28 x30 garage with 12 foot high walls

I think this will be the right heater for you.

does this unit come with everything to install. pipes and parts to go out the wall of a building?

Asked by Andy August 28, 2019

Answer

No this furnace does not come with everything you would need for installation; it is just the heater. As each installation would require different additional items and each state would have different code requirements it would not be possible to provide everything that you would need. If you down load the installation manual a qualified licensed gas fitter should be able to produce a stock list for you based on their review of the job site. Let me give you a practical example of what I am talking about. Natural gas is under very low pressure. Because of this gas lines need to be sized to make sure you have adequate gas supply at the appliance. If the run is short that pipe diameter may not need to be very large. However if it is long it may need to be up sized. In both situations the final connection size will be the same. But if the supply line prior to that connection is not sized accurately the gas valve will lock up due to the pressure drop created when the gas valve opens. My point is just because the final gas connection is 1/2” does not mean the pipe going to it will be ½”; it must be sized. Another example would be venting. I know some inspectors that are satisfied with type B venting, however there is one town in my area where the inspector wants stainless steel.

Which Modine model do I need per my details below?

Asked by Jeff November 18, 2018

Answer

A chimney is not an exhaust pipe. A chimney is an air column that creates draft. Hot exhaust is routed into the chimney. Because it is warm it rises creating a vacuum in the chimney that pulls more combustion air into the appliance. This process is called natural draft. In order to crate enough draft a chimney needs to be a certain height. As these units are often hung from a ceiling, people would often hang them, run a short piece of venting material through the roof and think they had a chimney. But they did not because the pipe was not tall enough. The short stack did not create enough draft so heat would collect in the unit and it would shut off due to over heating. To solve this Modine put a power vent on all these units. The fan artificially creates draft. They have only come this way for the last ten years. If you look under the header "info and guides" on Home Depots product listing page you will find a pdf of the instructions. An entire section is dedicated to proper venting of this unit. In most areas the code allows for type B-venting however it is always a good idea to check with your local inspector to see what they require. This unit has an AFUE or efficiency of 80%. As a result it is not a condensing appliance,

does it come with a thermostat?

Asked by Jason October 24, 2018
1
Answer

No these units like most furnaces and boilers to not come with thermostats. You would select the 24 volt thermostat of your choice. Keep in mind most thermostats have a range of 65 to 75 Fahrenheit. As these units are often used in garages you may want to select what is often called a low temp thermostat that has a range going down to the 40's

In the Twin Cities metro area. Is a homeowner allowed to make the necessary gas connections themselves?

Asked by Steve May 18, 2018

Answers

Yes in MN if you are the homeowner, occupy the residence and it is a single family home, you can. You are required to pull all required permits in order to do so. Which will involves a leak test and inspection. You would also have to pull an electrical permit through the state or municipality depending on what city you live in.

I have a 24 by 36 by 9 foot garage in Ohio. How many BTU's do I need?

Asked by Jim January 16, 2018

Answer

I am sorry but there is no consistent relationship between room size and how much heating capacity you need to install. As I am sure you can envision the same structure if located in Alaska would need a tremendous amount of capacity compare to if it were located in Florida. The proper way to determine how much capacity should be installed is called a heat loss calculation. A google search will yield a number of free programs on line that will do this. I use the "Slant Fin heat loss calculator" You enter the room dimensions, construction type, geographic location, Etc. and the program will determine how much heat you need to satisfy the load on the statistical coldest hour of the coldest day of the year. Sometimes if I am sizing one of these for a garage, which is not consistently heated, I will use the heat loss as a base line and then go larger. That way I can raise the temp on a cold day.

looking for a heater that the combustion air can be brought in from the outside can this be done ...

Asked by paul September 11, 2017

Answer

The industry term for what you are asking is sealed combustion. This "HS" model is not built for sealed combustion. However Modine does have a version of this called the "HDS" series which is setup for this. We do not sell it on line for a number of reasons, First it is roughly twice the price, second, although it sounds good most applications don't require it and third when someone opts for this they typically want other factory options as well. You can special order this product through a Home Depot store. Unfortunately Home Depot does not currently do special orders on line. If you have questions please feel free to give me a call.

Does this unit require a 110 or 220 outlet? Does it have a thermostat?

Asked by BC April 2, 2017
1
Answer

The units that Home Depot offers on there web site are set up for 120 Volt Single Phase 60 Cycles. However Modine does make these items in other voltages such as 240 and they can be special ordered. This unit as with most furnaces and boilers does not come with a thermostat. Reason being that there are many choices in thermostats so they are purchased separately. This unit has t 24 volt terminals for the thermostat to attache to. This is outlined in the manual which is downloadable from the Home Depot web site. Because these units are frequently installed in garages I typically recommend a low temperature thermostat. Meaning a thermostat the has a greater range such as 40 F to 80 F. Rather than the 60 F to 75 F

do this heaer use a 2 oe 3 wire thermost? Im looking to insall a wifi controlled stat thx

Asked by paul January 8, 2017

Answer

That all depends on how you choose to wire it. I have always used a simple two wire set up for the thermostat, but if you look in the installation instructions you will see that there are ways of using a more complex thermostat wiring schematic. The install manual is available on the Modine HVAC web site.

modine hot dawg 75k btu
Bought this unit 2 years ago for my insulated 24x40 garage. I keep it at 50 degrees when im not working and 62 when i am. Average noise, can still have a normal conversation while its on. Brings the 12 degree temp difference up in about 10-15min. Highly reccomend. Installation isnt too bad either. Hardest part was running gas line from the house to the garage. A little bit more expensive than others but the better quality is well worth it.
