Do not use this appliance if any part of it has been under water. Immediately call a qualified service technician to inspect the unit and replace any part of the control which has been under water.
These gas inserts are approved for installation in solid fuel burning masonry or zero clearance fireplaces.
Preparation
Before beginning, remove glass door and logs from unit. Also check to make sure there is no hidden damage to the unit. Take a minute and plan out the gas,venting and electrical route. It is best to start with the gas line first followed by the chimney liner. (Refer to Page 9)
Gas Line Installation
When purging the gas line, the front glass must be removed.
If gas piping from the source to the heater location has not been accomplished, install the required pipe. Consult local plumbing code to assure proper pipe size.
The gas pipeline can be brought in through the rear or the base of the heater.
NOTE: The gas line connection can be made of either properly tinned 3/8" copper tubing, 1/2" rigid pipe or an approved flex connector then reduced to 3/8" to the heater. Some municipalities have additional local codes, it is always best to consult your local authority and the CSA- B149.1 installation code.
U.S. Installations consult the current National Fuel Gas Code, ANSI Z223.1
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 provide a 1/8" test point up stream of the control.

Vented Gas Fireplace Heaters
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 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).
When using copper or flex connector, use only approved fittings. Always provide a union when using black iron pipe so the gas line can be easily disconnected for burner or fan servicing. See gas specifications for pressure details and ratings. NOTE: If flex connector is used, it must be kept inside of the heater.
