HOW TO OPERATE THE HEATER
MODES TO DELIVER COMFORT AND ECONOMY
Your appliance has several MODE settings to choose from. The factory default mode is GAS. If the
mode is not adjusted this will be the default setting the next time the appliance is used.
As a room is warmed, the walls and ceilings are also warmed, making one feel a little warmer than
when the ceilings and walls were cold, even though the room temperature is the same. The economy
mode prevents discomfort from overheating and saves energy.
GAS MODE
Gas combustion in this mode is continuous and will adjust automatically to maintain the set
temperature. This is the factory default mode for the appliance.
GAS / ECON MODE (ECONOMY MODE)
In this mode, once the set temperature has been maintained for a period of 30 minutes, the comfort
control system will progressively lower the set temperature by 2°C over a period of 60 minutes. When
GAS / ECON mode is selected, gas combustion is continuous and will adjust automatically to maintain
the set temperature minus 2°C.
