Slant/Fin Liberty L-20 observation door repair
I recently had my boiler inspected and in the process the service tech broke off the observation door on the front burner plate. I'm not sure if he did something wrong (he seemed to be in a rush to get my inspection done) or if the door was just in bad shape and it was inevitable, but regardless the door has been broken off the front burner mounting plate. He did not go into detail as far as what happened but I believe he had said something to the effect "the bolts broke off". I was not around to witness the damage myself, but when I got home I found he had placed a length of metal strapping from the left side to the right side of the boiler screwed in with sheet metal screws across the face of the observation door caked in furnace cement. With all the furnace cement caked on the door it is impossible to see anything (I can't see the condition of the door or the location of broken bolts). I have to remove the burner and front burner mounting plate this week in order to replace the firebox insulation (rear target wall, front refractory, floor blanket) so I was wondering if anyone could shed some light on the repair procedure I'm in for. I have gone ahead and ordered a new door kit which consists of 3 new bolts, the door, and what looks to be a gasket of some sorts. I would like to know what to expect as far as repairing this problem goes because I obviously can't have the boiler inoperable for very long since it's winter time here in MA. I'm guessing it will involve me trying to drill out some broken bolts but I'm not 100% sure. If anyone could help point me in the right direction i would certainly appreciate it. I was also looking for any info/tips/tricks on the burner removal procedure (how to remove burner, fuel lines, and any possible electrical connections). Once again I would greatly appreciate any information, suggestions, or step by step directions anyone might have. Thanks, Dan
