Installation  
VENTING REQUIREMENTS  
Ì
Ì
Ì
Install vent at clearances specified by the vent manufacturer.  
Do not connect the pellet vent to a vent serving any other appliance or stove.  
Do not install a flue damper in the exhaust venting system of this unit.  
The following installation guidelines must be followed to ensure conformity with both the safety listing of this stove and  
to local building codes.  
IMPORTANT! This unit is equipped with a negative draft system that pulls air through the burn pot and  
pushes the exhaust out of the dwelling. If this unit is connected to a flue system other than the way ex-  
plained in this manual, it will not function properly.  
MAXIMUM VENTING DISTANCE  
Installation MUST include at least 3-feet of vertical pipe. This will create some natural draft to reduce the possibility of  
smoke or odor during appliance shutdown and keep exhaust from causing a nuisance or hazard by exposing people or  
shrubs to high temperatures. The maximum recommend vertical venting height is 12-feet for 3-inch type “PL” vent. Total  
length of horizontal vent MUST NOT exceed 4-feet. Use no more than 180 degrees of elbows (two 90-degree elbows,  
or two 45-degree and one 90-degree elbow, etc.) to maintain adequate draft.  
PELLET VENT TYPE  
A UL listed 3-inch or 4-inch type “PL” 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-inch to 4-inch adapter for 4-inch pipe). Use 4-inch vent if the vent  
height is over 12-feet or if the installation is over 2,500 feet above sea level.  
We recommend the use of Simpson Dura-Vent® or Metal-Fab® pipe (if you use other pipe, consult your local building  
codes and/or building inspectors). Do not use Type-B Gas Vent pipe or galvanized pipe with this unit. The pellet vent  
pipe is designed to disassemble for cleaning and should be checked several times during the burning season. Pellet  
vent pipe is not furnished with the unit and must be purchased separately.  
PELLET VENT INSTALLATION  
The installation must include a clean-out tee to enable collection of fly ash and to permit periodic cleaning of the exhaust  
system. 90-degree elbows accumulate fly ash and soot thereby reducing exhaust flow and performance of the stove.  
Each elbow or tee reduces draft potential by 30% to 50%.  
All joints in the vent system must be fastened by at least 3 screws, and all joints must be sealed with HI-TEMP RTV  
silicone sealant to be airtight. The area where the vent pipe penetrates 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.  
Vent surfaces can get hot enough to cause burns if touched by children. Noncombustible shielding or guards may be  
required.  
PELLET VENT TERMINATION  
Do not terminate the vent in an enclosed or semi-enclosed area, such as; carport, garage, attic, crawl space, under a  
sundeck or porch, narrow walkway, or any other location that can build up a concentration of fumes.  
The termination must exhaust above the outside air inlet elevation.  
The termination must not be located where it will become plugged by snow or other materials.

Installation  
THROUGH THE WALL INSTALLATION (RECOMMENDED INSTALLATION)  
To vent the unit through the wall, connect the pipe adapter  
to the exhaust motor adapter. If the exhaust adapter is at  
least 18-inches above ground level, a straight section of  
pellet vent pipe can be used through the wall.  
Your King/Ashley dealer should be able to provide you  
with a kit that will handle most of this installation, which  
will include a wall thimble that will allow the proper  
clearance through a combustible wall. Once outside the  
structure, a 3-inch clearance should be maintained from  
the outside wall and a clean out tee should be placed on  
the pipe with a 90-degree turn away from the house. At  
this point, a 3-foot (minimum) section of pipe should be  
added with a horizontal cap, which would complete the  
installation (see FIGURE 7).  
A support bracket should be placed just below the  
termination cap or one every 4-feet to make the system  
more stable. If you live in an area that has heavy snowfall,  
it is recommended that the installation be taller than 3-feet  
to get above the snowdrift line. This same installation can  
be used if your stove is below ground level by simply adding  
the clean-out section and vertical pipe inside until ground  
level is reached. With this installation you have to be aware  
of the snowdrift line, dead grass, and leaves. We  
recommend a 3-foot minimum vertical rise on the inside  
or outside of the house.  
FIGURE 7  
TYPICAL THROUGH THE WALL INSTALLATION  
The “through the wall” installation is the least expensive and simplest installation. Never terminate the end vent under a  
deck, in an alcove, under a window, or between two windows. We recommend Simpson Dura-Vent® or Metal-Fab® kits.  
THROUGH THE ROOF/CEILING INSTALLATION  
When venting the stove through the ceiling, the pipe is connected the same as through the wall, except the clean-out tee  
is always on the inside of the house, and a 3-inch adapter is added before the clean-out tee.  
You must use the proper ceiling support flanges and roof flashing (supplied by the pipe manufacturer; follow the pipe  
manufacturer’s directions). It is important to note that if your vertical run of pipe is more than 15-feet, the pellet vent pipe  
size should be increased to 4-inches in diameter.  
Do not exceed more than 4-feet of pipe on a horizontal run and use as few elbows as possible. If an offset is required,  
it is better to install 45-degree elbows rather than 90-degree elbows.

