INTRODUCTION
The Lochinvar Herald range is a floor standing gas fired condensing boiler. The equipment comprises a
stainless steel radial burner assembly and a heat exchanger that permits fully condensing operation.
The burner is initiated by a full electronic ignition sequence control that incorporates a spark ignition and a
flame rectification device for supervision of the flame.
The output from the boiler is regulated by a variable speed combustion fan and gas/air ratio controls to maintain
the correct combustion at all levels of modulation. This configuration allows modulation down to 20% of the
rated output.
For the correct operation of the boiler, it is essential that a suitably sized pump is utilised to maintain a constant
water flow rate through the heat exchanger. A suitable shunt pump is available as an ancillary option from
Lochinvar Ltd. See section 14.2.2
This equipment is intended for use on Group H Natural Gas (2
nd
Family) and LPG propane (3
rd
Family). The
information relating to propane firing is to be found in Section 18.0: LPG FUEL. This equipment MUST NOT
use gas other than that for which it has been designed and adjusted.
This equipment must be installed by a competent person, registered with a H.S.E. approved body. All
installations must conform to the relevant Gas Safety and Building Regulations. Health & Safety requirements
must also be taken into account when installing any equipment. Failure to comply with the above may lead to
prosecution.
If the equipment is to be connected to an unvented (pressurised) system, care must be taken to ensure all
extra safety requirements are satisfied should a high or low-pressure condition occur in the system.
The equipment is designed for direct connection to a flue system.
