RTG-K-199/160N/X2 – 6 720 813 642 (2022/06)
8.7.1 High pitch noise
1. Verify if correct gas type is selected (see section 6.7).
2. Verify if gas pressure is within specified range (see
section 3.2).
If gas type is properly selected, gas pressure is within range
and the problem persists:
3. Perform the gas and air adjustment as described in
section 8.11.
8.7.2 Low pitch noise
1. Verify if correct gas type is selected (see section 6.7).
2. Verify is gas pressure is within specified range (see
section 3.2).
If gas type is properly selected, gas pressure is within range
and the problem persists:
3. Perform the gas and air adjustment as described in
section 8.11.
8.8 Error codes C1, C2, CF and/or CE
C1, C2, CF and CE errors could be caused by an obstruction in
the venting.
1. Verify if there are any venting obstructions and remove
them if that is the case.
2. Clean or replace the air filter, see chapter 7.1, page 41.
3. Reset the error by holding the On/Off button for 3s.
If there are no obstructions, and the problem persists:
4. Perform the gas and air adjustment as described in
section 8.11.
5. If it is not possible to solve the problem with these
measures and error persists, the burner surface (ceramat)
might be obstructed (e.g. clogging due to dust/particles in
the air). Contact Bradforwhite support line for further
assistance into the diagnosis if your installation fits this
description; in case of confirmation, replace the burner and
revise installation conditions ( section 4.3) to avoid
reoccurrence.
8.9 Error codes EA and/or EC
EA and EC errors can appear if combustion is not properly set.
This could be caused by improper gas supply conditions (gas
pressure and/or gas composition).
1. Verify if correct gas type is selected (see section 6.7).
2. Verify if gas pressure is within specified range (see
section 3.2).
If gas type is properly selected, gas pressure is within range
and the problem persists:
3. Perform the gas and air adjustment as described in
section 8.11.
8.10 Manifold gas pressure
DANGER:
Fatal accidents!
When the appliance is operating with the front cover removed:
▶ Do not stand in front of the appliance.
▶ Avoid breathing the combustion flue gases.
▶ Turn off the appliance and install the front cover assembly
when adjustments and measurement are complete.
The manifold gas pressure measurement is only carried out if it
is necessary to confirm the value from the rating plate.
In case of a high deviation between measured and stated
values, please proceed with Gas/air adjustment (see
section 8.11)
1)
.
▶ Turn Off the appliance.
▶ Remove the front of the appliance (see page 13).

1) Manifold gas pressure from the rating plate is valid for sea
level operation with standard gas pressure and
composition. If operating conditions are different from
those, values from section 8.11 should prevail over
manifold gas pressure to assure a correct appliance tuning.
