RinnaiEX38DTP Direct Vent Wall Furnace, Indoor Propane Heater, Energy Efficient Space Heater, 36,500 BTU, Beige

We received our order on time and it was as described.

Was an excellent buy; good product

So quiet. Nice features.I actually vented it into a utility room outside the heated conditioned space and then extended the exhaust vent through the exterior wall with stainless steel tubing ( 6 feet of 1.5" 304 SS tubing from Zoro cost ~$50 and its ID is 1 mm larger than the Rinnai exhaust pipe OD so its a pretty good slip fit for a tack weld or muffler clamp. The alternative would have been about $400 in Rinnai vent extensions ... I think Rinnai might want to rethink its direct vent furnace extensions. They are so complicated compared to direct vent furnaces that use regular PVC fittings, but I understand that the Rinnai exhaust temp is probably too high for PVC. But a simple factory approved adaptor to standard 1.5" SS 304 tubing would be nice. )

We needed a modern styled, direct vent heater for a 450 sq-ft four season room. One that could be safely vented thru an existing plexiglass window. We found it with this “Rinnai Unit”.Installation instructions were clear, straight forward. The unit is well-constructed, easily serviced with any possible replacement/service parts available online. It has received many compliments on its performance from dinner guests on its exceptionally high heat output and its quite operation.Its automatic variable heat output based on the rooms heating needs, its ease of programing two independent time/temperatures and being able to program it to maintain a minimum room temp just makes a well thought out design and top-of-the-line unit.

Connect the wire from the R (or Rh) terminal on the thermostat to one of the transformer's "AC" terminals . Connect to the other "AC" terminal:-one of the black wires from the relay and-the wire from the C (common) terminal on the thermostat.So, one side of the transformer AC will have a single wire connected (to R), while the other side will have two wires connected: a black wire from the relay and the C (common) wire leading to the thermostat.Next:• The second black wire from the relay connects directly to the W terminal on the thermostat.

It works great just a little noisy. Would highly recommend it.

Excellent heater. Keeping our living space very comfortable. I want to put one in our sunroom next.

This little heater heats my 600 sq, foot, well insulated home but I wouldn't recommend anything bigger.
