10002264 / SRV10002264 Natural Gas 3-Way Pilot Assembly Kit

Key Features

  • Comprehensive 3-Way Pilot System: A complete ignition solution featuring the pilot burner hood, a high-output thermopile, a precision thermocouple, and a ceramic electrode, ensuring reliable ignition and flame sensing.
  • Dual-Sensor Safety Technology: Utilizes both a thermocouple (to verify the pilot flame) and a thermopile (to generate the millivolts required to open the main gas valve), providing redundant safety and electrical independent operation.
  • High-Temperature Stainless Steel Hood: The 3-way pilot hood is manufactured from corrosion-resistant stainless steel, designed to direct the flame precisely toward the sensors and the main burner for a smooth "cross-over" ignition.
  • Precision NG Orifice: Pre-installed with a Natural Gas (NG) orifice calibrated for optimal fuel-to-air mixing, resulting in a stable, blue pilot flame that resists drafting and lifting.
  • Heavy-Duty Lead Wires: Features 24-inch heat-shielded lead wires for both the thermocouple and thermopile, allowing for flexible routing away from the high-heat zones of the firebox.

Compatibility & Fitment

This 3-way pilot assembly is the primary ignition component for millivolt (standing pilot) fireplaces manufactured by Hearth & Home Technologies (HHT). Key compatible brands include:

  • Majestic: Fits various models in the DVR, DVRT, DVS, and DVT series (e.g., DVR33, DVT36, DVRT42).
  • Vermont Castings: Compatible with many Direct Vent and B-Vent units including the Radiance and Stardance series.
  • Monessen: Fits standard millivolt series such as the BDV, CDV, and MDV units.
  • Temco: Direct replacement for several ADVP and DV series fireplaces utilizing the SIT-style pilot bracket.
  • Note: This kit is configured for Natural Gas. To use with Propane (LP), you must swap the internal pilot orifice (typically a #35 or #51 depending on the model).

When to Replace

  • Pilot Will Not Stay Lit: After releasing the knob, the pilot flame goes out instantly. This indicates a failed Thermocouple that can no longer hold the safety magnet open.
  • Main Burner Won't Ignite: The pilot is lit, but the main logs never turn on. This suggests the Thermopile is not generating the required 325–750 millivolts to trigger the gas valve.
  • Sooting or Yellow Flame: The pilot hood or orifice is clogged with carbon or spider webs, causing an "unclean" flame that prevents the sensors from heating properly.
  • No Spark During Lighting: The ceramic insulator on the electrode is cracked or the wire is frayed, preventing the piezo igniter from creating a spark to light the pilot.
  • Delayed Ignition: The pilot flame is weak or misdirected, causing gas to build up before the main burner finally "poofs" or bangs during ignition.

Installation Tips

  • Safety First: You MUST shut off the gas supply and ensure the fireplace has completely cooled. Gas fireplace interiors can retain dangerous levels of heat long after use.
  • The "Millivolt" Test: Before replacing the whole assembly, use a multimeter to check the thermopile. If it reads above 325mV while the pilot is hitting it, your problem might be the gas valve or the wall switch, not the pilot kit.
  • Avoid Kinking: The thermocouple and pilot tube are made of soft copper/aluminum. Be extremely careful not to "kink" the lines during routing, as this can restrict gas flow or break the internal sensor wire.
  • Finger-Tight Plus: Thread the thermocouple nut into the back of the gas valve by hand until snug, then give it only a **1/4 turn** with a wrench. Overtightening can crush the sensitive internal copper connection.
  • Clean the Orifice: If you are re-using your old pilot tube, ensure the orifice is clear of debris. Never use a drill bit to clean an orifice; use compressed air or a fine needle to avoid enlarging the hole.

Power Chewer Loves This!
Size: Medium, Color: Antler
This is my dog's new favorite chew! She loves that she can hold it in her paws. I think she really loves the taste and texture of it. I don't give her antlers as I have heard too many horror stories about broken teeth. I also don't give her nylon toys as I have also heard a lot of horror stories of broken teeth as well as concerns about them digesting the plastic. This is between antlers and bully sticks, which is perfect for a power chewer. I feel comfortable with her eating the pieces that flake off this toy. She loves chewing and she will default to this toy when she wants to help calm down. I don't notice much of a smell. It does flake, but not enough I will even take a star off. Plus, it's plant based and vacuums up easily once dried. It doesn't capture her attention as much as bully sticks or beef cheek chews, but it's much less expensive over time and doesn't stink up our living room! She will also always pick this over any of her rubber chews. Great product and recommend it for all the power chewers.

Crumbly, odd texture
Size: Large, Color: Duo Pack
Neither of my dogs were very interested in these. They did chew on the antler-shaped versions more so than the infinity-style versions. When they did chew on these, they didn’t hold up well or last long. These have a strange, crumbly texture when chewed. You’ll find bits and pieces of these chews where the dogs have been chewing. Will not be reordering.

This appears to be a good alternative to the hard plastic chew toys.
Size: Large, Color: Duo Pack
My dog is a heavy chewer. I decided to try this brand out after using a different brand for quite awhile. while my dog seems to like it and carries it around (the pretzel shaped one) he doesn't seem to attack it as whole heartedly as his old brand, I'm thinking it might be the shape, we will see when he wears it out and I switch him to the antler shape. What I like most about it is it doesn't tear my hand up like the other brand did after he had been chewing it for awhile. While it is wearing down some it seems to do it in a more mild manner. Since we haven't had it long I would give this 3.5 stars because I don't know if it will last as long and not sure f it is just the shape that has him more mellow with it.

Choose your shape
Size: Medium, Color: Duo Pack
I love the idea of the dogs not eating nylabone plastic so have been searching for "healthier" options that last for heavy chewers. Two German Sherpherds, they are not big fans of the circular shaped toy but love the antler shaped one and even with both chewing on it, has not been destroyed yet and is not cutting their gums open. I am not finding pieces laying in the carpet. Recommend this
