OPERATIONAL OVERVIEW
As previously stated, the TARM EXCEL boiler may be used either with or without a heat storage
system. This boiler may also be fired on wood only, be operated with automatic switchover to the
oil (or gas) burner if it runs out of wood and starts to lose temperature, or it may be fired on oil (or
gas) only. This operational flexibility results in numerous possible operating scenarios which will
call for different aquastat control settings to be used. The aquastat control settings recommended,
on pages 35 and 50, are given as a starting point. The boiler operator may find, with experience
that these settings can be modified somewhat to optimize boiler and heating system performance.
Please contact us at TARM USA, INC. if you have questions or concerns after you have your boiler
in operation.
BEFORE YOU BEGIN
SAFETY NOTICE: READ THIS ENTIRE MANUAL BEFORE YOU INSTALL AND
OPERATE YOUR NEW BOILER. FAILURE TO FOLLOW THE
INSTRUCTIONS MAY RESULT IN PROPERTY DAMAGE OR
BODILY INJURY.
To operate your boiler in disregard of the information provided in this section can cause
permanent damage to your boiler and void your warranty.
WARNING: NEVER USE GASOLINE, KEROSENE OR OTHER FLAMMABLE LIQUIDS
TO START OR MAINTAIN SOLID-FUEL FIRES IN YOUR BOILER --
SERIOUS BURNS OR PROPERTY DAMAGE MAY RESULT!
NOTE: Do not be alarmed if you smell an unusual odor the first few times you fire the
boiler. This smell is due to burning of oil residues in the paint on the boiler and the
smoke pipe. Ventilate the boiler room well for the first few hours during the first fire.
LOW TEMPERATURE FLUE GAS SENSOR AND TIME DELAY MODULE
The low temperature flue gas sensor and the time delay module work together to shut off the wood
combustion draft fan after a load of wood fuel has been consumed so that the fan won’t continue to
run unnecessarily. If the draft fan continued to run after the boiler ran out of wood fuel it would
waste electric energy and cool the boiler. The flue gas temperature sensor should be set at
approximately
120
°
C initially. This setting may need to be adjusted somewhat, higher or lower, to
optimize performance and to leave enough charcoal to easily start your next fire. The time delay
module should be set at 15 minutes. This setting also may need to be adjusted somewhat to
optimize performance.
When the boiler is set in the “AUTO BACK-UP” mode, the oil or gas burner will automatically be
switched on if the flue gas temperature sensor and time delay module shut off the wood draft fan.
