(Dealer or authorized representative who certifies that this appliance is installed in accordance with Manufacturer’s instructions and local codes.)

1)   Seal any unused openings in the venting system.
2)   Inspect the venting system for proper size and   
      horizontal pitch, as required in the National Fuel  
      Gas Code, ANSI Z223.1/NFPA 54 or the Natural Gas  
      and Propane Installation Code, CSA B149.1 and  
      these instructions. Determine that there is no  
      blockage or restriction, leakage, corrosion and other  
      deficiencies which could cause an unsafe condition.
3)   As far as practical, close all building doors and  
      windows and all doors between the space in which  
      the appliance(s) connected to the venting system  
      are located and other spaces of the building.
4)   Close fireplace dampers.
5)   Turn on clothes dryers and any appliance not    
      connected to the venting system. Turn on  

 

      any exhaust fans, such as range hoods and  

 

      bathroom exhausts, so they are operating at    
      maximum speed. Do not operate a summer  
      exhaust fan.

      WARNING:

 

CARBON MONOXIDE POISONING HAZARD

Failure to follow the steps outlined below for each appliance connected to the venting system being placed  
into operation could result in carbon monoxide poisoning or death.

The following steps shall be followed for each appliance connected to the venting system being placed into 
operation, while all other appliances connected to the venting system are not in operation:

6)   Follow the lighting instructions. Place the appliance  

 

      being inspected into operation. Adjust the thermostat  
      so appliance is operating continuously.
7)   Test for spillage from draft hood equipped appliances  
      at the draft hood relief opening after 5 minutes  

 

      of main burner operation. Use the flame of a match  
      or candle.
8)   If improper venting is observed during any of the  
      above tests, the venting system must be corrected  
      in accordance with the National Fuel Gas Code,  
      ANSI Z223.1/NFPA 54 and/or Natural Gas and Propane    
      Installation Code, CSA B149.1.
9)   After it has been determined that each appliance  

 

      connected to the venting system properly vents  
      when tested as outlined above, return doors, windows,  
      exhaust fans, fireplace dampers and any other  
      gas-fired burning appliance to their previous  
      conditions of use.

ANY WARRANTY CONSIDERATIONS ARE CONTINGENT ON INSTALLATION 

BY A QUALIFIED INSTALLER (CONTRACTOR). SELF-INSTALLATION IS 

PROHIBITED AND WILL INVALIDATE YOUR WARRANTY.
