1. Poor fuel quality
2. Fireplace venting system
not drafting properly
3. Excessive ame impinge-
ment or blockage
4. Improper fuel/air mixture
5. Excessive gas supply/pres-
sure
1. Passage of air/gas across
irregular surfaces
1. Incorrect gas supply or
pressure
2. Blocked burner orifice or
burner manifold ports
3. Improper burner orifice
size
1. Ignitor electrode not con-
nected to ignitor cable
2. Ignitor cable pinched or
wet
3. Bad ground on piezo ignitor
4. Broken ignitor cable
5. Bad piezo ignitor
6. Ignitor electrode broken
7. Ignitor electrode positioned
wrong
REMEDY
1. Contact local natural or
propane/LP gas company
2. Adjust damper wide open
and/or have replace and
venting professionally
cleaned and checked
3. Separate the logs to allow

from the ame pattern and/
or check for proper orice
sizing
5. Preheat ue in very cold
weather
1. Relieve any tight bends or
kinks in gas supply line
1. Check for proper gas sup-
ply pressure
2. Free burner orifice and
manifold ports of any burrs,
paint, or other blockage
3. Verify proper burner ori-
fice sizing (see Figure 2,
page 6)
1. Reconnect ignitor cable
2. Free ignitor cable if pinched
by any metal or tubing.
Keep ignitor cable dry
3. Scrape away paint on brack-
et for better contact with
ground on piezo ignitor
4. Replace ignitor cable
5. Replace piezo ignitor
6. Replace electrode
7. Reposition electrode

Log set is smoking/sooting
excessively
(Note: It is natural and un-
avoidable for vented gas log
sets to produce moderate
levels of carbon (soot) where
flames contact the logs.
This is especially true with
propane/LP gas.)
Burner is excessively noisy
(Note: The movement and
combustion of gas will cre-
ate low, unavoidable levels
of noise.)
Burner ame is too low or
too high
When ignitor button is
pressed, there is no spark
at pilot (GA9050A-1 Only)
