Vented Gas Log Set Option

G52 Radiant Burner

Vented Log Set is the most realistic option and is considered decorative appliance (not a heater).  Most of the heat escapes out the chimney – much like a wood fire.  Vented log sets normally have a large BTU input which requires large amounts of combustion air.  The combustion air is pulled from the room that the log set is in, and with the heat from the fire, exhausts that combustion air up the chimney.  This can result in heat loss due to natural draft.  However, they are, like a real fire, cozy to sit next to and warming to any room.

Contemporary Collection Vented Burner is a decorative appliance (not a heater).  It has the same properties as a vented log set.  With various fireplace media like gems and glass - it is a very modern look.

Direct Vent Gas Fireplace Option

Regency Liberty Direct Vent Insert

Direct Vent Insert or Direct Vent Built In is an efficient option for heating.  Direct vent by definition is a unit the draws all combustion air from the outside and returns all of the combustion byproducts to the outside.  What this means is that the direct vent inserts do not "communicate" with the room air at all.  They have a closed combustion chamber with a ceramic glass viewing window.  For direct vent inserts - combustion air and exhaust is relayed through 2 pipes that run up the chimney and are connected to a special cap that separate them.  Most of the direct vent inserts being produced today are listed as heaters.  Many of them come standard with blowers and remote controls.   If your chimney requires new liner, a direct vent insert would be the best option since these unit have liners that are installed with the unit so you not need to have a separate liner installedA Direct Vent built in will have its own venting that needs to be installed based on the space and manufacturer specifications.

Outdoor Fire Tables

Outdoor Fire features such as fire tables, add a little something special to your backyard living space.  They can be fueled by natural gas (hard-piped into your home's gas supply) or use a portable propane tank which allows flexibility.

Ventless Gas Fireplace Option

Unvented Gas Logs

The VentLess Option purpose is heat and they make great heaters.  But ventless burners are not really vent free.  They simply lack the vent to carry products of combustion to the outside.  Therefore, all of those products vent into the home.  In perfect combustion, those products are simply water vapor and carbon dioxide.  Water vapor can contribute to mold and mildew in a home.  Unfortunately, this is the least of the concerns with ventless fireplaces.  Most of the ventless fireplaces do not achieve perfect combustion.  Incomplete combustion byproducts include soot (a known carcinogen) and carbon monoxide.  Combustion air is provided by the room that the fireplace is in.  This means that burning your ventless fireplace consumes the oxygen in the room and replaces it with the products of combustion.  People with asthma, allergies or respiratory issues should speak to their health practitioner regarding a ventless gas fireplace BEFORE purchasing. Proponents of ventless fireplaces say to crack a window during operation.  This is counterproductive for a heater.

Wammoth Services Timeline

Step One

Schedule an In-home estimate appointment to assess gas line installation (for wood to gas fire place conversions) and gas fireplace selection.  An interior chimney scan will be performed during this appointment as most counties require a vent/chimney certification with the gas permit.  Any areas of concern with the chimney will be addressed with the homeowner.  In addition, a gas load will also be performed on the home to determine if the current gas meter provides adequate gas supply when adding a new gas appliance.  There is a $200 charge for the in-home estimate and/or Chimscan appointment.

Step 2

Complete necessary items, if required, prior to moving forward with our estimate: chimney repairs, upgrade current gas meter and any other requirements that are provided at the time of the in-home estimate appointment.  Once the estimate is accepted, the contract and deposit invoice will be electronically delivered.  Order placement and scheduling will occur once signed contract and deposit is completed and received.

Step 3

A tentative schedule is normally one (1) day for gas line installation and one (1) day for the gas fireplace installation.  Some projects may take longer than others.  Back-up dates will be scheduled in case of rain/snow delays and other delays that may occur (Murphy's Law). Please be aware that during peak season (October - February), there may be longer than normal lead times on product, inclement weather delays and schedule delays as the schedule may be booked 6-8 weeks in advance.

Selecting the right company for your project

A new gas fireplace is a considerable financial investment.  Projects vary in price - anywhere between $2,500 - $10,000+.  We strongly recommend you research and vet any professional that is hired for their project.   A legitimate company should have no issue providing the following documentation/information upon request:

  • Certificate of Insurance (Liability)
  • Workman’s Comp Insurance
  • County Business License
  • State Contractor’s License Number

Check the company’s reviews on various online resources and ask the company for testimonials from previous/existing customers.  Also, obtain estimates from different companies.   Not only is this a financial investment, you are putting fire in your home.  Cutting corners to save a few dollars can be catastrophic.

Some things to consider:

  • New or replacement gas appliances require a permit through your county/city.
  • It is recommended that the contractor apply for the permit. If you are asked to pull any required permits for your project as the homeowner – you should question your contractor why they are not pulling the permit.  If your contractor is qualified and licensed – there is no reason why they cannot obtain the necessary permits.
  • Most counties/cities require a vent/chimney certification (based on a chimney inspection performed by a licensed professional) when pulling the required gas permit for a new or replacement gas fireplace.
  • Ensure your contractor is licensed and has the appropriate qualifications to obtain the necessary permits. Visit to verify the license status of the contractor.
  • Ask if the contractor will be performing the work themselves or if they sub-contract the work to another company. If they are subcontracting the work – ask for the subcontractor’s information.
  • Most gas fireplace manufacturers recommend installation by a certified technician through the National Fireplace Institute. You can verify if your technician is certified by visiting

Important Information

When adding a new gas appliance to your home – ensure your current gas meter can provide enough gas supply for all your gas appliances.  A qualified professional will complete a gas load to determine you have enough gas supply to add a new gas appliance.  In some cases, you will need to contact your local gas utility to upgrade your gas meter to allow for additional gas appliances.

Pay attention to clearance to combustibles.  Surrounds and mantel must meet NFPA (National Fire Protection Association) guidelines or residential building code.  Failure to follow these codes/guidelines can result in a fire hazard.

Verify the technician who is installing your gas fireplace is qualified to install your new gas fireplace.  Ask them to provide you with their qualifications before the installation.

Online purchase of gas fireplaces may seem cost effective.  Most qualified professionals are not likely to install a fireplace that was purchased online.

Installing a gas line for “future use” is not advisable.  You may think a contractor is providing you an additional benefit by providing a gas line that may be used for a future gas appliance. Remember – in order for a new gas line to be approved by the county – it must be connected to the gas appliance and the gas appliance is operating as intended.

Your county or city can answer your questions when you need a permit.
