Unconfined Space An unconfined space whose volume is not less than 50 cubic feet per 1,000 BTU/HR of the aggregate input rating of all appliances installed in that space. Rooms communicating directly with the space in which the appliances are installed, through openings not furnished with doors are considered a part of the unconfined space. Confined Space A confined space whose volume is less than 50 cubic feet for each 1,000 BTU/HR of the aggregate input rating of all appliances in that space.

SOLVING COMMON PROBLEMS The 3 most common problems associated with any gas heater are gas leaks, wrong gas pressure and dirt. Do Not Use Your Heater Without Checking For Leaks! Leaks can occur during shipment and installation. A simple solution of soap and water dabbed on the fittings will bubble if a gas leak is present. Do not take short cuts! Wrong Gas Pressure! Too much gas pressure may severely damage your heater. Too little gas pressure and your heater will not burn correctly.
