THEORY OF OPERATION
The Fuel System for Propane:
The hose/regulator assembly at-
taches 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 ignitor lights the pilot fuel supply.
The Automatic Control System:
The automatic 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 decide this amount.
1.
The amount of liquid propane gas in tank(s)
2.
The temperature of tank(s)
The chart below shows the minimum number of 100-pound tanks
needed to run the heater. Connect tanks together with a manifold. 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.
