input in British thermal units per hour (Btu/hr).
5. Orifice Size (For Gas Dryers) – Gives the number drill
size used.

6 Months
Inspect and remove lint accumulation in customer furnished
exhaust ductwork system and from dryer’s internal exhaust
ducting.
NOTE: The accumulation of lint in the exhaust ductwork can
create a potential fire hazard.
Do not obstruct the flow of combustion and ventilation air.
Check customer furnished back draft dampers in the
exhaust ductwork. Inspect and remove any lint
accumulation, which can cause the damper to bind or
stick.
A back draft damper that is sticking partially closed can
result in slow drying and shutdown of the heat circuit safety
switches or thermostats.
If the hi-limit trips due to a high temperature occurrence,
you must disconnect power before resetting. To reset,
press and release the reset button, which is located on the
left side of the burner box, looking at the burner from the
back of the dryer.
When cleaning the dryer cabinet(s), avoid using harsh
abrasives. A product intended for the cleaning of
appliances is recommended.
Check all V-belts for tightness and wear. Retighten, realign,
or replace if required.
NOTE: V-belts should be replaced in matched sets (pairs).
Adjustments
7 Days After Installation
and Every 6 Months Thereafter
Inspect bolts, nuts, screws, setscrews, grounding
connections, and nonpermanent gas connections (unions,
shutoff valves, and orifices). Impellor/fan V-belts, along with
the motor and drive belts should be examined and replaced
if necessary. Tighten loose V-belts when necessary.
Complete operational check of controls and valves. Complete
operational check of all safety devices (door switches, lint
drawer switch, sail switch, burner, and hi-limit thermostats).
NOTE: The impellor/fan on the blower motor must be
inspected and cleaned every 6 months.
Lubrication
All the tumbler drive shaft and idler shaft bearings must be
lubricated every 3 months. Use Shell Alvania #2 grease or
its equivalent. Lubrication is necessary or premature bearing
failure will be the result.
The motor bearings are permanently lubricated and do not
require service.
