Crown Raptor RPTR085HB in practice
The Raptor RPTR085HB is a heat-only Raptor size: a stainless-steel, gas-fired, direct-vent condensing boiler rated 8.5–85 MBH input with 79 MBH DOE heating capacity and a 69 MBH net AHRI water rating (1.15 allowance) at 96% AFUE per the ratings table (I&O manual Table 2.3; product page). It is designed for installation on a wall with a pre-installed hanging bracket and wall-mount kit (literature PN 980778).
The specifications table lists 2.6 US gallons of water volume, a 30 psig maximum allowable working pressure, 1" copper sweat water connections, a 1/2" NPT gas connection and approximately 110 lb net weight. Venting is direct vent at 2" or 3" with a 30 ft minimum and a 60 ft (2") or 135 ft (3") maximum equivalent length; the boiler measures 33-5/16" high, 19-13/16" wide and 20" deep. The touchscreen Sola-family control includes outdoor reset, domestic hot water priority, three circulator outputs and a built-in sequencer for up to 8 boilers.
Boilers.ca documents this model at model level; boilers ship set for natural gas with LP conversion by optional kit. No official Canadian-sales statement was found, so canadianStatus stays 'unknown'; installation, gas and venting work belongs with a licensed contractor.
Best suited to
- 85-MBH-class residential and light-commercial loads
- Projects wanting 10:1-modulating stainless condensing heat with an outdoor reset sensor
- Cascaded multi-boiler plants using the built-in sequencer (up to 8 boilers)
