Condensing Gas Boiler
1 of 6
Engineering Specifications
There shall be provided and installed a quantity of _____ Buderus
GB162/80 wall-hung condensing hot water boiler(s), suitable for induced
draft firing with natural gas or propane. Boiler(s) shall have an AFUE
efficiency 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 firing 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
firing rate shall not exceed 180°F.
Standard equipment shall include a pump group assembly; Grundfos
UP26-99 circulator, integral flow check, supply and return shut-off
valves, pressure gauge, 30psig relief valve and gas supply shut-
off valve. Hydraulic separator option is required for system piping
connection.
Minimal clearances shall be integral to the boiler cabinet design;
a hinged door with locking feature shall be used to access heat
exchanger, burner components, gas valve and sensors.
Integrated controller shall monitor and control all combustion process
functions, control of the boiler water temperature to a value required
by the connected components and shall display current water
temperatures or fault conditions with changes in operation status.
Additional control functions shall include an on/off button, rotary
temperature knobs, LED for burner operation and button for fault
condition reset.
Independent outdoor temperature reset may be accomplished with the
optional AM10 controller; a mounting enclosure shall be included with
the provided resistance dependent sensor.