Installation  
OUTSIDE AIR SUPPLY (optional)  
Depending on your location and home construction, outside air may be necessary for optimal performance.  
Metal pipe (solid or flexible) must be used for the outside air installation. PVC pipe is NOT approved and should NEVER  
be used.  
A wind shield over the termination of the outside air pipe or a 90-degree elbow or bend away from the prevailing winds  
MUST be used when an outside air pipe is installed through the side of a building. The outside air termination MUST be  
at least 1-foot away from the exhaust system termination.  
The outside air pipe on your King/Ashley stove is 1 7/8” OD. The outside air connecting pipe must be at least 1 7/8” ID.  
The outside air connection used MUST NOT restrict the amount of air available to your stove. The outside air connecting  
pipe must be as short and free of bends as possible, and it must fit over, not inside, the outside air connection to the  
stove.

SPECIAL MOBILE HOME REQUIREMENTS  
Ì
WARNING! - DO NOT INSTALL IN A SLEEPING ROOM  
Ì
CAUTION! - THE STRUCTURAL INTEGRITY OF THE MOBILE HOME FLOOR, WALL, AND CEILING/ROOF  
MUST BE MAINTAINED.  
In addition to the previously detailed installation requirements, mobile home installations must meet the following  
requirements:  
The stove must be permanently attached to the floor.  
The stove must be electrically grounded to the steel chassis of the mobile home with 8 GA copper wire using a  
serrated or star washer to penetrate paint or protective coating to ensure grounding.  
Vent must be 3 or 4-inch “PL” Vent and must extend a minimum or 36-inches above the roofline of the mobile home  
and must be installed using a UL/ULC listed ceiling fire stop and rain cap.  
When moving your mobile home, all exterior venting must be removed while the mobile home is being relocated.  
After relocation, all venting must be reinstalled and securely fastened.  
Check with your local building officials as other codes may apply.

Operation  
Ì Do not operate your stove with the viewing door open. The auger will not feed pellets under these  
circumstances and a safety concern may arise from sparks or fumes entering the room.  
Ì This heater is designed and approved for premium hardwood pellet fuel only. Any other type of fuel burned  
in this heater will void the warranty and safety listing.  
Ì A working smoke detector must be installed in the same room as this product.  
HOW YOUR STOVE WORKS  
Your King/Ashley stove utilizes a inclined auger fuel feed system that is operated by a microprocessor controlled digital  
circuit board. The digital circuit board allows the inclined auger fuel feed system to run in a timer-based, non-continuous  
cycle; this cycling allows the auger to run for a predetermined period of seconds. The auger pushes pellets up a chute  
located at the front/bottom of the hopper which in turn falls through another chute into the burnpot . As pellets enter the  
burn pot, outside air is drawn across the fuel and heated during the combustion process. This heated combustion air is  
then pulled through the heat exchanger by the exhaust blower, where it is used to heat air that is drawn into the heat  
exchanger system by the room air fan.  
Because a forced draft pressure is required for the combustion process inside your stove, it is extremely important that  
the exhaust system be properly installed and maintained. And, that when operating your stove, you make sure that the  
viewing door is properly sealed.  
Your stove’s heat output can vary from hi to low by adjusting the settings on the control panel (located on the lower right-  
hand side of the stove). The “HEAT RANGE” setting will vary the auger systems feed rate and the exhaust blower  
speed (i.e. combustion air). The “BLOWER SPEED” setting will adjust the room air fan speed (i.e. convection air).  
Each setting has a range of 1 to 9 (lowest to highest). Any combination of “HEAT RANGE” and “BLOWER SPEED”  
can be used during the operation of your stove.  
Your stove can run efficiently over extended periods of time and at different heat output levels as long as the fuel supply  
is uninterrupted and proper cleaning and maintenance is performed. (NOTE: Operating your stove on a high “HEAT  
RANGE” setting and a low “BLOWER SPEED” setting for extended periods of time may cause your stove to reach an  
over-temperature condition, in which case, the stove will automatically reduce the fuel feed rate and/or increase the  
room air fan speed. This is a safety precaution that has been designed into your stove and is not a malfunction)

