vented configuration. Check your state or local codes.

 

 

 

 

 

WARNING

 

Before installing in a solid fuel burning fireplace, the chimney flue

 

and firebox must be cleaned of soot, creosote, ashes and loose paint

 

by a qualified chimney cleaner. Creosote will ignite if highly heated.

 

Inspect chimney flue for damage. If damaged, operate heater with

 

flue damper closed.

 

 

 

 

 

WARNING

 

Seal any fresh air vents or ash clean-out doors located on floor or wall

 

of fireplace. If not, drafting may cause pilot outage or sooting. Use a

 

heat-resistant sealant. Do not seal chimney flue damper.

less than 36 inches from the front, top, or sides of the heater

CAUTION

 

This heater creates warm air currents. These currents move heat

 

to wall surfaces next to heater. Installing heater next to vinyl or

 

cloth wall coverings or operating heater where impurities in the air

 

(such as tobacco smoke) exist, may discolor walls.

 

 

 

IMPORTANT: Vent-free heaters add moisture to the air. Although this is benefi-

 

cial, installing heater in rooms without enough ventilation air may cause mildew

 

to form from too much moisture. See Air for Combustion and Ventilation, pages 5

 

through 8.

 

CHECK GAS TYPE

The heater utilizes advanced infrared heating technology, which ensures that radiant heat is emitted throughout the room.

This feature guarantees peace of mind for users, ensuring that safety is prioritized without sacrificing comfort.

Another significant characteristic of this heater is its realistic log design, which mimics the look of traditional wood-burning fireplaces. The ceramic fiber logs are intricately detailed, providing an authentic and charming ambiance that enhances any room's aesthetic. This realistic flame effect not only adds to the visual appeal but also creates a cozy atmosphere perfect for gatherings with family and friends.

The heater is designed to operate efficiently with minimal maintenance. The adjustable thermostat allows for precise temperature control, ensuring that users can set their desired warmth level and maintain it effortlessly. Moreover, the unit is compatible with natural gas, making it an environmentally friendly option that reduces the carbon footprint compared to traditional heating methods.

In summary, the Desa Unvented Natural Gas Log Heater is an exceptional heating option that combines elegance, safety, and performance.
