Please buy from a local dealer. Empire will not warranty any UltraSaver90 Plus wall furnace that is not installed by the selling dealer or that dealer’s direct contract agents.
For all of its technology, the UltraSaver90Plus is surprisingly easy to operate. The built-in control panel lets you operate the wall furnace manually or set the temperature so the system maintains the desired temperature using its built-in thermostat.
Creating Heat – The power-vent blower draws in an ideal charge of air (White Arrow) to support combustion.
The high-efficient in-shot burners generate the heat (Orange Arrows). (Two burners in the PV35 and one in the PV18). The two-stage heat exchanger consists of a large-diameter tube and multiple small-diameter stainless steel finned tubes. Each transfers progressively more heat.
Cooled exhaust exists the heater via PVC (or Empire approved Poly vent pipe) at 110 to 120 degress F (Green Arrows).
Circulating Heat – The blower pulls room air (Blue Arrows) into the top of the heater and forces it across the heat exchanger. The warm air (Red Arrows) exists throught the bottom louvers at the front of the heater.
Thanks to its super-high efficiency the US90 uses widely available 2-inch PVC pipe or Empire approved Poly pipe for venting. Using PVC requires just a fraction of the material cost and labor involved in steel vent pipe. PVC pipe fits easily inside a standard stud wall, eliminating the additional framing and clearances required for metal vent pipe.
Because the US90 has a power vent, the 2-inch PVC pipe can run up to 50 feet to terminate vertically through the roof or horizontally through an exterior wall
