This appliance must be connected to a listed Stainless Steel Liner, that meets UL1777, which extends from the

collar to the chimney cap according to the specifications listed on the previous pages. Take into account the

chimney’s location to ensure it is not too close to neighbors or in a valley which may cause unhealthy or nuisance

conditions.

IMPORTANCE OF PROPER DRAFT

Draft is the force which moves air from the appliance up through the chimney. The amount of draft in your

chimney depends on the length of the chimney, local geography, nearby obstructions and other factors. Too

much draft may cause excessive temperatures in the appliance. Inadequate draft may cause backpuffing into

the room and “plugging” of the chimney. Inadequate draft will cause the appliance to leak smoke into the room

through appliance and chimney connector joints. An uncontrollable burn or excessive temperature indicates

excessive draft.

Chimneys perform two functions:

1. As a means of exhausting smoke and flue gases which are the result of fuel combustion.
2. The chimney provides “draft,” which allows oxygen to be continuously introduced into the appliance, so that

proper combustion is possible. This stove relies on natural draft to operate.

NOTICE: Always provide a source of fresh air into the room where the stove is located. Failure to do so may result

in air starvation of other fuel burning appliances and the possible development of hazardous conditions, fire, or

death.

Your appliance itself does not create draft. Draft is provided by the chimney. To help provide the required draft

there is a fresh air kit (4FAK) available for purchase from your local stove dealer. When installed properly the 4FAK

kit is designed to provide the draft needed for proper operation. To achieve proper draft your chimney must meet

the three minimum height requirements detailed in figure 8. A minimum draft of 0.05 w.c. (measured in water

column) is required for proper drafting to prevent back puffing, smoke spillage, and to maximize performance.

Gauges to measure draft are readily available at stove stores and are economical to rent or purchase. Factors

such as wind, barometric pressure, trees, terrain and chimney temperature can have an adverse effect on the

draft. The manufacturer cannot be held responsible for external factors leading to less than optimal drafting.

Should you have a problem with inadequate draft, you should contact a licensed heating and cooling contractor

for assistance in solving the problem.

IMPORTANT INSTALLATION POINTS

1.  Size chimney flue to appliance collar. This stove requires a minimum 6” diameter flue.
2.  Never connect this unit to a chimney serving another appliance.
3.  The chimney must meet all minimum height requirements.
4.  Never use a chimney to ventilate a cellar or basement.
Contact your local building authority for approved methods of installation and any necessary permits and/or

inspections.

MASONRY CHIMNEY

Before using an existing masonry chimney,

clean the chimney, inspect the flue liner,

and make any repairs needed to be sure

it is safe to use. As mentioned previously,

this appliance requires a continuous

stainless steel liner from the appliance

collar to the chimney cap. Make repairs

before attaching the stove. The connector

stove pipe and fittings you will need to

connect directly to a masonry chimney
