GUIDELINES FOR EXHAUST VENTING SYSTEMS DESIGN

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 backpufng 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.

Take into account the chimney’s location to insure it is not too close to neighbors or in a valley which may cause un-

healthy or nuisance conditions.

It is recommended that only an authorized installer install your multi-fuel heater, preferably an NFI certied

specialist. The following installation guidelines must be followed to ensure conformity with both the safety listing of this

heater and to local building codes.

INSTALL VENT AT CLEARANCES SPECIFIED BY THE VENT MANUFACTURER.

• A UL listed 3” or 4” type “PL” pellet vent exhaust system must be used for installation and attached to the pipe con-

nector provided on the back of the heater. Use a 3” to 4” adapter for 4” pipe. A cap must be used at the termination

of type “L” vent chimneys. 4” PL is required for elevations above 2,500 feet above sea level.

• Do not terminate vent in any enclosed or semi-enclosed area, such as; carports, garage, attic, crawl space, under a

sundeck or porch, narrow walkway or close area, or any location that can build up a concentration of fumes such as

a stairwell, covered breezeway etc.

• Vent surfaces can get hot enough to cause burns if touched by children. Noncombustible shielding or guards may be

required.

• Do not install a ue damper in the exhaust vent of this unit.

• Termination must exhaust above air inlet elevation. Installation MUST include three (3) vertical feet of pellet vent pipe.

This will create some natural draft to prevent the possibility of smoke or odor during appliance shutdown and to keep

exhaust from causing a nuisance or hazard from exposing people or shrubs to high temperatures. Do not connect

this unit to a chimney ue serving another appliance. Do not connect directly to a masonry chimney.

• The installation must include a cleanout tee to enable collection of y ash and to permit periodic cleaning of the ex-

haust system. 90

elbows accumulate y ash and soot thereby reducing exhaust ow and performance of the heater.

Each elbow or tee reduces draft potential by 30% to 50%. Use no more than 180 degrees of elbows (two 90-degree

elbows, or two 45-degree and one 90-degree elbow, etc.) and one cleanout tee to maintain adequate draft. Cleanout

tees and elbows should not be connected to the rear of the unit unless a 3-inch adapter is used.

• Total length of horizontal vent must not exceed 48”(4ft.)/1,200mm. The maximum recommended vertical venting

height is 12-feet for 3-inch type “PL” vent. For venting higher than 12-feet, 4-inch “PL” vent must be used. All joints

in the vent system must be fastened by at least 3 screws, and all joints must be sealed with RTV silicone sealer to be

airtight.

• The area where the vent pipe penetrates to the exterior of the home must be sealed with silicone or other means to

maintain the vapor barrier between the exterior and the interior of the home.

NOTE: These are guidelines only. Proper venting is accomplished by design and necessary require-

ments. In most installations 3 inch diameter venting is adequate. If it does not vent properly you will

have to change it to 4 inches. You should not exceed 4 inch diameter venting.
