Lemfema Propane Gas Patio Heater Repair, Replacement Parts Kit
This kit is positioned as a comprehensive propane patio heater repair assembly including a control valve with pilot port, thermocouple sensor and dump (tilt) switch. Thread specs: inlet Female M10×1, outlet 7/16”-24UNF, pilot connection M8×1. The valve operates at low pressure and uses an 8mm spindle shaft.
Features include gold-plated thermocouple connectors and a smooth (unthreaded) thermocouple body that fits mounting holes by notch retention. The listing notes the valve is not suitable for natural gas heaters and recommends thread tape to prevent leaks. Installation guidance suggests minor hole enlargement or epoxy for thermocouple mounting when needed.
TEENGSE Fire Pit Control Safety Valve With Thermocouple
This kit includes a brass safety control valve and one thermocouple intended for outdoor propane patio heaters, standing heaters and some Hampton Bay models. The kit is described as manufactured from heavy-duty brass for durability and long-lasting performance.

The product emphasizes easy installation, recommending vertical installation at the device opening. The scope centers on low-pressure propane systems and flame-failure safety control. The listing frames this as a straightforward replacement for common pilot and valve failures on outdoor heaters and fire pits.
MCAMPAS CSA Certified Gas Safety Control Valve With Igniter
The MCAMPAS unit is a 1/2 PSI brass safety valve featuring an integrated piezo igniter and a thermocouple solenoid. The valve specifies thermocouple thread M8×1 and thermocouple opening and closing current thresholds (≤80mA opening, ≥20mA closing).
Designed as a direct replacement for various Garden Sun heaters, the valve includes an igniter outlet suitable for connecting an electronic igniter wire. The valve’s operating details include an igniter driven by the rotating rod to produce the spark on start-up, making it a combined control and ignition solution.
Brass Safety Valve Main Control Kit Pilot Burner Assembly (BGD)
This kit supplies a main control valve with inlet, outlet and pilot ports plus a pilot burner tube assembly and tilt/FD4 dump switch. The pilot thread is M8×1 and wiring includes multiple leads: ~9.84 inch on the pilot and ~7.87 inch spare lead, with 4.8mm flat terminal connectors.

The product lists compatibility with typical patio heater tilt safety circuits and compression fittings for pilot tubing (4mm olive). The kit is positioned to solve multiple failure points at once, replacing the valve, pilot tubing, ignition terminal and tilt switch in a single install package.
MENSI Outdoor Patio Heater Replacement Gas Control Valve
The MENSI control valve is specified for GARDENSUN brand old heaters and includes a 90° nozzle orifice (2.0mm) intended to fit orifice panel mounts. Constructed from brass and listed as certified, the valve is targeted for heaters that use the specific orifice shape and layout.
This part is a direct-target replacement for legacy GardenSun units rather than a universal valve. The listing emphasizes correct model matching to ensure compatibility with the old heater orifice panel and mounting arrangement.
Buying Guide: How To Choose A Patio Heater Gas Valve
Replacing a patio heater gas valve or safety kit requires attention to mechanical fit, gas type, safety ratings, and ignition compatibility. The sections below outline the core purchase considerations and provide multiple comparison perspectives to help you match parts properly.
Tips for Getting the Best HVAC Prices
- Prioritize Quality Over Cost
The most critical factor in any HVAC project is the quality of the installation. Don’t compromise on contractor expertise just to save money. - Check for Rebates
Always research current rebates and incentives — they can significantly reduce your overall cost. - Compare Multiple Quotes
Request at least three estimates before making your choice. You can click here to get three free quotes from local professionals. These quotes include available rebates and tax credits and automatically exclude unqualified contractors. - Negotiate Smartly
Once you've chosen a contractor, use the proven strategies from our guide — How Homeowners Can Negotiate with HVAC Dealers — to get the best possible final price.
