SUBMERGED boilers and water heater. what absolutely needs to be replaced?
HI. I'm a heating contractor in NYC. I live in the Rockaways on Long Island. I have lots of customers who both Boiler and water heater have submerged either partially, some fully in salt water. I'm working on one customer"s boiler and told him, I'm replacing all controls electrical, gas valve, pump etc that have been under water. am cleaning up all burner tubes. After replacing everything it still isn't lighting off smoothly all the time. I wont let him use it until its burning properly. Its natural gas.
On the GAS end: I replaced the gas valve and thermocouple. I removed the pilot orifice- it was clean. I emptied out water from the pilot tubing and blew out what ever water was left. I removed all the burners tubes and emptied them out from water and wiped them down and put them back. I cleaned the burner manifold tube and soaked the water as much as possible with paper towels and cleaned out the burner manifold orfices. The pilot is burning nicely a clean blue flame.
PROBLEM :When I turn the boiler on, on a call for heat when the main valve opens up some of the time theres a delay of 2-3 seconds and the flame lights with a small boom/explosion, but sometimes it works smoothy.
I tried to adjust the pilot flame thinking that the pilot flame thinking that the pilot flame was a little small and I found it already at its maximum before I touched it.
I obviously did not leave the customer like that. Shut down boiler.That's where I ended last night
I'm going back shortly. my plan is totake a new change and put in a new VR8300A which is its gas valve and to soak the burner tubes in warm water and wipe them down. Any information anyone has as to what's wrong would help me greatly. I've never had a flood situations like these in my 6 years servicing people so any pointers would be greatly appreciated, Thank you.
