8. Fasten the conduit to the ash base with the clamps

provided.

Floor Protection:

The striped area indicates the minimum required ﬂoor protec-

tion area if the boiler is going to be placed on a combustible

ﬂoor. It requires 40” X 55”(US) or 42” X 55”(CAN) of non

combustible ﬂoor protection as shown. 16”(US) or 18”(CAN)

of the ﬂoor protection must be in front of the ﬁrebox door

as shown. Floor protection must be a minimum of 26 gauge

sheet metal. Floor protection must also be provided under any

horizontal run of vent pipe equal to the outside diameter of the

venting plus 2” to each side.

Design:

The ﬁrst thing that needs to be done is deciding where and

how the boiler will be installed.

Things that need to be taken into consideration are the

intended use of the boiler for example, is the boiler going to

be used as your primary heating system or is it going to be

used as a secondary or backup heating system. If it is to be

used in conjunction with an existing oil or gas boiler system

will it be piped in parallel or in series? The answers to these

and other questions can be determined by talking to your

certiﬁed dealer or a qualiﬁed HVAC or plumbing contrac-

tor. This will ensure that the boiler is installed and piped to

accommodate your needs and expectations.

Example: 4” type “L” or “PL” vent pipe has an outside diam-

eter of 4-1/2” + 2” on each side equals a protected ﬂoor area

of 8-1/2” wide underneath the horizontal run.

Consideration must be given to the venting as well as

electrical and clearance requirements. (Clearances must be

maintained to combustibles and also for service)

Make sure fans are not used in the fuel storage area, unless

they are installed so as not to create a negative pressure in the

room where the solid fuel burning appliance is located.

Requirements for Terminating the Venting

WARNING: Venting terminals must not be recessed into

a wall or siding.

NOTE: Only PL vent pipe wall pass-throughs and ﬁre

stops should be used when venting through combustible

materials.

NOTE: Always take into consideration the effect the

prevailing wind direction or other wind currents will

cause with ﬂyash and /or smoke when placing the ter-

mination.

In addition, the following must be observed:

A. The clearance above grade must be a minimum of

18”.¹

B. The clearance to a window or door that may be

opened must be a minimum of 48” to the side, 48”

below the window/door, and 12” above the window/

door.¹

C. A 12” clearance to a permanently closed window is

recommended to prevent condensation on the window.

D. The vertical clearance to a ventilated sofﬁt located

above the terminal within a horizontal distance of 2 feet

(60 cm) from the center-line of the terminal must be a

minimum of 18”.

from the horizontal center-line of the regulator.¹

I. The clearance to service regulator vent outlet must be

a minimum of 6 feet.¹

J. The clearance to a non-mechanical air supply inlet

to the building or the combustion air inlet to any other

appliance must be a minimum of 48”.¹

K. The clearance to a mechanical air supply inlet must

be a minimum of 10 feet.¹

L. The clearance above a paved sidewalk or a paved

driveway located on public property must be a minimum

of 7 feet.^1,2

M. The clearance under a veranda, porch, deck or

balcony must be a minimum of 12 inches.^1,3(B Also

applies)

NOTE: The clearance to vegetation and other exterior

combustibles such as mulch is 36” as measured from the

center of the outlet or cap. This 36” radius continues to

grade or a minimum of 7 feet below the outlet.

¹Certain Canadian and or Local codes or regulations

may require different clearances.

²A vent shall not terminate directly above a side-

walk or paved driveway which is located between two

single family dwellings and serves both dwellings.

³Only permitted if veranda, porch, deck, or balcony is

fully open on a minimum of 2 sides beneath the ﬂoor.

E. The clearance to an unventilated sofﬁt must be a

minimum of 12”.

F. The clearance to an outside corner is 11” from center

of pipe.

G. The clearance to an inside corner is 12”.

H. A vent must not be installed within 3 feet (90 cm)

NOTE: Where passage through a wall, or

partition of combustible construction is desired,

the installation shall conform to CAN/CSA-B365.

Avoiding Smoke and Odors - Negative Pressure,

Shut-down and Electrical Power Failure.

To reduce the probability of reverse drafting dur-

ing shut-down conditions, Hearth & Home Tech-

nologies strongly recommends:

• Installing the pellet vent with a minimum vertical

run of 5 feet. Preferably terminating above the roof

line.

To reduce the probability of back-drafting or burn

back in the pellet boiler during a power failure,

it must be able to draft naturally without exhaust

blower operation. Negative pressure in the house will

resist this natural draft if not accounted for during in-

stallation. Heat rises in a house, and leaks out at upper

levels. This air must be replaced with air from outside

the dwelling, which normally ﬂows into lower levels.

Vents and chimneys into basements and lower levels

can become the conduit for return air and reverse un-

der these conditions.

