- MOBILE HOME APPROVED
- CHECK WITH LOCAL AUTHORITIES AND OBTAIN NEEDED PERMITS. OBTAIN
FINAL INSPECTION FROM LOCAL BUILDING OFFICIALS.
- WE RECOMMEND INSTALLATION BY A QUALIFIED PROFESSIONAL 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 STOVE.
- THIS STOVE USES A POSITIVE PRESSURE VENTING SYSTEM. DO NOT
INSTALL A FLUE DAMPER IN THE EXHAUST SYSTEM OF UNIT.
- DO NOT CONNECT THIS STOVE TO A CHIMNEY SYSTEM THAT IS
CONNECTED TO ANOTHER APPLIANCE.
- DO NOT INSTALL THIS UNIT IN A SLEEPING ROOM.
- INSTALL A SMOKE DETECTOR IN PROXIMITY OF THE STOVE.
- INSTALL A CARBON MONOXIDE DETECTOR IN PROXIMITY OF THE STOVE
ATTENTION
- CONDENSATION : When planning the installation of your Stove, keep in mind that
condensation is detrimental to exhaust systems. Install the Stove with a minimum of the
vent system exposed to the cold temperatures outside the envelope of the house.
- BATTERY BACKUP: St Croix does not offer battery backups. They are available online
if you decide to use one. Battery backup systems are useful if the Stove is installed using
horizontal venting only. This prevents any smoke from entering your home in the event of a
power failure.
- OPTIONAL EXHAUST FAN RELAY KIT: With optional relay kit 80P54232 installed in
the stove and connected to an inexpensive UPS battery backup (not part of the kit) you will
have maximum protection against smoke leaking out of the stove in the event of a power
failure. This is considered the best installation when venting horizontally. Contact your
dealer for more information.
1. All joints of PL vent and single wall stainless steel pipe should be fastened by at least 3
screws and correctly installed. (Follow vent manufacturer’s instructions). Seal all joints with
high temperature silicone to create an airtight seal.
INSTALLATION CHECK LIST

2. A certain amount of carbon monoxide may be produced within the Stove as a by-product of
combustion. All exhaust vent connections must be sealed with RTV silicone to assure a gas tight
seal. Any leaks into a confined area caused by faulty installation or improper operation of
the Stove could produce dizziness, nausea and in extreme cases, death. The CO
concentration in the flue gas during the testing of the Ashby-P was found to be too low and under
the accuracy of the test equipment used for the flue gas analysis. Therefore, the CO emissions
could not be calculated. The Ashby-MF is a “Non-Affected Facility” and was not tested.
3. WARNING: The high temperature paint on this Stove may take several hours of burning at a
high fuel setting to cure fully. During this time, an odor that is not harmful may be evident.
When odors are present, the area around the Stove should be well ventilated.
4. Caution: The high temperature paint can be easily scratched prior to burning the Stove.
5. Have your dealer demonstrate all the operational and maintenance steps necessary for proper
use of the Stove. Sign and return the warranty card to the address listed on the back page.
6. Some odors may be given off during the first few hours of burning during initial break-in.
These odors are normal and not harmful. However, ventilating the room until the odors disappear
is recommended.
7. The Stove will become HOT while in operation. Keep clothing and furniture away from all hot
surfaces.
8. To avoid the possibility of smoke and/or sparks entering the room always keep firebox and ash
pan doors closed whenever the Stove is operating. Smoke detectors, installed in the same general
area as the Stove, may be activated if the Stove door is left open and smoke is allowed to enter
the area.
9. Under certain circumstances an outside source of combustion air may be needed and is
required on all mobile home installations. Use only approved parts. When using outside air for
combustion, check that the outside air inlet is connected to draw fresh air from outside the
building. If room air is used to supply combustion air, room air starvation (not enough make-up
air), operation of exhaust fans and icing of air vents can adversely affect proper Stove operation.
This Multi-Fuel heater has a manufacturer-set minimum low burn rate that must not be altered. It
is against federal regulations to alter this setting or otherwise operate this Multi-Fuel heater in a
manner inconsistent with operating instructions in this manual.
CAUTION: FAILURE TO FOLLOW THE INSTRUCTIONS IN THE INSTALLATIONS
MANUAL MAY RESULT IN A HOUSE FIRE, PROPERTY DAMAGE, BODILY
INJURY, OR EVEN DEATH. PLEASE FOLLOW INSTALLATION AND
MAINTENANCE INSTRUCTIONS.
CAUTION: NEVER ADD FIRE STARTER TO A HOT STOVE.
CAUTION - Hot Surfaces
- Keep Children away.
- Do not touch during Operation.

Stove Layout
Figure 1
There are two burn systems used in the Ashby Series. These systems are interchangeable in the
stove body. This Manual covers the ASHBY-MF, which uses the Multi-Fuel Burn System
The Multi-Fuel Burn System is the St. Croix Patented “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-MF after removing the clinker. This burn system does
not have Self-Ignition. It is only approved for Corn, Wheat, Rye, Cherry Pits & Distillers Grain.
Wood pellets are no longer approved for use (except as starter pellets) in Ashby-MF’s built after
the 2015 NSPS.

VENTING: APPROVED MATERIALS
The Ashby-MF 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 Dura Vent 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-MF. 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-MF.
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 5)
2. It is not recommended to run vertical venting outside the heated environment where the
Ashby-MF 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-MF’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 on the next page in figure 10.
