You aren't suggesting that they can skip the annual service on the
boiler are you??? Gas may not need to have a nozzle and filter changed
like oil, but it certainly needs an annual service just like oil,
particularly for a commercial sized unit like the OP has. The cost of
that annual service isn't going to be any different since a nozzle and
filter account for about $10 worth of materials.
