duces small amounts of carbon monoxide. Some
people are more affected by carbon monoxide than
others. Early signs of carbon monoxide poisoning
resemble the flu, with headaches, dizziness, and/or
nausea. If you have these signs, the heater may not

Propane gas is odorless. An odor-
Propane Gas:
making agent is added to propane gas. The odor
helps you detect a propane gas leak. However, the
odor added to propane gas can fade. Propane gas
may be present even though no odor exists.
This is a propane, direct-fired heater. Propane is
heavier than air. If propane leaks from a connection
or fitting, it sinks to the floor, collecting there with
the surrounding air, forming a potentially explosive
mixture. Obviously, propane leaks should be avoided,
so set up the propane supply with utmost care. Read
Propane/LP Safety, page 4 for additional informa-
tion about detecting propane leaks. Leak check new
connections or reconnections with a soap and water
solution and follow all connection instructions herein.
Also, ask your propane dealer for advice on the
propane application and supply installation and ask
them to check it if there are any questions.
When the heater is to be operated in the presence of
other people the user is responsible for properly ac-
quainting those present with the safety precautions
and instructions, and of the hazards involved.

ings. Keep this manual for reference. It is your
guide to safe and proper operation of this heater.
1. Check the heater thoroughly for damage. DO
NOT operate a damaged heater.
2. DO NOT modify the heater or operate a heater
