Midco RS40 - Manual (Page 10)

Keep the area around the burner clear and free of combustible materials, gasoline and other
flammable liquids or vapors. Do not obstruct burner air inlet or ventilation air.
?? The motor features permanently lubricated ball bearings and requires no routine oiling
maintenance.
IMPORTANT: Check the burner flame periodically. A proper NATURAL gas flame will appear
blue at the burner face with orange and yellow tips. A proper PROPANE gas flame will
appear blue at the burner face with yellow tips. If the flame is too rich, it will appear billowy
and yellow with hazy tips. If too lean, it will appear short and all blue. If the flame does not
appear proper, CONTACT A QUALIFIED SERVICE TECHNICIAN FOR CLEANING,
READJUSTMENT AND/OR REPAIR.
WARNING: If any flame is observed when the burner is on standby, or if the
ignition spark or valve operator is heard to come on before the motor reaches
operating speed, immediately turn off the Main Manual Shut-off Valve and burner
power. A dangerous condition has developed and must be corrected. CONTACT A
QUALIFIED SERVICE TECHNICIAN FOR CLEANING READJUSTMENT AND/OR
REPAIR.
WARNING: If PROPANE gas is used and the burner is located in a basement,
crawl space or confining space, contact your gas supplier about installing a GAS
LEAK warning device. PROPANE gas is heavier than air and can settle in low areas or
confined spaces. This would create a danger of explosion or fire. If you suspect a gas
leak, follow instructions on front cover of this manual.
