Before Installing; Iii Before Installing - Crown Boiler FWZ060 Installation Instructions Manual

1) Safe, reliable operation of this boiler depends upon installation by a professional heating contractor in strict accordance with
this manual and the requirements of the authority having jurisdiction.
• In the absence of an authority having jurisdiction, installation must be in accordance with this manual and the latest
edition of Installation of Oil Burning Equipment (ANSI/NFPA31). Installations in Canada comply with the requirements
of CSA B139-04 – Installation Code for Oil-burning Equipment.
• Where required by the authority having jurisdiction, this installation must conform to the latest edition of Standard for
Controls and Safety Devices for Automatically Fired Boilers (ANSI/ASME CSD-1).
2) Make sure that a properly sized chimney is available which is in good condition. Consult the authority having jurisdiction,
Part VI of this manual, and ANSI/NFPA31 for additional information on venting requirements.
3) Make sure that the boiler is correctly sized:
• For heating systems employing convection radiation (baseboard or radiators) use an industry accepted sizing method
such as the I=B=R Guide RHH published by the Air-Conditioning, Heating and Refrigeration Institute (AHRI).
• For new radiant heating systems refer to the radiant tubing manufacturer's boiler sizing guidelines.
• For systems including a Crown Mega-Stor indirect water heater, size the boiler to have either the Heating Capacity re-
quired for the Mega-Stor or the I=B=R Net Rating required for the heating system, whichever results in the larger boiler.
• For systems that incorporate other indirect water heaters, refer to the indirect water heater manufacturer's instructions for
boiler output requirements.
4) In some cases, boilers installed at altitudes above 2000ft may require a different burner configuration from that at sea level.
Consult the local Crown representative for more information.
Two problems arise when any oil-fired appliance is power vented:
• There is sometimes an accelerated rate of soot buildup on the oil burner cad-cell, spinner etc.
• There is a potential for severe damage to the side of the structure in the event that the boiler
operates at a high smoke level. This can happen for many reasons, some of which are out of the
control of both the installer and appliance manufacturer.
Crown Boiler Company recommends the use of a chimney to vent the FWZ series boilers. If
a power venter must be used, it is the responsibility of the installer and power vent manufacturer to
"engineer" the power vent system. Crown Boiler Company will assume no responsibility for damage
to siding, etc. from a power vented oil-fired boiler. This applies regardless of the cause of the sooting.
