    Westinghouse cannot anticipate every circumstance that might involve a potential hazard. Each installation has its own specialized characteristics, requirements, and possible hazards. Therefore, all possible incidents are not included in these warnings. Proper and safe installation, operation, and service are the responsibility of the professional service technician.

  • Page 9: Improper Combustion

    Due to the low water content of the appliance, improper sizing of the appliance with regard to heating system load will result in excessive cycling and accelerated component failure. Westinghouse DOES NOT warrant failures caused by improperly sized appliance applications. DO NOT oversize the appliance to the system. Modular appliance installations greatly reduce the likelihood of appliance oversizing.
