Blockage in vent.
-
Remove blockage. In really cold conditions, ice
buildup may occur on the terminal and should be
removed. To minimize this from happening again,
it is recommended that the vent lengths that pass
through unheated spaces (attics, garages, crawl
spaces) be wrapped with an insulated mylar sleeve.
Prevent sleeve from sagging. Contact your local
authorized dealer for more information.
Compromised venting.

Check venting system parameters (seal, length,
rise, etc.).
GLASS EMBERS ONLY:
Too many glass embers.
-
Re-distribute glass embers so that only a single
layer is over top of the burner tube.
Main burner goes
out: pilot goes out.
Vent recirculation.

Check joint seals and installation.
