The gas-fired Hot Dawg® offers the following features:

• Hush-puppy quiet operation
• 10 year warranty on heat exchanger
• Lightweight, easy installation
• Low profile design
• Certified for residential, commercial and industrial use

All PTS/BTS units are packed with features to deliver maximum comfort:

• Swept wing fan on sizes from 100,000 to 200,000 BTU's/hr for superior airflow and noise reduction where it's needed most.
• In-shot burners fire each heat exchanger tube for reliable performance, ease of service and decreased noise on ignition.
• Same-size vent and combustion air inlets throughout product line makes installation easier.
• Optional stainless steel heat exchanger.
• Centrifugal blower models with adjustable sheaves for wide airflow range (BTS line).

• A long-life heat exchanger is made of corrosion-resistant, aluminized steel and roll-formed to eliminate thermal stress. It contains a preformed, ceramic fiber fire-pot that is lightweight, resilient, and resists bothe mechanical and thermal shocks.
• For ease of service, the heat exchanger is equipped with an inspection port, two cleanout ports, and an amply-sized service door for removing fire pot when replacement becomes necessary.
• A reliable, pressure-atomizing gun-type burner equipped with a stainless steel, die-stamped flame-retention head that can increase combustion efficiency by as much as 20 to 30 percent over non-flame retention-type burners.
• Honeywell microprocessor based ignition controller providing superior combustion and safety monitoring.
• Onboard diagnostics with LED output for simplifying the lives of service personnel.
