INTRODUCTION This manual provides information necessary for the installation, operation, and maintenance

of the micro-boiler. The model description is listed on the rating plate which is attached to the side panel of the

micro-boiler. Please read all installation instructions completely before installing this product. If you have any problems or questions regarding this equipment, consult the manufacturer or

its local representative. These high efficiency models have a built-in secondary heat exchanger that absorbs latent

heat from the exhaust gas. The principle behind condensing micro-boilers is simple:

*This diagram illustrates condensing micro-boiler design concepts only and does not accurately represent the micro-boilers physical description.

1. Your thermostat indicates a need for heat and turns on a circulator pump.2. Water enters the boiler.3. The water flow sensor detects the water flow.4. The computer initiates the fan motor and sends a signal to the igniter to create an ignition spark.5. The gas ignites and flames appear within the burner chamber.6. Water circulates through the heat exchanger and then gets hot.7. Using thermistors to measure temperatures throughout the micro-boiler,
