Any help would be appreciated...
I have a Lennox Model # G1603/4 100-1 S# 5887G10452 gas furnace. I powered up for the 1st time this fall and smelled gas in the basement. I observed that only 1 of 4 burners (the 2nd from left with the igniter) was firing. The others were not not lighting. Called gas co., shut off furnace and waiting for gas co. tech to arrive Wednesday.
Any thougts? Does position of burners in chambers matter? Do they need to be placed a certain way in each chamber so ignition travels from burner to burner? Or..is this a problem with a bad component and inadequate ignition?
