There are two burn systems used in the Ashby. These systems are interchangeable in the stove
body. The first is the St. Croix Patent Pending “Clinker Removal System”. This burn pot
allows the clinker to be removed without loosing the fire in the pot. This eliminates the need of
having to constantly re-light the Ashby after removing the clinker. This burn system does not
have Self-Ignition. It is approved for Pellets Corn, Wheat, Rye, Cherry Pits & Distillers Grain
Pellets. See Figure 2 on the next page.
The second burn system uses the “Versa Grate System”. This system does have Self-Ignition.

Caution
INSTALLATION IS TO BE PERFORMED BY A QUALIFIED INSTALLER OR
DEALER.
ADHERE TO ALL CLEARANCES SPECIFIED BY THE MANUFACTURER OF THE
VENTING SYSTEM USED.
ADHERE TO ALL CLEARANCES SPECIFIED IN THE INSTALLATION
INSTRUCTIONS OF THIS MULTI-FUEL INSERT.
THIS MULTI-FUEL INSERT USES A POSITIVE PRESSURE VENT SYSTEM. DO
NOT INSTALL A FLUE DAMPER IN THE EXHAUST SYSTEM OF UNIT
DO NOT CONNECT THIS MULTI-FUEL INSERT TO A CHIMNEY SYSTEM THAT IS
CONNECTED TO ANOTHER APPLIANCE.
DO NOT INSTALL THIS UNIT IN A SLEEPING ROOM
ATTENTION
CONDENSATION:
Insert, keep in mind that condensation is detrimental to exhaust systems. Corn,
Wheat, & Rye have higher moisture content than pellets and can be more
susceptible to condensation forming in certain types of installations. Install the
Ashby with a minimum of the Vent system exposed to the cold temperatures
outside the envelope of the house. Insulate the vent system if in doubt. Check
with the manufacturer of your venting system that they honor the warranty of
their PL Vent with the use of corn.
When planning the installation of your Multi-Fuel
ATTENTION
BATTERY BACKUP: We strongly recommend using a battery backup system if
the Ashby is installed using horizontal venting only. This prevents any smoke
from entering your home in the event of a power failure. The battery back-up
system must provide “pure sine wave” power to operate the unit.

VENTING: APPROVED MATERIALS
The Ashby requires a venting system approved for pellet or corn venting by a certified testing
lab. Approved pellet or corn venting materials are: 1) PL vent, a double wall vent with a stainless
steel liner; and 2) Single wall rigid or flexible stainless steel pipe. PL Vent and Single wall vent
is available through manufacturers such as: Energy Vent LTD, James A. Ryder, Simpson
DuraVent and Selkirk Metalbestos and is carried by many local dealers. In this manual approved
venting will be referred to a “PL vent” or “Single wall vent”. All single wall vent adaptors must
be stainless steel.
NOTE: TYPE “B” GAS VENT MUST NOT BE USED IN THE INSTALLATION OF THIS
MULTI-FUEL INSERT
Examples of venting system components follow:
High temperature ceramic roping reduces potential fly ash escaping through joints.
Stainless steel inner liners resist corrosive flue gas damage to the system.
Flex pipe should be stainless steel, 4 ply construction with a total thickness of approximately .07
inches.

VENTING: DETERMINING MATERIALS
TYPE OF MATERIALS:
1. PL Vent / Corn Vent must be used.
2. All Joints in the venting installation must be fastened together using three screws. All joints of
the venting system must be sealed with High Temp Silicone to make a gas tight fit.
3. Exception: Single wall stainless steel may be used inside an existing chimney. (No
clearances to combustibles are needed on single wall stainless steel adaptors, rigid or flex pipe
installed within a chimney.)
4. A clean out “tee” has been built into the Ashby. This cleanout system is to assist in
periodically cleaning the vent pipe. The exhaust system can periodically be cleaned from the
inside of the unit without having to pull the unit from the fireplace.
NOTE: ADHERE TO THE PL VENT CLEARANCES TO COMBUSTIBLES AS REQUIRED.
STRICTLY OBSERVE THE PL VENT MANUFACTURER’S SAFETY SPECIFICATIONS.
QUANTITY OF MATERIALS:
1. It is recommended that the vent system be installed with a minimum of three feet (3’) of
vertical rise above the exhaust port on the back of the Ashby.
FAILURE TO PROVIDE THE NATURAL DRAFT THAT RESULTS FROM A VERTICAL
RISE MAY RESULT IN SMOKE BEING RELEASED INTO THE HOUSE WHEN
ELECTRICITY TO THE UNIT IS INTERRUPTED WHILE BURNING OR SMOLDERING
FUEL REMAINS IN THE BURN GRATE. (See “Battery Backup” on page 9)
2. It is not recommended to run vertical venting outside the heated environment where the Ashby
is installed. Running a venting system in a cold environment may cause the flue temperatures to
cool down too much for adequate drafting.
Additional vertical exhaust venting should be provided when using:
a. More than one (1) elbow or tee; and/or
b. Horizontal runs of over three (3) feet. (Horizontal runs over 10 feet not recommended)
3. For a venting system ending in a horizontal run, the exhaust pipe must be terminated by a
listed end cap or a PL vent elbow (45 or 90 degrees). Note: End caps or elbows must vent
exhaust gases away from the building.
4. For termination above the building roofline a rain cap is required.
5. The exhaust pipe on all Ashby’s is 3” O.D. to accommodate a pipe adaptor.

VENTING: TERMINATION REQUIREMENTS
In determining optimum vent termination, carefully evaluate external conditions especially when
venting directly through a wall. Since you must deal with odors, gases, and fly ash, consider
aesthetics, prevailing winds, distances from air inlets and combustibles, location of adjacent
structures and any code requirements.
1. Exhaust must terminate above combustion air inlet elevation.
2. Do not terminate vent in any enclosed or semi-enclosed area, (i.e. Carports, garage, attic
crawl space, etc.) or any location that can build up a concentration of fumes.
3. Vent surfaces can get hot enough to cause burns if touched by children. Non-combustible
shielding or guards may be required
The type of installation must first be considered before determining the exact location of
the venting termination in relation ship to doors, window, cavities or air vents.
a. Without Outside Air connected to the unit. For These types of installations please refer
to the dimensions listed below in figure 10a.
