P35i Fireplace Insert

C.Venting Requirements and Restrictions

A combustion blower is used to extract the combus- tion gases from the firebox. This causes a negative pres- sure in the firebox and a positive pressure in the venting system. The longer the vent pipe and more elbows used in the system, the greater the flow resistance.

The recommended maximum flue lengths for the P35i Insert are as follows:

3" or 4" Stainless Steel Flex: 30 Lineal ft. Vertical*

4" PL Vent Pipe:

4" Pl Vent Pipe: 30 Lineal ft. Vertical*

4" Pl Vent Pipe: 14 ft. Vertical w/1-90oand 12 lineal ft. horizontal*

If additional 4" PL Vent fittings are required, the overall length must be reduced by:

Vertical 90o or T:

2.5'

Vertical 45o:

1.5'

Horizontal

90o or T:

5.0'

Horizontal

45o:

2.5'

3" PL Vent Pipe:

20 Lineal ft. vertical*

8 Lineal ft. vertical w/1-90o& 8 lineal ft. horizontal*

If additional 3" PL Vent fittings are required, the overall length must be reduced by:

Vertical 90o or T:

2.0'

Vertical 45o:

1.0'

Horizontal

90o or T:

4.0'

Horizontal

45o:

2.0'

*Long runs of flex or PL vent pipe installed directly vertical from the flue stub may require more frequent cleaning due to fly ash falling off inside and collecting directly above the combustion blower outlet.

Any use of horizontal venting will require more frequent cleaning. It is the responsibility of the installer to make sure the entire flue configuration is accessible for cleaning.

Stainless steel flex vent is only allowed for use in masonry fireplaces and chimneys or in factory built wood burning fireplace installations when used as a liner for a class A metal chimney. All pellet vent pipe must be secured together by means provided by pipe manufac- turer. The vent pipe must be secured to the appliance flue collar with a minimum of three screws.

It is also recommended that you seal all vent pipe joints with high temperature silicone.

Use only the specified venting components. Use of any other components will void the product warranty and may pose a hazard.

DO NOT CONNECT THIS UNIT TO A CHIMNEY FLUE SERVING ANOTHER APPLIANCE.

NOTE: If burning a shelled corn and pellet mixture, you must use approved venting components that are specifically designed for corn burning.

WARNING! RISK OF FIRE!
