HOT DAWG® SEPARATED COMBUSTION GAS-FIRED UNIT HEATER (MODEL HDS) Same features as HD, with these added benefits:
• Draws combustion air from outside the work space, ensuring the unit always has plenty of fresh, clean air to breathe
• The fresh air supply reduces common concerns about dusty, dirty or humid applications, providing greater durability and reduced maintenance
• Factory assembled, certified separated combustion saves installation time
HOT DAWG® POWER-EXHAUSTED, GAS-FIRED UNIT HEATER (MODEL HD)
• Hush-puppy quiet operation (see table)
• Right or left hand controls available on all 30-75 units. Gas, electrical and flue connections can be changed by simply flipping the Hot Dawg over
• Uses natural or propane gas
• Lightweight, easily installs 1” from ceiling with only two angle brackets (included on sizes 30-75, accessory for 100, 125)
• Full 10-year warranty on heat exchanger
• Standard power exhaust simplifies side-wall or roof venting with small-diameter vent pipe
• Permanently-lubricated motor for trouble-free dependability
• Controls can be either single or two-stage, direct spark ignition, 100% shut-off with continuous retry
• Low-profile design and neutral color to blend in with decor
• Also available with a blower (model HDB). Contact Modine for further information
HOT DAWG® H2O LOW PROFILE HOT WATER UNIT HEATER (MODEL HHD)
• No external moving parts - twin centrifugal blowers keep all moving parts inside the cabinet
• Mounting flexibility (parallel, perpendicular or recessed between joists) allows for horizontal or vertical air delivery
• Low-profile design
• Available in hammertone beige
• Constructed of heavy gauge steel for clean appearance and maximum headroom
• Includes two mounting brackets with vibration isolators to reduce noise and vibration
• Internal coil can handle water pressures up to 150 PSI and temperatures up to 200° F

EFFINITY 93® CONDENSING UNIT HEATER (MODEL PTC)Looking for the most efficient unit?All model sizes operate at 93% efficiency, making it the most efficient gas-fired, condensing unit heater in North America
Features Modine’s high-grade stainless steel Conservicore® technology secondary heat exchanger
All sizes are separated combustion
The standard Contractor Convenience Package allows for easy connectivity and troubleshooting with a factory mounted disconnect switch, external operating lights and convienience outlet
A minimum 15% decrease in C02 versus other gas-fired heaters and minimum 17% gas savings (up to 40%)
A smart investment and respectable ROI with valuable state utility rebates available
Performance Data - Model PTC
1. Ratings shown are for elevations up to 2,000 ft. For elevations above 2,000 feet, ratings should be reduced at the rate of 4% for each 1,000 feet about sea level. (In Canada see rating plate.) Reduction of ratings requires use of high altitude kit.
2. Data taken at 65ºF ambient and unit fired at full-rated input. Mounting height as measured from bottom of unit, and without deflector hoods. ˆ
* Requires a 40 degree ambient temperature at all times and access to a drain for condensate
