Hot Dawg 125,000 BTU Natural Gas Garage Ceiling Heater

A:  The fan used in this series of Modine units is not intended to distribute heat any significant distance. The fan is designed into the product to make sure there is adequate flow of air across the heat exchanger so that it does not build up and cause the unit to overheat. The distribution of heat is accomplished by the same principal used by a wood stove. Heat chases cold. The units with the external squirrel cage blower are designed to move air much greater distances. However 44’ is a tall order without duct work. If you look at the Use and Care Manual for this model you will find informational graphs on the blower performance. The next size up would be the PDP series. That series has many external blower options. Each of those models can be special ordered with different motor ratings and pulley sizes to achieve the desired air volume and velocity. For example these are the styles used in smaller airplane hangars or when the unit heater is going to feed duct work.

A:  This is a residential version of a commercial unit heater. As such it was not designed to be particularly quiet. But as describing something as quiet or loud is subjective let me offer you some precise ratings. This unit has been rated as producing 58 decibels of sound when measured from 10 feet away. And the immitted sound has been measured at 57 decibels at a distance of 15 feet. If you look at a decibel equivalent chart you will find that most describe the sound level of 50-60 decibels as similar to the sound of normal spoken conversation, heavy rainfall or the sound of a refrigerator running.

A:  If you look under the header "Info and Guides" on the Home Depot product listing page you will find a PDF labeled instructions. Discussion of high altitude adjustment an kits begins on page 13. It indicates that at 6000 feet above sea level you would need kit 68408. That kit can be ordered no charge with your unit. Modine does not factory install high altitude kits on these units they must be installed in the field. The vast majority of units sold are the standard models. However, if you want to custom configure a unit as a factory special order, you could do that. Options would include two stage gas valve, stainless steel heat exchanger, sealed combustion, and voltages other than 120. If you want to give me a call I will gladly email you the Modine factory list price sheet which will list these options. Please note The Home Depot currently does not accept special orders on line so any such order would need to be place through a store. Chris 978 651 3301

A:  Mine was propane, so the first thing I had to do was order a high altitude (5600') conversion kit because they sent me a natural gas unit. I then had to purchase a 125V 22 amp in line thermostat. I ordered a kit for hanging the furnace so I could swivel the whole furnace in the direction I wanted. When it was all installed I could not get it to work and finally found I had to make a jumper for the heater control board from the W to R terminals. This allowed the heater to ignite and cycle thru all the modes.
