    FAQs

    What type of fuel does the NS-PSH48BR3 patio heater use?

    The heater runs on liquid propane (LP) gas, which is normally provided by a standard 20-pound propane tank (not included).

    What is the maximum heat output?

    This type is perfect for outside places like patios, decks, or backyard seating areas because it can provide up to 48,000 BTUs of heat.

    How large an area can it heat?

    Depending on wind, temperature, and location, the heater may heat up to 200–250 square feet.

    Is this patio heater safe for indoor use?

    No. Only well-ventilated outdoor spaces are suitable for using this heater. There is a significant carbon monoxide risk when using it indoors or in enclosed areas.

    How long will a full propane tank last?

    On high heat, a common 20-pound propane tank will last 8 to 10 hours. Depending on usage and environmental factors, the runtime will change.

    How do I move the heater?

    Wheels are integrated into the base of several variants. Before travelling, always disconnect the tank, cut off the gas supply, and let the unit cool.

    Can this heater be used during windy conditions?

    Although it is resistant to wind, flame stability may be impacted by powerful gusts. If the wind speed is more than 10 to 15 mph, place the heater in a protected outdoor location.

    Do I need tools for assembly?

    Typically, you’ll need basic equipment like an adjustable wrench and a Philips screwdriver. It usually takes one person 30 to 60 minutes to assemble.
