SERVICE INFORMATION
7-1 Water Temperature
The tank water temperature is maintained by the Process Control Module. The normal
operating temperature of 170° F to 172° F is preset at the factory and should not be
adjusted.
7-2 Fuel Usage
Hardy Manufacturing recommends the use of wood pellets. Any fuels other than
those specified will result in poor and erratic heater performance. This heater is
designed to use a minimum amount of fuel but as with any heater of this type fuel
usage is based upon the required load and temperature requirements. Refer to the
troubleshooting section located in the appendix for problems associated with excessive
fuel usage or poor heater performance.
7-3 Moisture in the Firebox
During startup of a new heater or the first time you operate an existing heater each
year, you will probably notice moisture in the firebox. This is normal and should not
cause alarm. If after a few days of operation a high moisture content is still evident the
heater should be shut down and checked for leaks.
7-4 Improper Burning
Improper burning during the normal operation of the heater is normally caused by lack
of combustion air or fuel in the firebox chamber. First, verify the Feed Auger Assembly
is engaged and operating. Open the Firebox Door and carefully view the fuel inlet
located in the rear right hand section of the Firebox Burn Chamber. Verify that raw
fuel is present. If no fuel is present, there is possibly a blockage in the Auger system
that needs to be corrected. Second, if the Auger System is operating properly the
heater should be shutdown and cleaned according to section VIII Heater Maintenance.
Remove the Stir Shaft Assembly according to section 9-4 Maintenance Instructions,
and check for clogged orifices in the Stir Shaft Fingers.
7-5 Ash Removal
Ashes must be removed from inside the heater on a routine basis. Excessive ash
buildup inside the Firebox and recovery chambers will reduce heating efficiency and
can lead to premature breakdown of some of the internal components. Refer to
section 9-4 Maintenance Instructions for ash removal.
