J&R 700E - Preventive Maintenance Check List; Bearings; Chain; Exit Flue Cleaning

(e) Leave the racks in place and fill the pit with a hot water/oven
cleaner solution up to the middle of the exit flue opening. Heat the
pit up to 250° and allow the racks to revolve. Continue for at least
4 hours, drain and rinse the pit thoroughly.
Drain the washings from the pit through the drain valve (see Figure 1). If a
floor drain is not adjacent to the drain valve, attach a hose or pipe to the valve
and extend it
over to a suitable drain.
PLEASE NOTE:
Methods (a), (b), and (c) are operable only if pit is cleaned every week. If several
weeks pass between cleanings, the cleaner will not penetrate and remove the
residue.
PREVENTIVE MAINTENANCE CHECK LIST
EVERY 6 MONTHS
1. Inspect and repair as needed all gaskets. This includes the front door
gaskets, the two bypass gaskets, and the exit flue gasket.
2. Inspect and adjust, repair, or replace the front door latch.
3. Check the temperature control mechanism for proper operation. Cycle
the thermostat and make sure the combustion air damper and exit flue
damper are opening and closing (tightly). Lubricate all linkages at the
rear of the pit. Remove the thermostat faceplate and spray the moving
parts with a spray lubricant.
EVERY 45 DAYS
BEARINGS Remove the access panel below the front oven doors (or, with
newer units, open the lubrication access door on the access panel). The
rotisserie bearings have lubrication extensions that terminate with grease
fittings locatednear the motor starter enclosure. Use a high temperature
grease (SuperLube Synthetic Grease is recommended) and a cartridge-type
automotive grease gun.NOTE: Low temperature grease will harden at high
temperatures and damage the bearings.
CHAIN Lubricate the chain with the same high temperature grease. Remove
the access cover on the drive side adjacent to the front of the unit, or remove
the front access panel below the pit doors to access the chain. Check the chain
tension and adjust as necessary.
EXIT FLUE CLEANING Clean this flue thoroughly from inside the cooking
compartment or remove the rear access cover adjacent to the flue and clean it
from the rear of the pit with the flue damper open.
NOTE: If this flue is not kept clean, the solids accumulation can retard the
passage of smoke from the oven to the stack, causing soot and/or
temperature control problems.
