There is still a lot of mechanical satisfaction to be had from maintaining and fine-tuning today’s gas appliances. As an example, in part one (Jan. 15), I described a service contract call for one particular customer, a retired English teacher named Mrs. Johnson.
Many techs who service gas appliances reminisce about the days of the pilot and belt-drive blower - how wonderful it was to have belts to adjust, pilot orifices to clean, ribbon burners to wash, bearings to oil, and air shutters to adjust to get just the perfect blue cone in the flame with streaks of orange appearing intermittently at the tips.
