HeatStar ERXL125-N Owner's manual

  • Hello! I've reviewed the Heatstar ERXL Operating Instructions and Owner's Manual. This document provides essential guidance on the installation, operation, and maintenance of the Heatstar ERXL series of gas-fired, low-intensity infrared heaters designed for both residential garages and commercial applications. The manual contains information about the heater's hot surface ignition system, venting requirements, gas piping, and wiring. I am ready to assist you with any question you have about this manual and the Heatstar ERXL models described within it.
  • What should I do if I smell gas?
    What is the recommended gas pressure at the manifold for natural gas?
    What is the maximum allowable length for the vent?
    What is the recommended vent pipe diameter?

Operation & Maintenance
Sequence of Operation
1. Turnthethermostatup.Whenthethermostatcallsforheat,
