Many of our customers happily report that purchasing a Hot Dawg heater from the Greenhouse Megastore helped them save 50% or more off the unit price received from a local HVAC installer. However, for safety reasons and to minimize installation problems Modine strongly recommends having a licensed HVAC technician install your Hot Dawg heater. Although we are happy to offer limited technical support for your Hot Dawg purchase, we can NOT install the heater for you over the phone nor are we able to troubleshoot problems you may experience if you choose to install the heater yourself. By purchasing this heater from us, you accept sole responsibility for installation and agree to abide by Modine's limited Warranty.
Based on our experience in selling Modine Hot Dawg Heaters, we have written up a troubleshooting guide that deals with the issues we most commonly hear from customers. - Troubleshoot a Modine Hot Dawg

It is the customer's responsibility to carefully inspect heaters for damage before accepting delivery since heaters are usually not returnable once delivery is accepted. Obviously damaged heaters should be refused and Greenhouse Megastore customer service contacted to make arrangements for a replacement unit. Once delivery is accepted Greenhouse Megastore will gladly provide replacement parts under the manufacturer's warranty to repair damaged or defective heaters; however this warranty does not include any labor costs associated with installing these parts. Warranty issues should be diagnosed by a certified HVAC technician since parts deemed not to be defective by the manufacturer are not available for credit back to the customer. Specific warranty policies vary by manufacturer but typically cover replacement parts as indicated above up to one year after purchase. Please contact Greenhouse Megastore customer service if you have any questions about the warranty for your specific heater.

The product is first rate, fired up cleanly after a test purge of the lines. Not noisy. Warming up a 20 2+ car garage is challenging it, and I might have wished I chose a larger version. Greenhouse was super to work with, keeping me informed of the shipping delays and when it was shipping. Outstanding customer service. Thank you Greenhousemegastore.
Received my heater within days of ordering. Arrived well packed. Haven't installed yet, but looking forward to using replacing a 50 year old heater...
I have not installed the Modine 45 yet. the only bad thing i have to say about that is there is no instructions on how to hook up the thermastat . The add-on accessory kit is not worth the purchase. The sheet metal ducts will come somewhat bent up and they are not full pipe. you to roll them up and crimp them at the seam. What a waste of natural resources, money and time. After trying to work with that "piping" for quite some time and never being able to get the sheet metal to become a pipe like the picture shows. I'm going to the hardware store and buy the true vent pipe ready to work with. Also regarding the gas vent hardware - you need a T for clean out and drip. As far as the gas pipe hardware they are really of no value. you need a long ( 6"? ) nipple coming out of the gas valve into a T with a 3"min trap and cap. All of this is in the Modine manual. you will need to go online and look for how-to videos and see what you need. So far the heater gets a 4 but the add-on package gets a 1 - for a combined rating of 3
I bought this unit 3 years ago and installed it in my 24 X 30 two car, two story garage. I have a stair case in the back leading up to the second floor. I live in Southwestern PA and this unit runs from Nov. to April. I have the thermostat set at 65 all the time and it heats both floors without any problem. I wanted to wait before I posted my review and this unit is the absolute best thing I ever bought on line. I highly recommend this to any one debating on if they should buy one. Excellent product Hot Dawg, I recommend this unit to everyone I know looking for a great heater.
Super easy to install. Works great at 8000ft elevation.
Unit has been installed for a month. Heats a 2.5 car garage with a loft no problem. Every thing works as it should. Nice strong fan and fairly quite as well.
