400 Series Honeywell Electronic Gas Control Valve
This listing names a 400 Series Honeywell electronic gas control valve. It may suit a buyer who has identified a 400-series control as the required replacement and is comparing that specific product type. The listing information provided does not include detailed operating specifications, fuel type, or appliance compatibility.
Best for: Buyers who can confirm that their appliance calls for the listed 400 Series valve. It was selected because it directly matches the electronic gas-control search, but the model series alone is not enough to establish fit.
Check before buying: Compare the existing valve’s complete part number, appliance documentation, fuel type, and connection requirements with the listing and manufacturer guidance. Do not assume that a valve fits because its series name appears similar.
Limitation: The supplied product details do not specify supported appliances or electrical requirements. Avoid choosing it without confirming those details with a qualified professional.
Fire Magic 1-Hour Gas Shut-Off Valve
This Fire Magic product is an automatic timer designed to shut off gas flow. Its listed features include preset times for gas flow and easy installation. Unlike an appliance’s primary control valve, a timer’s stated purpose is to limit how long gas flows before shutoff.
Best for: Buyers looking for a timed gas shutoff function. It was selected because its automatic shutoff and preset timing features address a different need from replacement valves used to control a fireplace or water heater.
Choose this if: A timed shutoff is the function you need and the product is confirmed suitable for your installation. The listing describes a 1-hour timer, but the provided details do not spell out all timing settings or installation requirements.
Limitation: Do not treat a timer as a substitute for an appliance-specific gas control or assume it fits every grill or gas line. Check the product instructions and consult a qualified installer about suitability.
Dexen 6003K-3V Electronic Natural Gas Valve
The Dexen 6003K-3V is described as an OEM direct replacement for fireplaces, pedestal stoves, and other hearth systems. The listing says it works with 3-volt and IPI electronic control systems found in systems using GM6K series modules. It also specifies adjustable high and low pressure settings for changing flame and heat output.
Best for: Owners of a compatible natural gas hearth appliance who have verified the required valve and control-system details. Its stated 3-volt and IPI support make it more specific than a general-purpose gas-control listing.
Why it stands out: The product details identify the intended appliance category, system types, and high/low adjustment feature. The listing describes it as CSA certified; verify the documentation and exact model for your application.
Limitation: This is not presented as a universal fireplace valve. The stated compatibility does not establish that every 3-volt or IPI appliance will accept it. Confirm the valve number, module, fuel, and manufacturer guidance before installation.
Reliance 100112336 Natural Gas Water Heater Valve
This Reliance natural gas control valve is identified as compatible with A.O. Smith, Reliance, State, and American-branded water heaters. The supplied product details specifically caution that professional installation is appropriate and state that homeowner installation could potentially void a warranty.
Best for: Buyers replacing a natural gas control valve on a water heater that matches the listed brands and exact part requirements. It was selected because it is clearly identified as a water-heater control rather than a hearth valve or timed shutoff.
Check before buying: Compare the existing valve number and the water heater’s model information. Brand names alone do not prove compatibility across all units.
Limitation: The listing calls for professional installation. Do not use this valve for a propane appliance or assume that it fits an unlisted water-heater model.
Reliance 100112338 Liquid Propane Gas Valve
This Reliance water-heater valve is identified as a liquid propane gas valve, with the older part number 9007890005 also shown in its name. The listing associates it with A.O. Smith brands and identifies it as a Honeywell LP gas valve.
Best for: Buyers whose appliance documentation or existing part identifies this specific propane valve or matching part number. It was selected to provide a fuel-specific alternative to the natural gas Reliance control.
Choose this over the natural gas model only if: The water heater is configured for liquid propane and the part number matches the required replacement. Natural gas and propane controls should not be treated as interchangeable.
Limitation: The supplied details do not give a complete compatibility list. Confirm the appliance model and valve number, and have installation handled by a qualified professional.
Buying Guide: How to Choose an Electronic Gas Valve Control
What appliance will the valve control?
Start with the appliance category. A fireplace or pedestal stove valve, a water-heater gas control, and a timed shutoff device perform different roles. A product can be a gas valve without being suitable for your particular appliance. Match the product’s intended use to the appliance manual and existing component.
Do not select a water-heater valve for a fireplace simply because both products control gas. Likewise, an automatic timer intended to shut off gas flow is not necessarily a replacement for the appliance’s primary control valve.
Does the fuel type match?
Identify whether the appliance uses natural gas or liquid propane. The product names distinguish natural gas models from the Reliance LP valve. Fuel type is a key selection requirement, not a minor preference; do not assume that a valve designed for one fuel can be used with the other.
Check the appliance label, manual, and existing valve identification. If the fuel type or conversion status is uncertain, ask a qualified gas-appliance technician before ordering.
How do you verify the correct replacement part?
Use the complete part number printed on the existing control, not just a broad series name or brand. Then check the appliance model and manufacturer’s parts documentation. A replacement should match the required valve, fuel, and control-system specifications.
- Record the appliance brand and full model number.
- Read the existing valve’s full part number and any old or alternate number.
- Compare the listing’s stated application and system requirements with the appliance documentation.
- Ask the manufacturer or a qualified installer to resolve any mismatch or missing information.
This is especially important for the 400 Series listing, for which the supplied product information does not state detailed compatibility. A series label by itself may not identify the correct replacement.
Does the control system need a specific voltage or module?
Some electronic valves are tied to a particular appliance control system. The Dexen listing specifies 3-volt and IPI systems and references GM6K series modules. Those details are useful only when they match the system installed in the appliance. Do not infer compatibility with every electronic ignition system from the word “electronic.”
Check the appliance manual for the control type and required valve. If the system information is unavailable, obtain professional help rather than guessing from appearance or connector shape.
Do you need a valve or a timed shutoff?
Choose a product based on the function required. The Fire Magic timer is described as automatically shutting off gas flow after preset times. The Dexen and Reliance products are appliance-specific valves. A timer may add a timed shutoff function, but the listing information does not establish that it can replace a control valve.
For a timed product, verify the installation application and intended gas connection. For a replacement control, prioritize exact appliance and part-number matching.
Who should install a gas control?
The Reliance natural gas listing explicitly recommends professional installation and warns that homeowner installation could potentially affect warranty coverage. Gas-control work can involve fuel connections and appliance safety, so use the appliance manufacturer’s instructions and applicable local requirements. When a listing or manual calls for professional installation, follow that direction.
Do not install a part if its fuel type, fit, or control requirements are uncertain. A qualified technician can confirm the replacement and installation procedure.
Frequently Asked Questions
Are electronic gas valves interchangeable between appliances?
No. Valve compatibility depends on the appliance, fuel type, part number, and control system. Verify all of these against the appliance documentation before selecting a replacement.
Can I use the Reliance natural gas valve with propane?
The 100112336 listing identifies it as a natural gas control valve. The separate 100112338 listing identifies a liquid propane valve. Do not treat the two as interchangeable; match the valve to the appliance’s specified fuel and part number.
What does IPI mean for the Dexen valve?
The listing states that the Dexen 6003K-3V works with 3-volt and IPI electronic control systems, including hearth systems using GM6K series modules. Confirm that your appliance uses the specified system before choosing this valve.
Is the Fire Magic timer a replacement control valve?
The supplied details describe it as an automatic gas shutoff timer with preset gas-flow times. They do not establish that it replaces an appliance’s primary control valve. Confirm its intended application before installation.
Should a homeowner install a water-heater gas valve?
The Reliance natural gas listing recommends professional installation and notes that homeowner installation could potentially void a warranty. Follow the product and appliance instructions, and use a qualified professional when required.
