HeatPro Furnace Installation and Operation Manual

9 Maintaining your wood heating system

9.1 Furnace maintenance

Your  new  furnace  will  give  many  years  of  reliable  service  if  you  use  and  maintain  it
correctly. Some of the internal components of the firebox, such as firebricks, baffles and air
tubes,  will  wear  over  time under  intense heat.  You  should  always  replace defective  parts
with  original  parts  (see  Section  11:  Exploded  diagram  and  parts  list).  For  firing  each
load hot to begin a cycle as described above will not cause premature deterioration of the
furnace. However, letting the furnace run with the air control fully open for entire cycles can
cause damage over time. The hotter you run the furnace throughout burn cycles, the more
quickly  its  components  will  deteriorate.  For  that  reason,  never  leave  the  furnace
unattended while a new load is being fired hot.

9.1.1 Ash removal

Ash should be removed from the firebox every two or three days of full-time heating. Do
not let the ash build up in the firebox because it will interfere with proper fire management.

The best time to remove ash is after an overnight fire when the furnace is relatively cool,
but there is still some chimney draft to draw the ash dust into the furnace and prevent it
from coming into the room.

After  ashes  have  been  removed  from  the  furnace  and  placed  in  a  tightly  covered  metal
container, they should be taken outside immediately. The closed container of ashes should
be  placed  on  a  non-combustible  floor  or  on  the  ground  well  away  from  all  combustible
materials pending final disposal. Ashes normally contain some live charcoal that can stay
hot  for  several  days.  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 thoroughly
cooled. Other wastes shall not be placed in this container.

NEVER STORE ASHES INDOORS OR IN A NON-METALIC CONTAINER OR ON A
WOODEN DECK. ALWAYS LEAVE THE CONTAINER ON A NON-COMBUSTIBLE
FLOOR.

9.1.2 Cleaning door glass

Under  normal  conditions,  your  door  glass  should  stay  relatively  clear.  If  your  firewood  is
dry  enough  and  you  follow  the  operating  instructions  in  this  manual,  a  whitish,  dusty
deposit  will  form  on  the  inside of  the  glass  after  a  week  or  so of  use. This  is  normal  and
can be easily removed when the furnace is cool by wiping with a damp cloth or paper towel
and then drying. Never try to clean the glass when the furnace is hot.

In spring and fall the furnace will cycle less  often.  You may see some light brown stains
forming,  especially  at  the  lower  corners  of  the  glass.  This  indicates  that  the  combustion
has  been  incomplete  and  some  of  the  smoke  has  condensed  on  the  glass.  When  the
weather is mild, you may find that letting the fire go out is better than trying to maintain a
continuous fire.  Use  the  technique  described  above  for  building  a  fire  to  take  the  chill  off
the house.
