Asked by NorthlandPhil April 20, 2021

Answers

I think you are asking if the use of B-Vent changes the venting requirements outlined in the installation manual. The answer is no. Assuming B-Vent is what is required by code and the inspector in your area, the venting prodigal certified by ETL would not change.

Is this a single stage or a two stage unit?

Asked by NorthlandPhil April 4, 2021

Answer

This version has a single stage gas valve and aluminized heat exchanger as apposed to stainless steel. If you want either of those options or the others that Modine offers, they can be special ordered through a Home Depot store. Chris 978 651 3301

Can the Modine Hot Dawg 45,000 BTU Natural Gas Garage Ceiling Heater be installed in the crawl sp...

Asked by Fagen February 23, 2021
2
Answers

The Modine Hot Dawg is often referred to as a garage heater because that is where it is most often installed. However, it is often the heater of choice in other applications; such as green houses and work shops. As to whether it is best choice for your application I can not tell you because I am not on site and can not speak with authority as to the codes in your state. To get a definitive answer you would need to speak to either a qualified licensed heating professional, in your area or the code enforcement official your town. But let me say this, I think the idea of heating a crawl space to prevent it from acting as a heat sink to the area above makes perfect sense. Heat chases cold. The greater the differential in temperatures the faster this occurs. So by raising the temperature of what is typically a unheated area, can often make the adjoining living space a lot more comfortable. Typically you do not need to get them to the same temperature. Just lowering the temperature difference is enough to greatly increase the comfort in the living space. Often when customers complain about cold bed rooms above a garage, I tell them to heat the garage. They usually ask, Why would i do that? I then tell them you already are, that is why the bedrooms are cold, you are just not doing a good job of it, which is why the bedrooms are cold. If you add the capacity to heat it you most likely won't use significantly more energy, you will just be more comfortable and have greater control.

No, you have to purchase one separately. That's nice because then you can decide for yourself if you want one that's programmable or not.

That might be a stretch for a 45k. My 45k is in a 576 sq ft garage, one common wall with house, 8 ft ceiling, some insulation. I think it's just right (Northern Ohio on Lake Erie).

Does the heater come with a roof installation kit?

Asked by Jeff October 5, 2020
1
Answer

I am unsure what a "roof installation kit" is. So I would say no it doesn't. What comes with this item is just the furnace. All other items such as venting material, thermostat, hangers, pipe, ect. are sold separately. What comes with this unit is outlined in the installation manual. A PDF of which can be found under the header, "info and guides" on the Home Depot product listing page.

I have a 36ft by 40ft garage with 16ft ceiling with a loft what size heater should I buy

Asked by Larry September 30, 2020
1
Answer

Square footage of floor space along with the structure's volume are only two of the factors that go into sizing a furnace. As an example I am sure you could envision its going to be a vastly different heat load if the structure in question is in Alaska than if it were in Florida. The proper way to size a furnace is to do a heat loss calculation. There are plenty of free programs on line for this. I personally use the Slant Fin heat loss calculator that can be down loaded for free at either the Droid or Apple ap store. Once you put the factors into the program. Again dimensions, location, building material, lineal feet of outside wall, the program will calculate the heat loss on the coldest hour of the coldest day of the statistical year. The logic being, if you can replace what the structure will lose on the coldest hour of the coldest day of the year, you can keep it warm. Thus I typically then select an appliance with that figure as an output. The only time I vary from this is with garages. For example the heat loss calculation on my garage came to 45000 BTU's but I installed a 100,000 BTU unit. Why? Because I don't keep my garage heated. I keep it unheated and only turn the heat on when I am doing a project. If I sized the unit to my heat loss, I would not have the extra capacity to raise the temperature quickly on a cold winter day. Sizing it to my heat loss would make sense if I was keeping the structure at a constant temperature but I am not. Instead I want to be a able to bring in a snow covered vehicle and heat it up in a reasonable period of time. If you have further questions you can reach me at 978 651 3301 Chris

Can I use 4” venting

Asked by Jess September 22, 2020
1
Answer

If you look under the header "Info and Guides" on the Home Depot product listing page you will find a PDF of the installation instructions. The venting requirements begin on page 6 and run to page 11. The instructions outline the methodology that has been tested and certified by ETL the third party testing agency that Modine uses. No other venting methods are acceptable or approved. Nor are any modifications acceptable. As todays venting requirements tend to vary appliance to appliance, it is my experience that the inspector will typically ask for the instructions and will inspect the installation based on the what is outlined in the certified installation instructions. As the use of 4" is not covered in the instructions it can not be used.

Super Hot Dawg
I purchased this heater for my garage to keep the dog warm on the cold Wisconsin winter nights. This system is simply amazing. I heat my two car garage up to a comfortable temperature within 10-15 minutes. The system tucks up nicely on the garage ceiling and does not obstruct any views. Well done Modine...well done.

Do not stand behind warranty if homeowner
As a homeowner and someone who has worked for a heating and cooling company in the past installed the unit as per the requirements. I have had this unit for two years bow and have had to replace the blower motor (oem motor) after only 4 months of use. 1.5 years later I turned my unit on for the first time this season and the motor made a huge noise. I found the motor back blown out and the fan blades hitting the cage. I called modine and they will not cover anything UNLESS one of their authorized contractors install the unit. So just know if you plan on installing the unit yourself, which I know some people are not comfortable or capable of doing so correctly, don't expect modine to be willing to help you if there are issues. Jus wanted to share for those who are capable of doing a perfect install without having to pay over $500 to get it installed. Good luck

Amazing Heater!!
Had this heater installed in my 3 stall garage, about 800sq feet with 10ft ceilings. My garage walls have r-15 insulation and ceiling has r-38. Keeps my garage plenty warm, keep it at 50 degrees in winter to melt snow off car (Michigan). Can heat from 50 to 65 degrees in about 30-40mins. Fairly quiet for a heater. Have it vented out roof. Overall, very happy with this heater.

Quality heater. Installed March 2020 in uninsulated attached 2 car garage in Chicago area. Ran it a few times when it was in the thirties outside and it got the garage up to around 55 and comfortable. Using HONEYWELL CT50K1028 low temp thermostat and 3” b-vent pipe thru roof. Plan on fully insulating garage now and keeping it around 40 next winter. Spend a little more for this Made in the USA!!! unit.

Excellent product. Heats my 2 car garage with 10’ ceilings with ease. I insulated the ceiling, walls and garage door and garage is always warm even in freezing weather. Doesn’t run a lot and is quiet enough to enjoy a game of cards while easily talking over it when it periodically comes on.
