Minimum Noncombustible Material Clearances

If Not Using Mantel

Note: If using a mantel, proceed to If Using Mantel. If not using a mantel, follow the information below.

You must have noncombustible material(s) above the fireplace opening. Noncombus- tible materials (such as slate, marble, tile, etc.) must be at least 1/2 inch thick. With sheet metal, you must have noncombustible material behind it. Noncombustible mate- rial must extend at least 8" up (for all mod- els). If noncombustible material is less than 12", you must install the fireplace hood accessory (24", 30" and 36" models only). See Figure 5 for minimum clearances.

IMPORTANT: If you cannot meet these minimum clearances, you must operate heater with chimney flue damper open. Go to Installing Damper Clamp Accessory for Vented Operation, page 10.

If Using Mantel

With sheet metal, you must have noncombustible material behind it. Noncombustible mate- rial must extend at least 8 inches up (for all models). If noncombustible material is less than 12", you must install the fireplace hood accessory (24", 30" and 36" models only). Even if noncombustible material is more than 12", you may need the hood accessory to deflect heat away from your mantel shelf. See Figure 5 and Figures 6 and 7 on page 9 for minimum clearances.

IMPORTANT: If you cannot meet these minimum clearances, you must operate heater with chimney flue damper open. Go to Installing Damper Clamp Accessory for Vented Operation, page 10.

GAS LOG HEATER specifications

Desa GAS LOG HEATER is a popular heating solution that brings the warmth and ambiance of a traditional fireplace to modern living spaces. Renowned for its efficiency and aesthetic appeal, this gas log heater is designed to replicate the flickering flames and the cozy feel of a wood-burning fire without the associated hassles.

One of the primary features of the Desa GAS LOG HEATER is its realistic flame effect, which is created using advanced gas log technology. The heater utilizes artificial logs that are crafted to resemble real wood, enhancing the visual appeal and creating a nostalgic atmosphere. The flames are adjustable, allowing users to customize the intensity based on their preferences and heating needs.

Efficiency is a hallmark of the Desa GAS LOG HEATER. Equipped with a high-efficiency heating system, it effectively converts gas to heat, ensuring that energy consumption is kept to a minimum. This results in lower utility bills and a reduced carbon footprint, making it an environmentally friendly option for homeowners. The heater's BTU output can vary, allowing it to accommodate different room sizes and layouts.

The Desa GAS LOG HEATER also features easy ignition systems, which simplify the startup process. Many models come with an automatic ignition option or a push-button start, eliminating the need for matches or lighter. Furthermore, they often include adjustable heat settings, enabling users to control the temperature easily.

Safety is a critical concern with gas heaters, and Desa addresses this with built-in safety features. These may include safety shut-off valves, thermocouple sensors, and automatic shut-off systems that activate in case of malfunction or if the heater tips over. This provides peace of mind for families with children or pets.

Installation of the Desa GAS LOG HEATER is generally straightforward, especially compared to traditional wood-burning fireplaces. Many units can be vented directly through an exterior wall, reducing the need for extensive chimney systems. This versatility allows homeowners to place the heater in various locations, enhancing the overall design of their spaces.

In summary, the Desa GAS LOG HEATER combines style, efficiency, and safety to deliver a reliable heating solution.
