Bradford White RG1PV40S6N19 in practice
The RG1PV40S6N19 is the 40-gallon member of the first-generation RG1PV power vent line, which Bradford White still lists in Canada alongside the second-generation RG2PV. At the same 40,000 BTU/h input and 75 US gallon (284 L) first-hour rating as the RG2PV40S6N, its differences are physical: a narrower 20 in (508 mm) jacket and a UEF of 0.68 against the RG2PV's 0.72, reflecting the older control generation.
It is a Defender Safety System flammable-vapour-ignition-resistant tank that vents through 2, 3 or 4 in PVC-family pipe under positive pressure, with no chimney required, and needs a 120 VAC, 3.1 A supply for the blower and electronic ignition. The current catalog number ends in 19 (RG1PV40S6N19); the Canadian spec sheet prints the same model as RG1PV40S6N. Whether CANRO stocks this model for a given job is confirmed at consultation.
Best suited to
- Like-for-like replacement of an existing RG1PV power vent tank with a serviceable vent run
- Narrow spaces where the 20 in jacket fits and a chimney is unavailable
- Homes that want Defender flammable-vapour resistance without a flue
Limitations to know
- Requires a 120 VAC receptacle; no hot water during a power outage
- UEF 0.68 is below ENERGY STAR and below the RG2PV generation's 0.72
- Blower and electronic control add points of failure the atmospheric line does not have
- Warranty excludes labour and anode consumption; anode inspection every 2 years is required

Maintenance the manufacturer specifies
- Inspect the anode rod every 2 years and replace when depleted; more often with softened water (manual, Maintenance item 9).
- Operate the T&P relief valve at least once a year to check it lifts and reseats without leaking (item 6).
- Drain about a gallon monthly to remove sediment (item 7); annual inspection by a qualified technician.
- Inspect the vent system at least once a year; check burner flames twice a year (items 10 and 4).

Services
Hot water and scalding
- Water above 49 °C at a tap can scald in seconds, and children and older adults are at most risk. BC's plumbing code limits shower and bathtub water to 49 °C.
- Storage tanks are normally kept hotter (Health Canada advises 60 °C) to limit Legionella growth, with a thermostatic mixing valve tempering the water to the fixtures.
- Never bypass or remove a mixing valve, thermostat or high-limit control to get hotter water.
Official guidance: Government of Canada on water temperature and scalds and HealthLinkBC.
Frequently asked questions
Is the RG1PV40S6N19 sold in Canada?
Yes. The RG1PV power vent family is listed on Bradford White's Canadian residential gas page and on Canadian spec sheet C1261, which prints the model as RG1PV40S6N. The 19 suffix is the catalog form of the same current unit.
What is the difference between the RG1PV and RG2PV generations?
The RG2PV units carry the current control and rate UEF 0.72 against 0.68 for the RG1PV at the same input; the RG2PV short form also uses a wider 22 in jacket. Both are current in the Canadian catalog.
Can the RG1PV40S6N19 run on propane?
The propane version is the RG1PV40S6X19 with a 38,000 BTU/h input. Fuel conversion is not a field procedure; order the correct fuel version.
