RH Peterson G8E Unvented Gas Log Set Manual

Introduction

The RH Peterson G8E Unvented Gas Log Set is a vent-free gas fireplace system designed to provide supplemental heat and realistic fire presentation without requiring a traditional chimney or open flue. The system combines a compatible G8E burner assembly with an approved Real Fyre log set, creating an installation option for properly sized, approved fireplaces and fireboxes.

Because unvented appliances release combustion products into the living space, the G8E must be installed and operated exactly as specified by the manufacturer and applicable local codes. The appliance includes an oxygen-depletion safety system that is designed to shut off the gas supply if oxygen levels become unsafe. This safety feature does not replace professional installation, proper room ventilation, carbon-monoxide protection, or routine inspection.

This gas log set is intended for homeowners, remodelers, and heating professionals seeking a supplemental indoor heating solution with fewer structural requirements than a vented fireplace. It can be suitable for approved masonry fireplaces or listed fireboxes when the burner, logs, controls, gas supply, and installation clearances are correctly matched. It is not a universal replacement for every fireplace or gas-log burner.

Use only the log arrangement and components approved for the G8E system. Mixing burners, logs, valves, pilot assemblies, or accessories from other manufacturers can create unsafe combustion, poor flame performance, or loss of warranty coverage.

Installation location: Only an approved indoor fireplace or listed firebox that meets the manufacturer’s dimensions and clearance requirements.
Gas piping: The supply line must be sized for the appliance’s maximum input and required inlet pressure.
Performance: Flame appearance and heat output depend on fuel type, gas pressure, burner adjustment, room size, and log placement.

How to Install and Set Up the G8E Gas Log System

Installation should be performed by a qualified professional familiar with unvented gas appliances. Before beginning, confirm the burner model, fuel type, firebox approval, minimum dimensions, clearances, and local code requirements.

Turn off the gas supply and allow the fireplace to cool completely. Remove combustible materials and confirm that the firebox is clean and suitable for an unvented appliance.
Verify that the G8E burner and log set are compatible. Do not substitute a different burner or place unapproved logs on the burner.
Install the gas connection using approved fittings and leak-detection procedures. Never test for leaks with an open flame.
Check inlet gas pressure with the appliance operating at the required flow. Insufficient pressure can prevent correct pilot and burner operation.
Position the burner according to the installation manual, then place each log on its specified support. Bottom logs must sit fully and securely on the burner.
Install batteries or connect the approved control system if included. Pairing procedures vary by control model; follow the instructions supplied with that control.
Light the pilot according to the valve instructions. Hold the control as directed until the safety pilot remains lit, then ignite the main burner.
Observe the flame. Shut the system down immediately if flames contact the firebox, logs are unstable, soot appears, or the pilot repeatedly goes out.

Keep the area around the appliance clear, install carbon-monoxide alarms as required, and never operate the log set with doors, screens, or accessories configured contrary to the appliance instructions.

G8E Troubleshooting Guide

Pilot Will Not Light

Confirm that the gas supply is on, the shutoff valve is open, and the control is in the correct pilot position. Purge air from a new gas line only through the approved lighting procedure. If the pilot still will not light, stop and have the gas supply, igniter, thermocouple, and pilot assembly inspected by a qualified technician.

Pilot Lights but Goes Out

Hold the control for the specified time and ensure the pilot flame fully contacts the safety sensor. Low gas pressure, a blocked pilot, a damaged thermocouple, or an improperly positioned component can cause shutdown. Do not bypass the oxygen-depletion safety system.

Main Burner Does Not Ignite

Check that the control is calling for heat and that the pilot remains stable. Inspect the control batteries where applicable. If the valve clicks but the burner does not ignite, turn the system off and arrange professional service rather than repeatedly attempting ignition.

Yellow Flame, Soot, or Odor

Turn off the appliance immediately if soot, unusual odor, or abnormal flame behavior occurs. Incorrect log placement, restricted air openings, contaminated ports, improper pressure, or an incompatible log set may be responsible. Never operate the appliance until the cause is corrected.

Support and Warranty

Keep the model information, serial details, proof of purchase, installation record, and service documentation. Warranty coverage can vary by component and may exclude misuse, improper installation, or non-approved parts. For technical assistance, contact RH Peterson Technical Support at 1-626-369-5085 during the manufacturer’s published business hours.

Pros and Cons of the RH Peterson G8E Unvented Gas Log Set

Advantages

No traditional chimney required: A suitable unvented firebox can simplify installation compared with a conventional vented fireplace.
Supplemental heat: The system is designed to deliver heat directly into the room rather than sending most combustion heat outdoors.
Realistic appearance: Compatible Real Fyre logs and an adjustable flame can create a traditional fireplace presentation.
Safety monitoring: The oxygen-depletion safety pilot is an important protection typical of certified vent-free systems.
Configuration flexibility: Fuel type and control options may be available in different factory-approved configurations.

