E. Construct the Chase
You may enclose the vent system in a chase. See Figures
27.1 & 27.2.
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 infi ltration barriers per local/regional
building codes.
• Holes and other openings should be caulked with high
temperature caulk or fi lled with unfaced fi ber glass
insulation.
COOLER CLIMATES
• In cooler climates, Hearth & Home Technologies Inc.
recommends you insulate walls, ceiling, base plate,
cantilever fl oor. Use batt type insulation between the
joists.
• Place a sheet of plywood or a raised platform on
cement slab under appliance only. You need to secure
the appliance to the cement slab so do not extend the
plywood so as to interfer with the attachment.
• A fi restop spacer should be installed in an insulated
false ceiling at the 8 ft. (2.4m) level above the fi replace
assembly. This reduces heat loss through the chase. It is
required that fi restops be installed every 10 ft (3.05m) to
control spread of fi re, but 8 ft is recommended to prevent
heat loss.
WARNING! You must install false ceilings and ceiling
fi restops at each fl oor of the chase or every 10 ft (3.05 m)
to control spread of fi re.
• Hearth & Home Technologies Inc. suggests you sheetrock
and tape (or use an equivalent method) all inside surfaces
of fi rst 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 fi rmly 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 fi re.
