Toyotomi LASER531 Kerosene Vented Heater 22000 Btu/h

Product Description

The TOYOTOMI LASER531 is a kerosene-fired, direct-vent wall heater rated at 22,000 BTU/h, designed for residential space heating without the need for a chimney or dedicated ductwork. The unit connects to the outdoors through a single 2.75-inch wall penetration for the flue pipe, making it a practical choice for rooms where conventional vented heating is difficult to run. Built-in Wi-Fi allows remote control and scheduling from a compatible device. The cabinet surface stays cool to the touch on the top and side panels, reducing burn risk in occupied spaces. A licensed HVAC technician or qualified installer handles typical setup and commissioning.

The LASER531 is suited for residential installations in living rooms, dens, additions, or other spaces requiring a standalone, zone-heating solution. The direct-vent design eliminates indoor combustion air draw, keeping the unit self-contained and code-friendly in tightly constructed buildings. The cream-colored cabinet blends with standard residential interiors. Its compact footprint allows installation in areas where larger heating appliances would not fit. This unit is intended for use with kerosene fuel and is not compatible with natural gas or propane.

Installation Notes

Installation should be performed by a qualified HVAC technician or installer familiar with direct-vent appliance requirements and local building codes. Before any service or flue work, shut off the fuel supply and allow the unit to cool completely. The wall penetration for the flue pipe must be sized and sealed per the manufacturer instructions and applicable mechanical codes. Verify local fire and fuel-burning appliance codes before installation, particularly in multi-family or commercial settings.
