Toyotomi Laser 303/304 Direct Vented Heater w/ WIFI

The Toyotomi Laser 303/304 Direct Vent Heating System offers high-efficiency, zone-heating comfort designed to replace older Toyotomi Laser 30, 300, 301, and 302 models. Combining a sleek contemporary footprint with proven direct-vent engineering, the Laser-303/304 delivers the warmth of a central heating system at a fraction of the cost and space. It serves as an economical primary or supplemental heat source for living spaces, basements, hunting cabins, summer homes, workshops, and certified mobile or manufactured housing.

Built for energy efficiency and fuel versatility, the L-303/304 operates on K-1 Kerosene, No. 1 Low Sulfur Fuel Oil, Ultra Low Sulfur Heating Oil, or Ultra Low Sulfur Diesel. Toyotomi’s advanced combustion technology uses up to 50% less fuel to heat the same area compared to conventional systems. Installation is straightforward and requires no chimney, ductwork, plumbing, or complex electrical wiring. The flexible wall flue pipe adjusts to varying wall thicknesses, requiring only a small 2-3/4" opening through an exterior wall for a clean, low-profile outside vent cap.

The Laser 303/304 modulates between four burner modes (including off) to maintain consistent comfort across a range of 5,310 to 15,000 BTUs. It features an automatic ignitor cleaning cycle, power failure recovery, whisper-quiet operation, and a 7-day programmable timer supporting up to 30 unique On/Off intervals. Built-in safety measures include an automatic shut-off system, digital error reporting, and cool-to-the-touch side and top panels.
