INSTALLATION
Unpacking and Inspection
• The unit was test-operated and inspected at the factory prior to crating and was in operating condition.
• It is important to note when uncrating the unit that shipping brackets are attached with cabinet screws. When
removing shipping brackets, re-insert ALL screws into the cabinet.
• If, upon removing it from its crate, the unit has been found to have incurred any damage in shipment, document
the damage with the transporting agency and contact an authorized Factory Distributor. If you are an authorized
Distributor, follow the FOB freight policy procedures.
• A conversion kit is included with the heater for converting for use with propane (refer to Converting Unit from
Natural Gas to Propane. section).
Pre-Installation Checklist
Check the rating plate for the gas specifications and electrical characteristics of the heater to ensure that they
are compatible with the gas and electric supplies at the installation site.
Read this manual and become familiar with the installation requirements of your particular heater.
If you do not have knowledge of local requirements, check with the local gas company or any other local agencies
who might have requirements concerning this installation.
Before beginning, make preparations for necessary supplies, tools, and manpower.
Check to see if there are any field-installed options (refer to Table 11) that need to be assembled/installed
prior to unit installation. Ensure that all options ordered are at the installation site. Instructions are in this
manual or in the option package (option packages are shipped separately).
