Dayton 3TZ71 Vent Elbow for Gas Heaters

This Dayton 3TZ71 vent elbow is a flange-mount accessory built for gas-fired infrared tube heaters. It connects to a 4-inch vent opening and provides a 9-inch overall length in galvanized steel. The component is UL Listed and designed for horizontal or vertical vent runs.

Installers fitting Dayton infrared tube heaters

The part suits technicians who need a 4-inch sidewall or roof vent elbow with a flange mount for compatible Dayton heaters. It is not intended for vent systems that require a different diameter, a non-flange connection, or heaters from other manufacturers.

4-inch vent diameter and flange mounting

The critical specification is the 4-inch vent diameter combined with a flange-mount design, which determines whether the elbow matches the heater's vent opening and the installer's connection method.

Highlights

  • UL-listed safety for gas heater venting
  • galvanized steel construction resists corrosion
  • 4 in diameter fits compatible Dayton heaters
  • flange-mount design allows secure sidewall or roof installation

Questions about this item

What flange-mount dimensions does the 4 in vent elbow require for sidewall or roof installation?

The elbow uses a 4 in flange opening with 4 in height and width, and an overall length of 9 in for horizontal or vertical vent runs.

How is the galvanized steel elbow secured to a Dayton infrared tube heater, and what step is often missed?

Align the flange to the heater outlet, fasten with screws or clamps, and seal the joint; the step often missed is applying high-temperature sealant before tightening.

When should the UL-listed galvanized steel elbow be inspected or replaced in a gas-heater vent system?

Inspect annually for corrosion, deformation or loose flange bolts; replace if the steel shows white rust, warping or if the sealant has cracked.
