Product Details
Product Details
- Thermal efficiency of 80% means lower operating costs
- Fan assisted combustion - the blower is built into the low Nox burner assembly
- A stainless steel air flapper is used inside the premix system to replace externally mounted flue damper to minimize the standby heat loss and to minimize the overall heater height
- Metal venting - rated category I appliance and uses standard double wall type "B" vent
- Permaglas® Ultra Coat™ is applied after the complete tank has been assembled to give a seamless barrier against hot water corrosion
- Uses a smaller vent diameter than a natural draft water heater which saves on installation cost
- Fully automatic digital controls with safety shutoff
- Foam insulation saves fuel, helps reduce standby heat loss
- Intermittent ignition device eliminates standing pilot , provides flame failure response in less than one second and has a spark ignitor and power on/off switch
- Three-year limited tank and 1-year limited parts warranty
