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.
