GB162-80
Condensing Gas Boiler
Boiler Overview
Engineering Specifi cations
There shall be provided and installed a quantity of _____ Buderus
GB162/80 wall-hung condensing hot water boiler(s), suitable for induced
draft fi ring with natural gas or propane. Boiler(s) shall have an AFUE
effi ciency rating of 93.8%.
Boiler(s) shall utilize ALUplus heat exchanger with high quality condensing
heating surface with plasma polymerization for a longer service life and
lower maintenance.
Boiler(s) shall be constructed, tested and labeled in accordance with
ASME Section IV and shall bear the ASME stamp. Boilers shall be CSA
approved and have an applicable Canadian Registration number.
Heat exchanger shall be labeled for 58psig maximum working pressure
rating. An integrated pressure sensor shall ensure minimum and maximum
water pressures are not exceeded.
Boiler shall be capable of modulating fi ring from 100% to 25% of capacity
continuously based upon (i) supply and return water temperatures, and/or
(ii) outdoor reset computerized control. Gross stack temperatures at full
fi ring rate shall not exceed 180°F.
