HOW THE FLAMES SHOULD LOOK FOR PERFECT COMBUSTION
LOWEST SETTING
Small blue flames at the crown.
Blue spears in the pot.
Base of catalyser is red.
Draft has to be between 0.8 and 1.2 mm water column.
MEDIUM-LOW SETTING
Small blue flames developing from the crown.
Top of catalyst is dark red.
Blue spears in the pot.
Base of catalyser is "living red".
MEDIUM SETTING
Flames arrive up to about ¾ of the firebox.
The top of the flames is "white/yellow".
The base of the flames is blue.
Blue spears only on the top of the burner.
Base of catalyst is red.
MAXIMUM SETTING
A large, full-firebox flame reaching above the glass door
frame, though not touching the top plate of the stove.
A narrow flame, mainly white/yellow.
The base of the flames is blue.
The base of the catalyser is red.
Draft: between 1.8 and 2.2 mm water column.
TIP: If your chimney is slow in establishing suction, excess oil may build up in the base of the
burner pot. This causes a flame larger than normally expected at the low setting. Turn the oil
control knob to the OFF position (“O”), allow the flame to reduce in height, then switch the knob
back to low setting.
