affect Btu’s.  As a result your Btu’s may vary slightly from

 Clearance to Combustibles (Not to be used in 

an enclosed space)

Description:

  These fi re pits are designed to be installed into a non-combustible enclosure.  They are a “drop-in” style 

system to make installation quick and convenient.  Due to the length of the thermocouple wire the control panel must be 

mounted within 24” of the burnerpan.  The fi re pit uses a thermocouple manual safety ignition (TMSI) system.  This 

system has a battery operated manual Piezo ignition to light the burner, then uses a thermocouple to keep the fi re pit 

burning during operation.  If the fl ame for any reason is blown out or extinguished the thermocouple will cool down and 

shut the gas supply OFF. Media (not supplied) is required inside the burner pan for operation (See page 12).  

WARNING: 

Proper clearances from combustible materials must be maintained from all sides, top and bottom of this 

appliance.  Use the specifi cations listed on pages 4 and 5 for proper clearance to combustibles. 

Firegear Outdoors fi re pits are constructed and tested to follow the rigid ANSI standards for gas appliances and 

manufactured safely providing dependable and certifi ed products.  If these fi re pits are not installed according to the 

installation manual (i.e. not providing ventilation, not providing proper drainage, installing fi re pits below grade or 

modifying the existing products from a normal installation) Firegear Outdoors cannot be responsible if the product does 

not operate as designed.  

Modifying the fi re pit directly out of the carton will void the warranty and nullify the CSA listing it was certifi ed for. Before 

you consider creating your own custom design with a certifi ed product ensure you contact Firegear Outdoors to consult 

the installation before proceeding.   If you move forward and modify a product without consulting, Firegear Outdoors 

cannot be responsible if the product does not operate as designed.
