Gas Fireplace
Inside a gas fireplace installation in Alderene Park
B-vent gas fireplace installation rules
A B-vent fireplace relies on natural draft, so its vent has firm rules. One maker's B-vent manual requires the draft hood to be in the same atmospheric pressure zone as the combustion air inlet, at least 8 feet of vertical rise measured between the unit's top and the termination's top, no more than two 90 degree elbows and a rise of at least 1/4 inch per foot on any horizontal run.
The fuel gas code adds that a Type B vent terminates at least 5 feet above the highest connected draft hood (503.6.6). Our pros check that your Alderene Park home can give a B-vent unit the vertical run it needs before recommending one.
Horizontal vent caps on an outside wall
A direct-vent cap on an outside wall has to stay clear of openings people breathe through. Florida's fuel gas code, in Table 503.8, sets it at least 12 inches above the ground, a porch or a deck, and away from any window or door that opens by 9 inches for units over 10,000 up to 50,000 Btu/h, or 12 inches for units over 50,000 up to 150,000.
The manual for a given model can ask for more, and when it does, the larger number wins. Our installers measure the cap position on your Alderene Park home against both before the hole is cut.
Leak checking every gas connection on the new fireplace
Fittings can loosen in shipping and handling, one maker's manual warns, so every connection is checked once the gas is on. The manual specifies a non-corrosive leak check solution bought for the purpose, never an open flame, and asks for it to be rinsed off after testing.
Our crew checks the connections at the valve, the flexible connector and the shutoff before the first light in your Alderene Park home, and again after the burner has run. The result of the check is noted on your written record, along with the connections tested.
Why a new gas fireplace needs more than your nose
Natural gas and propane are both odorless, and the smell you know is an agent added to them. One maker's manual warns that this added odor can fade, so gas may be present even when you cannot smell it.
That is one reason we leak test every connection with solution instead of trusting smell, and one reason a working carbon monoxide alarm belongs in any home with a gas fireplace. We point out the nearest alarm locations during the walkthrough in your Alderene Park home. If you do not have one near the fireplace yet, adding one before the first burn is a simple step.
