a vent or up a chimney. Heat is generated by realistic, dancing yellow flames. This

 

 

 

 

heater is designed for vent-free operation with flue damper closed. State and local

 

 

 

 

codes in some areas prohibit the use of vent-free heaters. You can operate heater as

 

 

 

 

a vented product by opening flue damper.

COMBUSTION

 

 

 

 

 

 

 

 

 

This heater shall not be installed in a confined space unless

 

 

 

AND

 

 

provisions are provided for adequate combustion and ventila-

 

 

 

 

 

tion air. Read the following instructions to insure proper fresh

air for this and other fuel-burning appliances in your home.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Today’s homes are built more energy efficient than ever. New materials, in-

 

 

 

 

 

 

creased insulation, and new construction methods help reduce heat loss in homes.

 

 

 

 

Home owners weather strip and caulk around windows and doors to keep the cold

 

 

 

 

air out and the warm air in. During heating months, home owners want their

 

 

 

 

 

 

homes as airtight as possible.

 

 

 

 

 

 

While it is good to make your home energy efficient, your home needs to breathe.

 

 

 

 

Fresh air must enter your home. All fuel-burning appliances need fresh air for

 

 

 

 

 

 

proper combustion and ventilation.

 

 

 

 

 

 

Exhaust fans, fireplaces, clothes dryers, and fuel burning appliances draw air

 

 

 

 

 

 

from the house to operate. You must provide adequate fresh air for these appli-

 

 

 

 

 

 

ances. This will insure proper venting of vented fuel-burning appliances.

The Desa Unvented (Vent-Free) Natural Gas Log Heater is an innovative heating solution that combines efficiency, comfort, and aesthetic appeal. Designed for those seeking a reliable and stylish way to heat their living spaces, this vent-free heater is ideal for any home setting.

One of the main features of the Desa Unvented Gas Log Heater is its ability to provide warmth without the need for external venting. This means it can be installed in a variety of locations, including areas without a traditional chimney or flue. The absence of vents not only simplifies installation but also maximizes design flexibility, allowing homeowners to enhance their existing decor with a beautiful gas log fireplace.

The heater utilizes advanced infrared heating technology, which ensures that radiant heat is emitted throughout the room. This method of heating is exceptionally efficient, as it warms up objects and people directly, rather than merely heating the air. Consequently, this results in faster heating times and greater comfort, especially during colder months.

Equipped with the latest safety features, the Desa Unvented Gas Log Heater includes an oxygen depletion sensor (ODS), which automatically shuts off the heater if oxygen levels drop too low. 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. With its vent-free design, advanced heating technology, realistic aesthetics, and user-friendly features, this heater is a perfect choice for those looking to create a warm and inviting environment in their homes.
