Venting

Use 4” pellet vent pipe only.

A combustion blower is used to extract the combustion gases from the firebox. This creates a negative pressure in the firebox and a positive pressure in the venting system as shown in Fig. 4. The longer the vent pipe and more elbows used in the system, the greater the flow resistance. Because of these facts we recommend using as few elbows as possible and 30 feet or less of vent pipe. The maximum horizontal run should not exceed 18 feet.

Be sure to use wall and ceiling pass through fittings (which are approved for pellet vent pipe ) when going through combustible materials. Be sure to use a starting collar to attach the venting system to the stove. The start- ing collar must be sealed to the stove flue collar with high temp silicone caulking or aluminum tape, and screwed into the stove flue collar at least three (3) places.

Vent Pipe

4” pellet vent pipe (also known as “PL” vent) is con- structed of two layers with air space between the layers. This air space acts as an insulator and reduces the outside surface temperature to allow a minimum clearance to combustibles as low as 1 inch. In Canada the minimum clearance to combustibles is 3 inches.

The sections of pipe lock together to form an air tight seal in most cases; however, in some cases a perfect seal is not achieved. For this reason and the fact that the boiler operates with a positive vent pressure, we specify that all joints within the structure should also be sealed with silicone.

NOTE:Use only 4” diameter approved PELLET venting system. Be sure to inspect and clean exhaust venting system frequently.

This is the minimum venting configuration.

The minimum vent configuration is a 90o or Tee on a starter collar and a 24” length horizontal through an exterior wall. A cap on the end should direct the flue gasses down and away from the structure. See Fig. 5.

The maximum horizontal length is 18 feet. The minimum termination height above the exterior grade is 18”. The maximum total length of any configuration is 30 feet*.

*( see venting graph on page 9 for exceptions )

NOTE: Cleanout Tee’s should always be used on the transitions to horizontal pipe to allow easy access for cleaning.

The venting graph allows for one(1) 90 deg. or Tee fitting in any configuration.

If more 90’s, T’s, or 45’s are needed, the total length must be adjusted to allow for the added restriction.

Up to four (4) additional 90’s, Tee’s, or equivalent 45’s can be added as long as the overall length is adjusted in accordance with the values listed below.

( See the venting graph on page 10.)

Each Vertical ---- 90 deg. or T subtract 2.5 feet

Each Vertical ---- 45 deg. subtract 1.5 feet

Each Horizontal - 90 deg. or T subtract 5.0 feet

Each Horizontal - 45 deg.

subtract 2.5 feet

Any exterior venting (vent pipe exposed to outside ambient temperatures) should be kept to a minimum, due to potential condensation problems.

This is especially important in high humidity cold weather climates, such as maritime areas, lake shores, and low river valleys.
