Flame Troubleshooting, cont.
2. If vertically vented, a restrictor strap is required to reduce the volume of combustion air, which in turn
will raise the flame height.
3. If vented vertically with a horizontal run included; determine if the rise to run is close to the venting graft
maximum, i.e. you are using the maximum horizontal for the amount of vertical. If the vertical rise is much
greater than the horizontal run the restrictor strap may be installed to slow combustion air. If this method
is used, light the stove for the first time and watch for flame lift (blue flame 1-30 seconds lifting off burner
and hovering in the middle of the firebox.) If this is visible
immediately
shut the gas valve off and remove
the restrictor strap. Flame height can now be further adjusted by using shutter adjustment previously
described in step 1.
Tall Stringy Flame
Single tall flame
1. If there is a single flame that is tall and stringy and the other flames look acceptable, 1-3 nuggets can
be placed on top of the flame origin. This will increase glow at this point and cause the flame to turn semi-
transparent. If nuggets are added to the rear left of the firebox, make sure that the pilot flame is not
blocked from lighting the burner.
Many tall flames
1. If the appearances of the majority of the flames are tall and stringy, the entire burner needs more
primary air. This can be accomplished by turning the shutter adjustment counter-clockwise. See Figure
A on previous page.
