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 cur- rent ANSI Z223.1/NFPA 54 and/or local codes hav- ing jurisdiction.

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

Gas Line Installation

When purging gas line, the front window frame removed.

The gas pipeline can be brought in through the rear of the ﬁreplace as well as the bottom. Knockouts are provided on the bottom behind the valve to allow for the gas pipe installation and testing of any gas connection. It is most convenient to bring the gas line in from the rear right side of the valve as this allows fan installation or removal without disconnecting the gas line.

The gas line connection can be made with properly tinned 3/8” copper tubing, 3/8” rigid pipe or an approved ﬂex connector. Since some municipalities have ad- ditional local codes, it is always best to con- sult your local authority and the National Fuel Gas Code, ANSI Z223.1/NFPA 54 in the USA or the CSA-B149.1 installa- tion codes.

Always check for gas leaks with a mild soap and water solution. Do not use an open ﬂame for leak testing.

The gas control is equipped with a captured screw type pressure test point, therefore it is not necessary to pro- vide a 1/8” test point up stream of the control.

When using copper or ﬂex connector use only approved ﬁttings. Always provide a union when using black iron pipe so that the gas line can be easily disconnected for burner or fan servicing . See gas speciﬁcations for pres- sure details and ratings.

The ﬁreplace valve must not be subjected to any test pressures exceeding 1/2 psi. Isolate or disconnect this or any other gas appliance control from the gas line when pressure testing.
