Braemar Fault Code 45

Fault: Combustion air pressure too low during run.

Potential Cause (Technical Use Only: Potential remedy):

  • Swarf obstruction combustion fan pressure tapping.  Check both ends of pressure tapping – clear obstruction or replace pressure tapping. 
  • Condensate intermittently blocking combustion fan suction hose.  Clear blockage.  Check flue condensate drain fitted correctly (condensing models only). 
  • Flue partly blocked, making system more susceptible to wind effects.  Check and clear blockage, check flue cowl is not pushed on too far. 
  • Severe wind on flue terminal, or poor flue terminal location (eg, too close to roof).  Check flue terminal location – re‐ locate if necessary.
