Unpacking
and
Inspection
Check the heater for any damage that may have occurred in shipment!
If damage is found, file a claim with the transport company. Your unit was
inspected and tested at the factory prior to crating and was in perfect condi-
tion at that time. Open the boxes and verify receipt of all parts.
To protect the unit during shipping, the blower model (RAD) has special
supports that must be removed before installation.
• Blower support legs - Remove the four blower support legs and
screws.
• Check Belt Tension - Belt should be able to be depressed 1/2”- 3/4”
(13-19mm) - See illustration. If the belt
does not have proper tension, adjust by
means of the adjusting screw on the
motor base. After proper tension is
achieved, tighten the lock nut on the
adjusting screw.
Replace the belt guard.
WARNING: Care should be exercised to ensure that an
adequate supply of combustion air is available and free
to enter the air openings on all units. Room openings must
equal one square inch per each 1,000 BTU heat input.
3/4 (19mm)
Fan Models (RA) use plastic cable ties to support the fan motors during
shipment. Cut and remove prior to installation.
