Gemini￿ Twin-Fuel Gas-Fired Boiler

2.0DESCRIPTION

2.1PRINCIPLE OF OPERATION

Natural gas and propane are permanently piped to separate connections on the boiler. Each branch of the gas train is fitted with a regulator and a motorized gas valve. The regulators are adjusted to properly fire the boiler from their respective sources. Boiler and con- trol functions are the same for both fuels.

In the event of interruption or restriction of the natural gas supply, changeover to propane is made manually

by a selector switch on the boiler (or by a signal from a remote switch or controller).

When the natural gas supply is reestablished, change- over is made by restoring the selector switch to its normal position (or by sending the appropriate signal from the remote controller).
