Abstract:
1. An indoor-outdoor gas infrared heater having one or more heat level settings, comprising: a chassis having a burner compartment housing a burner in a burner housing, the burner having ceramic plaques with a plurality of perforations having a total pore area of 0.1-0.2 square inches per square inch of plaque surface area and raised surfaces between the perforations, the raised surfaces tapering into an apex, the burner housing having one lateral end open to allow a burner inlet tube to protrude and plaques having insulation placed around the side peripheral edges of each plaque laid planarly side by side on top of the burner housing, the burner housing attached only to a heat shield end of the chassis and the burner inlet tube of the burner housing located opposite the heat shield end left unattached but supported by a seat bracket having a central opening allowing movement of the burner inlet tube therethrough to allow the burner housing to contract and expand during the process of heating and cooling of the plaques; an operating system compartment separated from the burner compartment housing an operating system including a control module electrically connected to a control valve having a main valve connector to the burner and a connector to a pilot assembly, a power source and an activator for triggering the heater, the control valve operating at a low voltage having multiple pathways with each pathway including an orifice having a diameter rated according to a heat input on the heater, the orifices controlling the amount supplied and designating the type of gas flowing into the burner at a flow rate for a designated heat level setting, the control valve including a converter stem to ensure delivery of a correct manifold pressure by the control valve for the type of gas used; and, a compartment divider further dividing the operating system compartment to result in a third burner venturi compartment comprising a flue kicker placed underneath the inlet tube of the burner having one end attached beneath a seat bracket holding the inlet tube of the burner and another end attached to the compartment divider, the compartment divider shielding the control module, control valve, power source and activator on the operating system compartment from heat coming from the burner inlet tube of the burner housing protruding from the burner compartment when the burner is turned “off” just after usage.
