Service Instructions
1. Close the fuel supply valve to the heater before
servicing unless it is necessary to have it open for
your service procedure.
2. For reassembly, reverse the respective service
procedure. Ensure gas connections are tightened
securely.
3. After servicing, start the heater to ensure proper
operation and check for gas leaks.
4. Clean the heater’s orifice 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 combustion or ignition problems. Replace
the orifice if it cannot be cleaned properly.
