Getting Started

A. Design and Installation Considerations
Check building codes prior to installation.
• Installation MUST comply with local, regional, state
and national codes and regulations.
• Consult insurance carrier, local building, fire officials
or authorities having jurisdiction about restrictions,
installation inspection, and permits.
Before installing, determine the following:
• Type of chimney connector to be used
- Single wall, 6 inch (152mm) diameter, stainless steel,
or
- Double wall, 6 inch (152mm) diameter, stainless steel
• Reference Clearance to Combustibles on page 10.
• Power outlet located close by for optional blower
Asphyxiation Risk.
• Do NOT connect this unit to a chimney flue
servicing another appliance.
• Do NOT connect to any air distribution
duct or system.
May allow flue gases to enter the house.

CAUTION
WARNING
B. Draft
Draft is the pressure difference needed to vent appliances
successfully. When a appliance is drafting successfully,
all combustion byproducts are exiting the home through
the chimney.
Considerations for successful draft include:
• Preventing negative pressure
• Location of appliance and chimney
To be sure that your appliance burns properly:
• During the burn, the chimney draft (static pressure)
should be approximately -0.07 inch water column (W.C.)
• Measure the W.C at 6 inches (152mm) above the top of
the appliance after one hour of operation.
NOTICE: Hearth & Home Technologies assumes no
responsibility for the improper performance of the
appliance system caused by:
• Inadequate draft due to environmental conditions
• Down drafts
• Tight sealing construction of the structure
• Mechanical exhausting devices
• Over drafting caused by excessive chimney heights
• Ideal performance is with height of chimney between
14-16 feet (4.26-4.88m) measured from the base of
the appliance.
