GENERAL VENTING INSTRUCTIONS

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:
 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 CAN/CGA 
B149  Installation  Codes  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.

  6.  Follow  the  lighting  instructions.  Place  the  appliance 

being  inspected  into  operation.  Adjust  the 
thermostat so appliance is operating continuously.

  7.  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 Z221.1/NFPA  54  and/or  CAN/CGA  B149 
Installation Codes.

  8.  After  it  has  been  determined  that  each  appliance 

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