In cooperation with CSA International, Rheem Canada Ltd. of Hamilton, Ontario is voluntarily recalling approximately 1107 Paloma, Rheem and Richmond power vent 199,900 BTU tankless, indoor water heaters in Canada. Certain components inside the units may shift during transit, causing an air filter door switch to operate improperly. If the switch fails and the air filter door is out of place, the water heater may continue to operate and dust and lint could build up, posing a carbon monoxide poisoning hazard.

No incidents or injuries have been reported.

The recall involves the following models:

Paloma Brand Models:PTG-74PVN, PTG-74PVP, PTG-74PVNH, PTG-74PVPH


Rheem Brand Models:RTG-74PVN, RTG-74PVP, GT-199PV-N

Richmond Brand Models:RMTG-74PVN

The serial numbers of units under voluntary recall are 15 characters long and are as shown in the example below:


Only those units with the 5th through 8th serial number characters (eg. “0706” in example above ) that range from 0904 (ie. Sept 2004) through 0706 (ie. July 2006) are suspect.

Models within this range of serial number (ie. 0904 through 0706) that carry a “circular purple sticker” attached to the bottom of the heater and the carton label have been repaired and are, therefore, not affected by this recall.

No other tankless or tank-type water heaters are affected by this recall program and no action is required for other models.

The water heaters were sold at major home centres and through plumbing supply distributors nationwide from October 5, 2005 through December 8, 2006.

Consumers with the recalled water heaters should stop using them immediately if the air filter door is not in place. Consumers who have not already been contacted by an authorized contractor should immediately contact their installer or Rheem Canada Ltd. to arrange for a free on-site repair. For more information, contact Rheem Canada toll free at 1-800-268-6966 ext. 364 between 8:30 a.m. and 4:30 p.m. ET Monday through Friday or visit the Rheem Canada website at

Consumers are reminded to use the air filter door for these water heaters to avoid a carbon monoxide hazard.
