oPERAtIoN of yoUR NEW JACK LINE
Wood BURNING fURNACE

Check that your main blower and draft blower are in proper 
working order before lighting a fire.

Turn thermostat upstairs to high temperature so draft blower 
turns on, then turn thermostat back to proper setting, turning 
draft blower off.

Crumple a piece of paper, place inside, light paper, making 
sure you have a good draft (.03 water column).

Now proceed with lighting a fire.

1.  Open manual draft spinner 3-4 turns.
2.  Make  sure  your  smoke  pipe  damper  is  open.  Place 

several pieces of crumpled paper in the center of your 
firebox. In a criss-cross pattern, place a couple hand-
fuls of dry kindling wood 3/4” thickness, then several 
small dry pieces of firewood.

CAUtIoN

Never use chemicals or fluids such as  gasoline, charcoal 
lighter fluid, drain oil or kerosene to light a fire in your Jack 
furnace.

3.  Ignite  the  paper  and  close  the  door.  Do  not  attempt 

to open door immediately after igniting the fire. There 
could be a flame flash out.

4. It will take a few minutes for the fire to establish itself. 

Once you have some good red hot burning embers, 
add larger pieces of wood. All chimneys and hook-ups 
act differently. After a while you will find out how your 
unit works best for you.

5.  After  a  time  you  can  adjust  draft  according  to  your 

needs. On air tight units, the burning time is controlled 
very much by the draft control on the furnace, contrary 
to the old type stove where the smoke pipe damper 
controlled the burning time. Your Jack Line furnace is 
capable of putting out many BTU’s, so don’t fully load 
your  furnace  or  open  all  drafts  fully  until  you  have 
become  familiar  with  the  operation  of  the  furnace. 
Keep in mind, a full load will not always give you the 
best results for your needs.

NotE

With new steel, there is a small amount of oil or dirt on the 
metal — you may smell an odor. This is normal during the 
first operation.

CAUtIoN

Use  caution  when  opening  loading  door. Avoid  opening 
loading door rapidly. This could cause flame to flash out 
door. This occurs when there is unburned fuel and a large 
amount of gases on top of the fire box. When the door is 
opened, oxygen is combined with the gases and ignites.

HELPfUL HINtS

Set the draft to proper setting. The chimney, hook-ups, and 
kinds of wood will be a factor.

Your Jack is capable of holding very large logs. 

do Not try 

to add a log that is larger than what you can easily place in 
the furnace. You will get best efficiency when you add only 
the amount of wood needed for a 4 to 6 hour burn.

In the spring and in the fall when the weather is mild, burning 
large  loads  of  wood  for  long  periods  may  cause  creosote. 
Stack temperature should be 300º for good burning. Again, 
depending on the weather, you may not need a full load of 
wood  for  a  good  overnight  burn. You  will  get  the  best  effi-
ciency when you add only small amounts of wood.

You can use wood of various shapes, diameters and lengths, 
but not to exceed your unit’s specifications.

Always  try  to  place  the  logs  so  air  has  free  flow  between 
them, increasing combustion.

ASH REMoVAL

When burning wood, every morning when there is just a bed 
of hot embers, run your poker over top of grates making sure 
grate slots are clear of burnt fuel.

Once every week or two, depending on how much fuel you 
burn, ashes should be removed.

CAUtIoN

Never let ashes build up to grate level. This will reduce 
the life of your grate.

To remove ashes, simply pull out your ash pan. But remem-
ber, the ash pan can get very hot. Dump ashes in a metal 
container  with  a  lid  that  is  placed  on  a  non-combustible 
surface.

CAUtIoN

Never  use  anything  but  a  metal  container  to  put  your 
ashes in. Every year fires are caused by emptying ashes 
into cardboard boxes or paper bags.
