# The World’s Most Efficient and Versatile Fireplace The Mantis exceeds 90% efficiency – which means it uses about 35 percent less fuel compared to any other vented heater or fireplace system per Btu of heat in your room. This makes Mantis the greenest fireplace you can buy. Because its inexpensive 1 1/2-inch PVC vent pipe can be run inside a conventional 2 x 4 framed wall, the Mantis costs less to install – in materials, time, and labor. The Mantis is the first and only vented fireplace that adds humidity to the dry winter air, making your home feel warmer and more comfortable.The Mantis comes in two versions. The new flatfront Mantis Fireplace comes in three models with vent kits to allow installation in a wall, in a mantel, or as an insert in an existing wood-burning fireplace. The Mantis Bay Window comes in three models for installation in a mantel, as an insert, or on a pedestal. 

# Green Heating with Gas According to the US Environmental Protection Agency, heating with any gas appliance generates far less particulate pollution than heating with any other common fuel. The worst polluter, a wood fireplace, generates 28 pounds of particulates (measuring 2.5 microns or more) for every million Btu of fuel you put in. Heating with gas generates a tiny fraction of that (just 0.0083 pound) for every million Btu input. Compared to an EPA-certified wood stove, gas heat still generates less than 1 percent of the particulate pollution. And gas produces less than 2 percent of the pollution emitted by a pellet stove.

# What Makes Mantis Unique? Inside the Mantis a three-stage heat exchanger sends more than 90 percent of the heat energy into your home – not up the flue. While the temperature inside the combustion chamber may exceed 900 degrees F, the exhaust gas exits the flue at just 120 to 130 degrees F – as little as two feet away! This makes Mantis the first and only condensing fireplace, which means the exhaust is cool enough to run in PVC. Using PVC for venting makes the total installed price (unit, labor, and materials) comparable to a direct-vent fireplace or pellet stove. The Mantis puts the green in environmentally friendly. Its power-vented heat-exchanger technology ensures the optimal air/fuel mixture for consistently clean-burning operation. With its clean burn and super-efficient heat exchanger, the Mantis generates fewer greenhouse gases – CO and CO 2 

### . The top and sides of the Mantis stay cool-to-the-touch – so cool, in fact, it earned a zero-clearance certification for installation against any combustible building materials. The dual burners deliver a total of 28,000 Btu. Operating the front burner alone lets you enjoy the ambiance of the attractive log set and gas fire without overheating the room. But, when the temperature dips, the Mantis rises to the occasion, switching on the second burner to produce maximum heat output.

### If the Mantis is so efficient, why does it not carry an Energy Star rating? Mantis is so new to the U.S. market, it fits no current Energy Star category, however, it outperforms most Energy Star rated central furnaces in heat transfer efficiency. (The Mantis does not fit the furnace classification because it does not need “ductwork” to convey the heated air. Ironically, a central furnace’s ductwork contributes to heat loss.) In Australia, however, where this technology was originally developed, the Mantis earns a 5.52 out of 6 on that country’s Star Rating system. No vented zone heating system – U.S. or Australian – outperforms it. 

# Developed in Australia more than 10 Years Ago Patented Design – Worldwide

Australia’s Star system graphically represents heat transfer efficiency. The red and orange areas represent area of 1,500-sq ft room heated after one hour at 28,000 Btu/H input in Independent Laboratory Testing. For comparison, a typical 60-percent AFUE system would rate just three stars.



### The American Heating and Refrigeration Institute is working with the U.S. Department of Energy to create an Energy Star category for gas-fired zone heating products.

# Advanced Technology and Solid-State Controls The sophisticated control system monitors every critical aspect of the Mantis’ operation to maximize efficiency, comfort, and safety. For all its advanced technology, the Mantis is amazingly easy to operate. Two on/off buttons control the two burners, allowing you to set the temperature to low (front only), medium (rear only) or high (both burners). Or, choose one of the optional external controls, such as the programmable thermostat, and let your Mantis deliver the right amount of heat for each day of the week and time of the day. The Mantis automatically purges unburned gas from the combustion chamber for 40 seconds before each ignition for controlled, even starts every time. The modern, hot-surface ignit

ors conserve gas by eliminating the need for a standing pilot. The three-speed automatic circulating fan cycles on only after the Mantis reaches operating temperature and continues blowing as long as it senses warm air. You never feel a cool draft – just warm, humidified air.

