OPERATION

Propane Supply / Information
Propane (LP)
This heater is not supplied with a propane cylinder. Use only
an approved propane cylinder.
LP Characteristics
• Flammable, explosive under pressure, heavier than air
and pools in low areas.
• In its natural state, propane has no odor, but for your
safety an odor that smells like rotten cabbage has been
added.
• Contact of propane (LP) gas with the skin can cause
freeze burns.
• Heater is manufactured for use with propane gas only.
DO NOT attempt to convert to any other gas. Such
modifications are dangerous and will void the warranty.
• When heater is not in use, LP Cylinder must be turned
OFF.
• Be sure that the LP Cylinder is located on a level and
stable surface.
• DO NOT use this heater in a basement or below ground
level. Propane is heavier than air and will always seek
the lowest level. If you suspect a leak, shut off the valve
at the LP Cylinder immediately.
The Propane (LP) cylinder must also be equipped with
the following:
• A collar to protect the gas valve.
• A shut-off valve terminating a LP cylinder valve outlet
as specified in the American National Standard for
Compressed Gas Cylinder Valve Outlets and Inlets
Connections.
• A safety relief valve having direct communications with
the vapor space of the LP cylinder.
• The heater must operate on vapor withdrawal from the
operating cylinder.
The amount of Propane (LP) used with this heater
varies. Both factors are:
• The amount of gas in the cylinder of LP.
• The temperature of the LP tank and its surroundings.

The table above shows the minimum number of 100 lb.
(45 kg) LP cylinders required in cold weather. Your local LP
dealer will help you select the proper LP supply system.
• Always keep LP cylinder fastened and upright.
• Avoid tipping the LP cylinder on its side when
connected to a regulator, since this may cause damage
to diaphragm in the regulator.
• Handle valves with care.

• Never connect an unregulated LP cylinder to a
construction heater.
• DO NOT subject LP cylinder to excessive heat.
• Tightly close the gas shutoff valve on the LP cylinder
after each use.
• All fittings must be protected when disconnected from
the LP cylinder.

CAUTION: The disconnected tank must never be
stored in a building, garage, or any other enclosed
area.
Pre-Lighting Instructions

WARNING: Purging and filling of the LP cylinders
must be performed by personnel who have been
thoroughly trained in accepted LP gas industry
procedures. Failure to follow these instructions may
result in explosion, fire, severe personal injury or death.
Connecting the LP Cylinder

All new LP cylinders must be purged before the first
filling.
• Turn heater gas valve knob and LP cylinder valve to OFF
position.
• LP cylinder valve equipped with old style fitting has
LEFT HANDED THREADS. Turn fitting CLOCKWISE to
loosen. Protect this fitting when disconnected from LP
cylinder.
• Have your LP cylinder filled by your local propane gas
supplier.
• Some LP cylinders have a bleed-OFF valve. This valve
should be inspected for leaks after each filling of the LP
cylinder. Turn the valve clockwise to close.
• Fasten full propane tank and connect proper fitting to
LP cylinder valve by turning COUNTER-CLOCKWISE (see
Figure B & C).
• With heater gas valve knob still in OFF position turn
ON the LP cylinder valve and check for leaks with soap
solution.

Checking for Leaks
• To check for leaks, make up a 50/50 solution of
dish soap and water. Apply this solution to all gas
connections. If bubbles appear, there is a leak.
