7. Locate and install outside air temperature sensor. Loca­tion of this sensor should be on the north side of the home or
building and out of direct sunlight. Use the cable supplied
with the boiler to attach the sensor to the terminals located
on the hopper. (Place at the back side just above and to the
right of the main power connection box) The wires can be
connected to the sensor with the connectors supplied. Wire
nut or butt splice connectors could also be used. The con-

nections at the boiler can be done with the two 1/4” female

push on connectors supplied.

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

Design:

The rst 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
certied dealer or a qualied HVAC or plumbing contrac­tor. This will ensure that the boiler is installed and piped to
accommodate your needs and expectations.

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.

Avoiding Smoke and Odors - Negative Pressure,
Shut-down and Electrical Power Failure.

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 in­stallation. Heat rises in a house, and leaks out at upper
levels. This air must be replaced with air from outside

the dwelling, which normally ows into lower levels.
Vents and chimneys into basements and lower levels

can become the conduit for return air and reverse un­der 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 oor

locations. Per national building codes, consideration
must be given to combustion air supply to all combus­tion appliances. Failure to supply adequate combustion
air for all appliance demands may lead to back-draft­ing of those and other appliances within the home.

To reduce the probability of reverse drafting dur­ing shut-down conditions, Hearth & Home Tech­nologies strongly recommends:

• Installing the pellet vent with a minimum vertical
run of 5 feet. Preferably terminating above the roof
line.

• Installing the outside air intake at least four feet
below the vent termination.
To prevent soot damage to exterior walls, and to pre­vent re-entry of soot or ash into the house:

• Maintain specied clearances to windows, doors

and air inlets, including air conditioners.

• Vents should not be placed below ventilated softs.

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 dis­tance may be required if visual accumulation occurs.

Venting

Use 4” pellet vent pipe only.

A combustion blower is used to extract the combustion

gases from the rebox. This creates a negative pressure in
the rebox 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 ow 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.

Be sure to use wall and ceiling pass through ttings

(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 ue collar with

high temp silicone caulking or aluminum tape, and

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

4” Type “L” or
“PL” Vent pipe

This is the minimum venting conguration.

Fig. 4

Vent Pipe

4” pellet vent pipe (also known as “PL” vent) is con­structed 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.

NOTE:Use only 4” diameter approved PELLET
venting system. Be sure to inspect and clean exhaust
venting system frequently.

The minimum vent conguration is a 90o or Tee on
a starter collar and a 24” length horizontal through an
exterior wall. A cap on the end should direct the ue

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 conguration

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
tting in any conguration.

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.

( See the venting graph on page 10.)

Each Vertical ---- 90 deg. or T subtract 2.5 feet
Each Vertical ---- 45 deg. subtract 1.5 feet
Each Horizontal - 90 deg. or T subtract 5.0 feet
Each Horizontal - 45 deg. subtract 2.5 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.

11

Venting Installation

Chimneys taller than 20’ above the connection will

require a draft test to determine if the draft is too high.
Note: The high burn draft should not exceed .85 IWC.
Some form of a restrictor plate may be required at the

top of high chimneys to reduce the draft. See page 21

for the Draft Test procedure.

This boiler may be used and installed into an existing

masonry or Class A metal chimney.

Certain Canadian and Local Codes may require that
the chimney be fully relined.

The venting Can Not be installed in a chimney serv-

ing another appliance.

The chimney should be cleaned and or inspected before

installation of the venting.

NOTE: Use only 4” diameter approved pellet
venting system. Be sure to inspect and clean
exhaust venting system frequently.

INSTALLATION IS TO BE PERFORMED BY
A QUALIFIED INSTALLER.

DO NOT INSTALL A FLUE DAMPER IN THE
EXHAUST VENTING SYSTEM OF THIS UNIT.

DO NOT CONNECT THIS UNIT TO A
CHIMNEY FLUE SERVING ANOTHER
APPLIANCE.

INSTALL VENT WALL PASS-THROUGHS AT
CLEARANCES SPECIFIED BY THE VENT
MANUFACTURER

NOTE: All installation clearances and restrictions
must be adhered to.

NOTE: Read and follow all of the vent pipe
manufacturers’ instructions on the proper
installation and support of the vent pipe. Adhere
to all clearances.

WARNING

KEEP COMBUSTIBLE MATERIALS SUCH
AS GRASS, LEAVES, ETC. AT LEAST 3 FEET
AWAY FROM THE POINT DIRECTLY UNDER
THE VENT TERMINATION. (BETWEEN THE
VENT AND THE GROUND)

CAUTION

KEEP COMBUSTIBLES AWAY

FROM FLUE OUTLET.

Other examples of possible installations of the venting.

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 ue
of a slow-burning re. As a result, creosote residue accumulates on the ue lining. When ignited, this creosote makes an
extremely hot re. 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 re.

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 signicant layer of creosote has
accumulated (3mm or more) it should be removed to reduce the risk of a chimney re.

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

Fig. 6

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, block­ing the intake air supply.

The Outside Air knockout is located on the face of
the Feeder Cover. It is pre-cut except for several small

tabs. There is also a ller plate screwed to the inside

to cover the top of the hole after the Outside Air Pipe
has been installed. This will allow for removal of the
Feeder Cover without disconnecting the Outside Air
Pipe. See Fig. 7.

Only metal Intake Flex should be used for the
Outside Air Supply connection.

The Outside Air Intake Pipe is inside the Feeder

Cover and to the right of the feeder motor. The 2 3/4”
steel ex pipe is made to slide over the outside of the

Air Intake Pipe. See Fig. 8. It should be held into place
with some silicone, foil tape, or a hose clamp. (not
