This Suburban Nautilus vent is the bit that lets your hot water system breathe through a wall between 2.5 and 5.0 centimetres thick, so it suits most caravan and RV cladding setups without packers. The round face plate sits neat on the outside skin while the inner section lines up with the Nautilus heater outlet, so exhaust gases get pushed straight out instead of spilling into cavities.

The vent is built as a dedicated water heater vent for the Suburban Nautilus range, with a front mesh that keeps bigger debris away from the hot exhaust path. The body depth and collar suit walls from 2.5 to 5.0 centimetres, which covers the usual 1 to 2 inch build-up from frame and cladding. Match it to the 260617 part reference and you have the right bit for standard Nautilus installs.

Q: Does this vent fit all Suburban Nautilus hot water systems?

It fits Suburban Nautilus systems that vent through a wall between 2.5 and 5.0 cm thick. If your wall build-up sits in that 1–2 inch range, this vent lines up with the standard Nautilus outlet position. Always compare the existing vent style and part reference 260617 before ordering. When in doubt, check your heater data plate or manual.

Q: Can I use this vent on walls thicker than 5 cm?

No, this vent is specified for walls between 2.5 and 5.0 cm only. On a thicker wall the inner collar may not reach the heater outlet properly, which can affect exhaust flow. On a thinner wall the vent may sit proud or clamp the panel incorrectly. Stick to the listed thickness range for a proper fit.

Q: Is this vent supplied as a complete assembly?

Yes, it is supplied as a single vent assembly. The unit arrives as the full vent body and face plate ready to be mounted to the wall and heater outlet. You reuse suitable fixings where required to match your existing setup. Always follow the heater manufacturer’s instructions when refitting parts around the exhaust.

Q: How do I confirm my wall thickness before ordering?

The simplest way is to measure the depth of the cut-out where your current vent sits. Remove the old vent and use a ruler or caliper to check from the outer cladding to the inner surface at the heater. If that reading falls between 2.5 and 5.0 cm this vent is in the right range. Taking a clear photo of the opening can also help when asking for advice.

This vent suits Suburban Nautilus Hot Water Systems installed in caravan or RV walls with a thickness between 2.5 cm and 5.0 cm (1–2 inches). Confirm your existing wall thickness and heater model before fitting. Installation follows the standard Suburban Nautilus vent location and mounting pattern.
