Accessories

Rinnai’s line of digital controllers allows you to set water temperature precisely for multiple locations in your home, analyze and troubleshoot the water heater, and even automatically fill your bath to a pre-set temperature and volume. (Note: the MC-91 controller is integrated on the front panel of the RL Series interior units and comes standard with all RL Series exterior units.)

Flexible Installation

For interior installation, Rinnai units use a concentric venting system – a single vent assembly featuring an inner, metal vent for exhaust gases and an outer PVC or metal tube for bringing combustion air from outdoors. The result: a direct-vent, sealed-combustion system that offers optimum safety, performance and ease of installation.

Exterior units can be installed in a recessed enclosure, which can be painted or textured to match your home’s panel or brick siding.

Multiple Units

If you need more than one unit for your larger home, spa or body spray shower, Rinnai’s EZConnect® feature allows you to link two units with a simple cord. For even larger applications, your installer can place up to 25 units in parallel.

Other benefits include:

•Integrated Condensate

Collector: ensures condensation doesn’t drain back into unit, and reduces cost of venting.

•High-Altitude Operation: all RL Series units can be adjusted for use up to 10,200 ft.

INTERIOR ROOF OR WALL VENTING

The Rinnai can be vented vertically or horizontally.

EXTERIOR WALL-MOUNT

installations require no additional venting accessories.
