Utica Boilers SSV Installationsanweisungen

This boiler requires a dedicated vent system. Install 

combustion air and vent piping in accordance with these 

instructions, authority having jurisdiction, and:  

• USA - National Fuel Gas Code, ANSI 223.1/NFPA 54.
• Canada - Natural Gas and Propane Installation Code, 

CAN/CSA B149.1

Vent connections serving appliances vented by natural draft 

shall not be connected into any portion of mechanical draft 

systems operating under positive pressure.
Install vent system in accordance with these instructions.

When existing boiler is removed from common venting 

system, common venting system is likely to be too large for 

proper venting of appliances remaining connected to it. 
After removal of existing boiler, following steps shall 

be  followed with each appliance remaining connected to 

common venting system placed in operation, while other 

appliances remaining connected to common venting system 

are not in operation:

• Seal any unused openings in common venting system.
• Visually inspect venting system for proper size and      

horizontal pitch. Determine there is no blockage or 

restrictions, leakage, corrosion and other deficiencies 

which could cause an unsafe condition.

• When practical, close all building doors, windows, and 

all doors between space in which appliances remaining 

connected to common venting system are located 

and other spaces of building. Turn on clothes dryer 

and any appliance not connected to common venting 

system. Turn on exhaust fans, such as range hoods and 

bathroom exhaust so they will operate at maximum 

speed. Do not operate summer exhaust fan. Close 

fireplace dampers.

• Turn on appliance being inspected. Follow lighting         

instructions. Adjust thermostat so appliances will operate 

continuously.

• Test for spillage at draft hood relief opening after 5    

minutes of main burner operation.  Use flame of match or 

candle, smoke from cigarette, cigar or pipe.

• Determine each appliance remaining connected to  

common venting system properly vents when tested 

as outlined above. Then return doors, windows,              

exhaust fans and any other gas-burning appliance to 

their previous condition of use.

• Any improper operation of common venting system 

should be corrected so installation conforms with National 

Fuel Code, ANSI Z223.1/NFPA 54 and/or Natural Gas 

and Propane Installation Code, CAN/CSA B149.1. 

When re-sizing any portion of common venting system, 

common venting system should be re-sized to approach  

minimum size as determined using appropriate tables in 

Chapter 13 of the National Fuel Gas Code, ANSI Z223.1/

NFPA 54 and/or Natural Gas and Propane Installation 

Code, CAN/CSA B149.1.
