6.2 Testing safety valve
B Make sure that no people are in the discharge area of
the safety valve.
B Raise the lever on the safety valve.
The safety valve must open and release pressure. If the
safety valve fails to release excess pressure, it must be
replaced, because otherwise system components may be
damaged by excessive operating pressure.
6.3 Checking position of heat exchanger baffles
Prior to commissioning, check that the heat exchanger
baffles are in a horizontal position:
B Open burner door by removing the two hex bolts at the
sides.
The GB125 comes equipped with 2 heat
exchanger baffles at the lower position. Do
not install additional heat exchanger baffles
(Fig. 33).
B Slightly withdraw the heat exchanger baffles [1] from
the heat exchanger.
B Adjust the heat exchanger baffles [1] to a horizontal
position and push them back into the heat exchanger.
B Close the burner door and secure with the two hex
bolts (tighten to approx. 90 inch - lbs.). Tighten the hex
bolts evenly so that the burner door seals properly.
