Venting; Type Of Vent; Pellet Vent Installation - Cumberland Stove Works MF3800 Operator's Manual

VENTING

Consult vent manufacturer's specifications and
recommendations for all venting installations.
The following installation guidelines must be followed to
ensure conformity with both the safety listing of this stove
and to local building codes.
note: where passage through a wall, or partition of
combustible construction is desired, the installation
shall conform to Can/CSa -8365.

TYPE OF VENT

Pellet venting pipe (also known as L vent) is constructed
of two layers with air space between the layers. This air
space acts as an insulator and reduces outside surface
temperature of pipe to allow a clearance to combustibles.
A UL listed 3" or 4" type L pellet vent exhaust system must
be used for installation and attached to the pipe connector
provided on the back of the stove. Use a 3" to 4" adapter
for 4" pipe. A cap must be used at the termination of type
L vent chimneys. For elevations above 2,500 feet above
sea level, a 4" L is required.

PELLET VENT INSTALLATION

Termination MUST exhaust above air inlet elevation.
It is recommended to install at least 3' of vertical 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.
The installation must include a clean out tee to enable
collection of fly ash and to permit periodic cleaning of the
exhaust system.
Total length of horizontal vent must not exceed 10 feet.
The maximum recommended vertical venting height is 18
feet. All joints for pellet vent are required to be fastened
with at least three screws and all pellet vent connections
must be sealed according to the vent manufacturer's
recommendations.
The area where the vent pipe goes through 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.
