cheaper), store it properly to aid in the seasoning pro-
cess.  The following steps will assist in the seasoning 
process. 

A.  Stack wood loosely to permit maximum air circu-
lation. 

B.  Do  not  stack  wood  on  the  ground.    Use  a  wood 
rack or stack on scrap lumber.  Storage on the ground 
will cause rotting and insect infiltration. 

C.  Cover  wood  stacks  with  a  tarp  so  that  it  is  not 
excessively exposed to the elements such as snow and 
rain. 

D.  Do  not  stack  wood  against  the  walls  of  your 
home. 

5.5 Building a Fire 

A.  Use  a  log  grate  (sold  separately)  with  your  fire-
place.    This  will  contribute  to  good  air  circulation 
around the wood, and keep the wood out of the ash.  
This grate is shown in Figure 26. 

 

 

B.  Close  windows  located  near  the  fireplace  when 
first lighting a fire to reduce the possibility of smok-
ing.  It can be reopened once a draft has been created 
through the chimney. 

WARNING:  NEVER USE GASOLINE, 

GASOLINE-TYPE LANTERN 
FUEL, KEROSENE, CHARCOAL 
LIGHTER FLUID OR SIMILAR 
LIQUIDS TO START OR 
“FRESHEN UP” A FIRE IN THE 
FIREPLACE. KEEP ALL SUCH 
LIQUIDS WELL AWAY FROM 
THE FIREPLACE WHILE IT IS IN 
USE. 

C. Do not overload the wood grate with wood. Three 
to four logs on the fire at one time are sufficient.  Too 
much wood on the fire at one time can result in “over 

firing,”  and  too  much  heat  in  the  firebox,  causing 
damage to the fireplace. 

D.  When  lighting  a  fire  in  a  cold  chimney,  a 
downdraft may be created, letting a little smoke into 
the room.  To correct this, hold a wadded newspaper 
in the firebox and light it.  This will create an updraft 
and clear the flue of cold air. 

The following steps are recommended when starting a 
fire. 

A.  Remove  any  excess  ash  from  the  fireplace.    Ex-
cessive ash may reduce airflow.  Some owners prefer 
to  leave  a  small  layer  to  insulate  the  cold  refractory 
brick below the grate, helping fire starting. 

B.  Open  and  close the  damper to  ensure  it operates 
properly.    Leave  it  in  the  full  open  position  when 
starting a fire and while the fire is burning.  

C.  Center  the  grate  over  the  bottom  hearth  of  the 
firebox. 

D.  Crumble  several  newspapers  across  the  fire  area 
underneath  the  grate.    Criss-cross  kindling  wood  on 
top of the grate, above the newspaper.  

E.  Lay three logs on the grate; two side by side and 
the  third  in  pyramid  fashion  on  top.    Split  logs  will 
start  faster.    Ensure  there  is  space  between  the  logs 
for  air  circulation.    As  the  air  is  heated,  it  is  drawn 
upwards through the space between the logs, creating 
more combustion. 

F.  Light the paper at both sides of the firebox. 

Caution: The fireplace requires air for operation. 

Ensure there is sufficient air so that other 
fuel burning appliances are not starved of 
combustion, ventilation, and dilution air. 

G.  Set  the  screen  in  front  of  the  firebox  to  prevent 
the escape of sparks and embers. 

H.  Ensure  the  fire  remains  centered  in  the  firebox. 
Don’t let it move to the front part.  Move it back with 
the poker. 

I.  Add wood to the fire as necessary. 

CAUTION: Be extremely careful when adding wood 

to the fire.  Use proper fireplace tools and 
wear gloves.  If adding an un-split log, it is 
possible that it may want to roll out.
