Firing The Furnace; Filling The Firebox - Central Boiler Pallet Burner Dual Fuel Owner's Manual

FIRING THE FURNACE

NOTE: Before firing the outdoor furnace for
the first time, make sure the proper amount of
Corrosion Inhibitor Plus™ has been added and
the water level is 1" below the full mark on the
sight gauge.
CAUTION
Do not burn plastic, garbage, treated wood or
fuels not listed for this outdoor furnace.
The outdoor furnace is equipped with a digital
temperature controller that closes the outdoor furnace
damper when the water temperature reaches the
controller's setting. The setting can be adjusted so the
outdoor furnace will operate with a water temperature
within a range of 150°F-195°F.
CAUTION
If the water in the outdoor furnace boils, be sure
to check the water level and restore to full. Add
Corrosion Inhibitor Plus™ (p/n 1650) as needed
(see Water Quality and Maintenance).
NOTE: At the completion of the initial start-up
procedures, the gas/oil burner should be cycled
for a test run. During the test run, set all burner
settings according to the instructions and
settings in the burner manual. If converting to a
different type of gas (i.e., LP to NG or NG to LP),
install only the manufacturer's certified kit.
1. To cycle the outdoor furnace with wood for the first
time, turn the control switch to the Wood position;
then place dry kindling wood near the front of the
firebox. Use a small amount of paper to light fire or
operate the dual fuel burner in the Clean Start mode.
2. Add larger pieces of wood to the fire but do not fill
the firebox completely.
3. When the water temperature reaches the controller
setting (185˚F) and the damper closes, let the outdoor
furnace cycle a few times to be sure it is operating
properly; then add more wood.
4. Adjust your fill schedule so that a minimum amount
of unburned wood and coals remain. This will make
it easier to stir the ashes along the sides of the firebox
and to pull coals forward (see Firebox Maintenance).
NOTE: Be sure to clean and inspect the firebox
as outlined in Section 3.
CAUTION
Failure to clean the firebox as indicated will result
in excessive corrosion.
Periodically during the normal operation of the outdoor
furnace, look at the water temperature display. It should
indicate a reading that is within 10°F of the controller
setting.
Section 2 - Operating Instructions
A reading of 212°F or above indicates either a low-water
condition or a malfunctioning temperature controller
or snap disc (unless the door is open or not sealing
properly). If the condition persists and the water level is
correct, call your dealer for service.

FILLING THE FIREBOX

WARNING
Keep your face away and stay as far away as
possible from the firebox door area when opening
the door.
1. Unlatch the doors; then stay as far away as possible
as the firebox doors are opened as smoke and hot
gases escaping through the firebox door opening
could ignite. From a safe distance, observe the fuel
load.
Prior to filling the firebox with wood, always pull the
hot coals forward to the draft area (front and center of
the firebox). With the hot coals pulled to the draft area,
added wood ignites faster because combustion air is
forced through the hot coals and into the newly added
wood. If the coals are pushed to the back, a less efficient
burn will result. If needed to extend the burn time, the
outdoor furnace may be completely filled.
2. If necessary, clean the firebox of excess ashes and/or
crusty deposits.
3. Pull the hot coals forward to the draft area (front and
center) of the firebox.
NOTE: Allow the fire to burn down to 5-10 inches
of coals; then rack the coals forward and level.
WARNING
Use extreme care if adding wood when wood or
coals are already present. Very hot gases may be
coming out of the firebox door opening.
4. Load the firebox with wood being careful not to
be pinched between the wood and any part of the
outdoor furnace.
NOTE: The Pallet Burner is designed to allow
loading with a forklift.
5. If operating in Clean Start or Backup mode, do not
pack wood between the log guard and the end of the
fire tube (see Fig. 37).
NOTE: Use extreme care if adding wood when
a large amount of wood and coals are already
present. Very hot gases will be coming out of the
firebox door.
