WARNINGS

INFORMATION

IMPORTANT: Read this owner’s manual carefully and completely be-

fore 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.

WARNINGS 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 operating or venting properly. Get fresh air at once! Have heater or heater venting system serviced. Some people are more affected by carbon monoxide than others. These include pregnant women, people 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.

1.A qualified service person must install heater and venting system.

2.Use only natural gas. Do not convert heater to use different fuel type.

3.If you smell gas

•Shut off gas supply.

•Do not try to light any appliance.

•Do not touch any electrical switch; do not use any phone in your building.

•Immediately call your gas supplier from a neighbor’s phone. Follow the gas supplier’s instructions.

•If you cannot reach your gas supplier, call the fire department.

4.This heater must have fresh air for proper operation. If not, poor fuel combustion and improper venting of flue gases will result. Carbon monoxide poisoning from backed-up flue gases could occur. The State of California lists carbon monoxide as a reproductive toxin under Proposition 65. Read the instructions under Fresh Air for Combustion and Ventilation, pages 16 through 19 for complete information.

5.Never install the heater

•in a mobile home or a recreational vehicle.

•where curtains, furniture, clothing, or other flammable objects are less than 48 inches from the front, 53 inches from top, or 12 inches from right side and 6 inches from left side and back of heater.

•directly on carpeting, tile, or other combustible materials other than wood flooring. Place heater on metal or wood panel extending the full width and depth of heater.