Hearth & Home Technologies strongly recommends

the use of outside air in all pellet boiler installa-

tions, especially those on lower level and main ﬂoor

locations. Per national building codes, consideration

must be given to combustion air supply to all combus-

tion appliances. Failure to supply adequate combustion

air for all appliance demands may lead to back-draft-

ing of those and other appliances within the home.

• Installing the outside air intake at least four feet

below the vent termination.

To prevent soot damage to exterior walls, and to pre-

vent re-entry of soot or ash into the house:

• Maintain speciﬁed clearances to windows, doors

and air inlets, including air conditioners.

• Vents should not be placed below ventilated sofﬁts.

Run the vent above the roof.

• Avoid venting into alcove locations.

• Vents should not terminate under overhangs, decks

or onto covered porches.

• Maintain minimum clearance of 12” from the vent

termination to the exterior wall. Extending this dis-

tance may be required if visual accumulation occurs.

Venting

venting

Venting

Use 4” pellet vent pipe only.

A combustion blower is used to extract the combustion

gases from the ﬁrebox. This creates a negative pressure in

the ﬁrebox and a positive pressure in the venting system

as shown in Fig. 4. The longer the vent pipe and more

elbows used in the system, the greater the ﬂow resistance.

Because of these facts we recommend using as few elbows

as possible and 30 feet or less of vent pipe. The maximum

horizontal run should not exceed 18 feet.

4” Type “L” or

“PL” Vent pipe

Be sure to use wall and ceiling pass through ﬁttings

(which are approved for pellet vent pipe ) when going

through combustible materials. Be sure to use a starting

collar to attach the venting system to the stove. The start-

ing collar must be sealed to the stove ﬂue collar with

high temp silicone caulking or aluminum tape, and

screwed into the stove ﬂue collar at least three (3) places.

Fig. 5

This is the minimum venting conﬁguration.

The minimum vent conﬁguration is a 90^oor Tee on

a starter collar and a 24” length horizontal through an

exterior wall. A cap on the end should direct the ﬂue

gasses down and away from the structure. See Fig. 5.

The maximum horizontal length is 18 feet. The

minimum termination height above the exterior grade

is 18”. The maximum total length of any conﬁguration

is 30 feet*.

* ( see venting graph on page 9 for exceptions )

NOTE: Cleanout Tee’s should always be used on the

transitions to horizontal pipe to allow easy access for

cleaning.

The venting graph allows for one(1) 90 deg. or Tee

ﬁtting in any conﬁguration.

If more 90’s, T’s, or 45’s are needed, the total length

must be adjusted to allow for the added restriction.

Up to four (4) additional 90’s, Tee’s, or equivalent 45’s

can be added as long as the overall length is adjusted in

accordance with the values listed below.

Fig. 4

Vent Pipe

4” pellet vent pipe (also known as “PL” vent) is con-

structed of two layers with air space between the layers.

This air space acts as an insulator and reduces the outside

surface temperature to allow a minimum clearance to

combustibles as low as 1 inch. In Canada the minimum

clearance to combustibles is 3 inches.

The sections of pipe lock together to form an air tight

seal in most cases; however, in some cases a perfect seal

is not achieved. For this reason and the fact that the boiler

operates with a positive vent pressure, we specify that all

joints within the structure should also be sealed with

silicone.

( See the venting graph on page 10.)

Each Vertical ---- 90 deg. or T subtract 2.5 feet

Each Vertical ---- 45 deg.

Each Horizontal - 90 deg. or T subtract 5.0 feet

Each Horizontal - 45 deg. subtract 2.5 feet

subtract 1.5 feet

Any exterior venting (vent pipe exposed to outside

ambient temperatures) should be kept to a minimum,

due to potential condensation problems.

This is especially important in high humidity cold

weather climates, such as maritime areas, lake shores,

and low river valleys.

NOTE:Use only 4” diameter approved PELLET

venting system. Be sure to inspect and clean exhaust

venting system frequently.

Creosote - Formation and Need for Removal - When wood is burned slowly, it produces tar and other organic vapors,

which combine with expelled moisture to form creosote. The creosote vapors condense in the relatively cool chimney ﬂue

of a slow-burning ﬁre. As a result, creosote residue accumulates on the ﬂue lining. When ignited, this creosote makes an

extremely hot ﬁre. The pellet vent pipe should be inspected at least twice monthly during the heating season to determine

if a creosote buildup has occurred. If creosote has accumulated it should be removed to reduce the risk of a chimney ﬁre.

Guidance on minimizing creosote formation and the need for periodic creosote removal: The chimney should be

inspected during the heating season to determine if a creosote build-up has occurred. If a signiﬁcant layer of creosote has

accumulated (3mm or more) it should be removed to reduce the risk of a chimney ﬁre.

