Square Fire Pit Kit | Drop In Pan | S.I.T. Electronic Ignition

If you are building an outdoor gas fire pit, be it with Propane or Natural Gas, this American Fire Glass Smart Ignition Technology (S.I.T.) Fire Pit Kit will not only help you to produce a professionally looking fire pit but also one with family-friendly fire pit safety features and allow you to enjoy all the benefits of a fire pit at the flick of a switch or press of a button!

Smart Ignition Technology System

This S.I.T.  electronic ignition fire pit system provides the highest level of safety for your fire feature. It constantly monitors for the presence of a flame, if this is not detected, the system automatically makes multiple attempts to re-light the burner. If unable to do so system then automatically closes the internal gas valve as a safety precaution. This is ideal for those who live in an area where such safety features are required by local code or simply want the highest level of protection for their family and friends!


Square Fire Pit Kit | Drop In Pan | S.I.T. Electronic Ignition
Includes Pan, Smart Ignition Technology System, and Gas Connections


The S.I.T. system is the smallest electronic ignition system available on the market making it the ideal choice for fire bowls or fire pit features.

The system can either be wired to a wall switch or if you like the idea of a remote controlled fire pit, there is an S.I.T. remote control (add-on, not included) available.

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 Gas Fire Pit Burner & Pan

Both the Pan and the Burner are made of 100% high-grade 304 stainless steel and are built to endure the rigors of the outdoor environment. 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!

The Square Drop-in Tray is 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. Weep holes are drilled in the bottom of the Pan to allow for drainage.

The gas holes in the burner are drilled, not punched. This ensures a smoother flow of gas, and a better flame, and prevents whistling noises. Weep holes are drilled in the bottom of the Pan to allow for drainage, preventing water accumulation.

There are 5 tray sizes: 12, 18, 24, 30, and 36 inches square. The tray comes with the appropriate burner and as you can see from the table below, the burner sizes vary with the pan size and capacity. Please note that the 24″, 30″, and 36″ standard kits are supplied with an 18″ burner, only the high-capacity kits come with larger diameter burners. If you are considering a high-capacity kit please ensure that you have sufficient gas pressure to cope with the BTUs of the burner or it will be impossible to achieve a reasonable flame height. In order to avoid disappointment we suggest that a gas technician confirms this, after all, Fire Pits are all about the flames!

Square Fire Pit Kit | Drop In Pan | S.I.T. Electronic Ignition – What to Consider:

  • American Fire Glass S.I.T. Square Fire Pit Kits are for outdoor, vented, fire features ONLY. 
  • 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. For more information on this please read our post – How to successfully build a gas fire pit 
  • 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. Not only does this provide airflow to avoid overheating the components and air for the air mixer to function properly, but it is also essential in the event of gas leaks and especially in the use of LP applications where unburnt LP can pool below the burner due to being heavier than air!
  • The S.I.T. valve box requires a minimum of one cubic foot of space beneath the bottom of the tray for installation.
  • Drainage – Sufficient drainage must be included in the design to prevent components from becoming submerged.
  • Installation – Certified NFI Professional Recommended
