Convection: The device heats the air around it, which rises to the ceiling. As the warm air gathers at the ceiling and increases in volume, it moves lower toward the floor. Example: open flame heating the air above.

Forced Air: The device has an internal heat source with a fan behind it that blows air through the heat source, warming it and distributing it into the area. Example: blow dryer or heat gun.

Radiant: The device heats a burner face made of ceramic tiles or metal screen, which sends out infrared waves that heat objects in front of them. Example: feeling the warmth of the sun on a cold day.

Bluegrass Living products are certified to ensure high quality and safety. Some are marked "indoor safe," depending on residential or commercial standards.

Residential: Safe to use in your home (if local laws allow). Always follow the manual and ensure proper ventilation. This includes our portable and vent-free heaters.

Commercial: Intended for heavily ventilated indoor areas such as garages, construction sites, or workshops. Standard ventilation: 1 sq. inch per 1,000 BTUs. This includes our Unit, Garage/Shop, and Forced Air Propane heaters.

Check your local codes. For example, Massachusetts and Canada prohibit indoor propane heaters. California allows portable units in garages or tents, but not vent-free heaters in dwellings.

New items come with a 1-year warranty, and refurbished items have a 30-day warranty. For service or parts, contact a licensed professional for help with installation or repairs.

A BTU (British Thermal Unit) is a scientific measurement of heat. A higher BTU rating typically means greater heating capability.

ODS stands for Oxygen Depletion Sensor. It monitors surrounding oxygen levels and shuts off the heater if oxygen drops below safe levels. ODS is required in all ventless units for safety.

Not all heaters require a hose or regulator to function, or multiple options may exist based on hose length or setup. Consult a licensed installer to choose the correct hose, regulator, and fittings for your installation.

W.C. (Water Column) is a measurement used for low-pressure gas. 1 PSI = 27.7 inches W.C. It’s used to measure small pressure differences in gas lines.

All units must be measured in W.C. to avoid damaging the regulator. W.C. is measured with a manometer. Contact your local gas company or HVAC-certified technician for testing.
