Set Appliance State:
| Isolate Mains Power to appliance as per TOPs P4 |
CH Demand
CH Temperature Control set to approx. 12 o'clock position
Attach pressure gauge to gas valve pressure outlet test point
Attach pressure gauge to gas valve pressure outlet test point
| WARNING! - Mains voltage is expected during test follow TOPs P4 live testing procedure |
Observation:
Allow burner to ignite and establish.
Burner pressure will slowly ramp up to maximum after approx. 1 minute.
Once the CH flow temperature reaches approx. 60°C
does the burner pressure start to modulate down?
Note:
When pressure gauge is removed the pressure test point
should be tightened and checked for gas tightness.
