Reliance Water Heater Gas Control Valve 100112336
The Reliance/ Honeywell gas control valve 100112336 is designed for upright mounting and supports a modest ambient temperature range from 0°C to 60°C. It uses 1/2 inch NPT connections (inlet/outlet) and an inverted flare configuration. The regulator is rated around 5.0 inches of water column (in. Wc) with a typical gas flow capacity of 30 to 75 cubic feet per hour. This valve is commonly installed in residential natural gas water heaters and is valued for straightforward replacement in models that require the same valve footprint. When selecting this valve, verify the cavity fit and ensure the plumbing lines align with the 1/2″ NPT ports. Pricing, availability, and compatibility vary by model year and heater brand. Compatibility notes emphasize matching the model and serial number to confirm proper fit. Safety considerations include proper venting alignment and adherence to local codes during replacement.
Reliance Water Heater Natural Gas Control Valve 100112336
This variant emphasizes thermostat compatibility with a range of common water heater brands, including A.O. Smith, Reliance, State, and American-branded units. The listing notes that customers should provide the heater’s model and serial number to confirm a correct fit. This warning reflects the variability in valve assemblies across brands and model years. For installers, this means double-checking compatibility before purchase to avoid misfit and delays. The valve’s key advantage is its compatibility breadth, but buyers should verify exact fit with their existing control valve pocket and gas line configuration.
Rheem AP14270G Gas Control Thermostat
The Rheem AP14270G is a gas control thermostat designed to regulate gas flow to the burner and maintain a steady water temperature. It is marketed as an OEM genuine factory-authorized part, reinforcing compatibility with Rheem systems and potentially other brands that use similar control interfaces. Installation considerations include verifying the exact model number and ensuring the thermostat wiring terminals align with the heater’s electrical system. This valve is suitable for confident DIYers or professional technicians seeking an authentic replacement part that aligns with Rheem’s original specifications.
Stanbroil Low Pressure Propane Gas Flame Failure Safety Valve Kit
This Stanbroil kit targets propane systems and focuses on flame safety. It supports a low working pressure ceiling of 1/2 psi (65 mbar) and includes a main control valve with 3/8″ male flare threads. The package typically includes a thermocouple and a Bakelite knob for easy operation. It is designed for use with fireplaces, fire pits, and heaters, making it a versatile option for propane-based heating appliances. Installation safety includes verifying gas line pressures and ensuring the flame sensor is correctly positioned for reliable shut-off in case of flame failure.
Stanbroil One Stop Gas Appliance Hook Up Kit
This all-in-one Stanbroil kit combines a brass gas ball valve, a flexible gas connector, and necessary fittings for easy hookup to gas appliances. The kit features 1/2″ OD x 3/8″ ID connectors with a 22″ stainless steel flexible hose and 1/2″ female flare ends on both sides, plus a 1/2″ brass shut-off valve with NPT threading. The configuration supports straightforward installation for garage heaters, stoves, wall-mounted heaters, fireplaces, and dryers in many residential settings. When using this kit, ensure compliance with local gas codes and verify the connector lengths suit the installation space.
MENSI Low Pressure LPG Propane Gas Valve Kit With Flare Swivel
The MENSI kit is designed for low-pressure LPG propane applications and features a male flare swivel connection. It supports a working pressure up to 1/2 psi (65 mbar) and includes a 3/8″ male flare connection. The set emphasizes a compact design with a Bakelite knob and a 600mm thermocouple lead. It is suitable for flame control in gas fireplaces, pits, and heaters. As with similar kits, ensure the valve configuration and shank dimensions match the existing heater setup to guarantee proper fit and safe operation.
Buying Guide: Key Considerations For Choosing A Gas Valve
When selecting a gas valve for a heater, homeowners and technicians should evaluate several factors to ensure safety, compatibility, and long-term reliability. The following considerations help compare different valves and decide which is best for a given heater model and fuel source.
- Fuel type compatibility: Confirm whether the valve is rated for natural gas or propane (LP). Some items are designed for both, but many are fuel-specific, and using the wrong fuel can be dangerous.
- Connection standards: Look at inlet/outlet sizes (1/2″ NPT, 3/8″ flare, etc.) and threading. Ensure your heater’s piping matches or you can source appropriate adapters.
- Pressure and regulator specs: Check the operating pressure (often stated in inches of water column or psi). Valves must match the heater’s gas supply pressure and the regulator requirements of the system.
- Temperature and ambient range: Valves tolerate certain ambient temperatures. Installations in unheated spaces may require components rated for lower temperatures.
- Thermostat compatibility and OEM accuracy: For valves labeled as thermostat compatible, verify the model compatibility with your heater brand and unit year. OEM-approved replacements typically ensure a smoother fit.
- Safety features: Look for flame failure protection, robust flame sensing, and proper shut-off mechanisms. Some kits include thermocouples and safety valves as part of the package.
- Durability and material quality: Brass and stainless steel components offer durability and resistance to corrosion, especially in humid or outdoor environments.
- Installation considerations: Some valves require professional installation due to gas line work, leak testing, and code compliance. Always follow local codes and safety guidelines.
- Replacement and compatibility notes: Some models require precise matching of model numbers, serial numbers, and cavity dimensions. Keep maker documentation handy during replacement planning.
Additional Perspectives: How To Decide Between Models
For homeowners seeking straightforward replacements, OEM authentic parts (like Rheem AP14270G or Reliance/Honeywell combinations) offer predictable compatibility with existing equipment. In contrast, universal or kit-style options (Stanbroil and MENSI) provide flexible fit across brands and configurations, but may require careful verification of threading, shank size, and pressure ratings. Safety-focused kits with flame failure protection and thermocouples are particularly important for propane appliances exposed to outdoor conditions or frequent cycling. Finally, always verify the heater’s model and serial number to ensure the chosen valve matches the exact cavity and port arrangement of the original equipment.
In scenarios where a heater is older or discontinued, replacement parts from related brands or similar models that use the same connection standards can keep the system running. If in doubt, consult a licensed technician to perform a leak test and a functional check after installation. This approach minimizes risk and helps protect household occupants from gas-related hazards.
