R75-58R

• Remanufactured with 100% pure, solid silver Pyrostat contacts for longer on-the-job service life
• Backed by 2-year warranty
• All new stack relays contain brass contacts covered with a slight silver plating, it wears off as the contacts open and close, exposing the brass surface over time, the exposed surface is a poor conductor and may result in relay failure and nuisance callbacks
  
  

  R5R

Interrupted ignition type
• Combine a Protectorelay unit for cycling the burner and a Pyrostat flame detector for sensing temperature changes of flue gases up to 1000 deg F
• Manual reset of safety switch required after ignition failure completely shuts off main burner
• Include manual trip safety switch to assure burner shutdown during servicing
• Mount with flange for mounting on curved or flat surfaces
• Works with 2-wire and 3-wire 24 VAC thermostat
• 2 years warranty
