SEALED COMBUSTION CHAMBER

The combustion chamber is factory sealed around the flame arrestor and the upper and lower perimeter of

the chamber. Access for service is provided through an inner door as with current product. However, this

inner door is now sealed with; a door gasket, a pilot assembly grommet type seal, and a main burner tube

boot/sleeve type seal.

The three seals on the inner door should be checked every time any service is performed. The sight glass

should be checked to insure it is not damaged or missing. The pilot tube and thermocouple routing should

be straight (not bent at an angle close to the surface of the seal) as it passes through the pilot assembly

seal.
