Install Guide
2 Getting Started
A. Design and Installation Considerations
Consideration must be given to:
• Safety
• Convenience
• Trafc ow
• Chimney and chimney connector required
It is a good idea to plan your installation on paper, using
exact measurements for clearances and oor protection,
before actually beginning the installation. If you are not
using an existing chimney, place the appliance where there
will be a clear passage for a factory-built listed chimney
through the ceiling and roof.
We recommend that a qualied building inspector and
your insurance company representative review your plans
before and after installation.
If this appliance is in an area where children may be near
it is recommended that you purchase a decorative barrier
to go in front of the appliance. Remember to always keep
children away while it is operating and do not let anyone
operate this appliance unless they are familiar with these
operating instructions.
Check building codes prior to installation.
• Installation MUST comply with local, regional, state
and national codes and regulations.
• Consult insurance carrier, local building, re ofcials
or authorities having jurisdiction about restrictions,
installation inspection, and permits.
CAUTION
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.
C. Negative Pressure
Negative pressure results from the imbalance of air
available for the appliance to operate properly. It can be
strongest in lower levels of the house.
Causes include:
• Exhaust fans (kitchen, bath, etc.)
• Range hoods
• Combustion air requirements for furnaces, water
appliances and other combustion appliances
• Clothes dryers
• Location of return-air vents to furnace or air
conditioning
• Imbalances of the HVAC air handling system
• Upper level air leaks such as:
- Recessed lighting
- Attic hatch
- Duct leaks
B. Fire Safety
To provide reasonable re safety, the following should be
given serious consideration:
1. Install at least one smoke detector on each oor of
your home to ensure your safety. They should be
located away from the heating appliance and close
to the sleeping areas. Follow the smoke detector
manufacturer’s placement and installation instructions,
and be sure to maintain regularly.
2. A conveniently located Class A re extinguisher to
contend with small res resulting from burning embers.
3. A CO detector should be installed in the room with the
appliance.
4. A practiced evacuation plan, consisting of at least two
escape routes.
5. A plan to deal with a chimney re as follows:
In the event of a chimney re:
a. Evacuate the house immediately
b. Notify re department.
WARNING
Asphyxiation Risk.
• Negative pressure can cause spillage
of combustion fumes, soot and carbon
monoxide.
• Appliance needs to draft properly for
safety.
WARNING
Asphyxiation Risk.
• Do NOT connect this appliance to a

A. Locating Your Appliance & Chimney
Location of the appliance and chimney will affect
performance. As shown in Figure 11.1 the chimney
should:
• Install through the warm space enclosed by the building
envelope. This helps to produce more draft, especially
during lighting and die down of the re.
• Penetrate the highest part of the roof. This minimizes
the affects of wind turbulence and down drafts.
• Consider the appliance location in order to avoid oor
and ceiling attic joists and rafters.
• Locate termination cap away from trees, adjacent
structures, uneven roof lines and other obstructions.
Your local dealer is the expert in your geographic area and
can usually make suggestions or discover solutions that will
easily correct your ue problem.

D. Chimney Height / Rise and Run
This product was designed for and tested on a 6 inch
(152mm) chimney, 14 to 16 feet (420-480cm) high,
(includes appliance height) measured from the base of the
appliance. The further your stack height or diameter varies
from this conguration, the greater the likelihood it may
affect performance.
Chimney height may need to be increased by 2 - 3% per
each 1000 feet above sea level. It is not recommended to
use offsets or elbows at altitudes above 4000 feet above
sea level or when there are other factors that affect ue
draft.