Operation  
CONTROL PANEL  
Turning the stove OFF/ON, as well as adjustments for the fuel  
feed rate and room air fan speed are performed by pressing  
the appropriate button(s) on the control panel which is located  
on the lower left-hand side of your King/Ashley stove (see  
FIGURE 10).  
Pressing the “ON” button on the control panel will begin the  
start-up sequence for the stove. Fuel will begin to feed through  
the auger feed system and, once an adequate amount of fuel  
has been deposited into the burn pot, the auto-start igniter  
will ignite the fuel.  
Pressing the up/down arrow buttons beneath the “HEAT  
RANGE” and “BLOWER SPEED” will adjust the amount of  
fuel that is fed to the burnpot and the amount of room air drawn  
through the stove to be heated, respectively. Either value can  
be set from 1 to 9 (lowest to highest).  
FIGURE 10  
DIGITAL CONTROL PANEL  
Pressing the “OFF” button on the control panel will cause the stove to enter its shut-down sequence. The fuel feed  
system will stop pulling fuel from the hopper and, once the fire goes out and the stove cools down, the blowers will stop  
running.  
The “A”, “B”, and “C” buttons on the control panel are reserved for diagnostic use only. These controls are disabled by  
default when the unit is shipped from our factory.  
UNIT PREPARATION  
After carefully unpacking and reading the instructions for installing your stove, you will need to perform the following  
steps:  
1.)  
Attach the included spring handle to the door handle by screwing it on in a respective location.  
Attach the electrical cord to the back of the stove first; then plug it into a 110-volt outlet (an outlet surge protector is  
highly recommended).  
2.)  
PERFORMING A “DRY RUN”  
Perform a “dry run” on your stove prior to making the exhaust/inlet connections and starting your stove for the first time.  
1.)  
2.)  
3.)  
4.)  
Check that there is NO fuel in the hopper or burn-pot.  
Check that the viewing door is securely closed.  
Press the “ON” button on the control panel. This will start the auger and exhaust blower.  
Check that the auger and the exhaust blower are operating (the room air blower will not start at this time). DO NOT  
open the viewing door, the auto-start igniter will get very hot during this test. The stove will automatically shut down  
after approximately 23 minutes.

Operation  
START-UP PROCEDURE  
Never use gasoline, gasoline-type lantern fuel, kerosene, charcoal lighter fluid, or similar liquids to start or  
“freshen up” a fire in this stove. Keep all such liquids well away from the stove while it is in use.  
Ì
Verify that the hopper is clean and free of foreign matter.  
1.)  
2.)  
Verify that all of the required exhaust/inlet connections have been made in accordance with this manual and that the  
stove is plugged into an outlet (an outlet surge protector is highly recommended).  
Fill the hopper with wood pellets; do not allow any part of the bag or any other foreign material into the hopper, as this  
may jam the auger.  
3.)  
Ensure that all pellet matter is cleared from the hopper seating surface.  
Close the hopper lid.  
4.)  
5.)  
6.)  
Make sure that the viewing door is securely closed (the safety pressure switch will not allow the stove to feed fuel if  
there is no draft pressure inside the stove) .  
Press the “ON” button on the control pad and set the “HEAT SETTING” to your desired setting.  
7.)  
8.)  
The stove will begin to feed fuel and the auto-start igniter will ignite the fuel in approximately 3 minutes.  
Once a consistent flame has been established, you can adjust the “HEAT RANGE” and “BLOWER SPEED” on the  
control pad to your desired settings. (Note: The room air fan will not function until the heat exchanger in the stove  
reaches the factory preset temperature).  
First Fire: Adjust the “HEAT RANGE” and “BLOWER SPEED” to a “5” setting and allow the stove to  
operate in this manner for approximately three (3) hours (or more if necessary), allowing the stove to  
“cure out” as the paint and oils from the manufacturing process burn off. We recommend that you open  
doors and windows in your home during this process. Adjust setting to desired setting.  
SHUT DOWN PROCEDURE  
WARNING: Never shut down this unit by unplugging it from the power source.  
Press the “OFF” button on the control pad to put the stove in shut down mode. At this time, the red light above the pad  
will illuminate. Once this is done, the auger will stop feeding pellets, but the room air fan, exhaust blower, and bottom  
auger will continue to operate. When the internal temperature of the unit drops below the factory preset temperature,  
the room air fan and exhaust blower will cease to operate. The red light will then shut off and the unit will be completely  
shut down.  
The hotter the unit is during its operation, the longer it will take for the stove to complete the shut down cycle. If the stove  
stays on for more than 2 hours after pressing the “OFF” button and you are sure that the fire is out, the stove can be  
unplugged from the outlet. After approximately 10 seconds, the unit can be re-connected to the power source and the  
control board will be reset.