Limitations

Strict installation requirements: It must match the approved firebox, clearances, fuel type, log arrangement, and local regulations.
Indoor air considerations: Combustion occurs in the room, so ventilation, carbon-monoxide alarms, and operating instructions are especially important.
Not a universal log replacement: Logs from another burner system should not be used with the G8E.
Professional service may be necessary: Gas pressure, pilot performance, and abnormal flames require qualified diagnosis.
Best suited for: Homeowners wanting supplemental heat and a realistic fire in an approved installation.
Consider another solution if: A homeowner requires a primary heating system, cannot meet vent-free appliance regulations, or prefers combustion products to be exhausted outdoors.

Faqs

How do I set up the rh-peterson G8E Unvented Gas Log Set for the first time?

Have a qualified gas professional install the rh-peterson G8E Unvented Gas Log Set in an approved standard wood-burning fireplace. Confirm the appliance is configured for the correct fuel type, the gas supply is shut off, and the fireplace meets clearance and ventilation requirements. Install only the matching G8E burner, connector components, and approved logs. Before lighting, check every gas connection for leaks using an approved leak-detection solution, never an open flame.

Can I install any decorative logs on an rh-peterson G8E Unvented Gas Log Set?

No. Use only the Peterson Real Fyre log set specifically approved for the G8E burner. The underside of the bottom logs includes cutouts and notches that align with the burner and safety components. Incorrect logs or placement can obstruct the oxygen-depletion sensor, alter the flame pattern, cause soot, or create unsafe combustion. Follow the exact log-placement guide supplied with your model, and make sure every log rests firmly and flat before operation.

What should I do if the rh-peterson G8E Unvented Gas Log Set will not light?

First, confirm that the fireplace gas shutoff valve is open and that the control knob is in the correct lighting position. Follow the lighting instructions for your exact ignition system, holding the control as directed so air can purge from a new gas line. If there is no spark, check the igniter position and battery, if applicable. If the pilot will not remain lit, stop trying, close the gas supply, and contact a qualified technician.

Why does my rh-peterson G8E Unvented Gas Log Set produce soot or yellow flames?

Small yellow accents can occur with gas logs, but heavy soot, black deposits, or flames striking the logs indicate a problem. Turn the appliance off and allow it to cool completely. Verify that the logs are positioned exactly as shown in the manual and that burner ports are not covered by logs, embers, dust, or debris. Do not modify the burner or enlarge ports. Persistent soot or abnormal flames require inspection by a qualified gas technician.

What fireplace and gas supply requirements apply to the rh-peterson G8E Unvented Gas Log Set?

The rh-peterson G8E Unvented Gas Log Set is designed for installation in an approved standard wood-burning fireplace, not an improvised enclosure. The fireplace must provide the required clearances, dimensions, and combustion ventilation specified for the exact set. The gas piping must deliver adequate pressure and flow at maximum input, and the burner must match the fuel type. Verify all measurements and local code requirements before purchasing or scheduling installation.

How can I improve flame appearance on the rh-peterson G8E Unvented Gas Log Set?

Begin with correct log placement rather than changing burner settings. The logs must sit fully on their locating points, with no log covering burner ports or safety components. Keep decorative media limited to the materials approved for the G8E system and distribute them only as instructed. Operate the set with the fireplace damper in the required position and avoid drafts from fans or open windows. If the flame remains uneven, have the burner and gas pressure professionally checked.

How often should I clean and inspect the rh-peterson G8E Unvented Gas Log Set?

Inspect the rh-peterson G8E Unvented Gas Log Set before each heating season and periodically during regular use. With the gas off and the appliance cool, remove loose dust from accessible burner and log surfaces using a soft brush or vacuum designed for delicate components. Check that logs remain stable, burner ports are unobstructed, and no soot is accumulating. Arrange professional servicing whenever the pilot changes, flames become abnormal, or odor and performance problems appear.

What should I do if the rh-peterson G8E Unvented Gas Log Set shuts off while running?

Turn the control to the off position and allow the appliance to cool before troubleshooting. Confirm that the pilot area and oxygen-depletion safety sensor are not blocked by a misplaced log, dust, or debris. Check that the room has the ventilation required by the installation instructions and that drafts are not disrupting the pilot. Do not bypass or disable the safety system. If shutdowns continue, close the gas supply and have a qualified technician inspect the appliance.
