Includes Pan and Burner, Smart Ignition Technology System, and Gas Connections

Smart Ignition Technology System

This system provides the highest level of safety, ensuring peace of mind!

  • The S.I.T. System monitors the presence of a flame, and if this is not detected, automatically makes multiple attempts to re-light. In the event it fails to relight, the system automatically closes the internal gas valve as a safety precaution.
  • Flame sensing technology may be necessary for those who live in an area where such safety features are required by local code!  
  • The American Fireglass S.I.T. system is the smallest electronic ignition system available on the market making it the ideal choice for fire bowls as well as other fire pit features.
  • You can choose whether to wire your fire pit to a wall switch or the fire pit remote control (add-on) to operate the fire pit.

When not in regular use, or to prevent accidental ignition, it is recommended that you turn off the gas supply at the gas shutoff valve. A listed gas shut-off valve is required by the Code to be installed prior to the location of the appliance.


The Pan & Burner

Pans are important components of a fire pit, they not only support the burner but can be easily removed when access is required for maintenance, they also greatly reduce the amount of fire glass you will need for that perfect finish, saving you money.

In the case of LP applications, they also provide a barrier allowing the air mixer to function efficiently. This barrier also reduces the amount of unburnt LP that can pool below the burner, which is not something you want to happen!

Drop-in Trays are designed to sit in an opening of about 1″ bigger than the quoted tray size, resting securely on its generous lip. The tray size relates to the dimensions of the base and excludes the 1 ¼” support rim. The pans themselves are 2″ deep.

  • Pan and the Burner are made of 100% high-grade 304 stainless steel.
  • The gas holes in the burner are drilled, not punched ensuring a smoother flow of gas, a better flame, and preventing whistling noises.
  • Weep holes are drilled in the bottom of the Pan to allow for drainage, preventing water accumulation.

The pan comes with a built-in T-Burner. Linear Burners have a distinctive, long, single curtain of flame and suit long narrow fire pits or fire tables.

Pan Sizes

What to Consider:

  • American Fire Glass S.I.T. Linear Fire Pit Kits are for outdoor, vented, fire features ONLY.
  • The Liquid Propane version is intended for whole house propane supply only
  • Ventilation:
    • Install a minimum of 18 square inches of ventilation at the bottom on at least two opposing walls of the enclosure.
    • Vents provide airflow which avoids overheating the components and allows the air mixer to function properly.
    • Drainage – Sufficient drainage must be included in the design to prevent components from becoming submerged.
    • The S.I.T. valve box requires a minimum of one cubic foot of space beneath the bottom of the tray for installation.
  • Gas Installations
    • Take into consideration your available BTUs at the fire pit site when choosing a tray/burner size. Ensure you have sufficient gas pressure to operate your Fire Pit.