Operation  
DAILY OPERATION  
Ì
The hopper and stove top will be hot during operation; therefore, you should always use some type of hand  
protection when refueling your stove.  
Ì
Never place your hand near the auger while the stove is in operation.  
This unit should be filled when the hopper level drops below 3-inches.  
In the event of a power outage, the stove WILL NOT function. It is very important that unit be vented properly (with  
outside air), as the natural draft is needed to clear the smoke from the stove during a power outage. If the unit was “ON”  
when the power outage occurred, one of the following will take place:  
1.)  
If the stove is still warm, it will resume feeding fuel and continue to operate normally. If the fire has gone out, you will  
have to press the “OFF” button and then the “ON” button again to begin a new start-up sequence.  
2.)  
If the stove has cooled-off, it will reset to its “OFF” condition. At this point, you may press the “ON” button and the  
unit will begin a new start-up sequence.  
NOTE: The unit will also shut down in the event of an exhaust blower failure; if this is the case, the unit will not re-start  
and you must contact Customer Service at (800) 750-2723.  
SAFETY AND CONVENIENCE FEATURES  
Your King/Ashley incorporates a safety pressure switch that helps ensure that everything is in proper working order  
before feeding fuel to the burn pot. Because the stove works using an induced draft pressure, the stove will not continue  
to operate if the viewing door is left open; or if the combustion blower fails or the exhaust system is blocked.  
The temperature limit control will prevent your stove from operating at abnormally high temperatures. Should the  
stove temperature begin to approach the factory pre-set limit, the temperature limit control will automatically slow down  
the auger feed rate until the temperature returns to a normal condition. Even though the heater will operate on setting  
“9” (HI), we recommend to operate your heater on this setting for only a short period of time. (1 hour etc.)  
Your King/Ashley stove also includes an auto-start igniter as a standard feature. The use of other fire starter materials  
(wood chips, starter gel, etc.) is not necessary. By simply pressing the “ON” button on the digital control panel, your  
stove will begin to feed fuel and automatically start within 5 minutes.  
Maintenance  
Ì Failure to clean and maintain this unit as indicated can result in poor performance and safety hazards.  
Ì Unplug your stove’s electrical cord prior to removing the back panel or opening the exhaust system for any  
inspection, cleaning, or maintenance work.  
Ì Never perform any inspections, cleaning, or maintenance on a hot stove.  
Ì Do not operate stove with broken glass , leakage of flue gas may result.  
EXHAUST SYSTEM  
The by products of combustion contain small particles of fly ash. Fly ash will collect in the exhaust venting system and  
restrict the flow of flue gases. Incomplete combustion, such as during startup, shutdown, or incorrect operation of the  
stove will lead to soot formation which will collect in the exhaust system. Therefore, it is important that the exhaust  
system be inspected and cleaned at least monthly during the burning season.  
Check the clean out tees periodically to determine the required cleaning schedule. 3 or 4-inch chimney brushes are  
available for chimney cleaning. If the exhaust system or outside air pipes have screens on them, frequently clean the  
screen. A plugged screen will shut off combustion air and cause a fire to die or burn poorly.

