4,500 feet (1,370m) above sea level.
For elevations above 4,500 feet (1,370m) in USA,
installations must be in accordance with the
current ANSI Z223.1/NFPA 54 and/or local codes
having jurisdiction.

Gas Line Installation
When purging gas line the front glass
must be removed.
The gas pipeline can be brought in through the right
side of the appliance. Knockouts are provided at conve-
nient locations to allow for the gas pipe installation and
testing of any gas connection.
The gas line connection can be made with properly
tinned 3/8” copper tubing, 1/2” rigid pipe or an approved
flex connector. Since some municipalities have addi-
tional local codes, it is always best to consult your local
authority and the CSA-B149.1 installation codes.
For USA installations consult the current National Fuel
Gas Code, ANSI Z223.1/NFPA 54.