Outside Air

To install outside air, use 2 3/4” I.D.galvanized

steel ﬂex pipe, part # 2-00-08544 ( 12’6” length) or part

# 2-00-08545 ( 25’length) See Fig. 6. There is a break-

away hole on the rear panel which must be removed

before connecting the ﬂex pipe. See Fig. 7.

When the appliance is side wall vented: The air

intake is best located on the same exterior wall as the

exhaust vent outlet, and located lower on the wall than

the vent outlet.

When the appliance is roof vented: The air intake

is best located on the exterior wall oriented toward the

prevailing wind direction during the heating season.

Never terminate the outside air above the vent pipe

outlet. The maximum length of this pipe is 20 feet. Inlet

cover part number 1-10-09542 should be used to keep

birds, rodents etc.out of the inlet pipe. See Fig.6.

NOTE: The inlet cover should not be placed in an

area where drifting of snow or ice will build up, block-

ing the intake air supply.

Over heat Safety zone

OverHeat Safety Zone (Dump Zone): STRONGLY RECOMMENDED in all installations.

When the pellet boiler is operating at High burn, and all demand from the heating system stops, the control

will reduce the feed rate and shut down completely as necessary. This may take several minutes, and the remain-

ing heat may cause the water temperature to continue to rise. If the temperature gets too high, the OVERHEAT

SAFETY ZONE light on the control (see page 23) will illuminate, and the DARK BLUE circuit in the junction box

is energized(see wiring diagram). This circuit will ﬂow 120V to operate a circulator pump installed to ﬂow to the

overheat dump zone established in the original installation plan. If opening a zone valve is the chosen method of

dumping the excess heat, a voltage reduction relay will most likely be needed. If the water temperature continues

to rise to the risk of boiling point, the feed system will stop and the boiler will shut-down. A manual reset will then

be required to operate the boiler. Without a dump zone in place, the excess temperature will build pressure to the

point of opening the relief valve, or with the atmospheric conversion it will allow the water to boil and over-ﬂow

the atmospheric tank. Both scenarios may create water damage and/or slip hazard.

The boiling temperature of water varies at different altitudes and atmospheric pressures. Therefore, at eleva-

tions above 3000 feet, and when using the atmospheric conversion, circuit board dipswitch #6 must be in the “ON”

position.

Draft Test Procedure

After the venting is completed, the ﬁrebox low draft

will need to be checked and possibly adjusted. After

removing the 3/8” bolt from the draft hole shown in Fig.

9, insert the draft meter tube. The appliance doors and

hopper lid must be latched during this test. (It is recom-

mended that the draft meter have a scale of 0 to 1” WC.)

Turn the feed adjuster to “Test”. this will start the

combustion blower and allow you to check and record

the High Draft ______ - IWC date _______ The

maximum draft must not exceed -.85” W.C. Some form

of vent restrictor may be needed. (There is no control

board adjustment for the High Draft)

Firebox Door

Draft Bolt Location

Air Wash Slot

After the ﬁrst 60 seconds the “Test” mode lowers the

combustion blower voltage to the Low Burn voltage.

During this lowered voltage cycle the Low Burn Draft

must be checked and adjusted if necessary. The recom-

mended low draft setting should be between -.25 & -.35

IWC. Depending on the amount of vertical rise, it may

not be possible to get a low draft reading in this range.

In this case, a maximum low draft of -.55 is acceptable.

The adjustment screw is through the small hole to the

right of the Igniter Light. See Fig. 10. Adjusted Low

Draft is __________ -IWC.

Viewing Window

“Test”

Don’t forget to turn the feed adjuster off of “Test”.

Do not operate if the high draft exceeds -.85” W.C.

Excessive draft readings may be due to restriction in

the combustion air supply. Check for obstructions.

Fuel Speciﬁcations

Fuel and Fuel Storage

Performance

Pellet fuel quality can ﬂuctuate from manufacturer to

manufacturer, and even from bag to bag.

Hearth & Home Technologies recommends using only

fuel that is certiﬁed by the Pellet Fuels Institute (PFI).

•

Higher ash content requires more frequent mainte-

nance.

“Premium” grade pellets will produce the highest

heat output.

Burning pellets longer than 1-1/2 inches (38mm)

can cause inconsistent feeding and/or ignition.

Fuel Material

•

Made from sawdust and/or other wood by-products

Source material typically determines ash content

We recommend that you buy fuel in multi-ton lots

whenever possible. However, we do recommend try-

ing different brands prior to purchasing multi-ton lots,

to ensure your satisfaction.

Higher Ash Content Material

•

Hardwoods with high mineral content

Bark and leaves as source material

“Standard” grade pellets, corn and other biomass

CAUTION! Tested and approved for use with wood

pellets ONLY. Burning of any other fuel will void your

warranty.

