The GN5/GP5 (natural gas/propane) is the newest model produced for the Val6 series. It incorporates a gas burner into our infrared heater technology as it utilizes a premixed combustion burner that creates a blue flame due to premixing the fuel gas and air in advance. This means virtually silent operation and clean combustion.

CLEAN COMBUSTION - The efficiency of our premixed gas combustion system means the GAS VAL6 produces less than 1 ppm of carbon monoxide - 10-20 times less than typical torpedo-style heaters.

QUIET OPERATION - The premixed gas combustion allows VAL6 GN5/GP5II to minimize operation noise, coming in at about 60dB as compared with a typical forced air heater, at 75dB, or more.

ADJUSTABLE ANGLE - Ther vertical angle of the radiation disk is adjustable up to 90 degrees.
