P68 Pellet Stove

Installing

Place  the stove on a noncombustible floor pro-

tector that extends a minimum of 6 inches to the front,
2  inches  to  the  sides  and  flush  with  the  rear  of  the
hopper. See Fig. 6.The minimum floor protector ma-
terial is  20 gauge  sheet metal.  Other floor  protector
materials are ceramic tile,  stone, brick, etc.

Place the stove away from combustible walls at

least  as  far  as  shown  in  Figures  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 ac-
count  when  placing  the  stove.

Connect the  power cord to  a 120  V.A.C. 60Hz

grounded  receptacle.  (A  surge  protector  is  recom-
mended  to  protect  the  circuit  board.)  If  the  voltage
entering your home is below 116 volts your stove may
not  work  properly.   Also be  sure  that  the  polarity  of
the outlet that  the stove  is plugged  into is correct.

Prior  to installing  the  flue  pipe, connect  a  draft

meter.  (The draft meter must have a minimum range
of  0-.5.)Record  the  first  reading.  Connect  flue  pipe
to  stove  and  be  sure  all  doors  and  windows  in  the
home  are  closed.    Record  the  second  draft  read-
ing_______.  If the second reading is more than .05"
lower  than  the  first  reading,  check  for  possible  re-
strictions  or  the  need  for  outside  air  (see  page  8).
For more information on the draft test procedure, re-
fer to Page 19.

Mobile  Home  Installation

When  installing this  unit in  a  mobile home  sev-

eral  requirements  must  be  followed:

1. The unit must be bolted to the floor. This can

be  done with  1/4"  lag screws  through  the  2 holes  in
the  base  plate.

2.  The  unit  must  also  be  connected  to  outside

air. See page 8.

3. Floor protection and clearances must be fol-

lowed as shown.

4. Unit must be grounded to the metal frame of

the mobile home.

CAUTION:  This appliance  must  be  vented  to  the
outside.

Due  to high  temperatures,  the  stove should  be

placed out of traffic and away from furniture and drap-
eries.

Children and adults should be alerted to the haz-

ards  of  high  surface  temperatures  and  should  stay
away  to avoid burns to skin and/or clothing.

Young  children  should  be  carefully  supervised

when they are in   the same room as the stove.

Clothing  and  other  flammable  materials  should

not be  placed on or near  this unit.

Installation and repair of this Harman stove should

be done by a qualified service person.  We recommend
that  the  stove  be  inspected  before  use  and  at  least
annually  by  a  qualified service  person.  Periodic  clean-
ing  is required  throughout  the  heating  season  and  at
the end of each winter for the stove to work efficiently.
See  cleaning instructions  on  page  21.
