Test Fire – Custom Linear Gas Fireplace

Wednesday, May 25th, 2011

Acucraft just finished test firing a large custom linear gas fireplace. Prior to shipping all custom gas fireplaces, we burn and test every fireplace. The below fireplace has a huge 120″ wide x 24″ high viewing area. The customer wanted a large 12″ -18″ flame and has propane as the fuel source.

The pictures do not do justice to how awesome the flames look.

Flame Test for Custom Linear Gas Fireplace
Viewing Area is 10′ Wide x 2′ High

Propane Gas and huge flames from a propane fireplace are difficult to achieve. Propane is heavier than air, Natural Gas is lighter than air. Propane needs to be delivered at 3X the pressure of Natural Gas, which requires much more outside air for combustion to be mixed with the Propane Gas. The addition of more outside air turns the flame blue. Acucraft and our customers desire tall slow moving yellow flames.
Therefor we at Acucraft, Custom designed a long 100+” elevated burner with the gas entering the burner in 3 areas, middle and both ends. This will evenly distribute the Propane. The design included 3 large 200,000 BTU valves, with variable flame height control via remote control.

Below is a link to a video of the fireplace in action.

The Customer selected recycled glass as the media, which will be installed at the site to hide the burner and more evenly distribute the flame.

The outside combustion air will be distributed to the firebox in the slotted openings, shown above along the front flange. There is  two panes of glass, this will keep the glass cooler to the touch with air transfering between the glass.

This Fireplace along with another large custom fireplace are being shipped to there new home in Indiana.

The fireplaces just keep getting bigger, below is a photo of a  huge gas fireplace we are testing tomorrow. The dimensions on this fireplace are 11′ wide and 3′ tall = 4,752 square inches of viewing area.

The firebox is completed and the insulated panels are being installed. Tomorrow we burn and test.

Before and After Story

Friday, May 20th, 2011

The Before and After story is one of our favorites at Acucraft. We had a customer with an outdated, very inefficient fireplace and they wanted to heat there entire home and wanted a unique look. The customer selected our Hearthroom 36 Wood Burning Fireplace, BTW at $3,200 this is the best value on the market for a High Tech Wood Burning fireplace. The average market price for this type of fireplace is $4,400.

Ever time the customer used there old fireplace all the air and heat went up the flue and left the house very cold. They were not able to use the fireplace in the winter, just in the fall and spring. With the cost of heating continuing to rise there desire was to heat with wood as a supplement all winter long.

The customer also wanted to cook with the fireplace using our BBQ Grill featured in the after picture below. The Acucraft BBQ Grill is made from Kitchen Grade 304 Stainless Steel and is so much fun to use.

4 Stages of a Fire

Wednesday, May 11th, 2011

In response to many requests from my last post, the purpose of this post is to discuss the 4 different wood burning stages of fire. We at Acucraft have adopted these standards and this post will differ from the chemical breakdown of wood.

These stages are very important to understand when using an efficient wood burning fireplace or stove to maximize the BTU’s per pound of wood. Many people new to efficient fireplaces stay in the creosote stage with wet wood, focus on getting your fire to be in stage 3.

Stage 1 – Start Up Stage
– The start up stage involves warming your fireplace flue and creating draw to begin pulling in the combustion air. We recommend starting with dry kindling and a fire starter, do not use newspaper. Many chimney sweeps will say the majority of creosote build up is caused by newspaper along with a cold flue.

 “Simple Wood Moisture Test” which anyone can do: 
“Add one large piece of wood to the top of an established fire. If it starts to burn on three sides within one minute, it is dry and seasoned and right for burning, If it turns black and starts to burn in about three minutes or more, it is damp. If it turns black and does not start burning until five minutes or more, it is green and wet. If it hisses at any time, the wood is soaked and will not burn until the excess moisture is boiled away.”

Stage 2 – Creosote Stage
– Always start with dry seasoned wood, preferably under 20% moisture content. Add the dry split wood above the burning kindling fire. Always ensure there is proper flow for the smoke and heat to exit up the flue. The goal is to get out of this stage, the wood temperature will rise as it begins to burn. The moisture will be evaporating from the wood as it reaches 212 F and all the moisture will be out of the wood between 400 and 414 F. During this stage the wood will be hissing and bubbling on the ends. Keep the damper and combustion controls wide open during this stage, until you see the wood cleanly burning with out grey smoke etc..

Stage 3 – Heating Stage
– Once the wood has burned out the moisture and you have the combustion control dialed in, the flames will take on a slow moving orange flame. Maintain this type of burn for maximum heat and minimal creosote build up on your glass and flue. This stage can be maintained for 6-10 hours between loads of new wood, depending on your wood and your fireplace.

“Simple Wood Moisture Test” which anyone can do: 
“Add one large piece of wood to the top of an established fire. If it starts to burn on three sides within one minute, it is dry and seasoned and right for burning, If it turns black and starts to burn in about three minutes or more, it is damp. If it turns black and does not start burning until five minutes or more, it is green and wet. If it hisses at any time, the wood is soaked and will not burn until the excess moisture is boiled away.” 

Stage 4 – Die Down
– If you are going to let your fire go out in your fireplace, open the damper. During this stage, your flue will be getting colder at the top and when the cold meets with slow moving smoke creosote can occur. By opening your damper during this stage you are able to keep the flue warmer until the fire goes out.
