INSTALLATION
PIPING DETAIL
Gas Connection:
♦
The gas connection supplied is a 1/2” flare connection. The supply pipe can be either rigid or listed flexible connection
and/or copper tubing if allowed by state, provincial and local codes.
♦
In the USA follow local codes and/or the current National Fuel Gas Code, ANSI Z223.1.
♦
In Canada consult local authorities and the CAN/CGA B149 installation codes.
♦
Provide a union downstream of the appliance shut-off valve to allow disconnection of the burner assembly for servicing.
IMPORTANT:
Always check for gas leaks with soap and water solution or gas leak
detector. Do not use open flame for leak detection.
High Altitude:
♦
In the USA the model 2205 is approved for altitudes up to 2000 feet using the factory installed burner orifice. At
elevations above 2000 feet, U.S. codes require a decrease in the input rating by replacing the burner orifice. The input
should be reduced by 4% for each 1000 feet above sea level (see appendix ‘A’). Check local gas utility for orifice size
identification.
♦
In Canada the model 2205 is approved for altitudes up to 4,500 feet (1375 meters). For altitudes above 4,500 feet
(1375 meters) consult the local codes for correct de-rating.
Note: The difference in altitude rating is a requirement of certification standards.