Maintenance  
INTERIOR CHAMBERS  
Periodically remove and clean the burnpot and the area inside the burnpot housing. In particular it is advisable to clean  
out the holes in the burnpot to remove any build up that may prevent air from moving through the burn pot freely.  
If a vacuum is used to clean your stove, we suggest using a vacuum designed for ash removal. Some regular vacuum  
cleaner (i.e. shop vacs) may leak ash into the room.  
ASH DISPOSAL  
Ashes should be placed in a metal container with a tight fitting lid. The closed container of ashes should be placed on  
a noncombustible floor or on the ground, well away from all combustible materials, pending final disposal. If the ashes  
are disposed of by burial in soil or otherwise locally dispersed, they should be retained in the closed container until all  
cinders have been thoroughly cooled.  
CHECK AND CLEAN THE HOPPER  
Check the hopper periodically to determine if there is any sawdust or pellets that are sticking to the hopper surface.  
Clean as needed.  
MAIN DOOR GASKETS  
Inspect the main door and glass window gaskets periodically. The main door may need to be removed to have frayed,  
broken, or compacted gaskets replaced by your Authorized “King/Ashley” Dealer.  
FAN MOTORS  
Clean the air holes on the motors of both the exhaust and room air fans annually. Remove the exhaust blower from the  
exhaust duct and clean out the internal fan blades as part of your fall start-up.  
PAINTED SURFACES  
Painted surfaces may be wiped down with a damp cloth. If scratches appear, or you wish to renew your paint, contact  
your Authorized “King/AshleyDealer to obtain a can of suitable high-temperature paint.  
GLASS  
We recommend using a high quality glass cleaner. Should a build up of creosote or carbon accumulate, you may wish  
to use 000 steel wool and water to clean the glass. In the event you need to replace the glass, only high temperature  
ceramic glass of the correct size and thickness may be used. Contact your Authorized “King/AshleyDealer to obtain  
this glass.  
FALL START UP  
Prior to starting the first fire of the heating season, check the outside area around the exhaust and air intake systems for  
obstructions. Clean and remove any fly ash from the exhaust venting system. Clean any screens on the exhaust  
system and on the outside air intake pipe. Turn all of the controls on and make sure that they are working properly. This  
is also a good time to give the entire stove a good cleaning throughout.  
SPRING SHUTDOWN  
After the last burn in the spring, remove any remaining pellets from the hopper and the auger feed system. Scoop out  
the pellets and then run the auger until the hopper is empty and pellets stop flowing (this can be done by pressing the  
“ON” button with the viewing door open). Vacuum out the hopper. Thoroughly clean the burnpot, and firebox. It may be  
desirable to spray the inside of the cleaned hopper with an aerosol silicone spray if your stove is in a high humidity area.  
The exhaust system should be thoroughly cleaned.  
YEARLY SERVICING  
A yearly servicing and cleaning by your Authorized “King/Ashley” Dealer is recommended. A fee may be charged for  
this service.

Trouble Shooting  
Ì Disconnect the power cord before performing any maintenance! NOTE: Turning the ON/OFF Switch to  
”OFF” does not disconnect all power to the electrical components of the stove.  
Ì Never try to repair or replace any part of the stove unless instructions for doing so are given in this manual.  
All other work should be done by a trained technician.  
PROBLEM  
CAUSE: To rich air/fuel mixture  
Orange, lazy flame_excessive fuel Clean out the burnpot and burnpot housing  
build-up in the burnpot  
Make sure that the viewing door is closed and sealed properly. If not,  
adjust door catch and/or replace door gaskets.  
Check that all outside connections are clear of any obstructions.  
Check the exhaust system; clean as needed.  
PROBLEM  
CAUSE: Burnpot burns out of fuel  
Fire goes out or stove shuts down.  
Hopper is empty, refill the hopper.  
Loss of draft pressure. Make sure that the viewing door is closed and  
sealed properly. If not, adjust door catch and/or replace door gaskets.  
Check that all outside connections are clear of any obstructions. Check  
the exhaust system; clean as needed.  
Check that the pressure switch connection to the firebox is free of ash or  
clear of obstructions.  
Auger system is jammed or there is a “bridging” of the fuel in the hopper,  
preventing fuel from flowing into the auger feed system.  
PROBLEM  
CAUSE: Auto-Start Igniter fails to ignite the fuel in the burn pot.  
Stove does not start a fire when the Turn the stove “OFF”. Clear the unburnt fuel from the burnpot and try  
“ON” button is pushed  
again.  
Check the pellet quality. Repplace if moist, wet, or dirty.  
Loss of draft pressure. Make sure that the viewing door is closed and  
sealed properly. If not, adjust door catch and/or replace door gaskets.  
Check that all outside connections are clear of any obstructions. Check  
the exhaust system; clean as needed.  
Check that the auto-start igniter is not blocked with ash or soot. (The  
igniter is located behind the burnpot on the back wall of the firebox.)  
Check that the pressure switch connection to the firebox is free of ash or  
clear of obstructions.  
The auto-start igniter gets “red hot” during start-up. If you can not visibly  
see the igniter glowing during start-up, then the igniter may need to be  
replaced or there is a problem with the electrical control system.
