Dayton / Sterling QVF Gas Unit Heater Information
(for propane and natural gas heaters)
Back to Sterling Heaters Pricing Page

Heat Exchanger
Airfoil contoured dimpled tubes allow expansion and contraction stresses to flow out evenly across the heat exchanger tubes. There are no ridges or sharp bends in the tubes where stresses can concentrate to cause early heat exchanger failure through metal fatigue. Operational noises during warm-up and cool down are also minimized by the tube design. Heat exchangers are die formed from corrosion and rust resistant 20 gauge aluminized steel.

Burner
Corrosion resistant aluminized steel with slotted, oversized ports and stainless steel separator strip to help prevent clogging and reduce maintenance. Sterling's ribbon style burners are unique because multiple burners are used for each heater. This feature greater reduces replacement cost and installation time if one stops working properly.

Enclosure
Aluminized steel with baked-on gray powder paint finish. Hinged bottom pan allows access to burner and pilot assembly. Removable side panels enables maintenance and suspension point adjustment.

Standard Controls
115 volt power supply and 25 volt controls. Limit control shuts off main burner to prevent overheating. Single stage standing pilot ignition with safety redundant gas valve. 100% safety shut-off.
