Venting; Equivalent Vent Length (Evl) - Golden Eagle WOOD PELLET STOVE Operating & Installation Manual

VENTING
The choices you make when determining how your vent pipe is configured is very important and will
have an impact on the performance of your unit. In order to get the best performance from your
stove we highly encourage you to follow all installation directions in this manual. It will save you a
great deal of time and trouble if you properly vent your unit.
The Monroe is certified for use with listed TYPE L‐Vent, 3" or 4" diameter in size. The stove was
tested with Simpson Duravent brand. Class "A" chimney is not required. Refer to the instructions
provided by the vent manufacturer, especially when passing through a wall, ceiling or roof.
THIS IS A PRESSURIZED EXHAUST SYSTEM. ALL VENT CONNECTOR JOINTS MUST BE
SEALED WITH 500F (260C) RTV SILICONE SEALANT TO ENSURE CONSISTENT
PERFORMANCE AND AVOID SMOKE SPILLAGE. ALL HORIZONTAL CONNECTOR JOINTS
MUST BE SEALED WITH UL‐181‐AP FOIL TAPE.
DO NOT CONNECT THIS UNIT TO A CHIMNEY FLUE SERVING ANOTHER APPLIANCE.
DO NOT INSTALL A FLUE DAMPER IN THE EXHAUST VENTING SYSTEM OF THIS UNIT.
INSTALL VENT AT CLEARANCES SPECIFIED BY THE VENT MANUFACTURER.
Equivalent Vent Length (EVL)
Prior to purchasing your pellet vent pipe (type L) you should plan your venting scenario in to
determine the diameter of vent pipe you should use. Pellet vent pipe comes in 3" and 4" diameter.
In order to determine if you can use 3" diameter pipe, you need to calculate your EVL (Equivalent
Vent Length). To properly calculate your EVL you should make a simple sketch of your planned
installation. Then use the figures below to determine your EVL:

90 degree elbows or cleanout tees count as 5' of pipe

45 degree elbows count as 3' of pipe

Pipe running horizontally counts as 1' of pipe for 1' of pipe

Pipe running vertically counts as 1/2' of pipe for 1' of pipe
Use the above figures to calculate what your planned EVL will be. If your EVL is less than 15' you can
use 3" diameter pipe. If your EVL is 15' or more you should use 4" diameter pipe. If you need to use
4" pipe you should have a 3" to 4" transition right off the back of the unit and then use 4" diameter
pipe throughout the entire exhaust system.
If above 3,000' in elevation, you should use only 4" diameter pipe. In addition, if installing
the unit in a corner and going out a sidewall, we highly recommend that you use 4" pipe
regardless of your EVL or elevation.
