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.
