Modine's HDC series features a blower type fan for increased air flow performance over traditional propeller units in a separated combustion configuration. The higher CFM ratings of these units make them a perfect solution for warehouses, large garages or workshops where heat needs to be thrown a long distance while drawing combustion air from the outside for dusty or humid applications.
Less maintenance in dusty environments.
Improved efficiency by using outside air for combustion.
Greater durability in "hostile" environments (environments possessing substances that may deteriorate the performance of the unit).
External thermostat and gas connections.
Hush-puppy quiet operation.
Uses natural or propane gas.
Certified for residential, commercial and industrial use.
Low-profile design and neutral color to blend in with decor.
Lightweight, easily installs 1" from ceiling with only 2 angle brackets (included).
Install quickly and easily with field wiring connections and knockouts for quick access to gas and electricity.
Standard power exhaust simplifies side-wall or roof venting with small-diameter vent pipe.
Versatile design allows for right or left hand controls and installation. Gas, electrical and flue connections can be changed from one side to the other by simply flipping the Hot Dawg over.
Permanently-lubricated motor for trouble-gree dependability.
Full 10-year warranty on heat exchanger.
100% Outside Air for Combustion
Sealed Compartment Protects Combination Gas Control
*Do not locate any gas-fired unit in areas with chlorinated, halogenated or acidic vapors in atmosphere.
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.

Heater Warranty and Return Policy
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.
