5.Inspect the element for damage or degradation. Although small hairline cracks will not affect per- formance, the element should be essentially intact. If the element is broken in pieces or has sections missing, it should be replaced. Call your local Ver- mont Castings Authorized Dealer for a replacement element.
While the catalytic element is removed, check the condition of the secondary air probe. Use an inspec- tion mirror to locate the probe within the combustion chamber. (Fig. 46) The probe should extend 1” to 1¹⁄₂” into the chamber and show no signs of excessive de- terioration, such as warping, corrosion, or short length. A damaged secondary air probe can affect catalytic performance. If the probe needs replacement, contact your local dealer.
