Serenity Pellet Stove
INSTALLATION
It is recommended the stove be installed and serviced by
authorized professionals who are certied by the National
Fireplace Institute (NFI) as NFI Pellet Specialists.
Proper installation of this stove is necessary for safe and ecient
operation. Installing this product improperly may result in a house
re and personal injury. All applicable building codes for your
location must be followed. In areas where building codes require
additional steps to the installation of this product not included
in this manual, the building codes will take precedent and must
be followed. Contact your local building inspector to obtain any
necessary permits or inspection guidelines before installing the
product.
Stove Placement
Sketch out a plan for installing the stove including dimensions
before permanent placement. When determining the location for
the stove, wall stud location is critical. You may need to adjust the
location of the stove to avoid trying to vent through a wall stud.
Before placing the pellet stove, connect the vent and allow for
minimum clearance to combustible walls.
Floor Protection Requirements
The stove must be installed on a noncombustible oor, with
proper oor protection, or on a masonry hearth. When a clean
out t-vent is installed in the inside of a home, the oor protector
must extend 2”beyond rear of t-vent. SEE FIGURE 1. When stove
is vented straight through the wall and the clean out t-vent is on
the exterior of the home, the minimum clearance is 2”from the
back of the stove to the wall. SEE FIGURE 2.The minimum oor
protector material is 24 GA sheet metal.

Clearances To Combustibles
NOTE: These are minimum clearances to combustible walls established by the ASTM testing lab. (SEE FIGURES 3, 4, 5, & 6.)
NOTE: When interior vent is installed vertically, the clearance to the back wall is determined by the vent size used. Install
vent at clearance specied by the vent manufacturer. Take into consideration any upward turning elbows or tees.

Serenity Pellet Stove
Venting
Before venting, consult vent manufacturer’s specications 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
The 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 Stove Vent Installation
Vent termination MUST exhaust above air inlet elevation.
It is required to install at least three feet (3’) of vertical pellet vent
pipe. This vertical pipe will create some natural draft to prevent
the possibility of smoke or odor during appliance shutdown
and will keep exhaust from causing a nuisance or hazard from
exposure to high temperatures.
The installation must include a clean out tee to enable collection
of y 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
(including adapters, elbows, etc.) should be sealed
airtight by injecting 500° F. RTV silicone into the
gap between sections.
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.

Preferred Pellet Vent Termination Clearances
• The stove vent must terminate on the outside of the building. Horizontal terminations must extend a minimum
of 12”from the wall. Vertical terminations must protrude a minimum 24”from the roof surface. In addition, all
clearances listed below must be met. SEE FIGURE 7.
• Must have an approved cap (to prevent water from entering) or a 45° downturn with rodent screen.
• If the termination is located on a windy side of the house, we suggest using an approved house shield to prevent
soot from building up on the side of the house.
• A vent must not be located where it will become plugged by snow or other material.
A: A Minimum 4’clearance below or beside any door or
window that opens. (This clearance may be reduced
to 18”if using outside air). We recommend the door or
window be kept closed during operation. Minimum 1’
clearance below or beside any window that does not
open.
B: Minimum 1’clearance above any door or window that
opens.
C: Minimum 2’ clearance from any adjacent building.
D: Minimum 7’clearance above any grade when adjacent to
public walkways.
NOTE: Vent may not terminate in covered walkway or
breezeway.
E: Minimum 2’clearance above any grass, plants, or other

Outside Air Connection
Connection from the intake pipe (2”diameter pipe in rear of stove,
See Figure 8) to the outside of the house is REQUIRED for mobile
home installation. It is recommended in tightly sealed homes
with exhaust fans such as kitchen or bathroom fans. This will
eliminate poor performance due to negative pressure.
Only noncombustible pipe 2”(or greater) in diameter is approved
to use for outside air connections (straight or exible).
NOTE: PVC pipe is NOT approved and should NEVER be
connected to the stove.
HINT: A Castle Pellet Stove air inlet will accept
automotive exhaust pipes and couplers
If the air inlet is connected to the outside, it MUST be terminated
with a vertical 90ºbend (down) or with a wind hood. Failure to do
so could result in a burn back during high winds blowing directly
up the air inlet during a simultaneous power failure.
Blockage, excessive length, or extra bends in the air intake pipe
will starve the stove of combustion air. A 90º bend is equivalent in
restriction to approximately 30”of straight inlet pipe.
Mobile Home
Installation in a mobile home should be in accordance with the
manufactured home and safety standard. Department of Housing
and Urban Development (HUD) CITE: 24CFR3280.707 stating
this stove must be vented to the outside. In addition to the
standard installation instructions, the following requirements are
mandatory for installation in a mobile home:
1. The stove must be permanently attached to the oor.
2. Stove must have an outside air source.
3. Stove must be electrically grounded to the steel chassis
of the mobile home.
4. All vertical chimney vents must have wall supports.
5. All exhaust systems must have a spark arrestor.
6. Check with local building ocials to see if other codes
may apply.
CARBON MONOXIDE POISONING HAZARD. DO
NOT CONNECT TO ANY AIR DISTRIBUTION DUCT
OR SYSTEM. DO NOT INSTALL IN A SLEEPING
ROOM.
WARNING
THE OPERATION OF EXHAUST FANS SUCH AS
BATHROOM FANS, ATTIC FANS, ETC. MIGHT
STARVE THE PELLET STOVE OF COMBUSTIBLE AIR
CREATING A NEGATIVE PRESSURE IN THE ROOM.
PROVIDE ADEQUATE VENTILATION IN THE ROOM
ACCOMPANYING THE PELLET STOVE. IF NOT, THE
PRESSURE SWITCH MAY SHUT OFF OPERATION
OF THE PELLET STOVE.
THE STRUCTURAL INTEGRITY OF THE
MANUFACTURED HOME FLOOR, WALL, AND
CEILING/ROOF MUST BE MAINTAINED.