Lower Ash Content Material

•

Softwood; pine, ﬁr, etc.

Materials with lower mineral content

“Premium” grade pellets

When changing from “Premium” grade pellets to a

“Standard” or “Economy” grade fuel, the FEED AD-

JUSTER will likely need adjusted to a lower setting.

When under maximum demand, ensure there is no

unburned fuel being pushed into the ash pan.

CAUTION! Do not burn fuel that contains an additive;

(such as soybean oil)

•

May cause hopper ﬁre

Damage to product may result

Storage

•

Wood pellets should be left in their original sealed

bag until ready to use, to prevent moisture.

Do not store fuel within the speciﬁed clearance ar-

eas, or in a location that will interfere with routine

cleaning and maintenance procedures.

Read the list of ingredients on the packaging. If you are

buying wood pellets, the only ingredient listed should be

wood ﬁber or sawdust.

•

Clinkers

Minerals and other non-combustible materials, like sand,

will turn into a hard glass-like substance when heated.

Trees from different areas will vary in mineral content.

For this reason, some fuels will produce more clinkers

than others.

Moisture

CAuTION

Always burn dry fuel. Burning fuel with high moisture

content takes energy to dry and tends to cool the appli-

ance thus, robbing heat from your home. Damp pellet

fuel could turn back into sawdust which does not ﬂow

properly through the feed system.

Tested and approved for use with wood pellets

ONLY. Burning of any other fuel will void your

warranty.

Size

NOTICE

•

Pellets are either 1/4 inch or 5/16 inch (6-8mm) in

diameter

Hearth & Home Technologies is not responsible for

stove performance or extra maintenance required

as a result of using fuel with higher ash or mineral

content.

•

Length should be no more than 1-1/2 inches (38mm)

Pellet length can vary from lot to lot from the same

Operation

Setting The Boiler Temperature

Without the Outdoor Air Temperature Sensor

Installed

To set the maximum boiler water temperature, sim-

ply turn the Max. Temp. water temperature dial to the

desired setting. The control and the boiler will then

perform to achieve and maintain the set temperature.

The Min. Temp. Knob is the boiler water tempera-

ture minimum, or the lowest temperature the water

will go before the unit re-starts. Turning the knob fully

counter-clockwise is the “OFF” position, while turn-

ing the knob clockwise, past the 140 degree marking,

is the “ON” position..

With The Outdoor Air Temp - Sensor Installed

Maximum boiler temp setting is as described above.

The MIN. TEMP. knob in addition to being the

mode setting (on or off) now also has the function of

setting the minimum boiler water temperature. This

would be the lowest boiler water temperature that you

want to have based on the following factors.

1.) Outdoor Air Temperature (OAT)

WATER TEMPERATURE

2.) Domestic Hot Water Use

a.) Hot Water Coil Option

b.) Indirect Hot Water Storage

3.) Overall Volume of the Heating System

MAX. TEMP.

Control Board Operation

MIN. TEMP.

The boiler is designed to withstand lower return water

temperatures however, extended return temperatures below

140 degrees F can cause condensation in the secondary

ash chamber area and also in the venting system, which

could cause damage in these areas.

Aquastat Sensor - This sensor is located in the aqua-

stat well on the top of the water jacket. This sensor

along with the outdoor air sensor is what the control

board uses to regulate the feed rate based on these two

observed conditions. (Boiler Temp. & Outdoor Air

Temperature)

NOTE:

Outdoor Air Temp. Sensor (OAT) - This sensor is

located outside the building (on the north side of the

house and out of direct sunlight). The Outdoor Air

Sensor is used to perform hot water reset based on out-

door air temperatures.

When the OAT sensor is installed, at 20° F. or below

(outside temperature), the boiler will operate at the

temperature set on the MAX. TEMP. knob. The boiler

water temperature will decrease by 1 degree F. for

every 1 degree F. in temperature rise (above 20°) of

the outdoor air.

If the system is run at the lower temperature settings, con-

ditions of the ﬁrebox, boiler tubes, secondary ash chamber

and venting should be monitored closely. If conditions show

excess condensation, the boiler water minimum tempera-

ture will need to be increased until condensation does not

occur. You should also consider some form of tempering of

the return water system. Discuss this with your plumber.

Operation

Starting A Fire Automatically

1. Turn Mode Selector to “OFF”.

This resets the control in addition to turning

it off.

2. Clean Burnpot with scraper, if necessary.

This is usually a weekly maintenance proce-

dure. Cleaning the burn pot with the scraper with

a small amount of new fuel in the bottom is not a

problem. First, scrape the ashes on the front of the

burn pot into the ash pan. Then scrape the hole grid

surface downward into the burn pot. When the stove

is ignited these scrapings will be pushed out by the

feeder.

