1. **Ductless Horizontal Vent Kits**: These kits are easy to install and do not require any ductwork. They are ideal for garages with limited space or where running ducts is not feasible. The heater blows hot air horizontally through a vent attached to the heater, heating the garage efficiently.

2. **Duct Horizontal Vent Kits**: These kits require ductwork to distribute heat throughout the garage. They are suitable for larger garages or those with multiple areas to heat. The heater pushes hot air into the ducts, which then travel through the garage, exiting through vents in the desired locations.
