INFORMATION

 

 

 

 

 

 

 

 

 

IMPORTANT: Read this owner’s manual carefully and completely

 

 

 

 

 

 

before trying to assemble, operate, or service this heater. Improper

 

 

 

 

 

 

use of this heater can cause serious injury or death from burns, fire,

 

 

 

 

 

 

explosion, electrical shock, and carbon monoxide poisoning.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

DANGER

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Carbon monoxide poisoning may lead to death!

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Carbon Monoxide Poisoning: Early signs of carbon monoxide poisoning

 

 

 

 

 

 

resemble 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, persons 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.