The illustration at left shows the hopper swing plate

open for easy access to the burn pot. The burn pot

can also be reached through the ﬁrebox door.

NOTE: To minimize the amount of stress placed

on the hopper swing plate hinges, opening of the

hopper swing plate should be done with the least

amount of fuel in the hopper as possible.

Scrape burnpot to remove any carbon

build-up that may have occurred

3. Fill Hopper with pellets.

When ﬁlling the hopper check for excessive ﬁnes

in the bottom of the hopper. Fines are small pieces of

broken pellets (sawdust). Fines do not ﬂow easily and

often build up on the hopper funnel bottom angles.

These ﬁnes can be pushed into the feeder opening

and then ﬁll the hopper with pellets. As the system

works, they will be burned.

Operation

4. If Starting After an Empty Hopper, Turn Feed

Adjuster to “TEST” (for one 60 second cycle).

This will feed pellets into the auger tube and also

allow you to check the motors for operation. NOTE:

The auger motor will not operate with any of the

doors open.

5. Turn Feed Adjuster to #4.

If this is your ﬁrst ﬁre or you are trying differ-

ent pellets, set the feed adjuster to #4, This is an

average number for most pellets and may need to

be adjusted for your particular fuel. After you know

a feed rate setting that works well for your applica-

tion, use that setting.

NOTE: You know your feed rate is too high when:

The overheat safety feature is energized each time

the heating zone demand turns off during a high burn.

OR, If unburned or partially burned pellets are found

in the ash pan.(this may also be an indication of a

burn pot in need of scraping.)

6. Flip the Igniter Switch up into the “AUTO”

position.

7. Turn the MAX. TEMP. Dial on the control

board to the desired temperature. This setting must

always be at least 5° F. higher than the MIN. TEMP.

setting.

Operation

7. Open hopper swing plate as shown in Fig. 13 (See

“NOTE” on page 26.)

8. Turn the MIN. TEMP. Dial on the control board

to the desired Minimum temperature. This will start the

lighting process if the temperature at the aquastat sensor

is approximately 5° F. less than the set temperature on

the MAX TEMP. dial.

This is more than just an automatic ignition pellet

boiler. The automatic system will allow the ﬁre size to

be adjusted to match the heating needs and even put the

ﬁre out if necessary. If heat is needed after the ﬁre is out,

the boiler will automatically re-ignite and adjust the ﬁre

size to match the heating need.

Fig. 13

8. Fill burnpot with pellets as shown.

See Fig. 14. Only ﬁll level with the front edge.

( ------- DO NOT OVERFILL ------- )

9. Fill hopper with pellets and remove ashes as

required.

Type of Fuel

Use pelletized wood only. The lower the ash content of

the pellets the less cleaning that will be needed of the

heat exchanger surfaces. The cleaner these surfaces are

kept, the more efﬁcient the boiler will be.

NOTE: Do not burn garbage, gasoline, naphtha, engine

oil, or other inappropriate materials in this unit.

Store pellets in the manufacturer’s wrapping until

needed to prevent pellets from absorbing moisture.

Do not store fuel within the appliance installation

clearances, or within the space required for fueling,

ash removal, and other routine maintenance

operations.

Lighting A Fire Manually

Lighting the ﬁre manually will not be necessary unless

the igniter system fails.

Follow steps 1 through 5 of the instructions for

automatic lighting.

6. Flip the Igniter Switch Down into the “MANUAL-

LIGHT” position. See Fig. 12.

Fig. 14

9. Have matches or other ignition source ready.

10. Turn Mode Selector to desired MIN TEMP setting.

This will start the combustion blower and allow the

ESP to control the ﬁre in relation to the MAX TEMP

Dial setting. (The MAX TEMP dial setting must always

be set above the MIN TEMP setting) Once the ﬁre is

well established the MAX TEMP dial can remain on

any temperature setting desired.

NOTE: When the Switch is set to Manual ignite position

the boiler will function as in auto ignite except the ﬁre will

not be allowed to go out. It will only be allowed to go to a

minimum burn rate between the times the aquastat is calling

for heat. This rate is about 1.1 pound of fuel per hour. If used

in the Manual ignite mode, be sure there is an overheat dump

zone in place. Note that if the dump zone does not provide

sufﬁcient cooling, and the water temperature continues rising,

the feed motor will be forced to shut off. Because the unit is

in Manual Ignite mode, it will not re-ignite when the water

temperature cools below the control settings.

Operation

11. Apply starting gel as shown in Fig.15

12. Light The Starting Gel With A Match.

Fig. 15

NOTE: Stirring the starting gel into the pellets usually

allows the ﬁre to become established quicker.

13. Close The Doors

The ﬁre will light and the control will adjust the ﬁre

to the proper level according to the MAX TEMP dial

setting.

CAUTION: A vapor ﬂash could occur if too much

time is allowed to pass before lighting the starting gel.

