PROPANE SUPPLY
PROPANE
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 the 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 be equipped with the
following:
• A collar to protect the gas valve.
• A shut-off valve terminating an LP cylinder valve outlet
as specified in the American National Standard for
Compressed Gas Cylinder Valve Outlet and Inlet
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.
