High Elevations

Input ratings are shown in BTU per hour and are certified without deration for elevations up to 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.

In Canada, please consult provincial and/or local authorities having jurisdiction for installations at elevations above 4,500 feet (1,370m).

Final Finishing

Noncombustible materials such as brick or tile can be extended over the edges of the face of the fireplace. Do not cover the window frame assembly, any vent, louvre assembly top or louvre assembly bottom. If a Trim Kit is to be installed, brick and tile will have to be installed flush with the side of this appliance.

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 convenient locations to allow for the gas pipe installa- tion 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 additional local codes, it is always best to consult your local authority and the CSA-B149.1installation codes. For USA installations consult the current National Fuel Gas Code, ANSI Z223.1/NFPA 54.
