4.4 Adding Wood
4.4.1 Adding Wood When the Draft Fan is OFF
(Boiler at Operating Temperature)
1.
OPEN THE BY-PASS DAMPER.
2.
TURN UP THE OPERATING THERMOSTAT (I)
on the control panel fully clockwise.
This will activate the draft fan, to help prevent the risk of a gas explosion when the door is
opened. Let the fan run for 2-3 minutes to vent the hot gasses before the door is opened.
3. Turn the draft fan off by switching the fan switch
(F)
to ―OFF‖ on the control panel.
4. Without delay, open the load door ¾‖ with your
left
hand.
5. Wait approximately 20 seconds.
6. Open the load door slowly, fully, and
cautiously!
7. Load the firebox if the previous load of wood has burned down to coals, placing the wood uni-
formly front to back and tight together, not crosswise. If the wood has not burned to low coals,
do not load more wood.
8. Close the loading door.
9. Turn the draft fan back on by switching the fan switch
(F)
to ―ON‖ on the control panel.
10. Close and lock the by-pass damper by pushing in and down firmly so that the spring will keep
it closed.
4.4.2 Adding Wood When the Draft Fan is OFF
(Boiler Temperature
below
140ºF (60ºC))
1.
OPEN THE BY-PASS DAMPER.
2. Push the reset switch
(N)
on the control panel to activate the fan. Let the fan run for 2-3 min-
utes to vent any hot gases.

(F)
to ―OFF‖ on the control panel.
4. Without delay, slowly and cautiously open the loading door ¾‖ with your
left
hand and wait
approximately 20 seconds.
5. If there is sufficient live coals left in the firebox to re-ignite the next load of wood, there will
not be the need to use paper to restart the fire. Place several pieces of dry kindling in the cen-
ter of the firebox over the slot in the refractory and rake the live coals from the sides of the
firebox to the center on top of the kindling.
6. Add enough firewood to carry the estimated heat load for the next 8 hours, as per the ―Daily
Firing‖ on

, which are very important.

(F).
Close and lock the by-pass
damper by pushing in and down firmly so that the spring will keep it closed.
10. HOWEVER, if you find very few live coals left in firebox after opening the load door in step
#3 above, follow steps 3-#10 in
Section 4.3
to restart the fire.
