Loading Coal into the HEATMOR™
It is very important to fully educate all those who will be loading the furnace with coal.
Loading a large amount of coal into the HEATMOR™ furnace once a day
is not always
best
. We have found that you have a more efficient fire and produce less smoke when you
add fuel twice a day.
Example:
Half of the days’ demand in the morning and half in the
evening. The number of loadings and the amount of coal needed will vary depending on the
amount of heat being removed.
Here are some suggested points to assist you in loading your furnace.
1) Make sure you have your fuel readily available to fill your furnace. (i.e. a
wheelbarrow full of coal
near
the furnace)
2) Maintain a clear, clean area in front of the furnace.
3) Open the outer front door. This allows you access to the inner firebox door as well as
opens the anti-rollout device. This allows air into the firebox to decrease the
possibility of the exhaust igniting and creating a “flash back” before you open the
main firebox door.
4) Turn on the light switch. The light should turn on and the combustion air blowers
should turn off if they were operating correctly.
5) Standing to the right, next to the exterior door,
with your left hand and your left
arm outstretched,
move the fire box door handle out of the safety latch.
6) Crack the firebox door open about two inches and allow any pressure
left over in the firebox to escape.
7) Open the firebox door as you step backwards towards the exterior door. This allows
you to be out of the way if there is a “flash back” or exhaust exiting the door opening.
8) Set the firebox door handle into the holder provided on the outer door.
9) After all exhaust has been eliminated, give the ashes over the grates a light stirring
with a long rake.
10) Add the necessary fuel to the firebox, being careful not to push ashes into the air
boxes.
11) Close the firebox door and latch securely.
12) Turn off the light switch. This will return power to the blowers and turn off the light.
13) Close and lock the exterior door.
What Should I Burn?
This furnace is designed to burn coal.
Types of coal allowed to be used include: Pennsylvania anthracite, Eastern Canadian
Bituminous and Western Canadian Sub-bituminous.
Learn to load the furnace to most appropriately match the heat demand. Warmer outdoor
temperatures indicate a need for smaller loads, thereby matching demand to supply and
resulting in higher efficiencies. Being aware that your individual “Types of Coal” will aid in
your decisions.
How does a fire burn out?
When the temperature of the HTF has reached its high limit (185 degrees Fahrenheit), the
combustion air blower(s) shut off. At this point, the fire “banks”. When the air combustion
blower(s) turn back on, there may not be enough coals to restart the fire. You will then need
to restart the fire. If this situation occurs , you may want to transfer to your standard system
for better efficiency.
A new unit will require the establishment of “bed of coals” which will aid in re-establishing
proper combustion. This may take a few burn cycles.
