METAL FAB

METAL FAB is a manufacturer of venting components for gas-fired appliances, with a product line centered on concentric vent terminations and vent pipe kits for water heaters. The brand supplies components designed for Category IV positive-pressure venting systems, commonly used with condensing water heaters and boilers. METAL FAB components are constructed from corrosion-resistant materials, typically aluminum or stainless steel, to withstand the acidic condensate produced by high-efficiency appliances. The concentric vent design integrates both the exhaust and intake air passages into a single pipe assembly, simplifying installation and reducing the number of roof or wall penetrations required. METAL FAB vent pipe kits are available in multiple lengths—6 in, 12 in, 24 in, and 36 in—and include elbows in 45-degree and 90-degree configurations, allowing for flexible routing in tight mechanical spaces. All listed components are rated for BTU ranges up to 199K BTU, making them suitable for residential and light commercial water heater applications. The vent connection size is 3 in for the inner exhaust pipe and 5 in for the outer intake pipe, conforming to common concentric vent standards. Mounting orientations include vertical and horizontal, with specific part numbers for each configuration. 3G Electric stocks a range of METAL FAB vent pipe kits and elbows, providing procurement specialists and maintenance managers with a single source for these components. The inventory includes both straight pipe sections and elbows, enabling complete vent system assembly from a single purchase order. Each SKU is identified by its manufacturer part number, facilitating cross-referencing with existing system specifications. The components are designed for straightforward field assembly, with locking bands and gaskets included to ensure a gas-tight seal. For engineers specifying vent systems for condensing water heaters, METAL FAB offers a standardized solution that meets the venting requirements of appliances with inputs up to 199K BTU. The concentric design also reduces heat loss compared to separate exhaust and intake runs, contributing to overall system efficiency. 3G Electric supports these products with logistics capabilities for global shipment, ensuring that replacement or new-installation components are available when needed.

Frequently asked questions

Common questions about METAL FAB from 3G Electric.

What is the maximum BTU rating for METAL FAB concentric vent terminations?

The METAL FAB concentric vent terminations listed by 3G Electric are rated for BTU ranges up to 199K BTU. This rating applies to all SKUs in the RTG20151 and RTG20251 series, including straight pipe sections and elbows. For appliances exceeding this input, consult the manufacturer's specifications for alternative venting solutions.

What connection sizes are available on METAL FAB vent pipe kits?

METAL FAB vent pipe kits for water heaters feature a 3-inch inner exhaust connection and a 5-inch outer intake connection. This concentric configuration is standard for many condensing water heaters and boilers. The 3 in/5 in size is consistent across all listed SKUs, including straight pipes and elbows.

Can METAL FAB vent pipe elbows be used in both horizontal and vertical orientations?

Yes, METAL FAB offers elbows in 45-degree and 90-degree configurations that are suitable for both horizontal and vertical mounting. The 45-degree elbow (MPN RTG20151GB) is listed as horizontal/vertical, while the 90-degree elbow (MPN RTG20151GA) is specified for horizontal orientation. Always verify the orientation requirements of your specific installation before selecting components.

What materials are used in METAL FAB concentric vent terminations?

METAL FAB concentric vent terminations are constructed from corrosion-resistant materials, typically aluminum or stainless steel, to handle the acidic condensate produced by high-efficiency condensing water heaters. The specific material composition may vary by part number; consult the product datasheet for exact specifications. The components are designed for Category IV positive-pressure venting systems.

Are METAL FAB vent pipe kits compatible with all water heater brands?

METAL FAB vent pipe kits are designed for use with condensing water heaters and boilers that require a concentric vent system with a 3 in/5 in connection size. Compatibility depends on the appliance's vent connection type and BTU rating. Always verify that the appliance manufacturer specifies a concentric vent system and that the BTU input does not exceed 199K BTU. Cross-reference the appliance's installation manual with the METAL FAB part number.
