Claims
- 1. A method of fabricating and testing a fuel-fired heating appliance having a side wall portion with an opening therein, and a combustion chamber opening outwardly through said opening, said method comprising the steps of:providing an access door/burner assembly including an access door member having a burner lighting and test opening therein, main and pilot fuel supply tubes sealingly extending through and anchored to said access door member, and main and pilot fuel burners supported on said main and pilot fuel supply tubes for movement with said access door member; positioning said main and pilot fuel burners within said combustion chamber; installing said access door member on said side wall portion to cover said side wall portion opening; inserting a lighting structure into said combustion chamber through said burner lighting and test opening in the installed access door member; using the inserted lighting structure to light and test said main and pilot fuel burners; withdrawing the inserted lighting structure from said combustion chamber through said burner lighting and test opening; and snap-fitting a sight glass structure into said burner lighting and testing opening after said withdrawing step.
- 2. The method of claim 1 wherein:said fuel-fired heating appliance has a thermocouple wire and an igniter wire, said access door member has a pass-through tube extending therethrough, and said method further comprises the step of sealingly extending at least one of said pilot fuel supply tube, said thermocouple wire and said igniter wire through said pass-through tube.
- 3. The method of claim 2 wherein said expending step is performed by:providing a resilient sealing plug member, extending said at least one of said pilot fuel supply tube, said thermocouple wire and said igniter wire axially through an interior portion of said resilient sealing plug member, and placing and wedging said resilient sealing plug member within said pass-through tube.
- 4. The method of claim 3 further comprising the step of:fixedly securing said sealing plug member to at least one of said thermocouple wire and said igniter wires.
- 5. A fuel-fired heating appliance fabricated and tested by the method of claim 4.
- 6. The method of claim 3 wherein:said providing step is performed by providing a tapered cylindrical resilient plug member having a radially split configuration in which first and second halves of said plug member are foldable about a peripheral flap portion of said plug member between an open position in which flat sides of said first and second halves extend in opposite directions from said peripheral flap portion, and a closed position in which said flat sides face and abut one another, said flat sides having recesses therein which are configured to receive side portions of said at least one of said pilot fuel supply tube, said thermocouple wire and said igniter wire, said extending step is performed by placing side portions of said at least one of said pilot fuel supply tube, said thermocouple wire and said igniter wire in associated ones of said recesses with said sealing plug member in said open position, and then folding said sealing plug member to said closed position, and said coaxially placing and radially wedging step is performed with said plug member in said closed position.
- 7. A fuel-fired heating appliance fabricated and tested by the method of claim 6.
- 8. A fuel-fired heating appliance fabricated and tested by the method of claim 3.
- 9. A fuel-fired heating appliance fabricated and tested by the method of claim 2.
- 10. A fuel-fired heating appliance fabricated and tested by the method of claim 1.
