27. GAS CONVERSION OF BURNERS
Tube Heater Burners are factory produced and supplied to operate on natural gas.
100,000 Btuh input model is available in natural gas only and is not convertible to propane gas.
For models with inputs 60,000, 80,000, 110,000, 130,000, and 150,000 Btuh a field conversion
kit is available to convert from natural gas to propane gas, or vice versa. Refer to the table be-
low for kit part numbers. Each kit contains the specific instructions required to install the kit.
Models with inputs 175,000 and 200,000 Btuh are field convertible between gas types, but
the conversion is relatively more extensive and expensive than lesser input models. When or-
dering, Model & Serial Numbers are required. For inputs 175,000 and 200,000 it is recom-
mended that the burner be ordered and factory produced for the specific type of fuel gas using
