Montigo Exemplar R520 See-Through Natural Gas Fireplace R520STN

Montigo R520STN is an Exemplar see-through linear gas fireplace for an indoor installation. This natural gas version is rated at 80,000 BTU/hr in the exact-model manufacturer catalog. Its power-vent installation must be designed as a complete system, with an approved power vent and the appropriate connecting cord ordered for the selected route.

Exact model and package

Required components

The manufacturer’s ordering instructions require the fireplace, a compatible power vent and a power-vent cord. These are distinct from optional decorative media or a remote. Use only a vent system approved for this model and its gas/control revision. The catalog lists 5/10-inch wall, roof and flush-louvered power-vent choices. The selected route must comply with the appliance and power-vent manuals; maximum runs, offsets and termination clearances are not interchangeable between systems.

Provide the correct gas supply, accessible service shutoff, electrical/control connections, compliant framing and all required protective parts. Install the supplied media according to the burner instructions. A larger decorative-media order must not be assumed necessary merely because the appliance needs media to operate.

Optional configuration

The RXM40VAC on/off remote is listed as optional for the cataloged system. The IOSK5 indoor/outdoor seal kit is the model-specific optional conversion package listed for R520ST; an indoor/outdoor installation requires the approved kit and its own instructions rather than simply placing the indoor unit in an exterior wall. Verify the selected accessory and installation arrangement against the unit’s supplied documentation.

Installation planning

Use exact-model drawings for the enclosure and finished opening. The model number is not a framing dimension. The manufacturer provides separate specifications for single-sided and see-through units, with additional requirements for vent orientation, control-box service access and the power-vent connection. A qualified installer must verify the appliance’s rating plate and complete model/control revision before selecting components.

Installation and service must follow the Montigo documentation and applicable codes. Keep glass and protective barriers correctly installed, maintain all specified clearances and arrange regular qualified inspection. Consult the manual warranty appendix for component coverage and installation/service conditions.
