HOLD
FLAME HOLD FLAME mode purpose is to avoid burner start-up procedures when BURNING cycle is
much longer than WAITING status. In HOLD FLAME mode, minimum fuel and air amount is
delivered into burning chamber. HOLD FLAME mode can be switched from burner main
menu to ON, OFF or AUTO. When HOLD FLAME is selected as AUTO then burner will turn the
mode on or off depending of WAITING time:

If time between two sequential WAITING states has been shorter than set in PAR11, then
HOLD FLAME mode is switched on.

If HOLD FLAME time has been longer than set in PAR12 (30-90 min), HOLD FLAME mode
is swiched off.
AUTO status lasts time set in PAR12 and ends with END BURN cycle. In HOLD FLAME
cycle, burner is fed pellets every 127 seconds and air is blowed as set in PAR10.
END BURN Boiler has reached estimated temperature and boiler thermostat has switched burner off.
No fuel is added in this state. External auger is stopped, feeder and fan work until all fuel is
burnt.
END BLOW Photocell doesn`t recognize flame in the burning chamber, fan keeps on working with speed
set in PAR9 up to all pellet coal is burnt. That state lasts time set in PAR27, after flame
dissapearence.
7.5 Output power levels
Burner has 6 pre-set output power levels. For every level, the program calculates correct fuel amount
what depends on fuel’s calorific value and burner’s internal feeder productivity. The feeder productivity
for normal, light and heavy pellets can be changed from main menu. Calculated amount of fuel is divided
into periodic feeding cycles. In every cycle internal feeder makes half rotation. If the calculated cycle
comes too short, then the cycle length is doubled and fuel is fed with by full rotation of feeder. For every
power level there is different pre-set fan rotation speed. (PAR1…PAR6).
Burner selects the output level between pre-set min and max powers. If burning time has lasted more
than set in PAR15, in next burning cycle burner will increase one power level up. If burning time has been
less than set in PAR16, in next burning cycle burner decreases one power level down.
