## Questions & Answers

**Q: how long would a 100lb propane last if only used 2 days a week on weekends i live in NJ**
A: There's no answer to your question.  What would the temperature be outside?  How many btus does your space take?  1 pound of propane is 21,600 btu's.  Your 100 pound tank will produce 2,160,000 btus.  If your space took 21600 btus per hour, your tank would last 100 hours (4 days).  That's the best answer I can provide.  Thanks Bill    Shurail HVAC

**Q: can this be set up for outside air combustion?**
A: Tom...If you need outside air, you need to buy the HDS45 sealed combustion unit.  It's about $3-400 more.  Typically it's used when the inside air is toxic, such as painting, staining, etc.

**Q: I  have an uneven ceiling, can I sit this unit  on brackets from the wall?  Darrel December 8 2016**
A: There are two ways to support the heather. 1.  Place the heater on top of a shelf 7 or 8 ft or higher. Allow a minimum of 18 inches clearance at the rear of the heater.  2. Mount from the ceiling with 3/8 all thread in each corner of the heater 24" by18 1/2". Use 3/8 nuts and washers to level the heater side to side and front to back

**Q: is there a top or bottom to the 45000,can it be mounted either way?**
A: It can be mounted either way.  You can turn the louvres over as well.  Also there is a spare Hot Dawg sticker in the instruction booklet if you mount it upside down, which I did, to get better access to the controls.  Good luck.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Stop reading reviews, this is the heater you want !!
*by A***M on February 12, 2017*

This heater works awesome !! I installed it myself in about 4 hours including cutting in a vent through the outside wall, but the gas line, power and thermostat wire were already roughed in from when I finished the garage in last summer, so I didn't have to run them while installing this heater. I had to use 1 1/2" slotted angle braces to hang it from the ceiling because I wanted it angled and mounted in the corner of my garage. The mounting holes in the heater's hanging brackets are not wide enough to mount it angled without putting additional blocking in the ceiling between standard 24" OC trusses, or using slotted angle braces like I did. I pulled a homeowner installation mechanical permit which added another $65.00 to the cost. I know a lot of people install them without a permit, but if something goes wrong and my garage burns down I don't want my insurance company to have ANY reason to try and get out of taking care of it. $65 is cheap peace of mind in my book and working with the inspector was very easy. I used 3" double wall B vent pipe and fittings sourced locally which are easy to work with and attach to this heater. I do think it's time for Modine to replace the ugly green/ grey color in favor of a more modern/ pleasing one like white, black or silver. They make a limited edition one that is black but it costs a lot more and I couldn't find it on Amazon. This thing looks like it was coated in prison colors lol !! I have a nice bright finished 3 car garage and this thing heats it up fast !! It just looks ugly. I am taking mine apart this spring once I don't need it anymore and having it powder coated white. The inspector and I both like its compact size and quiet operation. I used an Emersen UP310 programmable thermostat also from Amazon which works great and adds a fan only function which is nice if you want to circulate air without the heat on. I mounted the thermostat on a short partition wall shielded from the heaters air flow 12' away. It works great and keeps the heater from short cycling. My garage is properly insulated and drywalled and this heater can handle our Northern Idaho winter with ease, taking it from low 30's to low 60's in the garage in 15 to 20 minutes !! Once warmed up, it runs once an hour or so to keep the temp where I set it. What a difference !! Other than the cosmetics, this thing is great and I highly recommend it !! I only wish I had bought one sooner !!

### ⭐⭐⭐⭐⭐ It does a very good job of heating my 24' x 30' garage/ workshop
*by O***B on January 11, 2024*

I had a gas line ran around the side of my house to the back of the garage. Originally, I tried a non-venting wall hanging gas heater. NOPE! TOO MANY FUMES. Regardless of what I heard people saying . It will be fine. Just crack a window open won't be a problem. This Bodine Hot Dawg heater is the cats meow! I mounted it to the ceiling and had an installer hook it up the gas that is. I did the venting thru the wall and out just passed the overhang. Only purchasing the vent pipe and a thermostat, those were the only extras. You just can't take the cheap route. This heater is worth every penny I spent!

### ⭐⭐⭐⭐⭐ A quality product
*by R***H on March 6, 2025*

Easy to replace when you’re replacing the same unit 20 years later
