Utica Boilers UB90-200 Installationsanweisungen

Boiler is equipped for residential installations. If used for 

commercial applications; additional code requirements 

must be adhered to. This may require additional controls, 

including but not limited to manual reset low water cut off, 

manual reset high temperature limit, and wiring and/or 

piping modifications.

Installation must conform to the requirements of the 

authority having jurisdiction or, in the absence of such 

requirements, to the National Fuel Gas Code, ANSI 

Z223.1/NFPA 54 and/or Natural Gas and Propane 

Installation Code, CAN/CSA B149.1.

Where required by authority having jurisdiction, 

installation must conform to the Standard for Controls 

and Safety Devices for Automatically fired Boilers, 

ANSI/ASME CSD-1.

Be certain gas input rate is correct. Over-firing may 

result in early failure of boiler components; this may 

cause dangerous operation. Under-firing may result in 

too much air for pre-mix burner causing poor or loss of 

combustion.

Never vent products of combustion from this boiler to 

enclosed space. Always vent to outdoors. Never vent to 

another room or to inside building.

Verify adequate outdoor air supply to boiler for 

complete combustion.

Follow regular service and maintenance schedule for 

efficient and safe operation.

Keep boiler area clean of debris and free from 

combustible materials, gasoline and other flammable 

vapors and liquids.

Proper through-the-wall or through-the-roof 

combustion venting shall be in accordance with 

materials and methods described in this manual. 

Installation must comply with local codes.

• Verify you have selected the boiler with proper capacity 

before continuing installation. AHRI Rating of boiler 

selected should be greater than or equal to calculated 

peak heating load (heat loss) for building or area(s) served 

by boiler and associated hot water heating systems. See 

“Boiler Ratings & Capacities” on page 3.

• Heat loss calculations should be based on approved 

industry methods. 

Before selecting boiler location, consider following. 

• Supplied with correct type of gas (natural gas or 

propane).

• Connected to suitable combustion air intake piping 

system to supply correct amount of fresh (outdoor) air
