The chart below shows the minimum num- ber of 100-pound tanks needed to run the heater. Connect tanks together with a mani- fold. Do not operate this product with any tank smaller than 100 pounds.

Less gas is vaporized at lower temperatures. Two or more 100-pound tanks or one larger tank may be needed in colder weather. Your local propane gas dealer will help you select the proper supply system.

NATURAL GAS

SUPPLY

(FOR MODEL TC100VRNA)

You must provide the natural gas supply and the connections to the heater.

The natural gas supply must have a capacity of 100 scfh at 6 inches water column to 14 inches water column.

Consult your natural gas supplier for proper sizing of the natural gas supply lines.

THEORY OF

OPERATION

The Fuel System for Propane: The hose/ regulator assembly attaches to the propane gas supply. This provides fuel to the heater.

The Fuel System for Natural Gas: The gas supply attaches to the heater by a minimum 3/4 inch i.d. hose or flexible connector. User must supply hose or flexible connector. The length should be no more than 10 feet long. The natural gas moves through the regulator and out the nozzle.

The Ignition System: The piezo ignitor lights the pilot fuel supply.

The Automatic Control System: The auto- matic control valve shuts off the heater if the flame goes out.

PROPANE SUPPLY

(FOR MODEL TC100VR)

You must provide propane gas and propane tank(s).

Use this heater only with a propane vapor withdrawal supply system. See Chapter 5 of the Standard for Storage and Handling of Liquefied Petroleum Gas, ANSI/NFPA 58 and/or CAN/CGA B149.2. Your local library or fire department will have this booklet.

The amount of propane gas ready for use from propane tanks varies. Two factors de- cide this amount.

1.The amount of liquid propane gas in tank(s)

2.The temperature of tank(s)

Follow all local ordinances and codes. In the absence of local ordinances and codes, refer to the National Fuel Gas Code Handbook, NFPA54/ANS Z223.1 and the Natural Gas Installation Code, CAN/CGA B149.2.
