4. Open propane supply valve on propane
tank(s) slowly.
Note:
If not opened
slowly, excess-flow check valve on pro-
pane tank may stop gas flow. If this
happens, close propane supply valve
and open again slowly.

(48 and 138 kPa) (see Figure 5).
Note:
Higher regulator setting will allow
heater to produce more heat.
PROPANE SUPPLY
Propane gas and propane tank(s) are to be
furnished by the user.
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 li-
brary or fire department will have this book-
let.
The amount of propane gas ready for use
from propane tanks varies. Two factors de-
cide this amount:
1. The amount of propane gas in tank(s)
2. The temperature of tank(s)
The chart below shows the number of 100-
pound (45 kg) tanks needed to run this
heater.
Do not operate this product with any tank
smaller than 100 pounds (45 kg).
Temperature °F(°C)
No. of Tanks
At Tank 100 lb.(45 Kg)
40 (4.4) 3
32 (0) (Use larger tank
below 40°F [4.4°C])
20 (-6.7) (Use larger tank
below 40°F [4.4°C])

below 40°F [4.4°C])
-10 (-23) (Use larger tank
below 40°F [4.4°C])
-20 (-29) (Use larger tank
below 40°F [4.4°C])
Less gas is vaporized at lower temperatures.
You may need a larger tank in colder weather.
Your local propane gas dealer will help you
select the proper supply system. The mini-
mum surrounding air temperature rating for
each heater is -20°F (-29°C).
