NATURAL GAS HEATER

VANGUARD VN6C AND VN10

Carbon Monoxide Poisoning:

 Early

signs of carbon monoxide poisoning re-
semble the flu, with headaches, dizziness,
or nausea. If you have these signs, the heater
may not be working properly. Get fresh air
at once!
 Have heater serviced. Some people
are more affected by carbon monoxide than
others. These include pregnant women, per-
sons with heart or lung disease or anemia,
those under the influence of alcohol, and
those at high altitudes.

Natural Gas:

 Natural gas is odorless. An

odor-making agent is added to natural gas.
The odor helps you detect a natural gas leak.
However, the odor added to natural gas can
fade. Natural gas may be present even though
no odor exists.

Make certain you read and understand all
Warnings. Keep this manual for reference.
It is your guide to safe and proper operation
of this heater.
