Product Details

Manufacturer: Modine
Modine Part Numbers: HD75AS0121
Item Number: MOE-HD30AS0111
It's no secret that a garage can be one of the coldest areas of your home. That's why Modine designed the Modine Hot Dawg Power Vented Garage Gas Fired Unit Heater. This lightweight, low profile design makes it easy to install, and it installs with as little at 1" from the ceiling. This gives you the flexibility to install your unit where you need it most. Rotating the unit 180 degrees will also create either right, or left, controls and these units boast some of the smallest diameter vent pipe for side-wall or roof venting purposes. These units also come in several different BTU ranges so that you can be sure your garage has the proper amount of heat it needs. So if you're looking for the right way to heat your garage then look no further than Modine for all of your heating needs.

Please Note: Square footage that BTUs will cover will depend on climate zone. The square footage covered is an estimate.

Lawrance from San rafael ca 94901 asked:
Hello, I have this unit and would like to convert it to propane. Do you sell a kit for that? Thank you, Larry 415-307-6333.

A specific conversion kit may be required, and the correct one depends on your unit's BTU rating. Please provide the BTU rating for your unit, and we can help identify the proper part. If your unit is installed at an elevation above 2,000 feet, a propane conversion kit must be used with pressure adjustment methods and potentially a pressure switch kit. For detailed selection and installation information, please refer to your installation manual. Your best source of information will be the manufacturer at Modine Contact Us.
