Reliance Liquid Propane Gas Control Valve 100112330

Check Price on Amazon

This valve is listed as a replacement for specific water heaters and is manufactured by Resideo/Honeywell for Reliance and A.O. Smith branded units. The product page emphasizes the need to provide model and serial numbers to confirm fitment, which is important because water heater gas valves are model-specific.

• Compatibility Note: Designed for liquid propane water heater installations where the original valve matches the 100112330 part number.
• Application: Primary use is water heater thermostat control and gas shutoff rather than low-pressure outdoor heaters.
• Safety Consideration: Always verify serial/model numbers and consider professional installation for water heater gas valve replacement.

Stanbroil Low Pressure Propane Flame Failure Control Valve Kit

This kit targets low-pressure propane systems for fire pits, grills, and heaters. It includes a control valve, a 600mm thermocouple, and a Bakelite knob for manual adjustment. The kit’s maximum working pressure is listed at 1/2 PSI (65 mbar) and the main valve uses 3/8″ male flare threads.

• Materials: Brass valve body for corrosion resistance and durability.
• Max Rating: Up to 50,000 BTU rating on compatible systems as stated by manufacturer specifications.
• Intended Use: Replacement parts for low-pressure appliances with flare connections and thermocouple-based safety.

WADEO Low Pressure LPG Propane Gas Valve Kit

Check Price on Amazon

The WADEO kit is positioned for low-pressure propane systems such as grills, fire pits, fireplaces, and patio heaters. It lists a 3/8″ flare inlet/outlet and a 600mm thermocouple length, making it comparable to other low-pressure kits for outdoor heating appliances.

• Construction: Brass components for strength and longevity in outdoor conditions.
• Compatibility: Suited for low-pressure LPG systems; verify thread sizes and thermocouple type before replacement.
• Installation Tip: Use approved thread sealant or tape rated for gas connections and test for leaks after installation.

Lemfema Propane Patio Heater Control Valve & Thermocouple Kit

Check Price on Amazon

The Lemfema kit focuses on patio heaters and outdoor propane heaters with a thermoelectric safety system. The product highlights thread measurements such as inlet female M10*1 and outlet 7/16”-24UNF, plus an 8mm spindle shaft. The manufacturer states compatibility with many outdoor propane patio heaters but notes it is not suitable for natural gas models.

• Key Measurements: Inlet/outlet thread sizes and spindle shaft details are critical to ensure mechanical fit.
• Thermocouple Design: Gold-plated thermocouple connector for improved conductivity, and some mounting customization may be required.
• Use Advice: The product description suggests thread tape and occasional minor modification of mounting holes for fitment; assess fit carefully before permanent installation.

MCAMPAS CSA Gas Safety Valve With Piezo Push Ignition

Check Price on Amazon

The MCAMPAS valve is a low-pressure brass safety valve designed for patio heaters and includes an integrated piezo igniter. It is CSA referenced for safety expectations and includes a thermocouple solenoid valve with specified opening and closing current ranges. The thermocouple thread is M8x1, and the valve is rated for 1/2 PSI systems.

• Integrated Ignition: Built-in igniter port for electronic igniter connection or piezo operation.
• Electrical Specs: Thermocouple solenoid opening current ≤80mA and closing current ≥20mA; important when matching thermocouple output.
• Application: Replacement for garden sun-style propane heater control valves where integrated ignition and safety solenoid are required.

Buying Guide: Choosing The Right Propane Heater Control Valve

Selecting a suitable control valve requires matching the valve to the appliance and operating conditions. Consider the following factors to narrow choices and ensure safe operation.

1. Confirm Appliance Type And Pressure Rating

Different valves are designed for low-pressure outdoor appliances (typically up to 1/2 PSI) versus medium/high-pressure systems in certain appliances. Patio heaters, fire pits, and grills commonly use low-pressure valves. Water heaters and some indoor appliances require model-specific valves rated for their system. Always match pressure specifications.

2. Thread And Connection Types

Measure or check the original valve for thread size and type: common fittings include 3/8″ male flare, M8, M10, 7/16”-24 UNF, and various NPT sizes. Flare vs. NPT vs. metric threads are not interchangeable without adapters; selecting the correct thread prevents leaks and mechanical issues.

3. Thermocouple Compatibility And Electrical Specs

Valves with thermocouple solenoids require the thermocouple to produce sufficient current. Check the valve’s required opening and holding currents and confirm the replacement thermocouple’s output is compatible. Manufacturers may list the thermocouple thread and length—match these closely.

4. Integrated Ignition Features

If you need a valve with piezo or electronic ignition, ensure the valve provides the appropriate port and mechanical action. Integrated igniters simplify installation but must align with the appliance’s wiring and sparking mechanism.

5. Material And Environmental Durability

Outdoors, brass valves resist corrosion and perform well under temperature variations. For water heaters and indoor use, materials must meet appliance manufacturer specifications. Look for quality brass or OEM manufacturer designations for longevity.

6. Safety Certifications And Manufacturer Fitment

Where available, prioritize valves with safety certifications (CSA, UL references) and those manufactured or specified by OEMs. For water heaters, rely on OEM part numbers and confirm with model/serial numbers to ensure proper thermostat and safety integration.

7. Thermocouple Length And Mounting Style

Thermocouple length affects mounting and routing. Kits often include a specified length (e.g., 600mm). Consider whether the thermocouple mounts with threaded bodies or friction-fit tips; some kits require minor mounting modifications.

8. Flow Capacity And BTU Ratings

Match the valve’s flow capacity and stated BTU rating to your appliance. Under-specifying can starve the burner; over-specifying is less common but ensure the valve supports the maximum BTU output of your appliance.

9. Installation And Leak Testing

Use proper gas-rated thread sealant or tape compatible with propane connections. After installation, perform a soap solution leak test or approved leak detection method. If unsure, hire a certified technician to install valves on appliances connected to fixed gas lines or water heaters.

10. Compatibility Perspectives: Water Heater vs Outdoor Heater

Water heater gas valves are often thermostatically integrated and model-specific. Outdoor heater kits usually combine a manual control valve, thermocouple, and sometimes piezo ignition. Do not substitute a water heater valve into a patio heater or vice versa without verifying mechanical and safety compatibility.

11. Replacement Tips And Verification

• Record existing part numbers, thread measurements, and thermocouple types before ordering.
• Compare electrical specs for solenoid valves when replacing valves with thermocouple safety devices.
• Read manufacturer guidance on allowable BTU ranges and environmental operating temperatures.

Using this guide, match thread sizes, pressure ratings, thermocouple specifications, and intended application to choose the right propane heater control valve. For any uncertainty involving gas appliances, consult the appliance manual or a licensed technician to confirm compatibility and ensure safe installation.
