Theory of Operation
The Fuel System: The hose/regu-
lator assembly attaches to the
propane gas supply. This pro-
vides fuel to the heater.
The Ignition System: The piezo
ignitor lights the pilot.
The Automatic Control System:
This system causes the heater to
shut down if the flame goes out.
Propane Supply
Propane gas and propane tank(s)
are to be furnished by the user.
Use this heater only with a
propane vapor withdrawal sup-
ply system. See Chapter 5 of
the Standard for Storage and
Handling of Liquefied Petroleum
Gas, ANSI/NFPA 58. 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 propane
gas in tank(s)
2. The temperature of tank(s)
