8 Boiler Piping. Install the boiler piping according to the Installation manual furnished with the boiler. The pressure relief and tridicator should be installed on the provided tappings on the furnished supply manifold. The pressure relief should be piped to a suitable discharge. Boiler piping and related connections should conform to accepted industry standards using approved joint sealants and conform with local and State codes. Burner Controls The furnished burner is equipped with a pre-purge and post-purge cycle. The pre-purge is intended to establish airflow through the boiler prior to oil flow to ensure clean combustion under all circumstances. The length of the pre-purge cycle is factory set and does not require adjustment. The post-purge cycle on the burner ensures that after combustion has stopped, the flue products are discharged to the outside and the venting system is fully cleared of all flue products. The post-purge cycle is factory set and does not require adjustment. Fuel Supply Delivery System The fuel line supplying oil to the burner can beset up as either a one pipe or two pipe system. The use of a Garber oil filter at the burner is mandatory to prevent nozzle contamination. 3 Operational Procedure Figure 5: Fuel line installation details.
