MAINTENANCE AND INSPECTION
It is recommended that maintenance and inspection is done on a scheduled basis. Maintenance
requirements will naturally vary widely for each installation and with specific operating conditions. It
is suggested that a complete inspection be performed with necessary maintenance at the end of
the first week, the first month, the first three months, and the first six months. These inspections
will be indicative of how often future maintenance will be necessary. Suggested maintenance and
inspection items are shown on the following pages.
WARNING
The user has the responsibility for establishing a program of inspection, testing, and maintenance
with documentation performed at least annually for every gas safety component (Reference NFPA
86
– Ovens and Furnaces, 5-2.5.2)
EVERY MONTH
A. Inspect the combustion air filter. Clean or replace as required.
B. Check for gas leaks using an approved leak detector.
EVERY 3 MONTHS
A. Units equipped with ball bearing motors are factory greased and should be re-lubricated with
a high-grade ball bearing grease.
NOTE:
Most units are equipped with permanently lubricated bearings and no lubrication is
required. All motors should be examined on an individual basis.
When adding lubricant:
1. Remove filler plugs at the bearings and install grease fittings suitable to your grease gun.
Also remove the drain plugs at the bearings.
2. Add ball bearing grease until all of the old grease is expelled through the drain hole.
3. Run motor with drain plug removed to eliminate excess grease.
4. Clean and replace drain plugs.
B. Check motor(s) amperage
C. Check all electrical connections to make sure that they have not become loose, especially those
connections at motor starters.
D. Check all mechanical connections i.e. collar setscrews, etc., to make sure that they have not
become loose.
