Maintaining and Servicing Your Fireplace
Fireplace Maintenance
Although the frequency of your fireplace servicing and main-
tenance will depend on use and the type of installation, you
should have a qualified service technician perform an appli-
ance check-up at the beginning of each heating season.
See the table below for specific guidelines regarding each
fireplace maintenance task.
IMPORTANT: TURN OFF THE GAS BEFORE SERVICING
YOUR FIREPLACE.
Replacing old ember material
Frequency: Once annually, during the checkup.
By: Qualified service technician.
Task: Brush away loose ember material near the burner.
Replace old ember material with new dime-size and shape
pieces of Glowing Ember (050-721). Save the remaining
ember material and repeat this procedure at your next
servicing. For more information, see Placing Ember
Material.
Cleaning Burner and Controls
Frequency: Once annually.
By: Qualified service technician.
Task: Brush or vacuum the control compartment, fireplace
logs and burner areas surrounding the logs.
Cleaning Flame Sensor Rod (IPI Systems)
Frequency: Annually.
By: Qualified service technician.
Task: Make a visual check of the straight flame sensor rod
(see Figure 9). Use emery cloth to carefully remove any
existing film or white deposits.
Checking Flame Patterns, Flame Height
Frequency: Periodically.
By: Qualified service technician/Home owner.
Task: Make a visual check of your fireplace's flame patterns.
Make sure the flames are steady - not lifting or floating.
See Figure 15. The thermopile/thermocouple tips should
be covered with flame.

Checking Vent System
Frequency: Before initial use and at least annually
thereafter, more frequently if possible.
By: Qualified service technician/Home owner.
Task: Inspect the external vent on a regular basis to ensure
that no debris is interfering with the flow of air. Inspect entire
vent system for proper function.
Cleaning Glass Door
Frequency: After the first 3 to 4 hours of use. As neces-
sary after initial cleaning.
By: Home owner.
Task: Remove and clean glass after the first 3 to 4 hours of
use. After the initial cleaning, clean as necessary, particu-
larly after adding new ember (flame colorant) material. Film
deposits on the inside of the glass door should be cleaned
off using a household glass cleaner. NOTE: DO NOT handle
or attempt to clean the door when it is hot and DO
NOT use abrasive cleaners.
NOTE: Under certain weather conditions, some water may
accumulate inside the fireplace. This is normal and ex-
pected. The control compartment contains two removable
drip pans that may be cleaned as necessary (see Figure
16). Excess moisture can be eliminated by burning the fire-
place for a few hours.
