Key Features
Air and gas are mixed in the combustion head for stable low-NOx combustion.
Combustion air and burner head settings can be adjusted to tune combustion parameters.
The hinged body opens naturally for easier inspection and maintenance.
A servomotor adjusts minimum and maximum air flow for the firing stages; when firing is suspended, the damper closes to reduce furnace heat loss.
GC variants use a cam-driven servomotor to adjust air and fuel supply together, while GE variants use two servomotors for separate control.
A flange and high-temperature insulation pad are used for boiler connection.
Combustion air intake includes a throttle damper.
Single-phase motor drives the fan.
Flame supervision uses an ionization electrode and ultraviolet photocell detection.
Electrical protection rating is IP40.
