Questions about this item

How is the 67L70 pilot assembly installed on a Lennox LMDV3530CNM fireplace?

Turn off the gas supply, remove the front glass panel, disconnect the old pilot tubing and thermocouple leads, mount the new assembly using the original bracket screws, reconnect the tubing and leads, then test for leaks before relighting.

What maintenance will the 67L70 pilot assembly need after installation?

Inspect the pilot flame annually for a steady blue pattern, clean the orifice with compressed air if the flame becomes yellow or noisy, and verify the thermocouple output stays within the valve’s specified millivolt range.

What is the first limit that appears during sustained operation of the 67L70 pilot assembly?

The pilot orifice can carbonise over long heating seasons, reducing gas flow and causing an unstable flame that eventually fails to keep the thermocouple hot enough to hold the gas valve open.
