local authorities can advise you about these.
Carbon Monoxide Poisoning:
Some people are
more affected by carbon monoxide than others.
Early signs of carbon monoxide poisoning re-
semble the flu, with headaches, dizziness and/or
nausea. If you have these signs, the heater may not
be working properly.
Get fresh air at once!
Check
for proper ventilation and have heater serviced.
Propane Gas:
Propane gas is odorless. An odor-
making agent is added to propane gas. The odor
helps you detect a propane gas leak. However, the
odor added to propane gas may fade. Propane gas
may be present even though no odor exists.
Make certain you read and understand all warn-
ings. Keep this manual for reference. It is your
guide to safe and proper operation of this heater.
1. Install and use heater with care. Follow all
local ordinances and codes. In the absence
of local ordinances and codes, refer to the
Standard for Storage and Handling of Lique-
fied Petroleum Gas, ANSI/NFPA 58
and the
Natural Gas Installation Code, CAN/CGA
B149.2
. This instructs on the safe storage and
handling of propane gases.
2. Use only the electrical voltage and frequency
specified on model plate.
3. The electrical connections and grounding of
the heater shall follow the
National Electric
Code, ANSI/NFPA 70
or the
Canadian Electri-
cal Code, Part 1
.
4. Electrical grounding instructions — This appli-
ance is equipped with a three-prong (ground-
ing) plug for your protection against shock
hazard and should be plugged directly into a
properly grounded three-prong receptacle.
5. Use only a three-prong, grounded extension
cord.
6. Use only the hose and factory preset regulator

doors.

bustible materials, gasoline, paint thinner and
other flammable vapors and liquids. Do not
use heater in areas with high dust content.
