OPERATING YOUR BOILER (continued) PAGE 45
OPERATIONAL PROCEDURES WHEN NO HEAT STORAGE TANK IS CONNECTED
The following operational procedures should be followed, especially when the boiler has excess
capacity, (as it will have during milder weather):
1. Load the boiler with wood at least 3 times a day.
2. Only load the boiler with the amount of wood needed for the demand caused by the
weather and the heat loss of the house to last approximately eight (8) hours. The wood
should be totally burned and reduced to low coals before you reload. The ability to judge
the correct amount of wood for each load can only come from experience. There are
many factors to consider and each installation is somewhat unique.
3. If steps 1 & 2 above are followed, the heating surfaces of the wood firebox will have a
chance to be dried out from the heat of the charcoal, at the end of burning of each load
of wood.
4. If steps 1 & 2 above are followed, you will have no problems with smoke spilling out of
the loading door because only coals will be present when reloading. The next batch of
wood will ignite easily and quickly because of the presence of the coals remaining from
the previous load.
5. If steps 1 & 2 above are followed, the by-pass damper will open easily and won’t be
stuck shut with creosote.
6. Maintain a high boiler temperature of at least 180° F.
7. Clean the boiler frequently as per the instructions elsewhere in this manual (see pages
51 and 52). Routine cleaning will help maintain boiler efficiency. Accumulated ash and
soot act as an insulator and reduce boiler heat exchange efficiency.
8. Due to greatly reduced heat demand, it is complicated to fire with wood in the summer.
Therefore, we do not recommend burning wood in the summertime. Save your
wood fuel for colder weather, or equip your boiler with a heat storage tank system.
Contact TARM USA, INC. for more information on heat storage tank systems.
NOTE: The refractory tunnel must be kept free of ashes and charcoal so that there is
enough room for the gasification flame. Use the ash rake to pull the ashes and
coals out of the tunnel. Leave the coals on the floor of the boiler and they will burn
up when the boiler fires next.
NOTE: Keep in mind that the refractory bricks are hardest when they are new. They get
softer with age. When loading wood and using tools around the refractory areas
keep this in mind. Don’t break the refractory by 1) throwing wood directly onto the
refractory (place the first few pieces into the boiler gently) and/or 2) digging or
prying at the refractory in the areas of the slot or tunnel.
