I need to replace the gas log starter pipe in my fireplace. I have the new ready to go, fits perfectly. My question is... which way do you face the holes in the pipe to allow the flame out?? I am thinking if straight up, it will fill up with ash and clog.

Forward, facing toward the rear of the fireplace or at an angle either way??

Yeah, I forgot to take note of how the old was positioned.

to front with a little past center like clock at 3;30 way I have seen then done when they only have 1 set of outlet holes.

mine is straight up,
and it clogs up from some times, but has been working for 10 years

Twards the rear seems to be the way ours is.

if its just for a starter either a little front or rear, won't matter.
angle it so it hits the logs the best when they are stacked.

After further research, I found pointing towards the rear at a 30 degree angle upward is what was recommended. Works good so far.

I do this to give the fire a boost when I first light it,
If you have the folding glass doors, when you close them leave a space of 2 inches between the doors in the center it will act as a bellows and create a draft that will help the fire go, but only leave then that way for 10 minutes or so, you can tell when fire gets going.
