slightly and slide the covers outward as shown in the
illustration. To reinstall, simply slide back into place and
retighten the screws.
Firebrick
Install the rebrick vertically on the angle above the
burnpot.
Flame Guide
Install the cast iron ame guide on top of the burnpot
and make sure it is fully seated against the auger
opening. The bottom of the ame guide is marked 38+.
Draft Test Procedure
Fig. 2
Rear Cover
Panels
Shipping Bolts: These
holes are also used for
Mobile Home Installation
Before attaching any vent pipe to the stove, perform
a draft test, for later comparison.
Remove the plug bolt on the underside of the rebox
as shown. Using the hole from the bolt, attach a draft
meter that is capable of reading at least .5 inches of
water column (W.C.). You are going to want the meter
reading negative pressure.
Turn the feed adjuster to "Test". For the rst minute,
everything will run. Record the high draft reading
_______ . After the rst minute, the distribution blower
will go to a low speed. Then, after the second minute,
two minutes after turning to test, the distribution
blower will come back up to high, and the combustion
blower will drop to low. During this time, record the low
draft________. Perform the test again after the venting
is complete. Compare your readings. If there is more
than a .05 difference, you have too much restriction in
the venting. There is no adjustment for the draft other
than improving the venting conguration. Leaving the
stove in "test" will continue to cycle the blowers each
minute. Record your nal draft redings here. _________
High, and ________ Low.

Installation
Installing
Place the stove on a non-combustible oor or a oor
protector providing a minimum .84k value. Floor protection
must extend 6 inches to the front, 6 inches to the sides
and 1 inch to the rear of the stove.
Place the stove away from combustible walls at least
as far as shown in gures 3,4 and 5. Please note the
difference in side wall clearance with and without side
shields.
Note that the clearances shown are minimum for safety
but do not leave much room for access when cleaning
or servicing. Please take this into account when placing
the stove.
Connect the power cord to a 120 V.A.C. 60Hz grounded
receptacle.
After connecting the ue system, perform the second draft
test. However, prior to taking the draft reading be sure all
doors and windows in the home are closed. Record the
draft reading_______. If this reading is more than .05"
lower than the unconnected reading, check for possible
restrictions or the need for outside air (see page 7).

Venting
Requirements for Terminating the Venting
WARNING: Venting terminals must not be recessed
into a wall or siding.
NOTE: Only pellet vent pipe wall pass-throughs
and re 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 yash and /or smoke when placing the
termination.
In addition, the following must be observed:
A. The clearance above grade must be a minimum
of 18".
B. The clearance to a window or door that may be
opened must be a minimum of 48".
(with outside air installed, 18”)
C. A 12" clearance to a permanently closed window
is recommended to prevent condensation on the
window.
D. The vertical clearance to a ventilated soft 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".
E. The clearance to an unventilated soft 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)
above a meter/regulator assembly when measured
from the horizontal center-line of the regulator.
I. The clearance to service regulator vent outlet must
be a minimum of 6 feet.

IMPORTANT NOTICE
Pellet Vent "L" or "PL" Vent Pipe Must be used.

+
A combustion blower is used to extract the combustion
gases from the rebox. This causes a negative pressure
in the rebox and a positive pressure in the venting
system as shown in g. 6. 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 15 feet or less
of vent pipe. The maximum horizontal run should not
exceed 48". If more than 15 feet of pipe is needed, the
diameter should be increased from 3" to 4" because
a larger pipe causes less ow resistance. Be sure
to use approved pellet vent pipe wall and ceiling
pass through ttings to go through combustible
walls and ceilings. Be sure to use a starting collar to
attach the venting system to the stove. The starting
collar must be sealed to the stove with high temp
silicone caulking.
Vent Pipe
Pellet vent pipe (known as type "L" or "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 clearance
to combustibles of only 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 P61 operates with
a positive vent pressure we specify that the joints
also be sealed with high temp silicone.

(ts only 3" pellet pipe)
Outside Air
Outside air is optional except in mobile homes and
where building codes require. The benet of outside air
is mainly noticed in small very tight houses.
To install outside air use 2 3/8" I.D. ex pipe part
number 1-00-08543 (25 ft.). There is a break-away
hole on the rear panel which must be removed before
connecting the ex pipe. The pipe should be run outside
and terminate to the side or below the vent pipe outlet
so the ue outlet is more than 12" from the inlet cover.
The maximum length run of this pipe is 15 feet. If a
longer run is needed the size must be increased to 3".
Inlet cover part number 1-10-08542 should be used to
keep birds, rodents etc. out of the pipe.
HRV
When installing in a house with a Heat Reclaiming
Ventilation System (HRV) be sure the system is
balanced and is not creating a negative pressure in
the house.

Venting
#1 Preferred method
This method provides excellent venting for normal
operation and allows the stove to be installed
closest to the wall. Two inches from the wall is
safe; however, four inches allows better access to
remove the rear panel. The vertical portion of the
vent should be three to ve feet high. This vertical
section will provide natural draft in the event of a
power failure.

3 ft.
to combustibles
#2 Preferred method
This method also provides excellent venting for
normal operation but requires the stove to be
installed farther from the wall. The vertical portion
of the vent should be three to ve feet high and at
least three inches from a combustible wall. This
vertical section will provide natural draft in the event
of a power failure.
