LOCHINVAR

Lochinvar is a manufacturer of high-efficiency water heating and boiler systems, with a product line that extends to HVACR components used in commercial and industrial hydronic systems. The company, founded in the United States, is known for its condensing boiler technology and integrated control systems. 3G Electric supplies a range of Lochinvar replacement parts and accessories, including combustion air boosters, ignitor gasket kits, indicator lights, burner assemblies, circulating pumps, ignition modules, and inducer assemblies. These components are designed to support the maintenance and repair of Lochinvar heating equipment, which is commonly specified in applications requiring reliable hot water supply and space heating. The parts available through 3G Electric cover key subsystems: combustion (burner assemblies, ignition modules, air boosters), hydronic circulation (circulating pumps with bronze volutes, flanged connections, and 1/6 hp motors rated for 120V AC), and electrical/control (indicator lights, ignitors). Build standards for these components align with OEM specifications, ensuring compatibility with Lochinvar's residential and commercial boilers, such as the Knight, Shield, and Power-Fin series. For technical buyers, the circulating pump (SKU 42FK13) offers a flow rate of 30 gpm and a maximum head of 15 ft, with a face-to-face dimension of 8.5 inches, suitable for hydronic system retrofits. The combustion air booster (SKU 42FJ04) is a direct replacement for models requiring forced draft, with part number 100137145. Ignition modules (SKU 40LY34) and burner assemblies (SKU 42FJ08) are critical for reliable startup and flame control. 3G Electric supports these lines with datasheets that include dimensional drawings, electrical ratings, and material specifications, enabling engineers to verify fit and performance before ordering. Logistics support covers global shipping, with inventory maintained for common replacement intervals. The product range emphasizes durability: bronze pump volutes resist corrosion in closed-loop systems, and indicator lights (SKUs 50PM36, 62YA69) are rated for panel mounting in control cabinets. By stocking OEM-sourced parts, 3G Electric helps maintenance managers reduce downtime for Lochinvar-equipped facilities, from hospitals to manufacturing plants.

Frequently asked questions

Common questions about LOCHINVAR from 3G Electric.

What is the typical application for the Lochinvar circulating pump (SKU 42FK13)?

The Lochinvar circulating pump (SKU 42FK13) is used in hydronic heating systems to move water through boilers, radiators, or heat exchangers. It has a 1/6 hp motor, 120V AC power, bronze volute, and flanged connections. With a flow rate of 30 gpm and a maximum head of 15 ft, it is suitable for residential and light commercial systems where corrosion resistance is needed. The 8.5-inch face-to-face dimension allows direct replacement in many Lochinvar boiler models.

How do I verify compatibility of a Lochinvar ignition module (SKU 40LY34) with my boiler?

The Lochinvar ignition module (SKU 40LY34, part number RLY3002) is designed for use in specific Lochinvar boiler models. To verify compatibility, check the boiler's service manual or the existing module's part number. The module controls spark ignition and flame sensing. Ensure the electrical ratings (typically 120V AC) match your system. 3G Electric provides datasheets with wiring diagrams and model cross-references to assist with verification.

What is the function of the Lochinvar combustion air booster (SKU 42FJ04)?

The Lochinvar combustion air booster (SKU 42FJ04, part number 100137145) is a fan assembly that supplies forced air to the burner for proper combustion. It is used in boilers with sealed combustion or direct vent systems where natural draft is insufficient. The booster ensures correct air-to-fuel ratio, improving efficiency and reducing emissions. It is a direct replacement part for specific Lochinvar models and should be installed per the manufacturer's instructions.

Are Lochinvar indicator lights (SKUs 50PM36 and 62YA69) interchangeable?

Lochinvar indicator lights SKU 50PM36 (part number 100208306) and SKU 62YA69 (part number 100208305) are not interchangeable without checking specifications. They may differ in voltage rating, color, or mounting type. Both are used on control panels to show system status (e.g., power on, fault). Refer to the datasheets for electrical ratings and dimensions. 3G Electric can provide these details to ensure correct selection for your panel.

What maintenance is required for a Lochinvar burner assembly (SKU 42FJ08)?

The Lochinvar burner assembly (SKU 42FJ08, part number BNR3707) should be inspected annually for soot buildup, corrosion, or damage. Clean the burner ports with a soft brush and vacuum. Check the flame pattern for even distribution. Replace the ignitor gasket (SKU 62YA65) if leaks are present. Always follow the boiler's service manual for torque specifications and safety procedures. 3G Electric stocks replacement gaskets and seals for this assembly.

Can the Lochinvar inducer assembly (SKU 40LY31) be used in any boiler model?

The Lochinvar inducer assembly (SKU 40LY31, part number FAN2714) is model-specific. It is designed for use in certain Lochinvar condensing boilers to exhaust flue gases. Using it in an incompatible model may cause improper venting or performance issues. Check the boiler's parts list or contact 3G Electric with your boiler model number to confirm fit. The assembly includes the fan motor and housing, and should be replaced as a unit.
