Yosemite Wood Stove
C. Negative Pressure
Draft is the pressure difference needed to vent appliances
successfully. Considerations for successful draft include:
• Preventing negative pressure
• Location of appliance and chimney
Negative pressure results from the imbalance of air avail-
able for the stove to operate properly. Causes for this imbal-
ance include:
• Exhaust fans (kitchen, bath) etc.)
• Range hoods
• Combustion air requirements for furnaces, water
heaters and other combustion appliances
• Clothes dryers
• Location of return-air vents to furnace or air condi-
tioning
• Imbalances of HVAC air handling system
• Upper level air leaks
• Recessed lighting
• Attic hatch opening
• Duct leaks
Recommended Location:
• Above peak
Recommended Location:
• Inside heated space
• Above peak
Marginal Location:
• Below peak
Location NOT recommended:
• Not the highest point of the roof
• Wind loading possible
Recommended:
• Insulated exterior chase
in cooler climates
Windward
Multi-level Roofs
Recommended:
Outside Air Intake
on windward side

To minimize the affects of negative air pressure the follow-
ing must be considered:
• Install the outside air kit. Install the intake on the
side of the house towards prevailing winds during
the heating season.
• Ensure adequate outdoor air is supplied for combus-
tion appliances and exhaust equipment.
• Ensure furnace and air conditioning return vents are
not located in the immediate vicinity of the appliance,
• Avoid installing the appliance near doors, walkways
or small isolated spaces.
• Recessed lighting should be of "sealed can" design;
attic hatches weather stripped or sealed; and attic
mounted ductwork and air handler joints and seams
taped or sealed.
WARNING
Asphyxiation Risk.
• Negative pressure can cause spillage of
combustion fumes, soot and carbon mon-
oxide.
• Appliance needs to draft properly for
safety.
Marginal Location:
• Wind loading possible
Location NOT recommended:
• Too close to tree
• Below adjacent structure
• Lower roof line
• Avoid outside wall
Leeward
NOT recommended:
Outside Air Intake

D. Flue Draft Considerations
Location of the appliance and chimney will affect perfor-
mance. As shown in Figure 6.1 on page 6 the chimney
should:
• Be installed through the warm space enclosed by the
building envelope. This helps to produce more draft,
especially during lighting and die down of the fire.
• 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
floor and ceiling attic joists and rafters.
Exterior conditions such as roof line, surrounding trees,
prevailing winds and nearby hills can influence stove
performance. Your local dealer is the expert in your geographic
area and can usually make suggestions or discover solutions
that will easily correct your flue problem.
To be sure that your appliance burns properly, the chimney
draft (static pressure) should be approximately -.04 inch water
column (W.C.) during a low burn and -.10 inch W.C. during a
high burn, measured 6 inches (152mm) above the top of the
appliance after one hour of operation at each burn setting.
NOTE: These are guidelines only, and may vary somewhat
for individual installations.
E. Venting Systems
The venting system consists of a chimney connector (also
known as stove pipe) and a chimney. These get extremely
hot during use. Temperatures inside the chimney may
exceed 2000°F (1100°C) in the event of a creosote fire. To
protect against the possibility of a house fire, the chimney
connector and chimney must be properly installed and
maintained. An approved thimble must be used when a
connection is made through a combustible wall to a chimney.
A chimney support package must be used when a connection
is made through the ceiling to a prefabricated chimney.
These accessories are absolutely necessary to provide
safe clearances to combustible wall and ceiling material.
Follow venting manufacturer's clearances when installing
venting system.

F. Tools And Supplies Needed
Before beginning the installation be sure that the following
tools and building supplies are available.
Reciprocating saw
Pliers
Hammer
Phillips Head Screwdriver
Flat Blade Screwdriver
Plumb Line
Level
Tape Measure
G. Inspect Appliance & Components and
Pre-Burn Check List
1. Place the appliance in a location near the final
installation area and follow the procedures below:
2. Open the appliance and remove all the parts and
articles packed inside the Component Pack. Inspect
all the parts and glass for shipping damage. Contact
your dealer if any irregularities are noticed.
3. All safety warnings have been read and followed.
4. This Owner's Manual has been read.
5. Floor protection requirements have been met.
6. Venting is properly installed.
7. The proper clearances from the appliance and
chimney to combustible materials have been met.
8. The masonry chimney is inspected by a professional
and is clean, or the factory built metal chimney is
installed according to the manufacturer's instruc-
tions and clearances.
9. The chimney meets the required minimum height.
10. All labels have been removed from the glass door.
11. A power outlet is available nearby if installing
optional blower assembly.
