TL109 Burner Tray Kit
The TL109 Burner Tray Kit is designed for use in HW/HWC’s that were
originally equipped with single port inshot burners. Four kits are available,
one for each natural gas heating input rating as follows:
26,000 BTUH (3 main burners)
38,000 BTUH (4 main burners)
51,000 BTUH (5 main burners)
64,000 BTUH (6 main burners)
Each kit includes:
An assembled burner tray including manifold, natural gas orifices and
3, 4, 5 or 6 main burners (depending on heating input rating
A three-rod combination igniter/sensor
Installation instructions
The burner tray assembly included in this kit can be used with either the
Fenwal remote sense ignition control (which uses a separate flame
sensor lead), or the more recent Fenwal local sense ignition control
(which does not use a separate flame sensor lead). When used with the
remote sense ignition control, the three-rod combination igniter/sensor in
the kit effectively makes this a “local sense” system.