1. Confirm Gas Type And Pressure
- Propane vs Natural Gas: Many replacement valves are specific to propane. Confirm your heater’s fuel type before selecting a part.
- Low-Pressure Operation: Patio heaters typically use low-pressure valves (fractions of PSI). Check listed pressure specs like 1/2 PSI or manufacturer guidance.
2. Thread Sizes And Mechanical Fit
- Inlet/Outlet Threads: Match inlet and outlet thread sizes (e.g., M10×1, 7/16”-24UNF). Mismatched threads require adapters or rework and risk leaks.
- Pilot Connection: Pilot threads commonly appear as M8×1. Confirm pilot tube fittings and compression olive sizes before ordering.
- Thermocouple Mounting: Thermocouple bodies may be threaded or smooth; note whether your heater uses a tapered notch or threaded mount.
3. Safety Features And Certification
- Flame Failure (Thermocouple) Compatibility: Ensure valve kits include or accept thermocouples with the correct opening/closing current ratings listed by the manufacturer.
- Tilt/Dump Switch: A tilt switch or FD4 dump switch is required on many standing heaters; check wiring terminals and switch ratings to match the original safety circuit.
- Certifications: Where applicable, prefer valves with safety certifications (CSA, etc.) for regulated installations.
4. Ignition System Matching
- Integrated Piezo vs External Igniter: Some valves include an integrated piezo igniter; others provide a rectangular terminal to connect an external electronic igniter. Match to your heater’s ignition wiring.
- Wire Terminal Type: Check terminal sizes (e.g., 4.8mm flat) and lead lengths to avoid rewiring or splicing in confined assemblies.
5. Material And Durability
- Brass Construction: Brass is common for valve bodies and pilot fittings for corrosion resistance.
- Gold-Plated Connectors: Some thermocouple connectors are gold-plated for improved conductivity and corrosion resistance; evaluate based on environment (coastal vs inland).
6. Installation Considerations
- Ease Of Replacement: Kits that consolidate valve, pilot tube, thermocouple and tilt switch reduce installation steps and troubleshooting.
- Thread Tape & Sealants: Use proper gas-rated thread tape or sealant as recommended. Avoid over-tightening fittings to prevent damage.
- Mounting Differences: Thermocouples may require enlarging or adapting mount holes (some kits note using epoxy or a slight drill fit for smooth bodies).
7. Compatibility And Model Matching
- Brand-Specific Parts: Certain valves are listed for specific brands (e.g., GARDENSUN, Hampton Bay). Use model compatibility notes when available.
- Universal vs Dedicated Kits: Universal kits can work across models if threads and pressures match, but dedicated replacements avoid fitment uncertainty.
8. Troubleshooting Perspective
- Pilot Lights That Don’t Stay Lit: Likely thermocouple or thermopile failure, or a valve losing its solenoid hold current. Verify thermocouple continuity and valve actuation currents if available.
- No Spark/No Ignition: Check integrated igniter pins and wiring to the valve. Some valves require rotation to engage piezo sparks.
- Intermittent Flame Extinguish: Tilt switch wiring or a weakened thermocouple can cause random shutdowns. Inspect mechanical tilt switch and thermocouple seating.
9. Comparison Considerations
- Comprehensive Kits vs Single Parts: Kits like the Lemfema and BGD replace multiple points of failure in one purchase; ideal when multiple components are aged.
- Integrated Igniter Benefits: Valves with integrated igniters (e.g., MCAMPAS) reduce wiring complexity but must match the heater’s ignition method.
- Brand-Specific Solutions: MENSI targets legacy GARDENSUN heaters; select brand-specific parts for hard-to-fit legacy components.
10. Safety And Professional Service
- Gas Leak Checks: Always pressure-test or bubble-test fittings after installation and before lighting.
- When To Call A Technician: If pressure specs, thread adaptations, certification requirements, or manifold changes are needed, consult a qualified technician. Improper installation can create safety hazards.
