WARNING
Fire and Explosion Hazard
■ Do not disassemble or attempt to repair any
heater components or gas train components.
■ All component parts must be replaced if defects
are found.
■ Failure to follow this warning will result in fire or
explosions, causing property damage, injury, or
death.
1. Close the fuel supply valve to the heater and
disconnect the heater's electrical supply before
servicing unless it is necessary to have the valve
open and electrical supply connected for your
service procedure.
2. Open the burner box for access to control com-
ponents. Close and latch after servicing.
3. For reassembly, reverse the respective service
procedure. Ensure gas connections are tight-
ened securely.
4. Clean the heater's burner orifice and pressure
switch orifices with compressed air or a soft,
dry rag. Do not use files, drills, broaches, etc. to
clean the orifice hole. Doing so will enlarge the
hole, causing ignition or combustion problems.
Replace the orifice if it cannot be cleaned
properly.
5. Disconnect appropriate component electrical
leads when servicing. After servicing, light
the heater to ensure proper operation
and check for gas leaks.
Igniter
The tip of the igniter is exposed to a harsh environ-
ment consisting of high temperatures and combus-
tion products. Periodic servicing is required.