NOTICE: when burning the boiler in the

manual ignition mode, there must be an

overheat dump zone incorporated into the

plumbing system.

CAUTION: Care must be taken not to get starting gel

on your hands or clothing. Serious burns could occur

during the lighting process.

CAUTION: Never try to apply more starting gel to an

already burning ﬁre, or a ﬁre with smoldering pellets.

If heating demand stops during manual operation, the

control will take the unit to low burn. If no heat is used

during this time, the water temperature will continue to

rise. When the temperature gets too high, the feeder will

be turned off and the ﬁre will go out. This will require a

manual re-start of the system. (see page 23 “7 Blinks”)

Solid-fuel burning appliances need to be cleaned

frequently because soot, creosote, and ash may accu-

mulate. If you suspect a chimney/vent pipe ﬁre do

the following:

1. Call the ﬁre department.

2. Remove fuel from the burn pot using the burnpot

scraping tool to scrape the pellets into the ash pan.

3. Remove the ash pan from the unit and take outside.

Do not place ash pan on a combustible material.

4. Turn off circuit breaker at unit.

5. Do not use the unit until a qualiﬁed person has in-

spected your appliance and venting.

maintenance

Burnpot Cleaning:

The burnpot should be cleaned no less than once a week.

For best operation the burnpot should be cleaned every time

the hopper is ﬁlled with pellets. The ﬁre does not have to be

out to scrape the burnpot although it is recommended the

boiler be on minimum burn at the time of cleaning.

Note: Scraping can be done while in operation if per-

formed through the ﬁrebox door opening. See Fig. 17

Use the ﬂat end of the scraper provided to scrape down

over the holed surface of the burnpot grate. See Fig. 18. It

is not necessary to clean out the scrapings from this clean-

ing because they will be pushed out the next time the auger

operates.

Note: Make a special effort to scrape the bottom inside

corners of the burnpot where the auger tube enters the

burnpot. Carbon deposits can build up over time in this

area that may cause a restriction to the ﬂow of pellets into

the burnpot.

Note: An old long shank screwdriver with the end sharp-

ened is an ideal aid in the removal of these deposits.

Scrape the burnpot to remove any carbon

deposits which may have formed.

Scraping can be done while the boiler

is in operation, accessed through the

ﬁrebox door opening.

Fig. 17

Fig. 18

Cleaning the Burnpot Air Chamber:

This area only needs to be cleaned twice a heating sea-

son, unless excessive buildup is noticed during scheduled

cleanings.

There is a cover on the front of the burnpot to gain access

to the air chamber. The cover is held into place by two thumb

screws. Loosen the thumb screws and remove the cover. See

Fig. 19. The air chamber can be cleaned of any ash that has

fallen through the holes during operation and cleaning.Also

at this time, remove the feeder assembly cover and remove

any ﬁnes that may have accumulated.

cleaned at least once a year.

To remove the feeder cover:

• Loosen the 5/16” wing nut.

• Slide the cover off of the threaded stud and lift upward.

• Inspect and clean the inner chamber if necessary. See Fig. 20.

• Reinstall the cover making certain it is centered on the

feeder body and hand-tighten the wing nut.

Disposal of Ashes

WARNING! RISK OF FIRE!

Ash, soot or creosote build-up may cause

overheating or ﬁre.

Routine cleaning of heat exchangers and

venting is required.

Ashes should be placed in a steel container with a tight

ﬁtting lid. The closed container of ashes should be moved

outdoors immediately and placed on a non-combustible

ﬂoor or on the ground, well away from all combustible

materials, pending ﬁnal disposal. If ashes are disposed

of by burial in soil or otherwise locally dispersed, they

should be retained in the closed container until all cinders

have thoroughly cooled. Other waste shall not be placed

in this container.

•

Ash Removal

It is recommended to remove the ashes when the boiler

is not in operation. This lessens the chances of coming in

contact with hot surfaces. Ashes can be removed while

in operation but, extra care must be taken.

Soot and Flyash: Formation and Need for

Removal

Open Ash Door

The products of combustion will contain small particles

of ﬂyash. The ﬂyash will collect in the exhaust venting

system and restrict the ﬂow of the ﬂue gases. Incomplete

combustion, such as occurs during startup, shutdown,

or incorrect operation of the room heater will lead to

some soot formation which will collect in the exhaust

venting system. The exhaust venting system should be

inspected at least twice monthly to determine if cleaning

is necessary. Pay particular attention to screening in the

vent cap. The screen, if present, will accumulate with

ashes rather quickly.

Lift the latch and open the door as shown in ﬁg. 21.

NOTE: Keep hopper lid, hopper swing plate, ﬁrebox

door and ash pan door closed during operation and

maintain all seals in good condition.

