Monessen Natural Blaze 27 See-Through Gas Log Set

The manufacturer markets this 27-inch log-and-burner system with the Natural Blaze burner as standard. The burner and mandatory NBST27-F decorative logs are separately packaged; the quote must identify both components.

Two-sided log design; standing-pilot millivolt control with pilot ignition and flame adjustment. Burner package includes grates, on/off switch and harness, anchoring hardware, flexible-line fittings and the specified lava-rock and rock-wool materials.

Specify factory natural-gas NBST27NV-C or propane NBST27PV-C and the required NBST27-F log package. No IPI model is listed for this current see-through burner.

A compatible see-through fireplace or listed vent-free enclosure, correct gas supply, adequate room air, all required clearances and qualified installation are separate project requirements.

For an approved vented installation, provide the manual's permanent damper opening and damper clamp; thermostatic operation is not permitted.

Optional millivolt controls: RCB battery remote, TSST touchscreen thermostat, TS temperature sensor and RRCM insulated receiver cover. Thermostatic use is limited to approved vent-free installations.

Optional variable-flame kits: HILOKTN for natural gas or HILOKTP for propane. VR1000A volcanic rock and the 28–48 inch adjustable flat-black CABL hood are listed accessories. A hood may become required by the selected mantel-clearance arrangement.

This is supplemental room heat, not a primary heating system. Vent-free operation consumes room air; installation requires a room-air assessment and compliance with the rules for the project location.

Do not install in a bedroom or bathroom. Operate any fireplace glass doors fully open. Maintain required separation from curtains, furniture and other combustibles; the full installation manual controls over abbreviated website dimensions.

Factory gas type must match the rating plate. The installer must verify supply/manifold pressures, pilot performance and the prescribed media or log positions.

Minimum opening is 32 W × 19 D × 21.5 H inches. A front barrier up to 3 inches raises required depth to 24 inches; barriers above 3 inches are not recommended.

Manufacturer imagery may show a different size, separate fireplace enclosure, liner, trim or optional controls. These surroundings are not included with the burner or log package.

Installation, gas piping, materials, venting where applicable, finishing, delivery, optional accessories and tax are separate.
