Firing The Furnace; Filling The Firebox - Central Boiler CL 4030 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).
1. The first time you fire the outdoor furnace, place dry
kindling wood near the front of the firebox. Use a
small amount of paper to light fire.
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. After a few days of operation you will begin to learn
how much wood is needed each day. If you only add
the amount needed, it is easier to stir the ashes along
the sides of the firebox and then to pull them 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.
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

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.
WARNING
Keep your face away and stay as far away as
possible from the firebox door area when opening
the door.
1. Unlatch the door; then stay as far away as possible
as the firebox door is opened as smoke and hot gases
escaping through the firebox door opening could
ignite. From a safe distance, observe the fuel load.
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.
Fig. 42
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.
WARNING
When adding wood to the firebox, be careful not
to get pinched between the wood and the door
frame or any part of the outdoor furnace. Use
extreme care with large pieces of wood that may
be difficult to handle.