Remove Ash Pan

Always wear gloves to remove ash pan. Grab the ash

pan by the ﬁnger hold and pull it out of the boiler. Lift

the ash pan by the ﬁnger hold and use it for carrying the

ash pan. Close the ash door before disposing the ashes.

Cleaning

-Open the ash door and remove the ash pan. Dispose

of any ash that has accumulated in the ash pan as well

as any ﬂy ash from within the ash pan area.

-Remove the (4) thumbscrews on the secondary

ash chamber access plate and remove it to access the

secondary ash chamber. Remove all ﬂy ash from this

area. This process should be done as needed.

This cleaning should be done after each ton of pellets

used. The frequency of this cleaning will be directly

related to the quality and the ash content of the pel-

lets being used. Keep in mind that the cleaner the heat

exchanger surface is kept, the higher the heat transfer

efﬁciency will be.

Due to it’s ease of restarting it is recommended that the

boiler be OFF and COOL before cleaning.

-Inspect all sealing gaskets to ensure a proper seal

and re-install all components removed for cleaning.

Start by actuating the (3) heat exchanger cleanout rods

by pulling and pushing these rods vigorously several

times. This action will remove any ﬂy ash built up on the

heat exchanger tubes. This can also be done at any time

during the operation of the boiler to maintain higher ef-

ﬁciencies. Make sure that these rods are pushed in when

cleaning is completed.

CAUTION: Cleanout of the heat exchanger, ﬂue

pipe, chimney, and combustion blower fan housing,

is especially important at the end of the heating

season to minimize corrosion during the summer

months, caused by accumulated ash.

Cleaning Steps

-Open the hopper swing plate to access burnpot and

also the ﬁrebox. With a wisp brush, wire brush, stiff

bristled paint brush or a soot vac, clean the ﬁrebox walls

and any ﬂy ash that has accumulated on the ledges of the

burnpot, or burnpot opening.At this time you can scrape

and clean the burnpot and ﬁnes cleanout area.

-Open ﬁrebox door and vacuum ash from ledges and

ash deﬂector.You can also clean the ﬁrebox door viewing

glass using a typical glass cleaner and soft cloth.

NOTE: To minimize the amount of stress placed on

the hopper swing plate hinges, opening of the hopper

swing plate should be done with the least amount of

fuel in the hopper as possible.

maintenance

The boiler MUST be OFF and COOL before you

should attempt to clean the combustion blower.

The wire to the combustion blower doesn’t need to be

disconnected during the cleaning process.

Loosen the three (3) thumb screws about 4 turns each.

See Fig. 23. Hold the motor head with one hand and the

blower plate handle with the other hand. Pull outward

on the plate handle until the complete unit comes loose.

Now rotate the plate counter-clockwise about 1/8 turn.

This will allow the complete assembly to be removed

from the blower chamber.

Latch

Fig. 22

Clean the blower fan blades and the blower plate

sealing overlap. See Fig. 24.

NOTE: Be careful not to bend the fan blades, this will

throw the fan blade out of balance or it may rub the inner

chamber, which may affect the performance of the boiler.

Any horizontal and vertical ﬂue pipe directly above the unit

should be cleaned at this time

Exhaust Probe

Combustion

Blower Motor

NOTE: The horizontal ﬂue pipe directly above the boiler

is the ﬁrst place ﬂy ash will settle, due to the slowing of ﬂue

gas velocity through horizontal pipe. Cleaning of horizon-

tal venting pipes is very important to the efﬁciency of this

boiler.

Thumb Screws (3 Total)

Fig. 23

Clean the ﬂue outlet throat as well as the inner chamber

of the ﬂue tunnel (this is the hole that goes up into the

ﬂue pipe). See Fig. 24.

NOTE: The exhaust probe sensing tip extends into

this same area. CARE MUST BE TAKEN NOT TO

DAMAGE THE ESP DURING CLEANING. Bending

of the ESP will make it difﬁcult to remove if it should

become necessary. See Fig. 23.

Clean the boiler blower plate, sealing overlap. See Fig

24. Make sure there are no ﬂy ash buildups that may

block the easy ﬂow of ﬂue gasses into the combustion

blower inlet hole. ( A ﬂashlight may be necessary. )

Sealing Overlap

Cleaning the Tube Heat Exchangers:

5” Double

The heat exchanger tubes have external handles that

operate the cleaning mechanisms. See picture on page 32.

This cleaning should be done at least once a week,

although it can be done as often as desired. The cleaner

the heat exchangers are, the more efﬁcient the boiler

will be. This cleaning can be done at any time and in

any mode of operation. During high ﬁre periods, the

cleaning rods may stick due to heat related expansion.

Bladed Fan

Fig. 24

Combustion Blower Cleaning

Remove the combustion blower heat shield. There are

two latches that hold the shield in place (See Fig. 22). Flip

the latches up and pull the shield away from the boiler.

