The following tasks must be performed by a qualifi ed
technician.
Gasket Seal and Glass Assembly Inspection
Frequency: Annually
By: Service Technician
Tools needed: Protective gloves, drop cloth and a stable
work surface.
• Inspect gasket seal and its condition.
• Inspect fi xed glass assembly for scratches and nicks that
can lead to breakage when exposed to heat.
• Confi rm there is no damage to glass or glass frame.
Replace as necessary.
• Verify that fi xed glass assembly is properly retained and
attachment components are intact and not damaged.
Replace as necessary.
Logs
Frequency: Annually
By: Service Technician
Tools needed: Protective gloves.
• Inspect for damaged or missing logs. Replace as necessary.

causing sooting. Correct as necessary.
Firebox
Frequency: Annually
By: Service Technician
Tools needed: Protective gloves, sandpaper, steel wool,
cloths, mineral spirits, primer and touch-up paint.
• Inspect for paint condition, warped surfaces, corrosion
or perforation. Sand and repaint as necessary.
• Replace appliance if fi rebox has been perforated.
Surface cracking or crazing of fi rebrick material is normal
and expected. The following types of cracks are acceptable
and do not require replacement of the unit or the fi rebox:
• Cracks that do not propagate entirely through the
material.
• Light fracture lines or "spider-webbing" on the surface of
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.
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.
12 Quadra-Fire • QVI-35FB-S • 2178-900 Rev. B • 12/08
Inspection for cracking should be run when the appliance is
cool. Cracks tend to close as the appliance heats up.
Control Compartment and Firebox Top
Frequency: Annually
By: Service Technician
Tools needed: Protective gloves, vacuum cleaner, dust
cloths
• Vacuum and wipe out dust, cobwebs, debris or pet hair.
Use caution when cleaning these areas. Screw tips that

size is correct. See Service Parts List for proper orifi ce
sizing.
• Verify manifold and inlet pressures. Adjust regulator as

for proper pilot fl ame pattern. Clean or replace orifi ce
spud as necessary.
• Inspect thermocouple/thermopile for soot, corrosion
and deterioration. Clean with emery cloth or replace as
required.
• Verify thermocouple/thermopile millivolt output. Replace
pilot as necessary.
