REPAIRS, SERVICE AND/OR COMMISSIONING OF GAS APPLIANCES MUST ONLY BE
PERFORMED BY A SUITABLY LICENSED PERSON
RECOMMENDED SERVICE PROCEDURES
It is a requirement of Raypak and all gas authorities that the heater be serviced at least once
per year. Where it is used in a specific application, e.g. mechanical heating, it would be
practical to perform the service at the commencement of the heating season, or at any time
there may be an indication of a problem.
In some installations, due to the appliance location and/or workload it may be necessary to
perform a service every six months.
Contact your nearest Rheem Service Department or Accredited Service Agent to arrange a service.