It can not be fully removed, it can only be moved down

over the wire until it hangs on the junction box.

CAUTION: Inspect ﬂue pipes, ﬂue pipe joints and

ﬂue pipe seals regularly to ensure that smoke and

ﬂue gases are not entering the home.

Troubleshooting

FEEdEr dOES NOT FEEd

SmOKE IS vISIblE COmINg OuT OF vENT

1. No pellets in hopper.

1. Air-fuel ratio is too rich.

2. Firebox draft may be too low for low draft pres-

sure switch in feeder circuit to operate. Check

for improperly closed doors, loose or missing

gasket on doors or hopper lid, or a faulty pres-

sure switch.

3. Feed motor will not run until the ESP

senses 170 deg. F. Maybe you did not put

enough pellets in the burn pot before lighting the

ﬁre manually.

A. Feed rate too high.

B. Draft too low caused by a gasket leak.

lOw hEAT OuTPuT

1. Feed rate too low

2. Draft too low because of gasket leak.

3. Poor quality or damp pellets

4. Combination of 1 and 2.

4. Something is restricting ﬂow in the hopper or

causing the slide plate to stick.

5. Feed motor has failed.

PArTIAllY burNEd PEllETS

1. Feed rate too high.

helpful hints

Cleaning burn Pot

whenever your boiler is not burning, take

the opportunity to scrape the burn pot to remove

carbon buildup. A vacuum cleaner is handy to

remove the residue. be sure the boiler is cold if

you use a vacuum.

2. Draft too low. (Check burn pot clean-out slide

and door gasket).

3. Burn pot or heat exchanger tubes may need

to be cleaned.

4. Combination of all the above.

5. #6 status blink: A 6 blink control board sta-

tus indication is caused by poor or incomplete

combustion. The Automatic Ignition circuit board

has the ability to track the combustion through

feed settings and ESP temperatures. when the

control board has calculated poor or incomplete

combustion, it will shut down the unit as a safety

feature. (Poor or incomplete combustion is a

contributer of creosote which may cause a chim-

ney ﬁre)

A 6 blink status may be caused by several

things:

1. Blocked or partially blocked ﬂue.

2. Blocked or partially blocked inlet air.

a. Backdraft damper on the inlet pipe may be

stuck closed.

Carbon buildup can be scraped loose with

the ﬁre burning using the special tool provided

with your stove. Scrape the ﬂoor and sides of the

burn pot. The carbon will be pushed out by the

incoming fuel. Always wear gloves to do this.

removing Ashes

Ashes can be removed while in operation,

but extra care must be taken and always wear

gloves.

Maximum Feed Adjuster settings are not

needed in most cases. Operating in the normal

range (#4) is recommended when maximum heat

output is not required. The ESP prevents the

stove from being over-ﬁred.

Keep the boiler free of dust and dirt.

b. If outside air is installed, the inlet cover may

be blocked.

3. The air chamber under the burnpot may be

ﬁlled with ﬁnes and small bits of ash.

4. The holes in the burnpot may be getting ﬁlled

with ash or carbon buildup.

Fuel

Pellet fuels are put into 3 categories in terms of

ash content. Premium at 1% or less, Standard at

3% or less and all others at 3% or more.

This unit is capable of burning all 3 categories

of pellets due to a patented feeder and burn pot

system.

It should be noted, however, that higher ash

content will require more frequent ash removal,

scraping of the burn pot, and may provide less

BTU’s per pound. Normally, standard and high ash

pellets cost less than premium pellets and can be

cost effective when burned in this boiler.

The moisture content must not exceed 8%.

Higher moisture will rob BTU’s and may not burn

properly.

5. Combustion blower fan blades may need

cleaned.

6. There is no fuel in the hopper.

SmOKE SmEll

Seal the vent pipe joints and connection to stove

with silicone.

FIrE hAS gONE OuT

1. No pellets in hopper.

2. Draft setting is too low.

3. Something is restricting fuel ﬂow.

4. Feed motor or combustion blower has failed.

5. Power failure or blown fuse.

Atmospheric Conversion

Atmospheric Conversion: Item # 1-00-232200, provides automatic ﬁll, and converts the heating

system plumbing from pressurized to a zero pressure system. Allows for installation into more

places where codes and standards restrict pressurized systems. Note that when using the atmo-

spheric conversion, air bleeders and check valves may actually allow air into the lines. Another

reason it is important to have a licensed Plumber involved in each phase of your installation.

when using the atmospheric conversion, the circuit board dipswitch #6 must

be in the “ON” position. This will lower the overheat temperature parameters

to prevent boiling of the water. Since altitude affects the boiling point, it is also

recommended to set #6 to “ON” at elevations above 3000 ft.
