Rheem Professional Classic Plus induced draft gas tank

The Rheem Professional Classic Plus Induced Draft is a compact residential gas storage water heater with a small footprint: Rheem publishes a 29 US gallon capacity in a 17.75 inch diameter cabinet, with a 110 VAC draft inducer that pulls the flue gases through the unit into standard atmospheric Category I double-wall B-vent in 3 inch or 4 inch pipe, a 4 inch adaptor included. The fan-assisted design is the reason the small tank reaches the recovery it does, and Rheem states the recovery rate of 61 gallons per hour at a 90 degrees F rise exceeds a standard 50-gallon by up to 34 percent.

Rheem publishes .70 EF in the product details and lists UEF 0.71 with ENERGY STAR qualification for the model PRO+G29-60N RH70 ID. The stated first-hour performance is 87 gallons in the detailed performance section, while the product summary also carries a 90-gallon first-hour line; WaterHeating.ca records the 87-gallon figure from the performance section. The input is 60,000 BTU/h. The feature set includes the Guardian System air/fuel shut-off device, an integrated self-diagnostic control, a low-NOx burner meeting 40 ng/J, an R-Tech resistored anode rod and the EverKleen sediment-control system, with an enhanced-flow brass drain valve and a factory temperature and pressure relief valve included.

WaterHeating.ca records the efficiency as a legacy EF figure and does not convert it to a UEF. The family is dual certified for potable water and space heating and certified for installation up to 10,100 ft above sea level. Because it uses a draft inducer with a Category I B-vent, the installation manual governs the vent configuration and clearances. Whether CANRO supplies the model is confirmed at consultation.