### Inside the Mantis, separate systems create the heat and distribute the heat, so room air stays isolated from the combustion process. 

## Creating the Heat (White, Black and Gray Arrows) (A) The power vent blower draws in outdoor air (White Arrow) via the PVC intake pipe. (B) Inside the fireplace the three-stage burner, below the log set, mixes the air and gas (LP or natural) and burns it to produce heat. (C) The power vent blower extracts the hot combustion gases (up to 900o Fahrenheit) out of the combustion chamber and through the heat exchanger (Black Arrow). (D) The combustion gases exit the heat exchanger (now cooled to less than 130o) and are forced outdoors through the PVC vent pipe (Gray Arrow). 

## Circulating the Warmth (Blue and Red Arrows) (E) The circulation blower draws in room air (Blue Arrow) via louvers beneath the fireplace... (F) ...and forces it across the heat exchanger fins. This transfers more than 90% of the heat inside the tubes to the room air. (G) The blower forces this warm air out through louvers above the fireplace to warm the home (Red Arrow). 

## Adding the Humidity (H) Droplets of moisture, a by-product of the Mantis’ super-efficient heat exchanger, are captured in a holding tank (not visible). (I) Once the Mantis reaches operating temperature, a pump cycles on to send any collected water onto a stainless steel tray above the combustion chamber, where heat and airflow circulate the water vapor. This added humidity helps alleviate the static shocks, wood furniture damage, and even sore throats caused by dry winter air.

# Quality Construction – Factory Tested Critical internal components in the Mantis – including the heat exchanger – are manufactured from the same corrosion-resistant and heat-resistant stainless steel that was developed for high-efficiency central furnaces.
The steel cabinet is finished in matte black powder coating to resist chipping and smudging. The Mantis Bay Window is available with decorative fireplace frames in contemporary nickel chrome plating, or matte black. Ceramic glass withstands temperatures in excess of 1,500-degrees F and radiates more heat into the room, while providing a great view of the flames and log set. The Mantis’ hand-painted ceramic fiber log set complements the flame pattern, and glows when heated to provide exceptional realism. Two rugged printed circuit boards – designed specifically for the Mantis – monitor all functions and controls. The hand assembled wiring harness is made fromheat-insulated copper wire fitted with clicklock connectors for reliable performance. Two powerful blowers inside the Mantis feature maintenance-free motors driving precisely balanced fans for a lifetime of quiet, efficient performance. One fan draws air into the combustion chamber and draws hot gases through the heat exchanger. The second fan draws room air across the heat exchanger and circulates the heated air throughout the room. To ensure your fireplace performs flawlessly, every Mantis is connected to gas, electricity, and a PVC exhaust system, and test fired before it leaves our factory.

# Humidify While You Heat - Greater Comfort The Mantis captures condensed water – a by-product of its clean combustion and super-efficient heat exchanger – and evaporates it to introduce humidity to the room air. This water contains fewer contaminants than the drinking water in most homes. An automatic blower in the Mantis gently diffuses the humidified air into the room. The result is a more comfortable home environment.

B C

(A) Water vapor, a combustion by-product, condenses out of the rapidly cooled exhaust and collects in a holding tank (not shown). (B) Mantis pumps the water onto an evaporation tray above the firebox. (C) Heat and circulating air evaporate the water to create humidity. Automatic Humidification Most heaters dry the air. Mantis actually adds humidity to the home for greater winter comfort.

# Versatile Installation With the power-vented exhaust and intake made from PVC, the venting options are numerous. Install the Mantis as a direct-vent co-axial system, as a direct-vent co-linear, or as a single-vent system. Any vent configuration may be used with any Mantis package. Using PVC for venting significantly reduces installation time, and requires cutting a much smaller opening in the home’s exterior than is required for conventional metal venting. This makes Mantis ideal for any installation, especially for sunrooms, basements, and other applications that demand unobtrusive venting. Packages include PVC vent adaptors for single and co-linear venting. Lengths of 1 1/2-inch PVC to complete the vent run are available at your local hardware store.
