Framing and Finishing
1.Choose the unit location.
2.Place the unit into position and secure it to the floor with 1¹⁄₂” (38mm) screws, or nails. The holes to secure the unit to the floor are located just behind the access door grille on the left and right side of the unit.
3.Frame in the fireplace with a header across the top. It is important to allow for the finished wall face when setting the depth of the frame.
4.Attach the fireplace to the frame using the adjustable frame drywall strips (located behind the access door for shipping). Preset the depth to suit the facing material of the wall. The strips are adjustable to 1/2” (13mm), 5/8” (16mm), or 3/4” (19mm). (Figs. 3 & 4)
5.Screw through the slotted holes in the drywall strip and into the

Final Finishing
Noncombustible materials such as brick or tile may be extended over the edges of the face of the fireplace. DO NOT cover any vent or grille panels.
If a Trim Kit is going to be installed on the fireplace, the brick or tile will have to be installed flush with the edges of the fireplace.

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).
Gas Line Installation
When purging gas lines, the front win- dow frame assembly must be removed.
The gas pipeline can be brought in through the rear of the appliance 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 ap- proved flex connector. Since some municipalities have additional local codes, it is always best to consult your local authority and the National Fuel Gas Code, ANSI Z223.1 in the USA or the
