Natural gas or propane

Every gas insert leaves the factory set for one fuel, and the rating plate names it along with the pressures the valve expects. Switching fuels is done only with the maker's own conversion kit, not by drilling or swapping parts on site. Pressures at the valve are read against that plate once gas arrives.

The fuel at the house is confirmed before a model is chosen, and the propane supplier or gas company is in the plan from day one. Propane at a house in St. Nicholas and wondering about an insert? Ask a gas insert specialist at (904) 920-5495.

St. Nicholas lies inland. Within Jacksonville city limits, St. Nicholas is its own named neighborhood.

How our gas insert pros install an insert in St. Nicholas

Hookups and first light
The gas and electrical hookups are made, then we light and test the insert with you.

Heavy rain and the termination in St. Nicholas

Well inland, the June to November storms still bring heavy rain. A termination fitted as its instructions show keeps that water out of the liners.

We check it after installation and at each service.

Cleaning a chimney that burned wood

Before a gas appliance connects, section 503.5.6 of the state fuel gas code has the chimney passage checked to be clear and cleaned if it once vented solid or liquid fuel. A fireplace that burned wood falls squarely under that rule.

So every gas insert installation in an old wood fireplace starts with cleaning and a look at the flue. What we find, a cracked flue lining, loose debris or missing parging above the throat, is written down before the liners go in and hide it. The findings are priced separately from the insert.

One gas, set at the factory

Natural gas or propane is decided at the factory, and the rating plate says which. The orifices, pressures and sometimes the valve differ between the two, and a unit is converted only with its maker's conversion kit.

We confirm the gas at the house and the gas on the plate before the insert is delivered. Where a conversion is needed, the kit is ordered with the insert and fitted as its instructions say, with the conversion label applied. Running an insert on the wrong gas is not something to adjust around; it is corrected before first light.

Resealing after service

The intake and exhaust of a direct-vent insert form a sealed path from outdoors to the firebox and back. One maker warns that the vent-air intake system has to be properly reinstalled and resealed after any servicing.

When an insert is pulled forward for service, the liner connections at its adapter are the joints most at risk. We reconnect them as the instructions show, check each joint and run the insert with the glass latched before leaving. A service call that leaves a liner loose behind the surround is worse than no call at all.

Before you switch to gas

Can my fireplace in St. Nicholas take a gas insert?

It depends on the opening size, the flue and the mantel above it, measured against the insert's rating plate. We check all three on a free inspection before you choose a model.

Is the gas insert inspection free?

Yes. Measuring the opening, flue and mantel and writing the estimate are free, and the price you see is the price you pay. The installation comes 10% off when you book it in the three days after that visit.
