High Altitude Installation
When installing this unit at an elevation above 2000 feet (in the
United States) it may be necessary to decrease the input rating by
changing the existing burner orice to a smaller size. Generally,
input should be reduced 4 percent for each 1000 feet above sea
level. However, if the heating value of the gas has been reduced,
this general rule may not apply. Check with local gas utility for proper
orice size identication.
For Canadian high altitude applications, this appliance is suitable for
installation at elevations between 0 feet (0m) and 4,500 (1,370m)
without change.
When installing this unit at an elevation above 4500 feet (1,370m)
(in Canada), check with local authorities.
Consult your local gas utility for assistance in determining the proper
orice for location.
not, the entire unit may move when you adjust the controls.
Movement of unit may cause shifting of the gas logs which
leads to improper burning.
1. Center the gas burner in the replace or rebox. The grates
must clear the replace or rebox screen.
2. An anchor hole is provided in the two bottom side members of
the grate frame. After centering the grate correctly, mark the
hole positions on the replace/rebox oor. Drill two (2) 5/32"
diameter holes approximately 1-1/2" deep for masonry screws
or 1/8" hole for sheet metal screws.
3. Anchor the grate to the replace/rebox oor using the screws
provided.
Proper installation of the grate is essential to prevent any move-
ment of the gas logs and controls during operation.
