2.2 Throw

Immediately upon uncrating the unit, check for any damage that may have been

incurred in shipment. If any damage is found, immediately document the damage

with the transporting agency and contact an authorized Reznor Distributor. If you are

an authorized Distributor, follow the FOB freight policy procedures as published by

Reznor, LLC. The unit was inspected and tested at the factory prior to crating and was

in operating condition at that time.
To prevent damage to the painted cabinet, it is recommended that the crate bottom be

left in place until after the unit has been suspended.
A cleaning rake base is included with all units. If the heater is being installed in Canada,

an Option DB1 barometric draft regulator is required. The option kit is shipped sepa-

rately. The installation could also include a variety of other shipped-separate options.

Be sure that all optional components to be used in the installation are at the job site.

4.1 Clearances

Clearance to combustibles is defined as the minimum distance from the heater to a

surface or object that is necessary to ensure that a surface temperature of 90°F above

the surrounding ambient temperature is not exceeded.
The heater should be suspended at a height so that the heat exchanger cannot be

touched. For additional information on installation clearances, refer to CAN/CSA-B139,

"Installation Code for Oil Burning Equipment", Paragraph 8 -- Installation Clearances.
