chase
You may enclose the vent system in a chase.
See Figures
27.1 & 27.2.
• Vertical chimneys on the side of building MUST be installed
in a chase.
Figure 27.2 - Chase Assembly
• Check local/regional building codes for compliance.
• Construct ouside wall of chase as you would the outside
walls of the building to prevent cold air drafting problems.
The chase should not break the outside building envelope
in any manner. All outer walls need to be insulated.
• Install vapor and air infiltration barriers per local/regional
building codes.
• Holes and other openings should be caulked with high
temperature caulk or stuffed with unfaced fiber glass
insulation.
COOLER CLIMATES
• In cooler climates, Hearth & Home Technologies Inc.
recommends you insulate walls, ceiling, base plate,
cantilever floor. Use batt type insulation between the
joists.
• Place a sheet of plywood or a raised platform on cement
slab under appliance only. Secure the appliance to the
cement slab.
• A firestop spacer should be installed in an insulated
false ceiling at the 8 ft. (.4m) level about the fireplace
assembly. This reduces heat loss through the chase. It is
required that firestops be installed every 10 ft (.05m) to
control spread of fire, but 8 ft is recommended to prevent
heat loss.
WARNING! You must install false ceilings and ceiling
firestops at each floor of the chase or every 10 ft (3.05 m)
to control spread of fire.
• Hearth & Home Technologies Inc. suggests you sheetrock
and tape (or use an equivalent method) all inside surfaces
of first level for maximum air tightness.
WARNING! Risk of Fire!
You must maintain the pellet pipe
manufacturer’s minimum air space clearance to insulation
and other materials surrounding the chimney system.
• Insulation and other materials must be firmly secured
to prevent accidental contact with chimney system.
• Failure to prevent contact between insulation or other
materials and chimney system may cause overheat-
ing and fire.
