C. High Altitude Installations
U.L. Listed gas appliances are tested and approved with-
out requiring changes for elevations from 0 to 2000 feet
in the U.S.A. and Canada.
When installing this appliance at an elevation above
2000 feet, it may be necessary to decrease the input rat-
ing by changing the existing burner orifice to a smaller
size. Input rate should be reduced by 4% for each 1000
feet above a 2000 foot elevation in the U.S.A., or 10% for
elevations between 2000 and 4500 feet in Canada. If the
heating value of the gas has been reduced, these rules
do not apply. To identify the proper orifice size, check
with the local gas utility.
If installing this appliance at an elevation above 4500 feet
(in Canada), check with local authorities.

D. Inspect Firebox
Surface cracking or crazing of firebrick material is normal
andexpected. Thefollowingtypesof cracksareacceptable
and do not require replacement of the unit or the firebox:
• Cracks that do not propagate entirely through the
material.
• Lightfracturelines or “spider-webbing”on the surfaceof
the material.
• Cracks that are less than 1/32 in. wide and less than 3
in. long.
• If cosmetically unacceptable, such cracks may be
repaired with the SRV-PACK service kit. See Service
Parts List.
Cracks that are unacceptable:
• Cracks greater than 1/32 in. wide and 3 in. long are at
risk of growing.
• Cracks that penetrate entirely through the firebrick
material.
Inspection for cracking should be run when the appliance
is cool. Cracks tend to close as the appliance heats up.
