SECTION 8 – OPERATING INSTRUCTIONS

Fuel Quality and Storage

Wood pellets must be stored in a container or building
that prevents rain or other moisture from contact with
the fuel.
WARNING
Do not store fuel within the outdoor furnace
installation clearances or within the spaces
required for fueling, ash removal and other
routine maintenance operations.
• Use only premium quality wood pellets.
• If fans are used in the fuel storage area, they should
be installed so as not to create negative pressures
in the non-habitable building where the outdoor
furnace is located.
CAUTION
Do not burn plastic, garbage, treated wood or
fuels not listed for this outdoor furnace.
NOTE: Chloride or sulfurous gases will generate
if plastic or rubber is burned and will mix with
the moisture from the wood pellets to form
hydrochloric or sulfuric acids in the fi rebox,
creating corrosion.
NOTE: Wood pellets with a high sawdust
content may cause a feed rate interruption. An
interruption in fuel fl ow may result in an empty
burn chamber, or if the blockage frees itself after
the fi re has gone out, a burn chamber full of
unburned fuel.
NOTE: Fuel must be fl owing from the transfer
auger to the burner auger when the burner auger
is turning (see Fig. 49).

Section 8 - Operating Instructions

Fuel Door Closed (fan off)
or
Fuel Door Open (fan on)
NOTE: Fuel must not build up so that it prevents
the fuel door from closing as shown in Fig. 50. This
is an indication the burner auger is obstructed
or has quit turning. If this condition exists,
inspect the burner auger and clean or replace
as necessary. If condition persists contact your
Central Boiler dealer for more information.

FireStar Controller

Refer to the FireStar Operation Manual for instructions
on how to use the FireStar controller.

Operating Precautions

NOTE: If the controller is fl ashing
system senses a low water condition. This
outdoor furnace is equipped with an automatic
shut down system if the water level falls to an
unsafe level. The water level in the outdoor
furnace is safe when the water level indicator rod
is above the vent cap (see Fig. 55).
1. Do not burn garbage, gasoline, rubber, engine
oil, naphtha, plastics, treated wood, cord wood or
combustibles other than the fuel specifi ed.
2. Do not store combustibles within the installation
clearances listed on the Important Precautionary
Information page. Be sure to leave a safe amount
of room for cleaning out ash without causing a fi re
hazard. Keep the area around the outdoor furnace
clear of combustible materials. Combustible
debris may be easily ignited if embers spill out of
the fi rebox.
3. The outdoor furnace water jacket must not be allowed
to pressurize. Inspect the vent cap periodically for
any obstructions or restrictions. The vent cap must
fi t loosely over the vent (Fig. 51). Do not extend or
connect anything to the vent pipe.
